Things That Happen Late at Night

all right thank you very much sam so thanks everyone for coming to listen to a bit of my rambling it was a very very very weird thing that happened to get this stock going uh ben has a very strong part and and partial fault i guess in this talk i guess i introduced myself i'm david i've been around the block for a long time and i am working in information security more focused around security management blue team side of the of the technology but i also like toys and i like tools and i like to play a lot and that's what's kind of made up these talks happening because i work in information security i

think it's the pretty much the answer to the why in this slide is i need to do other things rather than my day-to-day work in order to maintain some level of personal balance um to to drive creativity around to to feed the soul and and to be in the zone apparently this is the [Music] technical term if you're a psychologist to get into the zone and that zone is quite important for me it helps me do a lot of things uh in my thinking process it helps it flow um it is absolutely fun for me i am i am a tinkerer i like to thinker i think all the time um and and i think everyone should and i

think everyone could and a lot of questions comes around whether it's 3d printing comments on twitter or the the chaos of my desk which you see it in a much larger picture in a moment and all those things kind of comes together for me to introduce balance and i like to think it also helps me saves a lot on therapy in terms of managing that cost so it was always driven me to why not i i like my creative side as well as i like my analytical side and i i need to nourish them both and ultimately when you drop a square cube of sugar into one cup of coffee and you have that this is this little moment of

satisfaction during the day that helps me feed that soul and because we have a time constraint i have a lot of slides i apologize in advance but um we will go a little bit around what's happening here in the shed in the office in the cinema late at night some of the tools i have and some of the outcome i will be around throughout the day if there's any questions i appreciate there is not a lot of time for questions and i do have a fair amount of pictures to go through so this is how it looks inside you saw my shirt from the outside in the previous slide this is how it was before the some stage of

renovation i saw some people on twitter asking about oh why do i work using the worktube how do i build my my workspace like in my personal opinion whatever works for your work this is slightly chaotic i can't tell you that when you rebuilding your work environment and it starts to look better you actually manage to maintain it over time and this is the reality of my workshop it's constantly ever evolving things are being added more storage more storage most of more tools more storage more things that's happening there we'll go into some of them into more details but that gives you an idea of what does the creative side i guess of my workshop the manufacturing side looks

like of my office this is my desk and this is the office side um some of the reason the desk is there is because it's funny you go to millions of furniture shops like endless amount of furniture shops and you're trying to find a desk you're trying to find a desk which is big enough to fit so many monitors and they don't make them so you have to make your own which which i quite like and again it helps me go and think about cutting wood measuring it maybe painting it and how do i finish it up and in the process i might have figured out this new wording i wanted to put in the new

security policy segment i'm being editing um so i i adopt my storage my furnitures as best as i can to my requirements because it is my shed um and as i said i need the making in order to do the thinking it's kind of really coexist for me so as we talking about all the things that happens late at night this should be a video there yes um this is 3d printing this is where my 3d printing personal 3d printing experience started i saw some online advert it was a 99 pound printer i put the pre-order in and six seven eight nine i don't remember how many weeks later i walked around london and picked a

super heavy box which was started as that today it's kind of evolution of of this beast it's all the same component from the previous model um that was bought for good money this is just made at home um and there are a few other wrong way 3d printers so this is the current 3d printer i have now which because of my virtual background you can't see the plate but it's producing pretty decent prints so i'm quite happy with that and i have a little printer to play and think of which we'll talk about the tinkering in a moment that's my first cnc machine i like machines i like tools as i said at the beginning

this is a very very cheap cnc machine i picked from amazon i believe i highly recommend against buying it even for pcb manufacturing the moto is just embarrassment it's a 12 volt tiny i think it's like 50 watts power this is the new cnc machine in it's mostly current state um as you can see there's some hoses coming out of in additions they are ever evolving um the things that funny enough i end up doing but everyone i know ends up doing i i go to my local hack space you get a new machine you get a new tool you make more tools with it so i made the tool for the tool to make life a little bit easier to make

more tools for the tools so those are all relating to the cnc there's lots of bits and fitting mounting clamps that needs to happen um and sometimes those cnc machines that comes from some country far far far far away um but maybe not the best level of electronics they might have not engineered them themselves and looked at someone else's design and build it they tend to fail a lot of problems that i had with the controller together with the software that led it to be driven by an arduino board on the picture on the right and uh on the the attempt on the mdf this is a one centimeter lens uh concave lens attempt a pick

