Back in Experimenting with Thermistors, I described the challenge I had with Bitcoin miners heating the warehouse area I use as a training space. Recently, we had three small upper windows installed that I can open. The original wind...
I know how to use plain UART on the Pico, with receive interrupt. See advanced_uart.c.
I also know how to make the UART show and work as a COM device. See hello_usb makefile.
I'm looking for help on the following: use the USB as a COM, and ...
Introduction
In this blog I explain how I created a solution, which displays real-time train arrivals data for a station platform (i.e. in one direction) on a 20x4 character OLED display using a Rasberry Pi PICO-W board. The motivation behind this p...
I saved up for 6 weeks to buy a 7" Touchscreen and I don't know how to install it on my Raspberry Pi B+ V1.2 because there are no instructions in the box and I can't find them online. The box doesn't even say what model s...
Hi all ! Hope everyone is well.
Just want to share my latest project - a water cooled Raspberry PI.
Why ? Well, since I was a teenager (I'm from the 80s) that I wanted to have a Water cooled Desktop PC. I first saw one in 2004 at a Lan Party (...
Interfacing Nine DS18B20 Temperature sensors with Raspberry Pi and Displaying sensor data Using Python
I have gone through some tutorials for interfacing the DS18B20, In those, They have given the explanation of how to interface the DS18B20 using Ar...
SDR++, The bloat-free SDR software
Here is the link to my video for this

This assumes that you have already installed your SDR drivers, for the RTL-SDR I use the Osmocom ones from https://www.rtl-sdr.com/rtl-s...
I found it necessary to create this article for a few reasons
Most of the YouTube/Instructables focus on aerials or only Windows installation
The ones that are for the Raspberry Pi are out of date

My brother who is a wood working enthusiast asked me about electronics for making a BLE speaker box with the form factor of a mid-century table top radio. His inspiration, which I really like, is this:
He had found a BLE receive...

Just how fast are interrupts serviced on a Pico running the Arduino framework? Fast enough!
I sort of have the Arduino environment for the RP2040 setup in VSCode thanks to PlatformIO. But, not totally, just yet.
I made a basic sketch registering a ...
I recently picked up a Pimoroni RPI Pico Display board. https://shop.pimoroni.com/products/pico-display-pack
What do you even call these little addon boards anyways: toppers, hats, I don't know. The display comes in package that almost looks...
This Power Supply has been available for a while perhaps, but I just noticed it now, it is just £11+tax, which is very good for a (hopefully) safe power brick. The information here is just informational : ) use caution with supplies capabl...
This is a project to demonstrate how to use the raspberry pi to interface to an industrial RS232 device and send it's data elsewhere over an ethernet WiFi link. This could be done over a hardwired ethernet link or as in this case over the W...
