I enjoy building things. My first building blocks were Lego bricks. Over the years, the bricks have become more advanced, my budget and toolbox have grown, but the process remains the same.
You get inspired by "something," you have an idea, and you try to build it. Success isn't always guaranteed, but the process is always relaxing and results in some form of learning. Even as an adult.
The more you create, the more building blocks you generate, and the faster you can create new things.

Building a Mini Pi5 Cyberdeck Running Kali Linux
For this cyberdeck build I am using a NOS (New Old Stock) enclosure from 1953 (Suckle Electronics. made for the U.S. Army Signal Corp to hold spare parts)
The panels that hold the HDMI and keyboard is made from FR4 circuit boards.
It's a pretty standard build, but the vintage enclosure adds quite a bit of flair :)
Inside, there is a 8 Gb Raspberry Pi 5, a Pimorini NVMe base (that holds a 500Gb NVMe SSD). I'm using an actively cooled aluminium heatsink on the Pi, but I have also added a secondary 30mm fan for venting the metal enclosure.
The monitor is a standard 7" USB powered HDMI screen.
The dimensions are 26 x 12 x 7 cm.

I was lucky enough to be able to get hold of some vintage (probably 50s ?) and really cool looking metal carrying cases at an online auction a couple of months ago. I'm not 100% sure what their original purpose was, but I'm guessing they were used for carrying some form of breathing equipment. Since I'm currently building a couple of3D printed hexapod robots that I am planning to display at our...
Hexapod Robot Kinematics - part 5 (massive update and demo)
Просмотров 2593 месяца назад
My hexapod simulator is slowly evolving into something more like hexapod design studio. It now supports an arbitary number of legs and three different gait patterns. The legs no longer have to be anchored symmetrically around the robot body, but can have individual offsets and orientation. The length of the coxa, femur and tibia segments can now vary between legs, enabling more interesting crea...

Original Odhner 227 Teardown
Просмотров 5398 месяцев назад
My Original Odhner pinwheel calculator was a dumpster find some 40ish years ago. It was covered in some form of sticky residue, so it had to be cleaned up. Except for the sticky mess that covered parts of the outside, there was nothing wrong with it. I cleaned it up and it has been sitting on the shelf as a display piece for several years now. Some time ago, I wanted to demonstrate the mechanis...

This is a 3D printed version Spacebobs Battle Droid. It stands 1.93m tall and weighs in at approx 14 kg. The entire droid is printed on a 400x400x400 RatRig VCore 3d printer with a 0.6mm nozzle, using 0.2mm layer height. I used UV resin to get rid of any layer lines, The base coat colour is "Sahara Beige" (Montana Gold). Weathering was done using watered down acrylics.
Genco "Baby" flipperless electromechanical pinball restoration
Просмотров 905Год назад
I found this pinball in a storage area at Work-Work (barcade / co-working space in Trondheim. work-work.no/). The machine seemed to be a total wreck, but most of the parts were there, so I asked the bar manager if I could take a look at it and maybe try to bring it back to life. I haven't been able to find any pictures of this machine on the internet, so I hope this will be of interest to any G...

These are my two replicas of the XBOT 4000, from the Netflix show "Love Death Robots". The face was sculpted in Monster Clay and cast in two versions from a brush on silicone mold. The static version has a simple lidar and and will trigger lights sound samples when someone passes by the robot. The face tracking animatronic version is running custom firmware on an OpenCM 9.04 controller. This co...

Mostly Harmless vs Ascend in the free-for-all fight
Great! Aiming to build one too!
Hi! you are doing great job! i'm glad to see what are you doing, if you want we can collaborate with each other and appear in joint video, what do you think of this suggestion let me know
que bateria utilizaste??
You can use any powerbank that a) will fit inside and b) can deliver 5A of power or c) power it via the USBC socket next to the keyboard
Top😊
Lol
Nobody builds them quite like Tessier-Ashpool.
Those jetson boards are sadly pricey. Is a pi 4 the best low budget alternative? (pi 5 is too pricey also)

