August 2021 - Reactor Upgrade!
Log from The Metabolizer
[UPDATE 10/21/2021 -After 2018 I started posting my updates on my Patreon page, and so I'm filling in the back-logs for this project retroactively so the whole story is in both places. You can also read all of these posts with their original photo...

Forward planning
Log from Quadruped robot with 22 DoF
Path generation and followingThe current walking gait system is mostly just a test of the kinematics and user inputs. To make the robot truly manoeuvrable, it requires sensors and better foot positioning techniques. The following diagrams are my initial...

3. Ruminations on the SQ6 and Parallax
Log from Instax SQ6 Lens Transplant
Parallax is the bane of point-and-shoot cameras, particularly ones with a lot of separation between the lens and the viewfinder. This is the case with the SQ6, which has numerous moving lens and film processing parts separating the objective and viewing...

Headband Construction
Log from Ariadne Headband
Once we finished testing our circuit in breadboard it was time to make it more solid. We considered few options how to connect modules and other components together, namely connecting modules with wires and leave them sort of loose in the box but because...

Low-cost and precise rotary encoder with magnetic spheres
Log from cyclabile
From https://ao2.it/135 You know what they say that constraints drive creativity, I think this post is just another little example of that. Usually I do not put time constraints to my hobby projects, but I make sure to have some other kind of constraints,...

Final thoughts on a collapsible UV resin curing lamp
Log from Collapsible UV LED Lamp + Resin Oven
Design goals portablecompactversatilityaccessibility of partsease of construction Each of the lamps created in this material research process is also completely portable with the help of easy to find 12v and 5v batteries that have been coupled...

Initial Work and Reducing lashing in leg/hip
Log from TipTap
Initial Work: Log update: 01/05/2019 As a first step I built a Port-Hamiltonian simulation framework in MATLAB, in order to teach myself the low-level math/physics. It turned out to be extremely slow, and so I could only use it for 2D sims. Here is my...

Evolution of a Spool Holder
Log from Wire Spool Holder With Straightener
Now that I’m warmed up to make circuit sculptures, it’s time for more practice. And for that practice, I’ll need wire and lots of it. Most of the projects I’ve seen are built from straight rods of brass that I could procure from the local...

First steering test deemed tentative sucess
Log from Landbeest walking robot
I've now built and tested the LB-101 prototype. I spent very little time on this one, and took a lot of design shortcuts. Mainly I wanted a practical test of turning by means of articulated steering. I also wanted to find out if this steering...

First PCB Working
Log from DrumKid: aleatoric drum machine
It's alive!Ordered 10 PCBs from JLCPCB, which arrived while I was on holiday. They didn't seem to suffer from the postman having left them under the bench behind my house in rainy England for several days. I ordered a few remaining components and soldered...

Testing Altitude Proof of Concept
Log from Water Bottle Rocket Science Kit
Last weekend, I decided to build a simple proof of concept that: Measured the altitude of a rocket at launchSend the peak altitude to a iOS device via BluetoothRecorde altitude versus time (for later use in calculating velocity and acceleration) The...

First project thoughts
Log from CircuitMega: Ultimate desktop PCB manufacturing
Every project starts with a personal frustration When designing and building my previous product, a device that attached to a smartphone turned it into a retro gaming console, I encountered many difficulties when designing hardware. As a newbie (I am...

Design For Manufacturing (DFM) Starts From Day 1
Log from BikeOn
DFM is one of the most critical parts of any project, if you are aiming to mass manufacture the device eventually. The typical route usually is to build a prototype which looks like the future product (“looks like prototype”), then...

Acid Test
Log from Careless WSPR
Summary The project was tested against a 'real' radio and digital interface into a PC running the WSJT-X software. It was verified to have modulated the WSPR signals correctly. Deets We're veritably at the end-of-the-road of implementing software...

Motor speed control
Log from Build your own TurtleBot 3 backbone
Wheel speed estimation Each hall encoder produces nb_{rising edges} logical rising edges per motor rotation (due to multiple magnetization points on encoder ring). Speed estimation relies on counting the number of logical rising edges nb_{encoder ticks}...
