  • Conveniently framed
  • Log     from IoT RGB LED Matrix Controller (ESP32)
  • Recently, while moving and getting some furniture from IKEA, I found the perfect frame to host the RGB matrix, the RIBBA frame: The matrix is 190.5mm x 190.5mm x 14mm, the frame is 230mm x 230mm x 45mm, plenty of space for the matrix and the electronics....

  • Power protection
  • Log     from 200LX modules
  • Quick note on power rail protection. LTC4365 (pdf, digikey) seems nice little device for protecting things; it does under- and over-voltage, and reverse polarity protection. It is bit pricey though, but if that avoids setting things on fire then I think...

  • CNC Automation Demo
  • Log     from WEEDINATOR 2019
  • Another project milestone has been reached ….. The CNC mechanism is now automated and a few hundred lines of code written to perform a basic demonstration of all the servo motors running simultaneously. No special servo library is used, which makes coding...

  • Off the shelf
  • Log     from FoneTroll II: Gyro-mounted FPV/controller
  • For my proto, I am planning to go as 'off the shelf' as possible. A lot of my other designs have a lot of 3D printed parts, but this frame is going PVC... PVC:: 1 inch PVC pipe is awesome. Just, awesome. Things I have built with it include: - hammock...

  • single FPGA slice (without routing)
  • Log     from Silicon
  • I felt like building an FPGA slice, so I did.Based somewhat upon Nick's Blog entry here.Sorry for the bad photo, my phone has issues.  Essentially the bottom three ICs are 74hc595 (CMOS logic levels) for allowing an arduino to program...

  • Bench microscope based on a DSLR
  • Log     from Silly hardware wishlist
  • The lion kingdom inherited a lousy Amscope student microscope.  It's stereo, has good lighting, but an extremely small area to work in.  The lion kingdom also has a DSLR with 100mm macro lens.  That would have a much bigger working area,...

  • Frame Assembly Part 3
  • Log     from CNC in a box
  • I basically finished the assembly, although there are still some hard points that needs to be solved. The pieces for jointing are square but I missed my measurements in some area by a couple of mm. Making bigger bores for the screws seemed to make it...

  • An alternative to optical isolation
  • Log     from Isolated USB null modem
  • The project works as it's currently designed, but I was turned on to a different sort of isolation solution by a Twitter follower (I'm sorry, but I don't remember who as I type  this). It's the SI8035AA-B-IU, which is a 3 channel logic...

  • Crossfire Radio and HAM Licensing
  • Log     from Autonomous UAV w/Mavlink
  • Recently, I received the first part for this project, a Crossfire radio system (thank you ECE depot at the U of M!). This is a long range radio link with up and down telemetry. This radio, unlike normal RC links (2.4GHz), operates on 900MHz (@ up to...

  • New 3D Printed Case
  • Log     from All-In-One Gamma-Ray Spectrometer
  • If you want to get a case for the Open Gamma Detector, you can do so now! Finally, here's a 3D-printable case with a couple of different cover styles to mount the detector PCB and the scintillator. It's not really small, of course, but you can mount...

  • Y Axis
  • Log     from CNC Plasma Table
  • The Y axis linear guides do not use the plastic wheels of the original design. They now use rubber coated wheels. The wheels were made from a couple of rollers that were cut down. The ends were faced off to length in the lathe with a center hole opened...
