I used to love soldering and have hands-on at anything. Today, Hugo and me helped out Dr Tate and Vic in guiding younger students build their own Electronic Decision Maker. These things are more fun than the AM radio we did in our first year. The design has a lot of engineering in it – a lot of thought went behind the design and packaging. The objective was clearly to make students want o do electrical and electronics engineering – without them realising, it is not as easy and fun as it seems!
Well, helping the students out was fun – especially when the circuit was pretty simple and they were not really a curious bunch(unlike first years when I do lab demonstrating). Anyhow, Hugo and me were so keen on making our own toy – so Dr Tate agreed to allow us. Soldering on the PCB was never easier – took me just 5 minutes to solder the whole thing – something I am proud off! Check out the device – it basically squeals when you put two fingers across the connector(at the same time the LED flashes according to how much resistance the skin gives) and when you remove your fingers, the capacitor slowly discharges and the LED will alternate until it stops at one of it(making decisions of Yes, No, Maybe and Repeat) to any questions that you have!
