Moving up the ladder of abstraction
Log from Gigatron TTL microcomputer
This photo captures the inner application interpreter's first sign of life. Very early this morning, or late last night, the virtual CPU ran its first program. It calculated the largest 16-bit Fibonacci number to be 1011010100100000 and plotted that...

Finally, I have a microphone
Log from Feedbass! (microphone in loudspeaker)
So, all my attempts at deafening a microphone without full teardown had failed, so I went for full teardown. This is what I did: And to put the microphone back together, I turned a capsule from a nut and a bolt: So now I can easily take it apart and...

Project Log 66: DIY Linear Actuator.²
Log from DIY Mech/Exoskeleton suit.
Thursday, 27/07/2023, 10:48. Well, I will just post this here, but I will keep editing later (I can barely edit anymore because I already wrote so much stuff). Just because It would be of great help if someone were to give suggestions....

Welding
Log from Wire 3D Printer
I needed a few M3*40 screws, but unfortunately it was past 20:00 and the hardware store had closed. So I thought about making my own screws with the wire printer, which actually is just an advanced spot welder. The "screws" are made of stainless steel...

Printing Process
Log from 3D printed Bench Press - Prensa 3D impresa FCFM
First, each component is designed in the Fusion 360 software, using commercial bench presses as reference. That's also the case for the dimensions of our 3D printed bench press. One of the challenges of our design was to ensure smooth movement for the...

Breakthrough with some small sacrifices
Log from Emulated TMS9918A using RP2040/DVI
This is no less than the fourth revision of the PCB. It still uses Dr.VIP which is a standalone project and could be useful for many other projects that need a Pico with as many GPIO as possible and an HDMI socket on the board, although that idea...

How I design
Log from Electric Sonett: Old Car/New Tech
Designing for this project required many different approaches. Sometimes it was easy enough to take measurements, design the part in question and make it according to those dimensions. Other times it would be exceedingly difficult to measure all aspects...

Touched up bin2mif.py
Log from PDP-8 FPGA
I touched up the binary to MIF utility (bin2mif.py) to set the address to octal. That makes it easier to map to the PAL list file. The top of the MIF file now looks like: -- File: sievePlusLoaders.mif -- Generated by bin2mif.py -- DEPTH = 4096;...

CNC Mechanism Nearly Completed
Log from WEEDINATOR 2019
And just to remind ourselves of the build process:Strangely, it's actually looking very similar to the CAD design.Although the CNC build went quite smoothly, I did make one critical error by getting the Z axis ball screw out by 20 mm. It really has to...

Steve's board
Log from STEbus Z80 and FDC
Steve reported some problems with his board. The reset generator (IC9, SN74LS123, a dual monostable) was holding the reset lines to the FDD controller and Z80 low. It should reset the FDD controller first, then the Z80. Not having a spare to...

Another... camera
Log from Modular Pi Cam
So I've got 4 days starting today to make the next camera This one has the sliding lock mechanism to interchange the camera modules Still prototyping the sliding lock thing but can see on the right it supports most of the RPi camera boards, software...

Project Log
Log from STEbus 68B09E
2019-05-30 I'd been putting this project off for a while because it is very complicated to get fully working and I have no known-good firmware specifically for it. I considered porting a monitor but a BASIC interpreter would be more impressive. Grant...

The Use of Foam As a Mobility Control Agent for Conformance Improvement
Log from The Use of Foam As a Mobility Control Agent for Co
My project uses X-ray microfocus radiography to monitor the changing displacement patterns and saturations of Berea sandstone rock samples while undergoing water alternating gas injection coreflood experiments. Water alternating gas (WAG) injection...

Final PID Notes on Stock Setup
Log from Monoprice Select Mini Electro-Mechanical Upgrades
So, this is PID but not PID. It's the Shakespeare of PID. I don't really care if I'm being dramatic because the stock setup is weird. Yes, I'm new to 3D printing and though this hotend may be the 8th incarnation, but man, it really could be better.----------...
