Progress report
Log from LiFePO4wered/Pi+
Time for another update! First of all: the question of Raspberry Pi 3 B+ compatibility! I have to admit I was nervous when I heard that the Raspberry Pi Foundation was going to announce a new product on 3/14. What if they announced something...

First Prototype Up and Running
Log from MeArm Raspberry Pi Edition
After getting my head down and working hard to get the redesigned MeArm mechanicals with the Raspberry Pi base up and running, we were pleased to be able to show a few people the working prototype at last weekend's Maker Faire in Rome. Here are the big...

Another integrated PoE option
Log from IoT Ethernet Sensor using Power over Ethernet
I'm currently working on my Raspberry Pi Windows 10 IoT solution which will use a 5" IPS capacitive touch display on top of the Pi and have a peripherals board which will host a RGB24 to HDMI converter TFP401, audio amp, ambient light sensor, LED, IR...

Finished board now available on Tindie!
Log from $5 Graphics Card For Homebrew Z80
Ok, thanks for the support from everyone that has followed this project. The goal of this project was to get a Raspberry Pi Zero working as a serial terminal on my RC2014 computer, and produce a PCB for this. Well, that has been achieved and this kit...

The development hardware
Log from GPS Receiver for Nikon D3100 Cameras
I added two photographs to the gallery which show the portion of my workbench where I am working on the hardware for this project. The second picture with just two small boxes in it show the GPS receiver package. The square object near the top right...

IR illumination & passive markers
Log from Optical motion capture system
The LED active markers are a very viable solution for motion capture, but I'd like to explore the alternative of using reflective passive markers. These markers are small spherical objects covered in a retro-reflective material which means they don't...

Robot Fusion
Log from Tote Zero
So I never actually made that board from the last log. But remember #Tote HaD, those robots that we have built at Hackaday Belgrade? I have spent a considerable amount of time designing that PCB, and it has a couple of Easter eggs in there. On of them...

Refactoring again
Log from Pi ZERO Arduino programming station
Another refactoring to the PCB is required. I haven't ordered it yet, because I knew somethign like this would be required.Since I'm new to Raspberry Pi, I didn't know that its levels are at 3.3volts, so by directly attaching 5volt Arduino I could damage...

Issue identified
Log from Voice control for Velux
After losing my day wondering why nothing worked anymore after the connector change an issue was detected. Having neat wires, soldered instead of jumpers demanded to much current for the remote to handle. It was working when connecting the remote with...

Into production...
Log from PiDP-10
Well, the last revisions to the PCB set have been made, and on Monday everything should have arrived so we can make the first 50 kits for daring beta-testers! But it will then still take a week for the packed-up kits to arrive at the fulfillment service...

Progress Report
Log from Pi Chart
Progress ReportIt's been a while since the last log entry - I've been very busy both with work and advancing the project.Raspberry Pi on/Off boardThe Raspberry Pi On/Off board has been built, but it turned out that the USB plug did not have a good mechanical...

Adding buttons and switches
Log from Pi-ADAS
Now that i have the platform i needed a way to make it convenient to use while in the car. At first i tried using it with no physical niput but it required to :have a laptop or phone connected to the device via wifi (the Pi acts as an access point)connect...

First prototype layout
Log from LiFePO4wered/Pi+
My prototype layout is done!Some OSH Park renderings below:All in all I'm pleased with the result. It was harder than expected to cram it all in, especially the larger (higher current + lower cost) inductors take up a lot of space. This board has the...

It's alive!
Log from LiFePO4wered/Pi+
After hacking on firmware for the past two weeks, I'm happy to report that the prototypes are working!Here are my two protos: running a Pi 3 and a Pi Zero W:The prototype in the back uses a 18650 LiFePO4 battery and stackable header, the one in the front...

Hose clamp and driver PCB
Log from PTSprinkler
I needed a way to clamp the garden hose on to the pan/tilt stage. While it would have been possible to use some metal strap or other standard clamp, I decided it would be neater to 3D print a custom clamp. It also gave me an excuse to design a 3D model....
