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...

timelapse of power and arm/fpga soldering up
Log from LayerOne 2014 Conference Badge
we did a timelapse of arko hand assembling the first couple of rev3 boards since we can't pick and place them and test as we go along.

added a larger OLED
Log from LayerOne 2014 Conference Badge
Terrible cell phone pic, the 1.3" 128x96 OLED SSD1306 is a direct drop in replacement for the 0.96". Though it is $5.00 vs $2.57 , I do like the bigger display . I'll hopefully take a better pic of it, certainly couldn't take a worse one....

LF Antennas arrived from PCB house
Log from LayerOne 2014 Conference Badge
Just took them out of the box, need to test them and see if they've worked, RF is black magic.The other boards are also out for manufacturing. They should be here this week , hopefully since we have to pre-build a bunch!

anticipation, neoden, parts ordering, BOM.
Log from LayerOne 2014 Conference Badge
we're still waiting on a tracking number for the PCB's, the conference is in just over a week! and i can't finish the code til we get the first one made... oddly enough this hasn't been the closest we've cut it, but its getting there.since there...

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...

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....
