Engineers don’t only build, but fix. Most of the time, I don’t have a problem with the latter. It’s only tedious when it comes to troubleshooting circuits. Turns out, there was no current flowing at all, right off the bat. I guess this says a lot about my soldering skills.

Instead of going to school and watching Jackie Chan movies, I spent three afternoons soldering components onto a perf board. The aftermath- It can result in a mess sometimes. After soldering, I moved on to the part where I usually disappoint myself — testing. Looks incomprehensible, right? It is! There’s […]
Thank you all for being here today to honour the life of our dearly departed NPN 2N3904 transistor. It’s hard to stand here, but I’m grateful for every current you amplified and for the times where I’d mixed your emitter and collector up. You were everything I could’ve asked for […]
After many rounds of testing (and soldering), I finally got the potties to work. First up: volume control. Going clockwise, the volume decreases. Going anticlockwise, the volume increases. It’s the most obvious out of the two. Next: gain control. This might be hard to tell. Potentiometers are technically called variable […]
The title is not what you think. Pots stand for potentiometers. I learnt a bit about them today. These little things are the knobs you turn to control the volume on an amp. I’m planning to add two pots in my pedal: a A100K one, for the volume control, and […]
Here it is! My dad ordered it from Shenzhen. It’s a city in China, where all these electronics kits are manufactured from. So now you know. You’ve got the power source (VCC), the switches (SW1), and the resistors and their respective LED diodes (eight paths in total). You might have […]
It’s been more than a week and we haven’t moved past the Clipping Stage. Oh well. My dad suggested I use LTSpice — a software that lets you build a circuit and measure its current plus voltage. It’s not very user-friendly (or pretty, for that matter), but it gets the […]
Here’s what I’ve been talking about over the recent blog entries: The Clipping Stage! Disclaimer: It’s still not complete; there’s supposed to be an additional capacitor and diode, but we’re testing the resistors and transistor first. R1 is the Green Resistor, with a value of 510kΩ. It’s connected to the […]
