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 […]
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 […]
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 […]
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 […]
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 […]
With my final exam looming over the next two days, on power supply electronics, I decided to actually apply the knowledge I learnt for once to design a COMPLETELY makeshift boost converter for a high power LED I’d purchased previously (http://goo.gl/zFooZK – Link will expire!). I don’t really see the use for me to have […]
