Antique Beat Box Showcases 1950’s Engineering Prowess

Before you could just put a drum machine app on your phone, or fire up Garage Band, there were breakthroughs like the Roland 808 drum machine. But that’s not where it all started. In 1959 a company called Wurlitzer (known for things like juke boxes, pianos, and giant pipe organs) produced a new device that had musicians worried it would put drummers out of a job: The 1959 Wurlitzer Sideman. And in the video below the break, we have the joy of watching [LOOK MUM NO COMPUTER] open up, explain, and play one of these marvelous machines.

Can you spot the early circuit sculpture?

It’s noteworthy that in 1959, almost none of the advancements we take for granted had made it out of the laboratory. Transistors? Nope. Integrated Circuits? Definitely not. What does that leave us with? Vacuum tubes (Valves for those across the pond), resistors, capacitors, relays, and… motors? Yep. Motors.

The unit is artfully constructed, and we mean that quite literally- the build was clearly done with care and it is easy to see an early example of circuit sculpture around the 3 minute mark. Electromechanical mechanisms take on tasks that we’d probably use a 555 for these days, but for any of you working on mechanical projects, take note: Wurlitzer really knew what they were doing, and there are some excellent examples of mechanical and electrical engineering throughout this primordial beat box.

If you move to the beat of interesting drum machines, you might enjoy this Teensy based Open Source drum machine that you can build. No tubes required!

Hackaday Links: December 1, 2013

Since our ‘ol buddy [Caleb] left Hackaday for EE Times, he’s been very busy. One of his latest projects is doing Antique Electronics Autopsies. This time around it’s a 1953 Heathkit Grid Dip Meter. It’s a beautiful piece of engineering with Point to Point wiring and metal gears.

We love microcontroller breakout boards, and so does [Tim] apparently. He built a breadboard friendly breakout for the NXP LPC812. It’s an ARM Cortex M0+ with 16kb of Flash and 4kb of SRAM. The entire breakout board is smaller than the through-hole DIP LPC1114. When are we going to see these on Tindie, [Tim]? Here’s the Git with the board files. You can also pick up a board at OSH Park – $3.30 for a set of three.

What do you do when you have the perfect idea for a Kickstarter, but don’t have the funds for the perfect sales pitch? The obvious solution is to start an Indiegogo campaign to raise funds for your Kickstarter. Unfortunately, this campaign has already been successfully funded, so it’s already too late to get in on the ground floor. Relevant xkcd.

We’ve seen this DIY cell phone before but now it’s just about ready for production. [David] at the MIT Media Lab has been working on a bare-bones, ATMega & GSM module phone for a while now, and now you can grab the firmware and board files. Make your own cell phone!

Here comes Hanukkah, so drink your gin and tonica. Here’s a pedal powered menorahica so put on your yarmulke, it’s time to celebrate Hanukkah.
