This project by newtonn2 is a nice DIY Small Bench Power Supply. I like the case design which is lettered with the toner transfer method. Great looking results. “The heart of the unit is basically the same as on the other power supply. It is based on the LM2596S. This IC can handle up to 3A with a good heat sink. I would use it only for 2A to
Mike Harrison from Mike’s Electric Stuff shows off how he used a small thermal imaging sensor and incorporated it into a custom little project with a iPod Nano screen. With a tiny bit of polish this thing would be a great product on any hardware store shelf!
If you need some computing power on the go you might want to look into adding a car computer. Sentdex shows us how he does it on the cheap, the top of the great find is the $17 monitor. It has a Raspberry Pi as the heart, an ODB interface and a camera to loop record. An interesting power management system allows the system to detect when car power
I will need to give this a try one of these years. CNC Pumpkin Carving creates some great looking results!
 In this DIY Electronic Fish Feeder an Arduino microcontroller is used to spin a drill bit which is placed to work as an auger to meter out fish food. If you want to build you own Brian goes through the build step by step.
If you need to crush a bunch of aluminum cans you might as well build a machine to do it. That is what we see on the Ben Heck Show here. After Ben bent through a bunch of design submissions a cool design was selected. A single stepper motor crushes a can with a 30 to one gear reduction it can crush the can but isn’t able to crush
  Check out the F*watch! It is a Free Fun Flexible Watch design by a team of 15 people with various backgrounds, the watch is a challenging project since in the end it can’t be the size of a lunch box, can’t weigh a pound and can’t be plugged into the wall for power. All of the electronics fit into a tiny printed housing and looks very functional. Check
