Relay Computer Starts with an Adder that Makes a Racket

Posted on by

Computers built using discrete logic chips? Seen it. Computers from individual transistors? Impressive, but it’s been done. A computer built out of electromechanical relays? Bring on the ozone!

The aptly named [Clickity Clack]’s new YouTube channel promises to be very interesting if he can actually pull off a working computer using nothing but relays. But even if he doesn’t get beyond the three videos in the playlist already, the channel is definitely worth checking out. We’ve never seen a simpler, clearer explanation of binary logic, and [Clickity Clack]’s relay version of the basic logic gates is a great introduction to …read more

Pick-And-Place Machine for Candy

Posted on by

Every December and May the senior design projects from engineering schools start to roll in. Since the students aren’t yet encumbered with real-world detractors (like management) the projects are often exceptional, unique, and solve problems we never even thought we had. Such is the case with [Mark] and [Peter]’s senior design project: a pick and place machine that promises to solve all of life’s problems.

Of course we’ve seen pick-and-place machines before, but this one is different. Rather than identifying resistors and capacitors to set on a PCB, this machine is able to identify and sort candies. The robot — …read more

Script Your Way Out Of Video Editing Drudgery

Posted on by

[Victor Frost] has a deep voice and a fancy top of the line camera. While one would assume this to be a more than generous situation for life to put a person in; it’s got its own set of problems. Mainly that his fantastic fancy camera uses the most modern version of the popular h.264 encoding scheme, h.265. Gasp!

While that too seems like a pro, unfortunately h.265 doesn’t play as nice with his editing software. The solution seems easy, just transcode it and get on your way. However, when you start talking about transcoding 4K video from a top-of-the …read more

Hook Any Mouse to an Acorn

Posted on by

Acorn was one of the great IT giants that rose high and then fell to obscurity during the rise of personal computing. However, for many hobbyists these computers are as important and as loved as the Commodore 64. [Simon Inns] has made a great adapter to interface modern USB mice to these old boxes. 

After thirty years of interaction with people, one might be hard pressed to find a working mouse for an older computer. On top of that, even if you did, these mice are likely a lackluster experience to begin with. They were made long before industrial designers …read more

Microcontrollers now substitute for CPUs

Posted on by

Microcontrollers are getting faster and faster, as is most of the rest of the computing world. Just like you can play Nintendo console games on the newest Nintendo handhelds, it seems that modern microcontrollers can replace CPUs on personal computers from the 80s. At least, that’s what [Dave] has shown with his latest project: an Atmel microcontroller that directly attaches to the CPU slot on a Commodore PET.

Essentially, the project started out as a test rig of sorts for the Commodore. [Dave] wanted to see if some of the hardware on the Commodore was still functional and behaving properly. …read more

Staying In and Playing Skyrim Has Rarely Been This Healthy

Posted on by

Looking to add some activity to your day but don’t want to go through a lot of effort? [D10D3] has the perfect solution that enables you to take a leisurely bike ride through Skyrim. A standing bicycle combines with an HTC Vive (using the add-on driver VorpX which allows non-vr enabled games to be played with a VR headset) and a Makey Makey board to make slack-xercise — that’s a word now — part of your daily gaming regimen.

The Makey Makey is the backbone of the rig; it allows the user to set up their own inputs with electrical …read more
