good news and bad news
Added 2024-08-04 22:11:41 +0000 UTCI have good news and bad news. The good news is that I scored some monster magnetrons recently. In fact, I was searching for this specific type of magnetron for years, and then recently a fellow high voltage nerd tipped me off to some that were for sale on ebay. These guys are rated for 10kW output power of microwave radiation. That's more than ten times higher than what's found in a standard microwave oven! I have a lot of things I want to try with these, but highest on the list is making an audio modulated microwave plasma. I'll probably also try jamming one in a microwave oven in order to make a turbo microwave. A macrowave, if you will.
So, the bad news. I've had a couple embarrassing failures with my 400W laser project. After a few initial tests with the laser, the control electronics randomly burned up on me. In fact, it actually latched the laser on even after letting go of the trigger! Thank goodness I stuck a mechanical switch on the thing, because that could have ended badly. The laser arrays were fine, but I had to rebuild all of the electronics, which took me weeks. I never identified the cause of failure, so I changed out the driver type thinking that might be the issue. Everything tested out great, but once everything was put together, it happened again! All the electronics are toasted. The problem must be a hidden short somewhere because I can't find any other issues.
Now I have to decide whether I want to try building it again or put this project off for the time being. The circuitry isn't even complicated, but since everything is free soldered or on perfboard, and jammed into a small space, it is soooo tedious rebuilding all of it. I hate electronics sometimes lol.

Haha Thank you for what you do sir. Your videos are as funny as they are educational.

2024-12-23 05:23:18 +0000 UTCI notice the cooling ports - makes sense for that much power. So you think there is a short when assembly happens? Some unknown item has a case that is electrically active or... Care to share a schematic?

2024-08-06 02:40:03 +0000 UTCYo, that thing is a monster! looking forward to a macrowave vid if you do one lol and I've got a few cheap microwave burgers here. curious if we could get the cook time down from a minute to 10 secs. I'm sure that wont make them any less edible

2024-08-05 01:46:08 +0000 UTCyes in theory it'll heat food ten times faster, and yes the heating would be quite a bit less uniform as well. the power may end up being too great and just char the food in spots or even cause the air in the oven to breakdown into plasma

2024-08-04 23:11:31 +0000 UTCyou can do it styro I believe in you

2024-08-04 22:22:05 +0000 UTCYou'll figure out why that happens, electronics can be indeed troublesome.

2024-08-04 22:21:07 +0000 UTCIts like "hey bro, can you warm this leftover pizza up for 2 seconds." ππππ₯π₯*ding* done. So, would it be 1/10 the time required since its 10x as powerful or what? Just for regular purposes. I wonder if the hot and cold spots from the nodes might be extreme also?
