Software Release Button


Launching a ship is exciting! Maybe that ship is a rocket ship, or maybe it’s a traditional ship which floats in the water. When launching a ship there’s often a ceremony involving some champagne and pageantry and a party and it’s quite an event. (I’ve been to at least one boat launch, so I know what I’m talking about!)

When you launch a new version of your software, it’s not quite as exciting. I mean, it is, but in a different way. Sure, twenty years ago there was probably a lot of excitement around master discs and packaging and all that, but in 2019 with most software delivered as a service, it’s not much more than someone typing a few commands, clicking a mouse, and pressing the enter key. Not as exciting.

But! Some software company decided to make it exciting, and they asked me to help. They’ve now got a “Software Release Device” that they can connect to a computer, then turn the key to enable the device (which turns on a lamp letting them know it’s ready) and then they can switch between mouse and keyboard and hit the big read button to launch the latest version of their software to the world. Exciting!


They made it pretty easy for me, as they specified most of the parts for the build. The lamp was meant to run on 24VDC but luckily it was just a matter of cutting open the housing, replacing some resistors, and gluing it all back together to get it to run on 3.3VDC, and it looks really nice.

If you’re interested in some sort of custom USB device, let me know… I’d love to build something for you.
