Tonight I gathered some reference/research material for this project. Fortunately, several others have done some really great work with this module, so here's credit to them: LTC3780 DatasheetBeyond Logic blog postTemplaro blog postGreat Scott videoJulien...
I'm going to create a stand-alone PSoC project to use the PSoC to read SD cards. I'm going to start with the hardware defines for this project (which should leave the Z80 hardware pins unmolested) and just not download code. For the software piece, I...
When entering a short test sequence on my remote this is what my receiver displays (a dot means an exact repetition of the previous packet):All on: 07 B0 F2 EA 35 90 01 B9 AC F9 .......................... 07 B0 F2 EA 35 90 00 B9 74 E0 .. Color red: 07...
Initially I thought the data stream from the camera board to the quadcopter controller was PPM. This signal is only active when the app is running and the on-screen controls are brought up. The quadcopter has to be power-cycled in order to be controlled...
Plascii Petsma by Cruzer/Camelot has one of the nicest looking plasma effects I've seen for the C64. Since he included the source code, I was able to port it to the Z80 and TMS9918. On top of the features in the original C64 version, I have...
The STM32 board was just a hair bigger than the PIC, but the biggest pieces are still the power switch, channel button, & battery. The plan is just to print an L enclosure which scotch tapes around the hot shoe & sticks up. The antenna will...
I've got the BIOS loading for Multi-boot Multicomp. It boots up to the Multi-boot prompt. > Available Commands: :ccxxxxiibbbbbb Load Intel-Hex file record Rxxxx Run from address xxxx Sddd System boot Iddd Init: Format directory Pddd[,xxxx] PutSys: write...
Reading this Japanese article on a kit sold in Japan to build a Z80-MCB, I realized the presence of a possible bug seeing this two images: As you can see, there is a Z80-MCB without any Virtual Disk or RTC attached and in the resulting screenshot the...
For quite some time I have been thinking about the possibility to using a laptop to run all the heavy OpenPlotter and OpenCPN stuff instead of using a Raspberry Pi. The performance of the RPi is... well it's usable but it's not a pleasant user experience....
Quite symbolically, this Saturday, on March 2, Kyiv will host the first Maker Faire Kyiv in a long time! The last one was in 2018.Where, in addition to uECG and uMyo, we’ll present our first project in collaboration with TURFPTAx The device working...

At the OHSummit, I was joined by Amber Cunningham, community manager of Tindie. While Hackaday and Tindie have the same overlords ruling over them, we can't really have Amber going around with a Hackaday logo on her badge, can we?...So I spent 15 minutes...
Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....
Ok, now it is kind of proven that binary CPLD (or FPGA) may implement ternary logic, but how we can integrate it with "true" ternary components, especially when CPLD is 3.3V and TRIMUXes are -5V and +5V? Answer is DG403 chips may do the job: Because...
Fortunately most of the NASA documents are available. They can be found on-line at https://www.ibiblio.org/apollo/Documents/ The following documents are what I leaned heavily on in gaining an understanding of how this computer...
