Jumbo Seven Segment Display

As always we’re sponsored by I’ve finally got the modular seven-segment display working. It’s been quite a journey (with a few mistakes along the way!).

Connect to an atomic clock with just two lines of code...

As always we’re sponsored by I’ve got some PCBs manufactured for the next video so don’t forget to subscribe.

I make a mistake and use it to look at the MHP30 - and I also see if my vacuum cleaner sucks

As always we’re sponsored by They provided the excellent PCBs used in this video.

Quick video - Messed up my PCBs so I thought I'd just test out the MHP30

Completely messed up the designs of the PCBs - there’ll be a video shortly to explain what I did wrong. So I thought I’d try out the MHP30 to get a bit of practice in.

Hitting escape on my wireless keyboard battery addiction

As always we’re sponsored by - I’m waiting on some components so I can solder up the latest set of boards so I thought we’d do a bit of a hack on my old wireless keyboard.

Forget SSH and vim, Use VSCode to Remote Develop on the Raspberry Pi

Remote development on the Raspberry Pi with VSCode. As usual, we’re sponsored by

Bootlace Crimping - What?, Why?, How?

Just a quick video - I’m slowly building up my collection of tools - I’ve now added a bootlace crimper. This is for crimping Bootlace Ferrules (as you might have guessed from the name…). Thee are sometimes referred to as Cord End Ferrules.

Princess Leia Hologram

Some silliness to keep you all entertained. You can see the full video of how this works here:

Completely BONKERS Spinning LED Hologram Fan - Watch out for your fingers!

As always we’re sponsors by I saw a demo of this mad contraption, and I just had to buy one - it’s a spinning LED fan. It’s completely mad.

Supersize Seven Segment Clock

The PCBs came through from a couple of weeks ago and I’ve finished (are they ever really finished?) the project!

Watch me mess up some soldering and take a look at the Andonstar AD409 microscope

I’m trying out the AD409 microscope from Andonstar ( or This is a great bit of kit with a nice big screen so you can really see what you are doing.

#Shorts - Wordle solving robot

We’ve made a wordle solving robot! Watch the full video here:

Couldn't resist it: "And here's where I keep assorted lengths of wire..."

Everyone seemed to like the picture of my organised wires, so why not do a video as well :)

The PCBs are in production - what have I messed up?

I finally got the PCBs into production with - it’s Chinese New Year, so we’ve got a bit of time to sit back and reflect on what I’ve messed up in the design.

KiCad Tutorial - Custom Symbol, Footprint and 3D Model

Adding a custom footprint and symbol to KiCad is surprisingly straightforward. As always we’re sponsored by

5v to 120v DC Boost - only one chip was fried in this experiment…

I saw these LED filaments on Big Clive’s channel and wanted to do a project with them. As always we’re sponsored by

PROSTER BM4070 Digital LCR Tester - quick look

After the DIY LEDs project, I thought it was time to invest in a proper LCR meter - so I got myself a cheap and cheerful one from Aliexpress.

Amazing online Arduino and ESP32 simulator works in your browser.

I just came across WokWi ( - an online Arduino and ESP32 simulator that runs in your browser. As always we’re sponsored by

I've got 150 breakout boards to test

I had some bulk orders for microphone boards so I thought I might as well order a few extra to put on eBay. I’m not currently doing Tindie at the moment as they haven’t got their act together on VAT which makes selling in Europe a bit tricky.

SMD Wireless LEDs - as good as the commercial versions?

SMD wireless LEDs - what’s not to like? I showed in a previous video how to do this with through-hole components. These worked really well, but they weren’t as nice looking as the commercial versions.
