  • January Update
  • Log     from Robotic Table Tennis Ball Machine
  • I received my power supply, motor speed controllers, and the CNC shield. I have gotten all of these to work properly and am starting to work on linking the two arduinos together. This is because there are not enough input and output pins on the CNC shield...

  • Lay up carbon fiber core.
  • Instructions     from N+ Open Bike Shoe Platform
  • Guide for making Core version 1I did a few layers, then placed the nubs in. It helps to poke the allen key through the bottom of the mold and through the weave, then chase it with the bolt. tighten the nubs securely into place, continue applying...

  • Presenting toeguard v2
  • Log     from N+ Open Bike Shoe Platform
  • Sorry for the lack of progress on the Diodedora project, I've been speaking to some 3D printer companies and trying to optimize the overall design of e platform to be more accessible for v2. I did manage to play a bit with the toe guard and came up with...

  • The Tank Chassis
  • Instructions     from WW2 Tank Laser Tag Game
  • DFRobot was generous enough to send me two of their MiniQ Robot chassis. The chassis have plenty of mounting holes that allow you to add brackets. They come with two motors and wheels, along with two sets of caster wheels to add strength. The assembly...

  • Better testing through Kossel
  • Log     from Multi-Material Hotend
  • Just a quick update: to better test this hotend design I decided I would have to build it into a real 3d printer. Unfortunately I don't have one I can cannibalize, so I had to go buy an extra one. Being cheap I bought an Anycubic...

  • Hotend testing framework
  • Log     from Multi-Material Hotend
  • With the AnyCubic's Kossel assembled, I'm replacing the standard hotend assembly with a 3d printed carrier designed to accept the high-temp resin hotend. You can see the frame here: The hotend will slot into place and be secure with the fan bolts. I...

  • Modular LIon Battery Charger
  • Details     from Modular LIon Battery Charger
  • I 3D printed a "holster" that can hold a single LIon cell or 2 that are soldered in parallel.  That seems to be a pretty common configuration in laptop batteries. Then I purchased a set of battery contacts from Amazon and some common LIon charger...

  • PCB Rev 0 sent to manufacture, and other good news
  • Log     from GLOVER
  • The full Rev 0 PCB Design is complete and gerbers have been sent to the manufacturer! We are manufacturing 3 prototype boards from the amazing OSHpark. It's a 2-layer board with all the components on one side. And below is the 3D render for your viewing...

  • Making more!
  • Log     from Optical motion capture system
  • As I've mentioned previously, this type of mocap system requires multiple cameras. You need at least 2 cameras to see a marker for 3D triangulation to be possible. When capturing a human there is a high chance markers will be obscured, requiring at least...

  • Guesstimating LED drive current
  • Log     from Low power IR beacon
  • Let's see how much current can we put through the LED and still make the 1 year battery life goal. From the last log we have around 31ms of MCU activity time and 1.5ms of LED-on time. We also have around 180mAh of battery capacity left for transmitting...

  • PWM to the rescue
  • Log     from Mushroom on wheels
  • I had tried to use PWM at first but I couldn't get the desired result, not sure why, but now it works... a little. The code has been updatedIt allows me to have smoother acceleration and braking so the mushroom doesn't always topple over, but I'm still...
