Finally all the PCB's in one place
Log from LayerOne 2014 Conference Badge
left side, LF antenna, middle HF antenna, right badge board, top combined HF/LF antenna.The late nights/early mornings have started. The HF antenna is marginal right now so we just need to get the right caps/inductors added, but it did read. The LF of...

Post LayerOne
Log from LayerOne 2014 Conference Badge
Well layerone has been and gone, and apparently it was great, i don't know since i was in the back room getting a couple of hours sleep coding, while the others around me soldered boards together. I'm usually one to write up logs as they happen or just...

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...

Updated Flash Memory Choice
Log from Arduino-Compatible FPGA Shield
Realizing I've got heaps of room on this board, I've gone ahead and tweaked my choice of Flash memory. In this case, I'm still doing SPI programming of the FPGA, though using a Spansion part (at least for prototypes...I'll try and cost this down...

Introduction and Overview Video Posted
Log from Arduino-Compatible FPGA Shield
As the project unfolds, I've planned to produce some content - could be a video, could be a doc - that details the process I'm going thru. The first video in that series is posted now on YouTube and available for viewing at: This video really...

Video # 2 Posted - Wiring the FPGA for Flash
Log from Arduino-Compatible FPGA Shield
Completed the first part of the FPGA wiring for Master Serial / SPI mode - i.e. configuring the FPGA from SPI flash. Created a video that details some of the nuances and aims to explain the wiring in the schematic a bit. Files uploaded to...
