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...
Dyson V6 Setup and Running System Dyson handheld vacuum cleaners utilize high RPM brushless DC motors. Specifications indicate that some models can reach as high as 125000 RPM. I’ve disassembled DC56(V2), V6, and V10 models. Each has a brushless single-phase...
The gist of this unit is that you type text into a discrete 'file' and then you can edit and later transfer to a separate computer via the keyboard emulation. While whizzing through the code doing other things, various strings caught my eye, such...
This represents a complete OPCODE list with 14 Constants (int values) available and 10 Labels (byte values) available for creating subroutines. Constants were favored over Labels, but this is up for evaluation. NOP and HCF were both added to the official...
I might be missing a few connections yet which I'll correct as I come across them, but here is the pinout of the XC3S250E FPGA on the control board. Note that the SRAM and the Flash share an interface bus. Also note that the JTAG interface...
After the explorations with #YGREC-РЭС15-bis, I reached several limits and I decided to scale it down as much as possible. And this one will be implemented both with relays and VHDL, since the YGREC8 is a great replacement for Microchip's PICs....
Debugging Need to get this project working. One problem is that the Nano does not have enough pins. So I have used a Meduino (a Mega2560 Pro Mini). Here is the schematic: Here is the PCB: The ports (P1 & P2) match the TTA8 bus. A problem with the Meduino...
With the new harvest, I estimate that the perfect and maximal orbits under m=1M is around 100K. This starts to make quite a large .h file to include in the sieve generator. Not that it's such a concern but scalability, you know.... And embedding such...