No Comment’s - Great 👍 Job ….. Hi 👋 from RTC “Kompozit” ….. Moscow City 🌆 ….. Russia 🇷🇺 …..
В этом видео стильно все!
kali with pi-cool😁
My man I have no idea how you figured this out but thank you!!!
I just peeked inside the SD card slot and then i thought "hmm..." :)
Excellent build
Can we get an update on this project? :) Looks super intriguing
The inspiration for this project was just the idea of having a set of “robot eyes” trying to make eye contact with you. I already had the Jetson from a previous project, so I decided to use that, but you could most likely get away with using OpenCV to do face detection. My inspiration for the eye mechanism was the eye mech designed by @WillCogley. Since I was using different servos and also wanted individual eyelid control, I had to do the design from scratch in Fusion (he only provided STL files, which are notoriously hard to convert to solid models for modification). I really just wanted to satisfy my own curiosity with this project and didn’t have any commercial aspirations, so the masks/faces are now hanging on the wall in the man cave. It was a really fun build, and it also gave me an opportunity to play around with mold making and rotocasting teqniques, using the excellent materials sold by @smoothon
now that makes me wanna build a mini pc
I love this trend, I'm in.
👍
Cool
❤
hey cool stuff!
Need advice with a problem with odhner 39 revolution counter reset handle jammed and not able to turn it can only be made to work and freed up by replacing zeros with any number on all wheels except the outside two at either end, have tried retiming with no luck any one any ideas please
Thanks bro. This worked perfectly. My adapter was faulty. Changed the adapter and the card was detected right away.
Really that's like a $400 head, a jetson really, wow, a pi4 is like $70
I already had most of the electronics from previous projects, so the financial "investment" in these heads was really only the batch of silicone, monster clay and resin. The Jetson was probably overkill, but it was a fun project and it gave me an excuse to play with machine learning (You could in all likelyhood get away with using a pi + opencv for doing the same thing.)
How did you develop the app for PID tuning?, like did you use Android Studio or MIT App Inventor for App building, because I woudl like to develop my own app for PID tuning and I need a starting point
It is not an app, only a web page hosted by the ESP32 that allows you to change the PID parameters on the robot. You can find the source code here: github.com/hansj66/automaton-xl320/tree/main/firmware/esp/balance-bot
I bought a 8mm to digital film converter with this same exact issue!! The tape method worked!!
Nice :)
Wow, good job! I'm impressed
Thanks!
Thanks for the cool video, I will look forward to more
Thanks for watching!
will this be the bite of 27?
Wow that worked, Thank you
Sweet build!
How do I participate in this project?
I'll upload everything to github once I'm done. I also tro to maintain a build log at hackaday.io (hackaday.io/project/195749-npod-controller-board-and-simulator)
awesome
Entertaining intro, but I'm not sure if your audience or demographic consists solely of Senior Engineers. So, If I may change it up a bit... [please explain the math to me as if I were a toddler]. 10/10 overall ;)
Thanks :) It is still a work in progress (I'm currently working on integrating servo control into the project. After that I guess I'll add a simple web server with a control interface . I plan to make the code and documentation available on github when I'm done.
Great work, great overall, underrated channel! Love the music at the end demonstration!
Thank you very much!
Wait, is he really a human, or just a human made out of ribbons?
And... it works! But how do you even think about such a thing as the memory card thickness as beeing a potential issue? By the way: thanks a lot!
The error was driving me crazy. This was a brand new camera and the error didn't occur until I had used it for a couple of weeks. If it was firmware related, it should have acting up since day one and also been more consistent. I decided to peek inside the SD card slot and noticed the mechanical microswitch inside. That got me thinking and I decided to test with a piece of tape to force the switch in case it was a mechanical issue.
Great job bringing this game back to life! Plunger housing looks really good! Is the score working correctly? Looks like it’s going from 900 to 1100, skipping 1000.
Thanks :) I didn't do any modifications on any switches. Maybe the scoring behaviour was caused by bouncing contacts ?
+1, where can we get this PCB?
I have uploaded Eagle files and schematics to github.com/hansj66/NixieKit. PS. I would not recommend trying the IN-1 variant of the board since it assumes that all IN-1 tubes have a precise orientation of the digits relative to the sockets (they don't...).
@@TimeExpandernot sure what the IN-1 remark means but thanks. Controlable ":" seperators like other designs would be a nice addition also. 00:00:00 For example. 🤷♂️
@@KJPage I made three different boards. for IN-12 tubes, IN-1 tubes and a generic board with screwterminals. Identical electronics&firmware for all boards, but the IN-1 and IN-12 boards have dedicated tube footprints (and you cant trust the digit to line up perfectly with the footprint for IN-1 tubes)
yup!!! THIS IS THE ONLY THING THAT WORKED! BLESS U
Hello friend. I m doing what you are doing but my 3d design a wheel rim after i convert missing the center. You know how i can fix that?
How did you un-jam the result register clearing crank? I have the same problem. The crank won’t pull out allowing it to rotate.
Since the channel seem unable to respond I ask, have you dissembled the machine following the video?
Sorry for not getting back to you. All the cranks were jammed. I suspect that the machine had been oiled at some point and that the oil had hardened. I manage to un-jam the cranks by adding _more_ oil and carefully pulling/pushing the lever. To my surprise, that resolved the issue.
@@TimeExpander What type of oil did you use? And did you clean the old oil somehow?
@@davidcarlsson1396 Just ordinary sewing machine oil.Not really sure if these machines are supposed to be oiled or not in the first place.
@@TimeExpander Whether they should be oiled or not is an excellent question. I will the coming 3 years attempt to research this...
really nice work. May I suggest replacing the balls? They look rough and might damage your playfield.
Nice❤!
youre a life saver, this worked!
Thank you! Learned so much more in this video! i spent hours trying to find a solution to my STL file issues!
thank you - this also fixed the memory card locked error on the new model sony zv1 m2
