polyester concept posted:yeah that’s totally fair, it’s not something I am really passionate about anyway. but it sounds like it might be much easier to go with one station by just using an off the shelf fm modulator. really i just want to use my vintage receiver because it has pretty lights with the radio on, and I never listen to actual radio stations single modulator is the fun way. if you want you can do it with a raspberry pi and just generate a crude RF signal by twiddling one of the gpio pins real fast. somebody else in here has this setup i think. if you're keeping it on coax there's no real FCC worries

I think it cost $100. If you want multiple channels it seems like just modifying whats playing is a better idea but if you want to listen to A in the kitchen and B in the garage just buy two i guess idk

I haven't tried squeezing multiple carriers into the same GPIO pin yet but now I kind of want to.

when did that weird anchor syntax become a thing, anyway, was that just google inventing poo poo out of whole cloth for chrome istps: converted a long-running php script (record 1s audio, feed to sox, send max amplitude to HA) into a systemd service, then set up HA so that it can ssh into the host machine and run the service stop/start commands. now i have a toggle switch i can use to enable/disable the audio monitoring whenever, like if we're out there

Jonny 290 posted:I dont see too much of a hurdle to that yeah. could be neat. Got nerdsniped super hard by this so I simulated it for AM radio with 5 carriers. The sample rate of the digital signal is 12MHz and even with only that the carriers show up in a spectrum.  I included the time domain signal in the plot just to show that it's really just a digital signal with a relatively low sample rate, delta-sigma modulated, but the 5 distinct carriers still show up above the noise. It might be possible to do multiple stations on a cheap FPGA board without a fancy DAC. The tricky part would be getting the audio in.

a printing service is trying to solicit our students so they sent us a huge box of sample fancy printed materials. glossy inkjet prints, metallic embossing, rubberized paper coatings, yada yada. included in the pile were a dozen of those electronic cards that talk at you when you open them up, programmed to spew a banal marketing message. i tore one open and there's a speaker (obviously), cr2032, 16-megabit flash EEPROM, mp3 decoder ic, and a usb port. plus a hall effect switch to trigger it, which could easily be rewired to a limit switch or tilt sensor or whatever. thus: https://i.imgur.com/ZZXKlDD.mp4 what should i do with these?

Have students make 3D printed dispensers, you know like gumball machines. Integrate those things. Then whenever the crank turns, the hall effect sensor triggers big_grunt.mp3 right before the plop of whatever comes out.

just spent a few hours setting up asterisk/freepbx for a home phone and realize now that the Cisco 8841 I bought off eBay 18 months ago needs a license that's like 3x that cost just to work without a CUCM. That's what I get for thinking I could just roll in with tftpd and send a config I guess

not sure if I want to post my javascript project yet, but so far there's a collapsible list of stations/planets, you can make & name your own stations, and there's a stardate clock that ticks up (I had it saving to localStorage at one point but I'm lazy to fix it atm) not bad for a first project but it's not much of a game yet (much like my godot version)

Jonny 290 posted:the time efficient way is to buy a bunch of fm modulators and use a combiner to put them on the coax obviously the yospos way is the superior way, since it lets you play with fun toys either way you’re transmitting FM, when you use a length of coax you just have the transmitter and receiver touching so they don’t really need to radiate

the yospos way would be to run an E1 to 10baseT converter and a 10baseT to 10base2 converter so you could run like, Idk 4xE1 so 120 voice channels over a run of RG-58 coax

sweet, noticed color widget stuff updating decker the other day, thought it was an older "secret" (much like color afaict started out in decker in general). spending a lot of time in decker atm, having a lot of fun. involves pushing pixels into it from emscripten lumps though, so not very in spirit of the singular deck.

i picked up a new istp today after work. (sound on) https://i.imgur.com/n7yQ0Um.mp4 it's a mac se, with 1mb ram and dual 800k floppy drives. don't have any 800k floppies, or anything else that can even write to them. it's fine. i'll pick up a scsi to sd adapter or whatever. it needs a bit of a cleaning - there's some corrosion on the scsi and floppy ports on the back, but otherwise it's in great shape.

Elder Postsman posted:i picked up a new istp today after work. I've got one of them, I picked it up a few years ago from some guy on Craigslist. When I got to his house he was in the basement, playing some games "one last time" and as with the other Mac Plus I got off some other guy on Craigslist, he made me promise not to turn it into a fishtank (I would do no such thing). It also seemed like he was playing games without any floppies, so I asked if it had a hard disk and he insisted it did not. I got it home, turned it on, and it booted right into macOS, with a bunch of games, apps and After Dark installed, so it definitely has a hard disk. Both floppy drives work so it's an aftermarket kit since Apple never sold it with the 2 floppies + hard disk combo. My idiot project with this one is to write an app for it, I haven't decided what the app will do yet though.

Oh, I do have a related project I am looking for help with, though, if anyone has any suggestions. Basically all my antique computers are currently in the garage with all the spiders, by the water softener. I don't really like that and I want to bring them inside, into a room that used to have a bunch of book cases but I had to hide all the books from my toddler (I am pretty sure the antique computers will be fine). Basically, what I want is some shelving unit that's configurable - enough space to have a section for that Mac SE, one for a shared monitor, ones for a couple of other CRT systems, but also a few drawers (I was thinking the drawers would be good for all in one style older computers that plug into the TV like the Amiga, BBC, ZX Spectrum, etc.) Does anyone know of any configurable cabinet products I could consider? I don't want to have to make it from scratch (though it's always an option)
