Summary about 6:00 pm, Monday, January 21, 2019 Something has gone wrong, and my NodeMCU board may be bricked. I have spares, but I will fail to get the project done in one day, as I had hoped. Deets While fiddling with the commands and starting...
So this is my first log, I've been busy with work, and spending time with my SO. I've been able to get my prototypes I'm going to work on built, the main thing now is software. I'm going to start slow, just sending (hopefully it works) one whole file...
Right now the prototype suffers from two distinct problems. One is that there's some crosstalk of the LED rastering on the audio. That I believe I can solve by simply routing the audio line so that it doesn't cross under any of the raster lines. The...
Fast forward to the first week of July in 2019. I was off work for a week, so it was time to get busy.The only thing left to do at this point is basically start buzzing out the connections. This was a very painstaking process that took DAYS to perform. Basically,...
Here I quickly made a pinout diagram of Ameba Writer and connection to RTL8710 WiFi module for programming. For operation check, one LED is connected between GA4 (D4) and ground. Selecting RTL00 in the board selection is all what we need to set up. (after...
This is one of my longest running projects. The seed was planted in my head when I was a kid, watching all sorts of movies. Those guys could always walk over to their computer and call up a cool display of their house (castle, secret lair, whatever),...
Got the manufacturing test fixture designed, boards back and built. Now to write code. The test fixture will program code into the on-board micro (actually program two programs, the first used to find the micro's calibration value) and perform...
The main goal for V2 was making it battery powered which turned out to be extremely difficult. First, the PCB and case was expanded to make room for three AA batteries.Then I started replacing/adding a few components: RT9080-33GJ5 regulator due to its...
Andrew Menadue has created a PCB for a datapak-tool to read & write to Organiser datapaks. It features an on-board SD card reader, display and control buttons. The board uses a Raspberry Pi Pico for the datapak IO and includes a boost circuit to supply...
TL;DR: participated in hackathon, worked on Joe-mon, didn't expect to win, won '1517 Grant Prize'. https://www.facebook.com/hackillinois/posts/1360661100660096:0https://devpost.com/software/joe-monWell, this is old news considering HackIllinois was back...
I installed the modified UPS board, and 100F supercap, into my heating system. It did not go well. The UPS would power the Pi and peripherals the first time that it was plugged in, but it would not apply power after a disconnection. I found two major...
I cleared off enough room on the workbench to do some more testing on my spartan mini fpga board with the end goal of completing this handheld NES project. Of course to be truly portable, I didn't want to have to reprogram the NES core...
I figured for a first try, I'd use a $6 ADCMP606 CML-output comparator. It's not the fastest available, with leisurely 160 ps typical Tr/Tf, and 1.2 ns minimum pulse width. There are faster ones available, like the $70 HMC874, with 24 ps rise and 15...
Too. Much. Overkill. what started as a basic teensy++ 2.0 based cartridge reader/writer is now a full blown project with a nokia 5110 LCD display with rgb backlight, 3D printed, vintage looking case, pcb for an at90usb1286. At least in my head. Please....
