The Neon Clock – Part 2

Today, my PCBs arrived, wahoo! Therefore I’ve been able to have a quick go at making my neon clock. I tested it in parts to make sure each section worked before putting it completely together. Unfortunately, my high voltage PNP¬†transistors haven’t arrived yet so I’m currently testing it with TO92 transistors in their place. Testing […]

The Neon Clock

Building a clock really is about as textbook as it gets when it comes to electronics projects – especially on the internet. I however have never build a clock (not intentionally anyway… I wouldn’t count the measily effort of my smartwatch!) so I’ve decided to have a go at one. Instead of doing one of […]

PIC10 Constant current LED driver

To ensure LEDs have a long life span, the brightness and power dissipation can be controlled by a constant current source. Dedicated ICs are available for this task though having already designed a buck converter with the PIC10, I thought I’d have a go at extending this to controlling the current through an LED. The […]

PIC10 Buck converter

Well! My new PicKit3 has just arrived and in my last RS order, I got some PIC10F320 chips. The reason I chose these chips out of the massive array of PIC microcontrollers is because it is from the cheapest range (PIC10), features a hardware PWM module and an integrated 8bit ADC. I’m always interested in […]

STM32F0 Simple Boost Converter

Having changed my degree title from Electronic engineering to Electrical and Electronic engineering, means that I have to take some power modules. While I don’t find mass power transfer particularly inspiring (HVDC links, the grid and power networks blah blah blah), I find small power conversions pretty interesting, the low power stuff that enables us […]
