  • Some problems and limitations
  • Log     from PCB mill for under $10
  • Although this mill has produced some good results, it has also made some garbage. It would be naive of me to expect this mix of dumpster parts to perform as well or reliably as a proper mill. I don't want to make this sound too discouraging, but I'll...

  • Not quite dead
  • Log     from Hexapod
  • So after over three years I thought maybe I should post a bit more information about what went wrong with this project, what worked, and where things currently stand. First, all of the parts worked as advertised after assembly. I wired up all power...

  • Ordering parts from McMaster Carr
  • Log     from BuildLog Laser 2.x build
  • I choose to do the packs, since it is all useful bits and pieces and no matter how many of those darn pack of nuts, bolts screws, etc i buy from HF etc i never have the right ones.  These quantities are for individual part quantities, and not boxes....

  • HydraNFC Firmware is coming
  • Log     from HydraNFC Shield v1
  • HydraNFC Hardware: Schematic in PDF and CADSOFT Eagle 6.x design (CC BY NC) will be available (HydraNFC github) at same time as HydraBus will be in shop.HydraNFC Firmware (requires HydraBus) with VT100 and Autonomous mode (requires only power through...

  • HydraNFC board, BOM and doc available on github
  • Log     from HydraNFC Shield v1
  • HydraNFC GitHub Repository: HydraNFC_1_1_Rev1: HydraNFC Shield Schematic and Board CadSoft Eagle 6.x HydraNFC_Antenna_1_0_Rev0: HydraNFC Antenna Schematic and Board CadSoft Eagle 6.x All those boards and BOM are now available on github: https://github.com/bvernoux/hydranfc/tree/master/hardware...

  • 7-Segment Controller Board PCB
  • Log     from Open Source DSKY
  • yI finally bit the bullet after verifying me design and went and ordered them from Oshpark. The reason why it took so long is because is because it costs me $80 per board (Display Driver, 7 Segment Display), and then $40 for the micro controller Board....

  • Finally Acrylic is in hand
  • Log     from PixelWand
  • I stopped by Tap Plastic to get some Acrylic.  I bought 4ft x 4ft piece cut in half so that I can fit it into my laser cutter.  I have time scheduled on Tuesday to use the cutter, so I'm ready.Since I still had a couple of the test pieces left,...

  • Frame Assembled!
  • Log     from Simple DIY laser cutter
  • Well the design worked pretty flawlessly.  The frame bolted together quickly and easily and is just waiting on the OpenRail to arrive to finalise the frame.  I will still need to undo a few sections to attach brackets and bearing blocks but...

  • A small design change.
  • Log     from Simple DIY laser cutter
  • I have decided to flip the X axis stepper on top on the X axis.  The reasons for this are I cut out needing 2 idler pulleys and the motor mount can be simplified meaning both motor mounts are the same!  Although I lose a little X axis...

  • GT2 Belt clamp design.
  • Log     from Simple DIY laser cutter
  • I finally got around to designing the belt clamps that will attach to the bottom of my X axis gantry plates.  This is a simple design and will only require 2 screws to keep the belts tight and in place.I will be machining these out of HDPE.

  • Two-core Fluxgate
  • Log     from DC Current Transformer
  • My last project entry described a single-core fluxgate, and showed that it can measure primary currents. It also showed that the fluxgate injects a few hundred mV of ripple into the primary circuit. This entry describes a two-core fluxgate which offers...

  • Pulse Generation Circuits
  • Log     from DC Current Transformer
  • In the last posts we saw how a fluxgate works in simulation.  Simulations are all good when you can just add a pulsed voltage source - everything is perfect.  In the real world, we have some challenges:1) We need very low DC offset to avoid...

  • YM2149 Sound via FPGA
  • Log     from HD6309 Singleboard Computer
  • I recieved my hd6309 SBC bridge PCB right around Easter time. This is just a small PCB that interfaces to the expansion connector on the SBC. It brings the address, data, control lines through 5V to 3.3V level shifters (74LCX541 and 74LCX245 do the work...

  • Testet the X Axis
  • Log     from Homemade PCB-Mill / Laseretcher
  • First Test of the X-axis was succesfull. The axis don't have a belt at the moment, because they didn't arrived at time, but a sholace will works fine ; ). Next step is to Design the new holder for the y-axis linear shafts, with a included beltholder....
