Kevin and I put together a little arduino circuit to control the solenoid in a valve we have for a project we are working on. This video explains what we have done and hints at why.
Here’s a brief synopsis of two projects currently underway.
Ron is leading the construction of a CNC router. A workpiece will rest on two platforms, salvaged from a defunct laser cutter, and stepper motors will drive them in the X and Y-axes. Another stepper motor will move the a router up and down in the Z-axis from a mount above the work. When complete, the device will be able to produce 3-D objects out of wood and some light metals. So far, the two heavy platforms have been installed on a wooden frame and Ron is busy working on a carriage that the router will mount to so it can travel in the Z-axis.
Here we see Adam testing his latest creation. Using an Arduino board, he has built a device that registers a ‘hit’ whenever a magnetic pellet strikes a sensor. The ultimate goal is to build a vest of sensors, lights, and buzzers that airsoft enthusiasts can wear. Whenever a gamer is shot, it will light up and make noise. Other possibilities include real-time score keeping and ways of recording who shot who, where, and how often during games.
More next time!
