Adding USB To A Keyboard The Way It Used To Be Done

The world of custom keyboards has over the years developed its work into an art form, as mechanical key switches meet USB-HID capable microcontrollers for a plethora of designs as individual as their creators. This was however not always the case, and from the days of 8-bit home computers onwards making a custom keyboard often meant taking a surplus one from elsewhere and adapting its matrix to suit whatever controller interface was at hand. [Julian Calaby]’s USB conversion of an Apple Extended keyboard may be unusual in this day and age and was probably a late example even 15 years ago when he made it, but it remains a glorious piece of bodge-wire hardware hacking at its finest.

The task at hand with this type of conversion is to cut the matrix PCB tracks and replace them with soldered wires to create the new matrix required. This can then be wired to the controller, which in [Julian]’s case came from a cheap USB keyboard. He added a small USB hub to allow for a pair of USB sockets where Apple had put an ADB socket, making for quite a decent older keyboard with an unexpected USB interface.

Now older and wiser, he has plans to revisit his old keyboard with a modern microcontroller board, and needs to revisit the matrix again and give the peripheral new life. We still like the original though, as it captures a moment in time when keyboard matrix hacking made sense, and reminds us of our own youthful hardware follies.

Paging through Hackaday past it’s a testament to the old-school nature of this board that all we can find are microcontroller-based conversions. That’s not to say that cutting up old ‘boards is out of the question though.

Hackaday Links: July 24, 2016

Right now HOPE is dying down, and most of the Hackaday crew will be filtering out of NYC. It was a great weekend. The first weekend in August will be even better. We’re going to DEF CON, we’ll have people at VCF West, and a contingent at EMF Camp. If you’re going to EMF Camp, drop a line here. There will be Hackaday peeps wandering around a field in England, so if you see someone flying the Hackaday or Tindie flag, stop and say hi.

Raspberry Pi’s stuffed into things? Not all of them are terrible. The Apple Extended keyboard is possibly the best keyboard Apple ever produced. It’s mechanical (Alps), the layout is almost completely modern, and they’re actually cheap for something that compares well to a Model M. There’s also enough space inside the plastic to fit a Pi and still have enough room left over for holes for the Ethernet and USB ports. [ezrahilyer] plopped a Pi in this old keyboard, and the results look great. Thanks [Burkistana] for sending this one in.

We’ve been chronicling [Arsenijs] Raspberry Pi project for months now, but this is big news. The Raspberry Pi project has cracked 10k views on, and is well on track to be the most popular project of all time, on any platform. Congrats, [Arsenijs]; it couldn’t happen to a better project.

A few months ago, [Sébastien] released SLAcer.js, a slicer for resin printers that works in the browser. You can’t test a slicer without a printer, so for the last few months, [Sébastien] has been building his own resin printer. He’s looking for beta testers. If you have experience with resin printers, this could be a very cool (and very cheap) build.

Anyone going to DEF CON? For reasons unknown to me, I’m arriving in Vegas at nine in the morning on Wednesday. This means I have a day to kill in Vegas. I was thinking about a Hackaday meetup at the grave of James T. Kirk on Veridian III. It’s about an hour north of Vegas in the Valley of Fire State Park. Yes, driving out to the middle of the desert in August is a great idea. If anyone likes this idea, leave a note in the comments and I’ll organize something.
