PiSound, The Audio Card For The Raspberry Pi

Kids today are being loud with their ‘drum machines’ and ‘EDM’. Throw some Raspberry Pis at them, and there’s a need for a low-latency sound card with MIDI and all the other accouterments of the modern, Skrillex-haired rocker. That’s where PiSound comes in.

Of course, the Pi already comes with audio out, but that’s not enough if you want to do some real audio processing. You need audio in as well, and while you’re messing around with that, adding some high-quality opamps, ADCs, DACs, and some MIDI would be a good idea. This is what the PiSound is all about. …read more

Raspberry Pi-Based Game Boy Emulator

The most popular use for a Raspberry Pi, by far, is video game emulation. We see this in many, many forms from 3D printed Raspberry Pi cases resembling the original Nintendo Entertainment System to 3D printed Raspberry Pi cases resembling Super Nintendos. There’s a lot of variety out there for Raspberry Pi emulation, but [moosepr] is taking it to the next level. He’s building the smallest Pi emulation build we’ve ever seen.

This build is based on the Pi Zero and a 2.2″ (0.56 dm) ili9341 TFT display. This display has a resolution of 240×320 pixels, which is close enough …read more

A 3D printer and laser cutter were cited as cause in two deaths. A couple (and two cats) were found dead in their apartment this week. The cause of death was carbon monoxide poisoning. Police and the gas company investigated the residence and found no other source of carbon monoxide besides a 3D printer and a laser cutter. Be sure to check out the people who know more about these deaths than the people who actually investigated these deaths in the comments below. In the mean time, get a CO detector. It’s nasty stuff.

At CES last this month, Lulzbot …read more

What is a 1971 Ford Torino worth? It depends, but even a 2-door in terrible condition should fetch about $7 or $8k. What is a 1971 Ford Torino covered in 3D printed crap worth? $5500. This is the first ‘3D printed car’ on an auction block. It looks terrible and saying ‘Klaatu Varada Nikto’ unlocks the doors.

Old Apple IIs had a DB19 connector for external floppy drives. Some old macs, pre-PowerPC at least, also had a DB19 connector for external floppy drives. These drives are incompatible with each other for reasons. [Dandu] has a few old macs and …read more
