It is very simple as far as electronics go so don't feel the need to wait for me. I will make a guide on how to make your own soon (maybe a couple of months). I'm very pleased with the response to The Most Annoying Machine! I think the switches are on back-order from Farnell so there are probably a few people making their own :) Hackaday is a great blog and I read most of the entries so seeing another of my projects on it is very satisfying! The description by Brian Benchoff was great as well. I got the idea from another of my projects - Smart LED Juggling Balls. If you throw the box in the air and then switch it off, it will stay off. The accelerometer inside detects if the box is in freefall or being held in place. Yes, I am looking forward to The Most Annoying Machine Version 2!įeel free to ask me any questions and I will do my best to answer them.Īre you still reading because you want to know how to switch it off?! Fine. I would like to make a bulletproof version out of aluminum and tidy up the all the wiring. For instance, unless you live in the UK with a local Poundland that stocks the nuts and bolts, you will need to modify the sizes in the OpenSCAD file. There is nothing particularly complicated about it but you might need to modify some of my stuff. I would love to write a full guide on how to make this but I don't have time at the moment. The code and files for the laser cutter are are available on Github. I laser cut it from 3mm plywood at the Fablab in Strathclyde University (I'm a post-grad student there). The case was designed using a modified OpenSCAD file from Thingiverse. Fortunately I spotted this before making the case and left room for a big boost converter that takes the battery voltage up to what's needed for the switch. The astute reader will have noticed that's not enough to activate the switch. The whole thing is powered by 3x 18650 3.7v lithium batteries. It also reads values from an accelerometer (that maybe has something to do with switch it off!). The switch I used can only go one way but for this project that didn't matter.Īn Arduino Pro Mini is used to control the LEDs, buzzers and the switch. When you apply 24v it will move to its default position. An actuated switch (that cost me £13, the most expensive button I have ever bought) is the key to the project. Inside the box are some simple electronics, the component section lists them in detail. If it's successful you will be irritated by the end of it, and possibly a little amused.
