Bob over at Making Stuff didn’t want to purchase an expensive cable for his digital calipers, instead he decided to build it. A small 3D printed grooved part with a few connected wires is all that is needed to connect to the data output port of the calipers. A logic level converter is needed to change from 1.5 volt output of the calipers a voltage high enough for a solid
If you are looking to send some data or some audio over a fairly long distance wirelessly you can have a look at this very cheap solution if line of site will work. Iforce2d is using a very inexpensive laser diode and receiver to get the job done. This code is what does the heavy lifting as far as getting the data across the link.
If you enjoy table tennis this trainer might be a great next project. Thomas Mayer created this as his bachelor thesis project. Two Playstation CL-eye cameras are used to view the play area and track the ball. A project is then used to display game elements that the players can interact with to play many game scenarios. The game was created using VVVV which is a visual/textual live-programming environment for easy prototyping
If you have a laser cutter and looking for an interesting weekend project, this Laser Cut Bowl by Outfab might be just the thing. The design is very good at material usage since all of the parts are nested inside the overall cutouts. If you wanted to bang together a bunch of them I could see making a slightly different design that could be put together and act as a guide, then
Ben Heck and his team built this Mechanical Television. It uses holes drilled into a vinyl record which is spun with a light source behind it. A light sensor is then used to determine the amount of light that is reflected off the surface of the item that they would like to transmit. A complimentary rotating disk with a controlled light source is used to duplicate what the
If you are tired of reaching for your tiny volume control knob to adjust your music when using your computer look no further than these projects by Engineering Nonsense and DIY Perks. The top one uses a DIGISpark board and a rotary encoder to adjust the volume via USB and the one below uses a potentiometer to adjust the analog output of your signal feeding your amplifier.
Fans are great, check out this Star Wars AT-ST Walker Build!