with the cnc just to make sure the controller is working during the pandemic uh the hackspace was kind of closed down and i realized i can't do any laser etching so i build a laser and engrave it will cut some thin materials i have to probably two and a half millimeters dark materials will go fine um it's to do with the laser module itself um power limitation capability of it but it does move left and right and you can get a graphic file send it through the processor and get it out at the end apart from the computer control devices which are quite exciting i i think of it lots of things i have lots

of tools as you might have seen in the pictures some of my favorite are blow torches there's few of them in that pictures there's the orange hose at the back you see it better in here and i i make jewelry when i have the time um the big blue thing on the left is one of my latest acquisition it is a running mill for soft metals and as you can see i managed to break the if you can see can i highlight on the talk no uh i managed to break the cog uh it was a lovely lovely conversation with the chinese vendor to try and get a replacement cog sent over um as i said i have lots of tools i put

them on some but there's no point trying to write them all but tools are fit for purpose they make things easier um i as as it tends to be it's not just in it i end up collecting tools here in in my office some of the other toys i had i had to have access to this is my next-door neighbor lathe that he just recently got rid of because he clearing up his shed um and i am a member of the reading hackspace called and some of the machinery some of the equipments we have over there so i can share with you before we go into the output of things and everything will fall into an order

hopefully in two and a half minutes or so so that's the old 3d printer which was part of the riprap self replicating 3d printer it is a movement that's still going on strong but we now use couple of ultimakers which i couldn't take pictures of as they have written phone numbers which constitutes as pii and we have very very strict rules in there um this is the metal lathe i get to play with now and on the bottom right there is the laser cutter from the hackspace and on the left you can see a couple of the saws the bandsaw on the table saw um we have facilities to cast some metal or turn some wood

or work with steel to all sort of varieties of degrees so pretty much we're limited by our creativity which is what we are trying to what i am trying to talk about right so what so we have a lot of tools and it's all great fun so as i said i do a bit of silversmithing this is my lovely wife managed to convince me to get some stuff made for christmas fair so it was a few months intensive of hammering and melting metal but some things came out of it and you can see some of those pictures um that particular ring on the right is one of my first attempt with that cheap chip chip

cnc machine to do some celtic engraving it didn't come out very very good but for reference size the ring band itself is six millimeters so it's not the biggest of engraving of all and the ring on the bottom is kind of tend to be the style of jewelry that comes out it happened accidentally when i started teaching myself silversmithing and casting techniques and this is natural material casting which a lot of my things ends up looking along along those lines um i guess artist style not an artist i'm a techie so it's weird but i do that for fun i did that to relax and my wife absolutely loves my hobby so everything she doesn't manage to

find a new owner to she gets to keep and it's a win-win this is uh this was the last piece i've made it was done for friend's wife in the us she's from west virginia and wanted the state outlined the state flower and the university logo on a brooch and because it's a lot easier to define details when you have machines this is when the cnc and everything starts to fit back in into how does the workflow actually manifest so though i can trace the flower line by hand it's a lot easier to get the machine to drive it forward i'll stay on the slide for a second if you want to have a look

there's some more jewelry and some pictures on on that website my website um for your own entertainment right so since we're talking about the tools i think we pretty much covered what since what jewelry is like let's talk about stuff that comes out from a laser cutter so the laser is in the in our lab in the hack space and this is one of the first pieces i've made after spending mesmerizing hours looking at the machine moving left and right this is glue only my storage unit that if you put too many hard drives i can tell you the shelf falls down this is also been made in the hack space funny enough it was marked with the

laser the laser doesn't cut this thickness of material but it's a great marking tool in order for you to have guidelines to go and hit it with the saw so that's a collapsing table i kind of came up with and made probably a couple of years back it was due to necessities we needed to put something some laptops in in our spare room which is tiny as hell as you can tell um if i combine the the wood and the laser and maybe a bit of boring making holes not boring not entertaining and you know little pen holders with some quotes of wisdom or i made steve a knife on the old saw blade um the knife above i forged in

the in in the forge in the hackspace we have a forge so that started as a suspension spring and ended up being a knife i have made some monitors again i needed the casing very handy when you can cut things to some accurate measure use hot glue gun quite deliberately and put everything in place and you end up with your own custom monitors which is pretty cool as you can as you can see when you stack on your hp server that plays up it's quite handy to drag it along with you into the into the garage and see if it works game sorry i need to just do a quick time check so i won't delay anyone

um game controllers retro gaming we like to play so again i made another bigger monitor and i don't need two monitors what do i do with the sperm monitor and i've seen this arcade online for too many hundreds of pounds like seriously it's written driven by raspberry pi the electronic itself is like 15 20 pounds on any amazon alibaba whatever ebay whatever you'd like to shop at and we have uh we have an arcade machine um for those of you who goes to besides london and might have been a rookie in 2018 you might have got a box which i've made 22 of them brian helped gluing them all up on the day of the event for every

