Amazon messed up the release AND the bonus code. A bunch of imbeciles. No wonder their spaceship also explodes in place.

Haha! It's always great to save. And baking the whole thing is too dumb to my standard. I hope you put some blobs of silicone sealant on/in between those components with cracked joints, as it's an indication that vibration affect those. This is why you see white blobs inside PSUs!

I never like it that way. The block always becomes burnt and messy. However this method doesn't seem to infuse much into the wick. I'll test later when the roll dries up and see if it works well.

Jeff Chen @jeffchen.bsky.social · 02/10/2026
I tried lowering just the tip of the whole roll and hoped it would “wick” the liquid up into the roll. But it never worked. I had to unroll the entire thing onto the bottle and let it soak🫠 Afterwards, I rolled it back up and checked the liquid level - it didn’t suck up much🤔

I pried the piece out of the paper box and put it in a medicine bottle. Then I dropped some ball bearings and closed it. Then it’s maraca time until everything is pulverized😂 Then I added 3 times the 99% IPA to dissolve it. It worked fine😌

Saw someone letting a roll of copper wick suck up some Hakko liquid flux earlier today. I bought a roll of wick that came with some solid flux from AliExpress a while ago. So here is my experiment👀

It's at least a piece of description of one's perception and/or experience of something, so it would just be completely subjective. No surprise🫠

I've been to some convoluted discord servers just to access some tutorials and downloads, but ended up feeling they are making you do this and that just to pass some kind of test to enter a cult. Quickly backed out after I got what I wanted🤡

My guess is one of the caps was put in backwards cuz the silkscreen on the PCB lied🫠

This is Sony TGV-3 TV tuner unit. It goes on the side of a GV-S50 portable video recorder. I’ve mapped out the pogo pins of this unit so I can use it standalone and output composite video and audio. Look at this crazy jig I designed for the job🤡

I have successfully fooled the TV tuner and turned it on😂 Though the video levels are all messed up. I need to look into that😅

However the speaker output still doesn’t work and the machine heats up suspiciously on the right side until I plug in a headphone. The cassette holder doesn’t retract with a tape inside. But this is not my concern atm so I’m not spending my time trying to fix those😌

Jeff Chen @jeffchen.bsky.social · 28/09/2026
And it’s now working much better! The image is not rolling anymore. Ejected holder will reliably retract. This allows me to sniff the LANC bus comfortably at least - what I bought this machine for😌

Jeff Chen @jeffchen.bsky.social · 28/09/2026
I had no tiny SMD electrolytic caps on hand so I had to use all my PLCC caps instead. It’s not optimal, but it should at least make the machine work better than dead & leaked OG caps🫠

This Sony GV-S50 gets a rolling picture from the tuner pack that needs warming up and only stops rolling when the image is dark. The cassette holder does not retract after ejected. There is also no audio from the speaker. My money was on all these caps🧐
