Introduction
I recently had a need to wind a thousand turns of wire or so on a bobbin, but I might have needed to repeat it a few times each time the coil design needed tweaking. I needed a coil winder! This project might also be useful for ...
Hi!
I thought I would share my project from this past year, currently taking a month or two break to reach out to those who might be interested in building one.

This blog post contains at least two topics, both (hopefully) interesting. One topic concerns how to code new functionality into an exciting open source project called the Pico SCPI labTool. The end result discussed here provides four analog voltage ...
So I thought I'll let people know I have been working on a HAT for the Raspberry Pi, to allow easier implementation of a four player arcade with revenue service capabilities.
I have a YouTube video going over the circuit and PCB design.

Whatsapp has made communication very easy. We can send calls, messages, and video calls from anywhere in the world. All we need is Wi-Fi or mobile data. There is no charge. We can receive notifications from a gas sensor on our mobile phones through W...
With the shortage soon to be a thing of the past. (knocks on wood) We hope with the news that Eben stated in a few interviews. This is great but looks like Raspberry Pi 3's are going to be some of the first back in the 3rd quarter available to...
In emergency situations, quick communication can be a matter of life or death. That's why the Emergency Calling System with SIM800 and Raspberry Pi 4 was created – to provide a reliable and cost-effective communication system during critica...
Have you played number games with ChatGPT? It can play some math games with you. In earlier days of its development, one of such games were the math solving game. It asked you arithmetical questions one by one. And you had to answer. It co...
Another Pi Day and time for another Pi project .
About a year ago Lady Ada from Adafruit did a video series on using MCUs to read from floppy drives low cost and easily available floppy interface hardware. Amongst the the MCU boards ...

Hi all.
This is an updated version of my previous blog post - Use a Raspberry PI Zero W as a Wireless Print Server
One problem of old printers is that they don't have network connectivity and or can't be shares with more users - unless the computer w...

December has been a good month for USB-C Power Delivery projects and experimentation. I hope it continues into the next year.
Here are some new blog posts that were created during December! They could be of interest to anyone curious abo...
In this Upgrade Project, I Have provided the following parameters
1. SpO2
2. IR Temperature Sensor
3. LCD Display
4. Voice Broadcasting
5. Data Saving For Future ML Training
I added the basic details of different Classifications of blood pres...
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 ...

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 (...
