  • Standards of a sort
  • Log     from Twin Cities Maker
  • While the eclectic nature of our shop has a certain charm, several areas beg for a bit of standardization. So from now on all new cordless tools will be DeWalt 20v lithium, and all new shop vacs will be Ridgid 14gallons. Obviously interchangeability...

  • Initial Thoughts
  • Log     from Hubsan X4 Replacement Frame
  • As I mentioned in the description, I'm mostly looking to improve the motor mount system--I'm not a fan of two friction interfaces working against each other, especially when one can potentially cause damage to the motor leads. Last time I tried to pop...

  • Inspirations
  • Log     from Hubsan X4 Replacement Frame
  • This list is far from comprehensive, but these are a few existing projects:3D printed frame by xm_holgerAll-CFRP frame by rz_alexH-frame by RCaDDiCT!CFRP design by ridemtb473D printed frame by stu121Got another? Toss a link in the comments and I'll append...

  • MORE RADII!!
  • Log     from Hubsan X4 Replacement Frame
  • I haven't putzed about with the v0.1 base at all, but I think I've got a motor mount design that I like. It's got the split bolt setup for securing the motor (including a cutout for holding a 2-56 nut), and the legs are cool lofted dealies. Lots of radii...

  • Trust in Cyanoacrylate
  • Log     from Hubsan X4 Replacement Frame
  • Note to self: design-for-manufacture is NOT the same as design-for-assembly. Especially when DFM translates into "who cares, we're 3D printing it anyway, I'll just watch wall thickness and drain holes and be good to go". Mocking up the X4 frame proved...

  • Software, and hand-soldered prototype
  • Log     from Improve the Haber process
  • New board, 9000 lines of software, resistive load, drill-press frame.I managed to pick up a bug which slowed me down a little this week. Just wrote software and did a few minor tasks.Someone at my space works for Linear Technologies (!), and knows LTSpice...

  • Recap: early work #2
  • Log     from BradWii on the Hubsan Q4
  • After a few iterations of the OpenSCAD model and a week of waiting for the pogo pins I ordered from Sparkfun to come in, I have a working jig. It turns out my photogrammetry was a little off, since it took a couple of iterations of the model to dial...

  • Recap #3: Bringing up BradWii
  • Log     from BradWii on the Hubsan Q4
  • I spent a few lunch hours poking at BradWii. Usually the ARM fork of BradWii is built in Keil, but TheLastMutt had added project files for Eclipse and GCC. I don't care for Eclipse, but for a small project I'd deal with it. I couldn't get the OpenOCD...

  • Recap #4: Flying
  • Log     from BradWii on the Hubsan Q4
  • I ran into a couple of roadblocks in the week since barely getting Bradwii loaded:BradWii for X4 was configured to arm the motors if the yaw is all the way to the right and the throttle at 0. The stock TX has a range too narrow to hit the default thresholds....

  • Recap #5: Abusing the debug port
  • Log     from BradWii on the Hubsan Q4
  • So it turns out BradWii can do autotuning of the PID coefficients. It pitches and rolls +/- 15 degrees, systematically varying each coefficient until it converges. Once the tuning is done, the new coefficients can be saved to EEPROM. Autotune is started,...

  • Recap #6: Moving slowly
  • Log     from BradWii on the Hubsan Q4
  • I went a few rounds with PID autotuning in the living room after the kids were asleep. It's been constant nasty weather for the last few weeks, so I couldn't get outside so the Q4 could have more room for its autotuning dance.Meanwhile I discovered the...

  • SWAG CONFIRMED
  • Log     from Hackaday Prize Worldwide: Bangalore
  • This stuff will be at this meetup~!1. A Parallax Propeller project board with USB (The Parallax Propeller 1 is one of the first open-source micro-controllers)2. Odd-ball mix of blank PCB's - AmpHour/OSHPark SMD to DIP converter, Dangerous Prototypes...

  • 9/7/2015 Update
  • Log     from SAB3T - PID Loop Educational Tool
  • New PCB!One of the things on my to do at the 8/17 deadline was a new PCB design. My Previous PCB was just a breakout board for an Arduino Nano to make the connections easy. I wanted to create a dedicated SAB3T arduino compatible board. I based this design...

  • Another Try
  • Log     from CNC Mill
  • Based on what I learned with my first cnc I knew that I wanted something better. It had to be more rigid and more accurate. The size was not as big of deal as I once thought. My first cnc was 24"x24"x4", The x and y bed was bigger than I needed, but...
