Zoom H4n Pro Repair

A Zoom H4n Pro audio recorder found its way to me, non-working. Recordings seemed to be silent, but with loud enough input you could just make out some distorted sound in the recording. After (unneccessarily) disassembling it completely, I found out that the power supply of the preamplifier board was sitting at around 0.8 V, which thankfully/boringly turned out to be the only fault in the unit.

Using Desoldering Braid Bobbins for Bodge Wires

Don’t throw spent desoldering braid spools away! The bobbins are great for hand wiring prototypes and doing PCB repairs. They have the perfect size, and unlike a regular spool, the magnet wire won’t uncoil itself all the time.

This post was the first post of my first attempt at a blog (which was never published). Albeit I since re-wrote it completely, I decided to keep its original date, which consequently now predates the date this site went online.

I still like analogue scopes. Although the convenience of a digital scope’s features is hard to be matched, I still like to come back to the older world from time to time. Why? I have yet to meet a DSO which is as satisfying to operate as even a basic analogue scope. On a DSO, no matter the price point, you always notice there’s software handling your input, given the ever so slight lag. Not to mention the overall haptics; rotary encoders and rubber push buttons just don’t compare to the real deal.
