after a sucessful repair its taking apart my house again
i sprayed the membrane with liquid rubber to conserve it, doesnt change the sound. full cap replacement, replaced half of the transistors and the a2611 optocouplers.
the rattling comes from stuff in my room being rattled into a pile of undefined mess of matter
song hey now from london grammar

a one cylinder switch operated solenoid engine
at the first part you see it running, later on i show you how i made it and what mistakes happened.
link to all files i created for this project, some was tests, some others didnt really worked. plus the sketchup skp model file so you can fiddle around on your own.

i used PLA plastic for all the parts on a Anet a8 printer.
i mentioned that i bought the printer by myself because many youtubers got this model for review / for free, which "could" have influenced their conclusion. But the printer is very good, if you look for something like this, get it.

fuck yea it just got released. this is going to be the best farming sim when its done.
Releasing a tech demo after its kickstarter campaing, it their first big step to a final game. many things are missing or bugged but this has potential, its running much better, look better and works better than farming simulator 17.

driven by two TAS5613A running in BTL for a total of 600W theoretical power at 3 ohms.
im running it far below that for testing, the pcb is probably not suited for that power anyways. 1oz copper is not much.
i used easyeda and jlcpcb, they didnt sponsored this video. but hey for 2 bucks i recommend them any time, no need to pay me.
schematic and designs can be found on my easyeda page: gamerpaddy
still work in progress, i made a few mistakes on the pcb thats why there are solderbridges. thats how it is in prototyping stage.
for full output power i would need to drive the chip with 7V differential/balanced instead of line level 1Vpp (2V) so preamp is needed.

Just a quick video about a logitech Z5500 with a flickering blinking backlight, non responsive to button presses and no sound at all.
It turns out to be a 25V 4700µF that has rattled lose, a leg broke off.
Quick Fix, Quick Video.
