Resurrecting An Amiga CD32

As an editor on Amiga magazines in a previous life, this is kind of bittersweet. [RetroManCave] was donated an Amiga CD32 games system, and it is trying to resurrect it. If you’ve not heard of it, the CD32 was a 1993 games console based on the Amiga home computer system. It was the last gasp for Commodore, the beleaguered company behind the Amiga. In this first video of a series, they take the system apart, take you through what’s inside and boot it up. The system boots, but there is some sort of problem with the video sync, and they …read more http://pje.fyi/QGlZYT

Curing a Parrot’s Amnesia with BLEAH

[Dandu] recently wrote in to tell us how he managed to revive his Parrot Flower Power after the manufacturer told him it couldn’t be repaired. To save you the trouble of opening Google in another tab, the Parrot Flower Power is a Bluetooth Low Energy (BLE) “smart” device for your flower pot. Because of course that’s a thing.

When [Dandu] noticed his Flower Power was no longer being detected by his iOS devices, he contacted support who told him that sadly this was a hardware failure and that he should just throw it away. But he had his doubts about …read more http://pje.fyi/QFn8gX

Vintage Logan Lathe Gets 3D Printed Gears

In December 2016, [Bruno M.] was lucky enough to score a 70+ year old Logan 825 lathe for free from Craigslist. But as you might expect for a piece of machinery older than 95% of the people reading this page, it wasn’t in the best of condition. He’s made plenty of progress so far, and recently started tackling some broken gears in the machine’s transmission. There’s only one problem: the broken gears have a retail price of about $80 USD each. Ouch.

On his blog, [Bruno] documents his attempts at replacing these expensive gears with 3D printed versions, which so …read more http://pje.fyi/QB6PKy

60’s Comedy Rescued from Nigerian Basement

In the sixties, videotape used to film television programs was expensive. When a program had been shown as many times as the contract required the tape was wiped and reused, unless someone requested it be saved for some reason. At least, this was the BBC’s doctrine. Many episodes of the BBC’s programs have gone missing due to this reuse of the videotapes but sometimes the films of these episodes are found in an attic or storage facility. [Cplamb] brings us the story of the salvation of some episodes of British comedians Morecambe and Wise’ first series on the BBC, their …read more http://pje.fyi/Q8Z1QL

Custom PCB Revives a Vintage Tree Stand

After 56 years, [Jeff Cotten]’s rotating Christmas tree stand had decided enough was enough. While its sturdy cast aluminum frame was ready for another half-century of merriment, the internal mechanism that sent power up through the rotating base had failed and started tripping the circuit breaker. The problem itself seemed easy enough to fix, but the nearly 60 year old failed component was naturally unobtanium.

But with the help of his local makerspace, he was able to manufacture a replacement. It’s not exactly the same as the original part, and he may not get another 56 years out of it, …read more http://pje.fyi/Q8V5jj

Get Down to the Die Level with this Internal Chip Repair

Usually, repairing a device entails replacing a defective IC with a new one. But if you’ve got young eyes and haven’t had caffeine in a week, you can also repair a defective chip package rather than replace it.

There’s no description of the incident that resulted in the pins of the QFP chip being ablated, but it looks like a physical insult like a tool dropped on the pins. [rasminoj]’s repair consisted of carefully grinding away the epoxy cap to expose the internal traces leading away from the die and soldering a flexible cable with the same pitch between the …read more http://pje.fyi/PvjWKz

Space Technology and Audio Tape to Store Art

[Blaine Murphy] has set out to store an archive of visual art on cassette tape. To do so he encodes images via Slow-Scan Television (SSTV), an analogue technology from the late 50s which encodes images in for radio transmission. If you are thinking ‘space race’ you are spot on, the first images of the far side of the moon reached us via SSTV and were transmitted by the soviet Luna 3 spacecraft.

Encoding images with 5os technology is only one part of this ongoing project. Storage and playback are handled by a 90s tape deck and the display unit is …read more http://pje.fyi/PvfGRQ
