  • The Re-Assemble
  • Log     from Invisible
  • I am wiser now. With the broken pieces re-cut, I know how to safely assemble the sculpture so that it won’t break. Back over a rug, we assembled the sculpture in half the time. This time around I am not taking any chances and I’m epoxy-ing each joint...

  • First one assembled
  • Log     from AutoResetRRR
  • The first device skips the 5V regulator, as I am testing it with a raspberry pi. Everything is red, even the LED. I began to test it for the raspberrry pi as this needs the additional python software required to shut-down the pi safely. I am thinking...

  • Power Schematic

  • Log     from Electric Longboard
  • My first concern with a 2-battery setup was how to safely enforce that only one battery be enabled at a time and absolutely no possibility of shorting power to ground. I didn't like any of the high-watt switches or relays out there. Well, there really...

  • Functional alpha
  • Log     from Internet of Trash
  • After a week of choosing and trying out the hardware, a fully functional prototype is laid out on my work desk. In its current configuration, it contains an Iteaduino (a convenient Arduino UNO clone capable of both 3.3v and 5v logic) with a sensor shield...

  • This is the end!
  • Log     from DIY electrically heated sauna
  • I'm very close to finishing, and I have used the sauna a few times already.But I'm not continuing this project, because I am going to move house!What's the biggest lesson that I have learned about building your own sauna?The most important thing to keep...

  • Progress
  • Log     from Nixie Jewelry
  • I discovered you can get C123 sized lithium-ion batteries, so at 3.7V they are enough to drive a K155ID1 and puts the voltage safely over the 3V minimum for my HV power supply. They only have 700mAh compared with 1500mAh of the non-rechargeable...

  • Software
  • Log     from Blinkenschild 2.0
  • We use the great library by hzeller to drive the HUB75 panels.Check it out here:  https://github.com/hzeller/rpi-rgb-led-matrix After wiring the Panels and soldering the levelshifter adapter board the thing was up and displaying demos in no...

  • Resistors
  • Log     from QGPIO
  • I should also mention how I chose the resistor values, since that is something that can be tuned to individual preference.  10k resistors for the LED current limiting is quite weak and the LEDs are only dimly lit.  That is by choice so I can...

  • Drone Pendulum Fallacy
  • Log     from The Ball-Drone Project MK II
  • In the previous project The Ball-Drone Project I was faced with the challenge of building a slightly different drone. Now I don't really come from the field of flight dynamics and still had to learn a lot. In principle, the first ball drone flew. Correct...

  • Termination voltage regulator
  • Log     from STEbus backplane
  • The bus termination circuit from the specification is simple but the 2.8V regulator must also sink current when required. Common voltage regulators are only designed to source current. Examination of a 5-slot backplane reveals a working circuit.Current...

  • Assembling the hardware
  • Log     from Real-time OS automatic watering system
  • Once I verified that my code works, I began assembling the project. The first step was to assemble the high-power component. Since the pump I'm using run on 110V AC, it's important that I isolate the high voltage terminal. I used an electrical enclosure...
