Another PCB : building a network on an oily rag
Log from SentriFarm
So far I have prototyped the MQTT_SN code and have the software communicating over radio between OpenWRT and a BusPirate. However, the BusPirate with an extra serial layer between SPI and the software is not fast enough and often drops messages. So we...

Pi-bridge custom shield
Log from SmartHome
Here is the custom shield I built for the SmartHome central station.Every Raspberry and ATmega328 pins are broken out, 5v and 3v I²C buses were added, the serial communication could be enabled/disabled with some jumpers, there's also a socket for...

MSXPi Batch Assembled
Log from MSXPi Interface
I made a batch of MSXPi with PCB manufactured in China - the final PCB are actually of good quality.Since it is not a begginer project, I decided to assemble all units and sell almost ready to use - yes, almost because the full project requires...

TEST SETUP hardware completed.
Log from LOAD CELL to MODBUS
1, 2, 3, 4, 5, 6. Independent weight scales. Each consists of the load cell and Load cell - Modbus converter (PCB w/o housing)7. DIN enclosure with Raspberry PI3 B+ inside.8. IOTON PI-FACE (my interface for Raspberry PI with RS485, RTC, UPS, power controller,...

Proof of concept
Log from Intelligent Breadboard
The final product will be based around a custom PCB, but I want to create something quickly that I can use on current projects.To start with, I'm going to use components I have to hand: a standard 400 point breadboard,and Raspberry Pi based port extenders...

Changes to PCB Design
Log from Cosmic Array
Very pleased the first prototypes worked straight off , without modification. The new board design includes a 2A 5V supply for running external devices like a Raspberry Pi, Pad spacing changes for some components and the ability to add terminal blocks...

Got the font sens PCB
Log from Open Source All-In Drone-Droni SAME70Pi (Kopernik)
Just got the PCBs of the front sens, the assembly will follow.The Raspberry Pi Cameras will be placed in the front, hopfully to do stereo vision with the compute module.There will be also sensors (gas, temperature, baro in there).

PCB TOP Assembled (part 1)
Log from Open Source All-In Drone-Droni SAME70Pi (Kopernik)
I assembled the following parts of the PCB TOP:- the SAME70-M1/M2 circuits- the headers of the xBees- the connector for front sens- the RPi Cams connectors- the Raspberry Pi compute module socket and circuit- the radio Si4464

3D Printing the Tray
Log from APC UPS NMC from a Pi
I've been tweaking the 3d printable design for the tray. Tabs and panel cutouts fit a Raspberry Pi 1, but can easily be adjusted for any model. I've also included a way to hold a piece of PCB in place, so it can slot directly into the card edge reciprocal...

new PCB design
Log from 8mm Film Scanner V2
In order to provide cooling to the Raspberry Pi 4, the new design has space for a cpu cooling fan. The GPIO assignment is new - so it is not compatible with the software of the original scanner.It also includes now a switch to toggle between S8 and R8....

Back 4 good
Log from TextEye: Raspberry Pi (Zero) Mobile Textreader
Hello everyone,Sorry you all had to wait this long for an update. I'll try to get back to posting more regularly in the upcoming months.So what's the current status of the TextEye?New hardware optionsSince I started the project last year, a few new hardware...

Progress
Log from carbt_v1
I have been very busy working on this project since the last update, and I think I have something worthwhile to show now. During that time I have gotten bluetooth to work, rebuilt the display module, and done a ton of programming. I guess I will get...

SD Cards Formatted
Log from Retro Pi Christmas
After a hickup associated with Windows 10 Technical Preview BSODing my laptop, and my Virtual Box not seeming to accept any USB devices, allthree SD cards are running Retro-pi 3 for Raspberry pi 2, each with the ROMS installed.Following the previous,...

Starting on a test PCB
Log from Modular Open-Source AV Receiver
Today I worked on a PCB for proof-of-concept, essentially it will be an adapter to a Raspberry Pi header.One module will have a Raspberry Pi, one module will have a Pi DAC module.Once this is working, I will be able to use it to check other custom modules.So...

Honey, I Shrunk Our LiFePO4
Log from Ye Olde Nowt
Both the new PCB and the #LiFePO4wered/Pi arrived while I was away, so I can now get back to hacking. But what is this? It's too long for the the Raspberry Pi Zero, as it was originally designed for the Raspberry Pi B, which is a little bit longer. But...
