Kinda having a bad time with anxiety today. May I please have some recommendations for fantastic Youtube Poop to help get the right brain chemicals on deck?
Wow, modems got TURBO JANKY for a while, didn't they... Supposedly this is just a PCTel reference design, with pretty much everything not absolutely needed stripped off.
In case you're wondering how these worked without an isolation transformer, the secret is in the "Silicon DAA" design. Everything on the phone line side of the modem is powered only by the DC voltage on the line. Serial data communication back to the PCI interface chip is passed via the seemingly random value 2KV rated ceramic disc capacitors.
In case you are wondering if this worked at all: yes, in most cases.
In case you are wondering if this was any good: lol NO
I'm looking for recommendations for things to help introduce someone to the world of electronics, both instructional materials and hands-on activities like kit building. I've run into a few people now who are really interested after learning about some project, like console modding or repair, and would love to increase their knowledge.
@recursive I have enough that I could easily bench test an old analog broadcast console that needs +/-18, +/-12, +5, and -48 (though this is usually optional and only needed if you are using the internal mic preamp and condenser mics)
I forget which the goofy one was I was working on that needed +/-18 and +/-12
I love that some time ago I basically infected my coworkers' minds with this and the message worked: when they're about to do something dangerous they step back and think of "shake hands with danger" and that guitar riff. then they burst out laughing.
Today I spent some severely side-eyeing a truck mounted vsat rig trying to get it to find the bird
(Instead the system just kinda kept flipping me the bird, going through a coarse search over and over and giving up without seeing a signal at all, I think the ODU went kaputski)
@MLE_online the neon one is guilty of the staining. It's got this perplexing little map on the back of the palette showing which ones are intended for use as eyeshadow and which aren't. I don't understand this at all nor do I care. You can't even see this map when using it.
