  • First run of 2x2 LED boards
  • Log     from Colordance Circle
  • The finished project will have six 4x4 arrays of LEDs. Each array will consist of four 2x2 PCBs, arranged in a square. We have to make our own PCBs for this because we need each LED to be pretty bright. We couldn't find anything off-the-shelf that (1)...

  • The Reasoning
  • Log     from Yet Another STM32 Board (M0)
  • I love the Nucleo, Discovery, and Blue Pill boards, but I find most of them lacking as a reference design. The Nucleo boards have a built-in debugger, which is fantastic, but I found it difficult to go from ST's documented schematic to my own design....

  • Layouts and Modularity
  • Log     from Sonic Screwdriver
  • In trying to learn from my previous attempts, I think modularity, and outsourcing will make life easier; that is, if you don't have to make things harder, don't.In particular, this is in regard to custom PCBs. In the second attempt of the sonic screwdriver,...

  • Arm Power Supply Development
  • Log     from Mars Rover Project
  • The team has decided to showcase the efforts made in development of the arm power supply.  In simple terms, we would like to operate the stepper motors on the arm at 24V to be able to achieve the specific torques at the speeds we desire. ...

  • Log 3 : Board Assembly & Sound!
  • Log     from Accelerometer Contact Pickup
  • After finishing the layout for the schematic in the previous log, I ordered a few boards from OSHpark as well as a stencil from OSHstencil. I cheaped out and went for a polymide stencil. This was a terrible decision since it's so floppy and a stainless...

  • Selecting a suitable oven
  • Instructions     from Reflow Oven
  • I went with a cheap toaster oven with quartz tubes on the top and bottom. Heater rated power 1000W was sufficient due to the small volume of the oven. Front panel You may select an oven with similar front panel to avoid having to cut anything. The software...

  • My First PCB -Eric
  • Log     from Barnabas-Bot
  • Hey guys,Last time I checked in I was just getting my feet wet with KiCad. Since then I have finished creating the PCB layout to match the schematic and milled the PCB out using one of the othermills here at the design lab. That took a couple of tries...

  • CoinOp Badge
  • Details     from CoinOp Badge
  • The major components of this badge include an ATmega48 microcontroller that drives 18 red LEDs, 4 blue LEDs, takes input from 2 momentary push buttons, and is powered by a CR2032 coin cell. I wanted a fast-paced project that let me do everything, from...

  • CoinOp Badge Assembly
  • Log     from CoinOp Badge
  • This badge would have been impossible to assemble without a solder stencil. I've never used one before and the important lesson learned is that fine-pitched components need very small openings in the solder mask. This was about $45 (delivered) so I wasn't...

  • Fabrication hints
  • Instructions     from Flex PCB Solar Motorized Earring
  • The design uses a 4mm diameter motor.  They are commonly available, but without part numbers.  The one I use has 13 ohm resistance and is 10mm long.  A shorter one is available but has 36 ohm resistance and doesn’t seem to work as well...

  • Project updates
  • Log     from LoRaWAN Feather
  • Couple of project updates:Hackaday has officially closed the Take Flight with Feather contest, they have said that they will notify winners near the end of January, so I'll continue on working away at it.I'm still working on getting a useful demo up...

  • Board Fabrication
  • Log     from MeowCAD
  • PCB FabricationUltimately MeowCAD is meant to create boards. The real test is whether you can go from idea to full board.I've created two functioning boards with MeowCAD. Both have been designed completely in MeowCAD, schematics and PCBs, sent to OSHPark...

  • Sprockets
  • Log     from Modular Continuous Track System
  • Now that I am cranking out the treads at a much faster rate, I need to start looking into testing this design out. That means building a tracked robot. Because my goal is to test out the modularity of the system, I actually want to test out many different...
