The Cassette MP3 Player

cassette

1994 was twenty years ago. There are people eligible to vote who vaguely remember only one Bush presidency. You can have a conversation with someone born after the millennium, and they think a 3.5 inch disk is called a save icon. Starting to feel old? Don’t worry, all the trinkets of your youth have now become shells for MP3 players, the cassette tape included.

[Britt] is aware you can pick up one of these cassette tape MP3 players through the usual channels, but she wanted her build to be a little different. She’s using ar real, vintage cassette tape for starters, and from the outside, looks pretty much like any other cassette tape: there’s a thin strip of tape at the bottom, and the clear plastic window shows the tape is at the beginning of side A.

Outside appearances are just that; inside, there is a small, repurposed MP3 player, with tact switches wired up to the old buttons, actuated by moving the spools back and forth. Yes, you actually play, pause, rewind and fast forward by sticking a pencil in the spool and moving it back and forth. Amazing.

It’s a great build, and considering both cassette tapes and cheap MP3 players can be found in the trash these days, it’s something that should be hard to replicate.

Tape decks are fertile hacking ground. In this offering from [Erich] the speed of the motor has been turned into a MIDI instrument. Drive it faster and the pitch rises, slower and it falls. There are all kinds of other magnetic tape hacks around here, this tape delay is a classic.

[Dbever] needed a reason to use a big 7-segment display module. He opened up the drill press at his Hackerspace, Pumping Station One, and added a sensor which shows the RPM of the drill on the display. Hackaday was lucky enough to be invited for a tour of the space last fall.

There’s a lot of hype about 3D printing… and rightly so since it’s the radest; which is even better than being “the most rad”. But if you don’t have access to one that shouldn’t stop you. Here’s an example of making robot parts using polymorph instead of 3D printing (or laser cutting) them.

If you’re living in the east-coast metroplex and are unable to travel to Maker Faire Bay Area this Spring you can still get in on some live hacking. Check out MassHack which takes place the same May weekend but in Boston instead of San Fran.

Blimps; not as cool as quadcopters but orders of magnitude less likely to go down in flames (as it were). Draw some inspiration for your own build from silent_runner. The graceful travel of these lighter-than-air-craft make for an interesting camera platform. Here’s a POV video inside of a church, and some shots from the ground while in the woods. [Thanks Oliver]

We try not to pimp crowd-funding campaigns just for the sake of getting them to the goal. But we hope you’ll agree that the Gamebuino we saw a few months back makes a strong argument for backers. Their Indiegogo for the Arduino-compatible handheld gaming rig is over half-way there after just a couple of days.

Most useless machine

We love ‘em, and we hope you do too. Here’s [Phase2plus'] take on the most useless machine.

Scratching like it’s 1989

[Nick] spent three bucks at the thrift store and ended up buying days worth of fun with this cassette player. He hacked it to scratch like vinyl.

3D printed jawbone

This lady now has her own 3D-printed jawbone. We’re not talking about the Bluetooth headset… it’s an actual bone replacement! And yes, the skeleton for the Terminator was 3D printed… we’re that much closer now. [Thanks Steve]

Hexbug superbowl

Why not let robots decide our sports gambling choices? [Eric] let this slew of HexBugs battle it out as an early indicator for who would win the Super Bowl. Seems he has no shortage of the little toys, all of which received an MSP430 upgrade. The firmware actually implements obstacle avoidance, but he makes a poke at the Chicago Bears who seem to have the same mission.

Foil fix for worn out remotes

[Viktor] found an interesting repair tip. If you’ve got remote controlers whose buttons are not working so well anymore you may be able to fix them with tin foil. He uses a single-hole punch to clip out circles which are attached to the underside of the misbehaving button. Worth a try!
