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,...

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...

Decoupling Schema Completed
Log from Arduino-Compatible FPGA Shield
FPGA decoupling can be tricky to sort out without some guidance. Thankfully, Xilinx provides a pretty comprehensive PCB Layout guide that has specific recommendations for decoupling schemas for the PCB, based on specific parts and pin counts. I...

Top Level added, breakout, PCB progress
Log from Arduino-Compatible FPGA Shield
Uploaded a heap of stuff to git. Working on video now. This includes two layers of top level documents that show sheet to sheet connectivity between SPI and the FPGA and also have the breakout for the FPGA IO and other various items. Added...

Updated PCB Routing - SRAM, JTAG
Log from Arduino-Compatible FPGA Shield
Had some fun tonight playing around with PCB routing. You can see in the PDF in git or the PCB file (you'll need altium to open it) that I'm all about "pretty". :) Still a fair bit to finalize the routing and design and such but moving...

Uploaded PDFs to Git - Small Mods
Log from Arduino-Compatible FPGA Shield
Made a cosmetic change the schematic (top level) and also uploaded PDFs to Git. One small change to PCB was required to get the cost down (increased via hole dia for QFN LDO from 2mm to 2.54mm...makes "low cost" standard mfg avail)

Overhaul to add LEDs, dip sw, improve useability
Log from Arduino-Compatible FPGA Shield
Made some updates to the design over the weekend to add LEDs, a nice dipswitch, make the silkscreen cleaner, clean up the pad arrays a bit and a lot more in the way of little cosmetic PCB tweaks. Overall some very important tweaks but in the grand...

More FPGA Boards Back & Working!
Log from Arduino-Compatible FPGA Shield
Whew! Last round of mods were huge because as you come to find out quickly, anytime you add a level translator to a board - much less two & much less 10 channels each - you end up having to reroute most of the PCB layout. And as though that wasn't enough,...

Uploaded new files to Github
Log from Arduino-Compatible FPGA Shield
Made a few minor cosmetic tweaks, did some stuff on the PCB to try and make the next pass easier to add more IO (something that's been asked for) and really dialed in the output generators and outputs directory. Overall a nice cleanup prior to the latest...

Hacklet #4 - PCB Tools and Wristwatches
Log from Hackaday.io Project
The Hackaday Prize is heating up! When we set up the prize, we expected to see some incredible entries, and you guys haven’t let us down. Projects like SatNOGS, which aims to create a global network of satellite ground stations, or OpenMV, a low-cost...

Hacklet #6 - Lasers
Log from Hackaday.io Project
This week’s Hacklet is all about lasers, which have been shining a monochromatic light for hackers since 1960. The first working laser was demonstrated by [Theodore Maiman], who was a hacker / maker himself, having learned circuits in his father’s home...

HACKLET 19 – HAM RADIO
Log from Hackaday.io Project
Amateur, or ham radio operators have always been hackers. For much of the early 1900′s, buying a radio was expensive or impossible. Hams would build their own rigs, learning electronics and radio theory along the way. Time moves on, but hams keep hacking....
