  • It is done
  • Log     from Modular Pi Cam
  • Ahh man, 10 hrs later the decision to print with the front up ended up being bad... it looks good but it broke the seal/makes it look bad... oh well. Still... I am pretty pleased with it, it's bulky and it has a tripod attachment, large screen. Ugh......

  • First Solution Ideas
  • Log     from Automated Rabbit Hutch Door
  • There are several possibilities to detect if the rabbits are in or still out. The cheapest solution would be a light barrier but I doubt it woulb be light barriergesture sensorspresence sensorsimage recognition I doubt that 1. would reliably work, even...

  • Decision on the Sensors
  • Log     from Automated Rabbit Hutch Door
  • As mentioned in the last log, Thermopile matrix sensors sound like a very promising idea so did a short search wich ones would be available (see table below). But the would require at least some kind of image recognition which makes them complex to use....

  • Pulse counting interrupt

  • Log     from Battery powered LED pulse counter
  • The ESP32 has an pulse counting peripheral which would ideal for counting the LED pulses on a electricity meter, unfortunately it does not operate in deep sleep so will consume to much energy to allow for a decent battery life.Instead I plan to configure...

  • Pulse counting (part 2)
  • Log     from Battery powered LED pulse counter
  • After testing if the ESP32-C3 could wake from a rising edge GPIO, it does not seem to work. The datasheet was a bit ambiguous, but after writing the RTC_CNTL_GPIO_WAKEUP_REG for edge trigger the MCU would not wake when a signal was applied to the GPIO...

  • PCB Bringup
  • Log     from Battery powered LED pulse counter
  • I received the PCBs from JLCPCB which look great, however I have found some issues with the board: The TPS61023 boost converter IC I selected will operate down to 0.5V input, but I managed to overlook the point where it states that it requires 1.8V...

  • ROM disassembling
  • Log     from HP437B power meter teardown
  • I installed this disassembler: https://github.com/Arakula/f9dasm and had a first go at disassembling.It is a pretty powerful tool.Much of the ROM seems to be arrays of words, making me wonder if there if they used some kind of FORTH interpreter to get...

  • log II
  • Log     from home mri and fmri photo is AI production
  • version I what i made have 1X200 sensors. sensors have just stripes of metal  Fe80Ni20 alloy sensors have contacted to that way ++/-- that makes magnetic waves make higher to high points and lower to low points of waves and noise just stay...

  • log I

  • Log     from home mri and fmri photo is AI production
  • my first version of that log just get lost MRI first version have both max 0,5Tm two pairs coils i use Maxwell and Helmholtz coils what use to solve some problems to magnetic field Helmholtz and Maxwell coils have coil turns Helmholtz coils turns...

  • expansion log II
  • Log     from home mri and fmri photo is AI production
  • I most time make log when I have less time I add some details what I don t say last time first thing sensor massive dont have one output there has 10 outputs new version must be 100 outputs new sensor I think made of film and have some micrometres layers...

  • Laser marking test
  • Log     from Claymore - SLS 3D printer using polymer clay
  • Kinematic systemRecently (early March 2024), I built the kinematic system to move the laser head and the print bed.The laser moves in X (left-right) axis, and the bed moves in Y (forward-backward) and Z (up-down) axis.All the axes are driven by cheap...

  • DHT22 Wireing
  • Log     from GreenGuard: The Smart Plant Environment Monitor
  • DHT22 Sensor: The ESP8266 in the diagram is mounted on a breadboard for easy connection and may be programmed to send the data it gathers from the DHT22 to the Raspberry Pi or directly to the cloud for monitoring.It is powered through a micro USB connection,...
