Each week I will grab a random electronic component from the vault and build a circuit - this week I look at a venerable tatty project and update it with some modern know how.
Each week I will grab a random electronic component from the vault and build a circuit - this week I look at resurrecting a couple of "dead" Arduino UNOs by swapping out the ATMega328 for an ATMega88.

Each week I will grab a random electronic component from the vault and build a circuit - this week I look at some simple circuits involving buttons, WiFi and BLE to change LED traffic lights.

Each video I will grab a random electronic component from the vault and build a circuit - this week I look at a old/new addition to the lab - a lovely analog CRO oscilloscope. One day I might even learn how to drive it properly!

Each week I will grab a random electronic component from the vault and build a circuit - this is a republished version of an earlier video where I used a 555 timer in a circuit to generate a variable square wave.
I republished because YT were unhappy with the background music - sorry YT!

Each week I will grab a random electronic component from the vault and build a circuit - this week I look at 7W LED Cobs to better light my work area. There's 3D design and printing as well, it's very exciting!

Each video I will grab a random electronic component from the vault and build a circuit - this week I make the third major iteration of a hallway light project. It gathers energy by day and then guides your path at night - nice!

Each week I will grab a random electronic component from the vault and build a circuit - this week I look at spicing up "normal" OTA programming by using the device itself as an access point for the programming!

Each week I will grab a random electronic component from the vault and build a circuit - this week I was trying for a counter using a CD4026 but sadly ALL the CD4026 chips I had were either broken or more likely fake. So here is the Attiny13 counting - and watch this space for the "real" version when the new CD4026 chips turn up (assuming they work!).