single one of the rookie speakers which is a great fun um and also for me as a little way to say thank you for all this rookies really really really never spoken before and feeling the hit this is one of my favorite things that i made in when gdpr came about just before gdpr was out uh it was a joke started as a joke i made one this is the top one on the right was done with the cnc as you can see the clean white engraving on it stay with the plastic and there was some demand so i end up making a hundred of those i have none of them left in my possession i mean i have the template i

can make some more but they were absolute success um if you have any put it please put it in the slack i would love to know about that um this is our table router in the hackspace where we were missing some inserts take it to the laser find some material in the right thickness and you make as many inserts as you want and again tools to make tools in order to improve the tools um and and as it is a creative aspect ultimately not just making tools this is lily my youngest daughter wanted the door sign my little ponies it was a hit back then i think it was the age of six so we have my little pony door sign

which is now off the door because we've grown up a bit the same with the teddy bear it's a felt that just design it in inscape i mean trace couple of circles and couple of squares around that but put all the dotting line for the thread through the laser machine so it's easy for little ones to sit down and entertain themselves a bit up to more some serious stuff for those who like a bit of steak um here is your own custom-made steak board that was etched in the laser done all in the hack space it's a nice piece of walnut route it out with the with the drain air tray and all that and

engraved in the laser machine being filled and then varnished treated actually oiled in this case because it's a cutting board and a lot of blood um made us a chopping board this is a butcher boat this is more of the hackspace facilities in terms of the planet the saws the the clamps which we'll touch about in a second there is a very clumpy picture in my slide um it it is a mini butcher's block because my wife cannot lift anything heavy with her wrists so we do like our meat and we do want to chop it i made a butcher book it was requirements and and the challenge of finding things that fits for purpose sometimes that drives

me to create things the same with this wood burner i can't turn the camera because it's quite fixed but this wood burner is my heat source in my office in that office workshop shed [Music] so moving the laser aside and going to 3d printing um a dust extractor from a cnc machine which failed miserably if i'm being honest but at least the process of finding designs adapting the designs to my specific machine needs and then understanding that the biggest failing point is the rubber hose from the hoover that waits a ton and the machine doesn't just cope with either the accuracy or the clump does not cope with holding the plastic in place 3d puzzles figurines lockpick holders

besides logos from last year which was made in 3d and printed out and was giving out to some of the people i absolutely love star wars i was showing it to sam yesterday we were playing with the blaster so you make your own um star war bits and bobs because hey you can it's great fun and it's it's relaxing to some extent this i can stand up for and i probably should take my virtual background but that was one hell of a printing job it is um seriously serious swords from the witcher game and let me just find out is my my screen is still shared excellent so let's find how do we take the virtual background off

sorry about the few seconds delay in the flow and hopefully on it i don't know if i'm streaming myself actually if you stream in the video but it's quite a sort of a significant length as you can see by the dyson for comparison which is 3d printed and reinforced with carbon fiber otherwise the parts falls off we 3d print wands or we turn them in the wood lathe it goes all the way to [Music] making lockpicks um tsa number seven open tsa number seven locks as you can tell or having a nice holder for a yellow lock because otherwise they really dig into the flesh when you hand hold them to try and pick them

i here's an introduction to bash he's a new family mascot but the picture on the bottom um all got really into her archery and she wanted a stabilizer for the bow during the pandemic the delivery time was super long on the archery shop i don't know why they're not amazon but it takes them a long time to send your parts over so by this time the shipping was processed and sent over i've taken three old arrows and made a few fittings with some weights to reproduce that counterweight she was looking in the balance and she's got now a proper piece of tool that does its job avidly so we talked about the cnc uh reductive

manufacturing which is probably my favorite type of tinkering with machines this is a lot of clamps as i said but i had an idea of making a speaker it is a 13 quid speakers module i think there were 15 watts from ebay and in the time it's taken them to arrive it was leftovers of mdf and plywood as you can see in the pictures that end up with a couple of very very functional sounding better than 13 quit and and looking all right as my office speakers um same thing since his crazy ideas i have two little nephews and i thought that a pencil driven cars when you can go and color them and take them with youtube

when you go to a restaurant and give you that pack of four pencils and the coloring that finish after 20 seconds can be nice so it's stackable you can run them as a separate car you can put all of them together and you can have a play um and i like playing and i like toys so as you can see the outcomes of things puzzles for the nephews pushing stumps pushing my merchandise don't make stamps i made some for my kids some diffuse is the company i have now the consultancy i have and i've done have a rock in 2020 and it's funny i missed completely missed the beer farmers uh freebie drumsticks but i've made that for my

