  • We get signal
  • Log     from Reverse-Engineering a low-cost USB CO₂ monitor
  • Indeed, immediately after running the Windows software in a VM with the device connected I was getting a live data log of the CO₂ concentration! This screenshot shows me breathing into the vicinity of the sensor:Ok, time to disconnect the device from...

  • TI-86 Logic Analysis

  • Log     from Vintage Z80 palmtop compy hackery (TI-86)
  • whelp... I managed to speed up the sampling rate dramatically... My signal is /supposed/ to toggle (or not) at 8us intervals... My original sampling code took 39T-States per sample, or at 6MHz 6.5us/sample... IF I understand the z80 right... The new...

  • TI-86 Logic Analyzer
  • Log     from Vintage Z80 palmtop compy hackery (TI-86)
  • Ok, so it's gnarly-dusty and that's not real sample-data, but here goes: That's two lines of sample-data, from the link-port, wrapping, to show as much as reasonably-viewable (1024x2 Samples visible). Presently, I think each sample (pixel) is around...

  • Iteration A4
  • Log     from 6-Axis Micro Manipulator
  • So after a few iterations of re-design to work with NEMA-8 sized stepper motors which whilst not the smallest available are the smallest in the sub $20 bracket. In this case $12ea. With the increased size comes the headach of deciding on an arrangment...

  • Debugging
  • Log     from 8 Bit TTA Interpreter
  • 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...

  • All boards received
  • Log     from NEDONAND homebrew computer
  • The rest of the boards just came:I think I will connect them together through wire-wrapped "motherboard" (lets call it "NEDONAND-10" ; )All of these NEDONAND components could be tested one by one using PIC microcontroller (connected to PC through RS-232)...

  • How ESP-NOW really works ?
  • Log     from Linux-ESPNOW
  • To implement the ESP-NOW Protocol, we first need to understand how it works in details. The datasheet doesn't say much on the really low level, especially on the acknowledgment behavior. To understand what ESP-NOW does, I use Wireshark with my PC Wifi...

  • Peak Performance
  • Log     from SpiroBoard Aeroponics pH / EC / Motor Controller
  • Below is a picture of a patch that gates the input to the ADC so that it is only looking at the value from the EC probe at the end of the square wave pulse, after the initial transient has settled out. It works really well, dutifully recording the voltage...
