Log from Vinduino, a wine grower's water saving project
LoRa Sensor GatewayThe Vinduino gateway receives LoRaLAN sensor data from the Vinduino sensor stations and forwards via WiFi to a ThingSpeak account. To date, the Vinduino project has been using an Electric Imp solution, which required some soldering...

Raspberry Pi - Sprog - DCC Train Control
Log from Not Just Another Coffee Table
The model train world has moved far forward from the old-school days of analogue current motor control. It's now possible to have multiple trains on a track with sound effects, lights, and motors, and control these trains with ease. DCC (Digital...

Going into this 20Msps to 40Msps pHAT for Raspberry Pi
Log from 20Msps+ ADC RaspberryPi HAT
Problem and solution!Problem was that the Pi0 or PiW, with the current kernel module, can't run faster than around 10 to 12 Msps. Clock can be faster, but the memcpy limits the transfer to memory. Soooo.. what can we do? As a reminder, I wanted at least...

TinyUSB + Raspberry Pi Pico = USB-Readable Psion SSD!
Log from PsiDrive - A USB Psion SSD Drive
Just a quick update: After spending a few hours playing with the Adafruit version of TinyUSB for Arduino, I can now see a Psion SSDs as block devices in Linux! The status is: ROM SSDs: Readable, but no FEFS drivers in Linux. However, DD works fine, so...

Pi connections
Log from Web powered antique wind gauge
I'm intending on using the RPIO library to drive the servo from the Pi:https://pythonhosted.org/RPIO/pwm_py.htmlSo I need to connect it to the GPIO pins somehow. I struggled a bit to find a breakout board that didn't just connect to a breadboard or a...

Assembly of Pi 2 WiFi Box
Log from Einstein-Rosen Bridge (WiFi)
The assembly of my Raspberry Pi 2 based WiFi box was very straight forward. The power USB cable on the Pi 2 was a bit snug against the veroboard for the GPIO header breakout but it went in no problem after trimming a notch out of the board.Once it all...

Log from Internet of Things Microscope
Tonight we came in and wanted to get a proof of concept for the microscope. We initially started with a Raspberry Pi 2 and hooked up the Pi camera. We used a plastic lens from a cheap laser to get a magnification. We used a Raspberry Pi A+ board as a...

Back To It
Log from RetroRiter
Getting back to work after a bit of a hiatus.I want to get things turning on. Which means power. Which means connections. And the "power distribution box." I've decided to forge on without bothering with a PCB for the switches / connectors on in the...

CANPi Hello World!
Log from CANPi
I haven't had time to properly test my CAN adapter for the Raspberry Pi until now. In the picture the CANPi adapter is on the Raspberry Pi, and it is talking to the purple PCB in the middle of the picture. The red Arduino shield is only used to interconnect...