clients as a beginning of the year to you know thank you for your business um which was quite a nice adventure to play with rotary controls on the cnc machine and a little bit of hackery because the controller the old controller didn't quite want to work and this is again um just going back to that don't buy that's really really really cheap cnc you might as well build your own it's not too complicated but if you look i think on the top and on the bottom of the picture it's very noticeable how the machine misses completely that straight line and taking 15 hour work this is the size of uh of a box of my small box of

matches um hotel matches kind of swatch thing and it's quite frustrating after such a long time to have the machines to fail on accuracy or quality of the work this is for lock picking set um there are a couple of repeating tools that i've made on the lathe with brass it was plus is probably the most fun material to work with when it comes to turning it flakes amazing like sparkly everywhere it's terrible if you have any pcbs around um should be a video here you can just see it flying there in the bottom it's like rain of brass it's absolutely magnificent i can watch it for hours on the machine not on the video um but

i've made a friend a friend's kid and a lock picking practice set so everything from starting to pick all the way to repeating and cutting away your own keys all in a little knit box so again i'm lucky i have a cnc machine i have access to all those kind of tools and like sometimes i have the time to actually or dedicate the time for it late at night to go and play with those things i like um as i said at the beginning for me it's very very important it's that level of balance a couple of other things that and i don't know why the bluetooth uh sniffer ended up being in here because it never got any closure at

the end it had i had a project in mind with the rfid the bluetooth and couple of other bits that never taken maybe i need to add it to my list of projects never taken off but on the left is a gps module that's supposed to give me a another source of ntp in order to balance time i don't care about positioning i don't care about satellite timing which means i need a very very low signal quality as long as i can triangulate once my time signal usually comes in flow right um other hackspace stuff painting painting my daughter's bike she's a harry potter fan she wanted the nimbus we made the i'm nimbus going to read you dr seuss

quote but i think it's important so i leave it here um i'm doing all right with time i believe so i have a couple of slides around resources and let's go through them reading hackspace art

it's

things a little bit easier i know i share my some of my things up there um i know a lot of people other people do i use kitronics for the rest of the material but saying the rest i use kitronic for the plastics mainly so perspex dual air vinyls things like that comes from kitronix really really really rarely the plywood laser as they tend to buy it in a bigger quantities at a better cost elsewhere reddit has phenomenal channels for makers based on whether material or whether it's based on the type of manufacturing you want to do whether it's cnc or 3d printing all the way down to a specific model of a tool with the subreddit there is wealth of

information day i mean youtube and reddit are your friends google will help you get there when it comes to software and a little bit of the workflow and it's not complete and i'm being honest it's ever evolving but the tool i use the most is the fusion 360. i use it for modifying cad files creating my cad files for the cnc for 3d printing for the laser engraver in escape might be my simplified workflow go to for creating simple dxfs that then i can go and manipulate them for cnc machining on a two and a half d kind of aspect rather than 3d machining didn't go too much into all the machining concepts i'm happy to go

deeper into that if anyone is really interesting ugs is the sender most people use basically most of the grbl based arduino controllers will spin up a serial port or the usb that will get the communication so that will be java-based pieces of code that will send the g-code which is coordinate system over to the serial target um i use brackets and atom as i use osx linux a lot so that will be my text editors gcode is basically just a pile of text i do run all the machinery from windows as it's quite prerequisite for some of the software operational software for the machines but they are in the process of migrating into being a bit more free so i can just

plug them any way i want rather than being limited by my old laptop that it's half dead um usb cnc usb is the controller that the knockoff controller that used to be in my machine that came from china or a knockoff of usb cnc um and octopi i spoke about that to a gentleman yesterday around the challenges of printing over the network but octopi is a raspberry pi distro designed for managing 3d printer over the network and manage all your print workflow all the way from slicing to printing with monitoring it through cameras and some really clever plugins some people like it i had mixed experiences without a lot of lower quality prints due to the

bandwidth of the [Music] of the data and the data band which you send the program through and it's kind of affecting the print quality in my opinion i have a list of things that i'm planning to still make happen um among them is building a safe tracking robot this is the next one on the list just because um this is some metal welding projects like the wood burner style i have some gargoyle-based um manufacturing going on i have i put a new fence in the garden so i want to put goggles on the post make them look nice and bash likes living in boxes i'm gonna make him a box to live in uh and with that and with time i will

thank you a lot i had a few slides and i was hoping might have time for questions and answers but since i managed to nail 90 odd slides in 30 minutes i am one of the happiest chaps today
