Two-hour soldering exercise yesterday. It’s pretty darn fun. Change my mind. The final product: bulbs, plus resistors from the previous post—

Great news! I just received a brand-new batch of resistors. Bad news! I mixed them up, and my multimeter is funky, so I’m left to learn the peculiar skill of reading resistor bands. I had a go at one yesterday for a short while — around 10 minutes — and […]
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 […]
2N3904, you will be missed. Moving on. I just re-tested the stage from yesterday. I should REALLY learn how to read the bands. My big brain couldn’t differentiate these resistors: Going from left to right: R2 and R1. They’re used for the schematic below: Everything but V3 worked today. Apparently, […]
Here’s my circuit now, for future ref. I might need to move some parts around, because it’s totally not working at the moment. I spent three and a half hours testing the “clipping” stage of the circuit. There was no current on the oscilloscope at first — turns out we’d […]
