Building a computer without case to be mounted on a wall. Every cable managed away.
I always wanted to build my own tube amp since I heard about them because they are quite expensive. The problem is that most run on high voltages (around 300V) so it's not safe to poke around in. Now I'm gonna make one that runs on 19V.
Thomann just released their own amp attenuator. Let's measure it and take it apart.
I read a few articles about BTRFS and ZFS and about cheap chinese electronics so I thought I should combine that. So I bought the cheapest 1GB usb thumbdrives I could find on ebay. With four thumbdrives I can test various raid setups with BTRFS and ZFS and benchmark them.
A few weeks ago I replaced my Line6 Podxt live multieffect pedal with a guitar amp, cabinet and 2 pedals. The amp is a Kustom Defender 5H head and I use a Kustom 1x12 cab with it

Last week I received a broken Logitech 2.1 speakers set. The Logitech z-340 specificaly. The power light turned on but no sound and the volume knob produced a crackling sound when turning so the amp in the subwoofer is still working. I've tried disassembling the subwoofer but it's mostly glued together. So I first reverse engineered the speaker unit. It contains a small circuit board with the controls for the subwoofer. The left speaker and the subwoofer are connected with a 10 pin cable with din connectors. The speaker unit also contains a preamp for the headphones output
