Towers of Hanoi won't fit easily
Log from Exploring the Science Fair Microcomputer Trainer
I spent a few hours trying to fit in the recursive version of Towers of Hanoi (e.g., see here: https://www.cs.cmu.edu/~cburch/survey/recurse/hanoiimpl.html): FUNCTION MoveTower(disk, source, dest, spare): IF disk == 0, THEN: move disk from source to...

ChatGPT 3.5 programs the Science Fair (in assembler)
Log from Exploring the Science Fair Microcomputer Trainer
Not entirely unexpected, and not entirely serious either, but nonetheless - impressive! While it mostly failed to translate its generated assembly code into machine language (It's not a good assembler), the delivered assembly code actually worked in...

Solving Towers of Hanoi recursively in 80 nibbles
Log from Exploring the Science Fair Microcomputer Trainer
As Michael mentioned, he somewhat nerd sniped me with the the idea of squeezing a Towers of Hanoi solver in not the Science Fair Microcomputer Trainer. As an avid fan of both the Gakken FX R-165 and the Science Fair Microcomputer Trainer, I could't let...

Dumping the TMS1100
Log from Exploring the Science Fair Microcomputer Trainer
This post details the approach that Sean Riddle and I took when dumping the code contained in the Science Fair Microcomputer Trainer (SFMT) back in 2015. This built on previous work by Kevin Horton (aka Kevtris). Although I'm writing this...

Not quite modular yet... sunk cost?
Log from Modular Pi Cam
Oh man... so I've been trying the wide angle camera and I'm just disappointed honestly... I guess what do I expect you know? You can't compare this to a real camera eg. Sony Alpha Nex-5n (APS-C camera from 14 yrs ago). I went ahead and ordered the standard...

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...

Soldering... getting closer
Log from Modular Pi Cam
The front plate takes almost 10 hours to print... so I'm waiting on that. I soldered all the parts together, tested the buttons all work Tested LCD This is my last day off so won't be able to take it out till next week Monday I will reprint the back...

The first one!
Log from Anwaar Amulet - The story so far
Project Log #1 Little sparks for a gift - sometime in 2019 I think. When I moved to colorado about 5 years ago I got a job in PCBA assembly. It sparked a lot of on and off the job learning about circuit boards and their manufacture. In another lifetime...

First Solution Ideas
Log from Automated Rabbit Hutch Door
There are several possibilities to detect if the rabbits are in or still out. The cheapest solution would be a light barrier but I doubt it woulb be light barriergesture sensorspresence sensorsimage recognition I doubt that 1. would reliably work, even...

Decision on the Sensors
Log from Automated Rabbit Hutch Door
As mentioned in the last log, Thermopile matrix sensors sound like a very promising idea so did a short search wich ones would be available (see table below). But the would require at least some kind of image recognition which makes them complex to use....

Pulse counting (part 2)
Log from Battery powered LED pulse counter
After testing if the ESP32-C3 could wake from a rising edge GPIO, it does not seem to work. The datasheet was a bit ambiguous, but after writing the RTC_CNTL_GPIO_WAKEUP_REG for edge trigger the MCU would not wake when a signal was applied to the GPIO...

Proof-of-concept experiment
Log from Claymore - SLS 3D printer using polymer clay
In the beginning of this year (Jan. 26), before building anything, I did a small experiment to confirm the most important idea of this project: hardening polymer clay with laser. Methods The materials are: Polymer clay: Fimo Soft (black)Laser: VoidMicro...

Flashback : Prework
Log from TI-57 Programmable Calculator Hardware Retrofit
The more I read about the TI-57, the more I wanted to fix mine. Of course, these are easily found on a-large-well-known-online-auction-site for modest prices - typically $40 or less. Like most hobby projects, my goals were entirely devoid of practicality. ...

Blue Pill Emulation
Log from TI-57 Programmable Calculator Hardware Retrofit
Another key part of ensuring that replacing the TI-57's TMC1500 "brain" is possible is to ensure that the MCU has enough throughput to emulate it. My initial assumption was that a 64MHz 32-bit ARM MCU should be more than up to the task of emulating a...

Driving the Display
Log from TI-57 Programmable Calculator Hardware Retrofit
The TI-57 has a multiplexed 12-digit common cathode LED display. The corresponding 8 segments of all 12 digits are connected together; sort of. It turns out that TI economized on IC package pins by ”doubling up” the decimal point segment...
