Each week I will grab a random electronic component from the vault and build a circuit - this week I use a HT7850 regulator to first set a linear 5V from another source, then finally to partially tame a joule thief QX5252 circuit and....blink an LED (of course).
Each week I will grab a random electronic component from the vault and build a circuit - this week it's the ULN2803 IC.

This adapter makes prototyping on a standard breadboard easier, as it organises your components on one board for easy access and use. You can solder on any 1206 format components such as resistors and capacitors in any combination. You can even build up mini circuits such as a resistor/LED combination or a low pass filter.

Each video I will grab a random electronic component from the vault and build a circuit - this week I look at a ragtag collection of parts arriving into "Downtown Tasmania" - enjoy!

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 use a design from David Johnson-Davies on his technoblogy site to make a pretty useful function generator.

Each week I will grab a random electronic component from the vault and build a circuit - this week I get angry (?) at a dodgy bunch of LM7805 linear voltage regulator.

Each week I will grab a random electronic component from the vault and build a circuit - this week I make a 3D printed clockface for a "diffusion clock" as designed by David Johnson-Davies on his technoblogy website.

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.
