  • power....
  • Log     from LayerOne 2014 Conference Badge
  • Arko started putting the rev3 board together last night, we usually build the power section first and measure how it looks, make sure none of the power is shorted in the PCB ( it happens). This board has one always on regulator, its a 3.3V LDO  that...

  • fedex and wildfires
  • Log     from LayerOne 2014 Conference Badge
  • It's wildfire season, but Fedex managed to get our boards from Malaysia to us in good time, unfortunately there was a cock up in the ordering department and they shipped to the billing address, we'd left there about 15 minutes before they showed up with...

  • Badge PCB's Arrived
  • Log     from LayerOne 2014 Conference Badge
  • After delays, e-test errors, shipping problems, wild fires and 6 revisions. These completely untested hopefully 4 layer PCBs have arrived. I'm probably just being paranoid but they sure look like 2 layer.Also Arrow decided that I didn't want overnight...

  • First Steps
  • Log     from Analog CPU Gauge
  • My first steps were to get my hands on a motor. I started with the X27.168 motor, seen here. There are a couple of variants of these motors. The 168 motors have the pins exiting on the back of the motor, while the drive shaft exits on the front....

  • Prototypes ahoy

  • Log     from Analog CPU Gauge
  • With motors in hand, I built up a quick prototype. The X27 motors are designed to only move a small pointer. They draw so little current (under 20ma at 5v) that they can be driven by PIC and AVR micro pins directly. Soldering wires to the thin pins of...

  • Designing a PCB
  • Log     from Analog CPU Gauge
  • I designed my PCB in my favorite software - Diptrace. The motor footprint from switec's datasheet was missing a few key dimensions. It took a bit of measuring with a caliper and calculating hole sizes, but I was able to get all the dimensions correct...

  • Of Pointers, Pins, and Needles
  • Log     from Analog CPU Gauge
  • While the PCB's were being built, I turned my attention to the pointer issue. The switec motor's have a 1mm shaft. A good pointer has to be a press fit on the shaft, but not so tight that the mild steel motor shaft is bent while pressing the pointer...

  • Putting a Face on a Gauge
  • Log     from Analog CPU Gauge
  • With the PCB and parts finally back, and working pointers printed in safety orange, I started assembling. About 10 minutes of soldering later, the finished board looked greatNow I needed a face for my gauge. I broke out word for windows (I know,...

  • Talking to the PC
  • Log     from Analog CPU Gauge
  • Now with everything built and wired up to the Arduino, I had one last step. I needed to get my PC to share its processor utilization data with the Arduino. I figured I would be writing up some software in C# to do this, but found an even simpler way....

  • Next Steps...
  • Log     from Analog CPU Gauge
  • While I do have a working system, I still am not done with the project - I'd like to ditch the Arduino and use a PIC or AVR to drive the motor. I'd also like to get the entire assembly mounted in a more gauge like enclosure. Something that would look...

  • Preliminary BOM and rough costing
  • Log     from Arduino-Compatible FPGA Shield
  • Did a preliminary BOM today and selected a few key components, incl. the Spartan 6 variant I'd like to use and the SDRAM and Flash devices (may go with a BGA SP6 package with more IO...no risk yet to the design, regardless of what I choose).  All...

  • Setup git repo for project
  • Log     from Arduino-Compatible FPGA Shield
  • For those interested, I setup a working directory on git for this project (https://github.com/sfgit/FPGA_Arduino_Shield).  I've uploaded a few libraries today also for the FPs and a !very! generic PCB (just the imported board shape and some parts...
