"Decle" wrote the following interesting comment on my second Science Fair video: @decle • 7 hours ago The virtual machine and monitor within the SFMT code is implemented in about 1K (the other 1K of memory is used for the 6 built in games). It's really...
Jason joined the team! He reached out to me after my first YouTube video so that I could set the record straight and correct some inaccuracies, in particular, the release year of the Science Fair trainer. Jason pointed me to the original Radio Shack...
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...
@decle has joined us - great to have you on board, welcome! Check out his YouTube channel. He implemented Nybl - a Science Fair emulator using the original ROM that runs on the Intellivision, and also has developed a method of dumping a TMS...
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 #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...
I received the PCBs from JLCPCB which look great, however I have found some issues with the board: The TPS61023 boost converter IC I selected will operate down to 0.5V input, but I managed to overlook the point where it states that it requires 1.8V...
Fault label: "Numbers keep changing".2024-03-01Switched on, set dials to maximum. Leftt around 28.8V and drifiting, right around 32.88Dials set to minimum.Left side very slowly descends to 14.3 volts, terminals are at -0.424 volts.Right side slowly descends...
READ THIS:● Some of you guys on the community commented that the AC high voltage clearance is too low. YES, YOU ARE RIGHT! I usuall add copper plane to all my PCBs and that was a mistake made ina hurry. So even if you see a bad clearance in the...
Julia and I rushed over to TAP plastics, hoping to get our acrylic sheet before closing. On the car ride over, I opened my CD case and asked Julia, "is there any music thatyou'd like to hear?" "You just have old people music, right?'" she said. She wasn't...
Once we got back to my apartment, the fatigue began to set in. It had been a long day already, with nonstop running around. I asked Julia if she could wait for a few minutes while I rested. She was totally understanding and didn't give me...
Sometimes, when making your own devices on microcontrollers, there is a need to display huge amounts of information on a display and to use a bigger screen for ease of perception. Unfortunately, there are no ready-made and budget-friendly solutions for...
First of all, you should pay attention to the ROM used. The flash-ROM chip from an old computer motherboard has a finicky parallel interface where the address is written in two runs. This complicates the operating logic and increases access time. Additionally,...
