  • New fertilizer, pH meter disassembly, LED drivers

  • Log     from GrowInBox
  • Hi!I have a lot of school work to do this week, but I decided that some thing just need to happen today or as soon as possible. So I bought a new fertilizer.The old one - plant food - TNT Complex from hesi has a NPK of 323 which is ok for the vegetative...

  • Research Report
  • Log     from 2021 HDP Dream Team: EJA
  • At a high level, the problem area is known as abandoned, lost, or otherwise discarded fishing gear (ALDFG) retrieval. This fishing gear is known as ghost gear, and falls into the wider scope of marine debris. Ghost gear has a tremendous impact on nature:...

  • 20230212d -- LCD Display
  • Log     from ROM Disassembly - AlphaSmart Pro
  • The LCD is a 40x4 character display.  Judging by my friend [Eric]'s@EricHertz photos, this is not the common HD44780 device, but instead a Mitusbish M50530 I did find a datasheet for this device.  If it's not code compatible with the '44780,...

  • Debugging
  • Log     from Wolf
  • Started to debug the code. So far the SNES controller reading is fine, operating mode selection is fine, Left port driving is fine.For this project I have used variables to store the state of the input controls and for the output data to interface with...

  • Received the Boards - Debugging Entry 1
  • Log     from Aper-Oculus
  • The boards have finally arrived. The past 12 months have been a mixture of waiting for parts, software design for FPGA IP Cores (harder than expected) and communicating to a thankfully perceptive PCBWay for fixing possible part conflicts with my BOM....

  • Kria GTH Findings and MIPI CSI-2 Working
  • Log     from Aper-Oculus
  • Crazy cool finding for the Kria SOM: if you save the settings from simulation of another GTH capable Zynq MPSOC (Like say the ZCU104 or ZCU106), you can load the GTH on the Kria SOM with these settings via dynamic reconfiguration, and have it working...

  • 20230213b -- Memory
  • Log     from ROM Disassembly - AlphaSmart Pro
  • I find it vexing that I have not yet figured out the RAM banking scheme.  Some things:at reset, the peripheral configuration registers and internal RAM are mapped at 0000h.  They can be moved elsewhere, but are not.  The RAM at 40-ff is...

  • On I/O
  • Log     from KZ80
  • The biggest challenge right now is I/O into the system. I'd eventually like to support KeyboardLCDSerial / UART for attaching modems and other such thingsCompact flash driveA Counter/Timer Circuit (CTC) Last night, I realised I could use a handful of...

  • You can refactor hardware, right?
  • Log     from MC68000 Computer
  • I'm in the middle of a few free days right now, and I figured it's time to take a look at this project. Things aren't good. Let's go over what's wrong with it:It's not doneIt's not even close to being doneThe 'not being done' is mostly a result of using...

  • Final bits
  • Log     from Reflecting the sun into your home
  • Ok we need some way to detect how many rotations the shaft makes, a CPU board, and a Real Time Clock (RTC). We should have some Flash memory as well to store our data points.Photo-Interruptor CircuitAn easy way of detecting shaft rotation is by using...
