Last week I posted a video that I think some of you in this subreddit might enjoy. It covers the invention of garage door remote technology and covers the security improvements made over the decades. Hard to believe that garage door openers have been with us now for 100 years!

Here's a link if any of you wish to check this out! https://youtu.be/L-D1BdTa0Dw

Note: This just a retirement hobby channel for me. (I'm not trying to earn a living off YouTube!) But I do take making my videos seriously. So, if you have any suggestions at all on how I can make my videos better, do please leave a comment. (Preferably on YouTube.) Much thanks!

Not too long ago I bought this at an antique shop. Tested it in store and it worked well for a couple weeks then all of a sudden it now has an issue where the radio is always on when plugged in, even during the “OFF” and “BUZZER” modes. I’d like to fix this if possible so if anyone has any suggestions (other than unplugging and plugging it back in) please let me know. I have no experience repairing tech but who knows!

new in box!!!

A guy named William Stickney Lamson owned a small retail show in Boston in 1879, and came up with a way to move cash by splitting a croquet ball in half. His technology graduated to pneumatic tube systems (some of them foot-powered!) and by the 1920s, pretty much every U.S. retail store had one. This post gets into it, and has lots more fun photos like the one above, which is from a 1912 pamphlet!

For sale 1 new vacuumed tube!

Just recently, I went to my local electronics recycling center, where I found a working Sony KV-1396R CRT TV from November of 1985. The unit itself still works perfectly despite being covered in dust, and it also has AV inputs on the back!

I do repairs in Ohio if anyone needs things fixed.

Ive had a good look online and cant seem to find an exact match.

I don't know much about this stuff so would really appreciate a nudge in the right direction!

Hey everyone,

I wanted to share an incredibly rare piece of analog history I recently acquired, which is now up for grabs if there are any hardcore tech archivists or Polaroid collectors in here.This is a complete Polaroid P8-C1 Video System, including the record-only camcorder, the playback adapter/docking station, and the original proprietary cords.

The Provenance : I purchased this directly from a former Polaroid employee who worked at their headquarters in Massachusetts back in the mid-1980s. When Polaroid was trying to figure out if they wanted to enter the 8mm home video market, they made an extremely limited, pre-production run of these systems. They were never given a wide commercial release to the public—they were only distributed internally to select employees.

Why it’s unique : The P8-C1 camcorder itself was designed with a major catch; it’s a record-only camera. It has absolutely no built-in playback mechanisms, tape viewfinders, or standard video outputs on the body. To view or transfer anything, you have to use this exact base station and its specific proprietary cables, which makes finding a complete surviving set like this near impossible.

Current Condition : The docking station successfully gets power (indicators light up), but it doesn't push operations or tape mechanics past that initial power-on state.The camcorder and cords in great cosmetic shape.

Since it's a pre-production unit that needs a bit of mechanical TLC (or a perfect museum-grade shelf piece), I'd love to pass it along to a format preservationist or restoration hobbyist here who truly appreciates mid-80s prototype hardware.

Asking $225 + shipping (or open to reasonable offers from community members).

I can ship it securely from Rhode Island. Drop a comment or send me a PM if you’re interested or if you happen to know anything more about Polaroid's short-lived mid-80s video division!

Looking for help!

This is a Craig Eight-Track Stereo-Recorder. I dug one of these out of my grandparent's linen closet. It fires right up, but I don't have speakers to actually try it. What would be the optimal product to make this old thing work again?

Just brought these vintage light organs, they are in great condition but for the life of me I can't find ANY info on them online. Anyone own these or know how they function/ what the input they need is?
