Jelmer @ jelmertiete.com did a teardown on a cheap IP camera and also obtained the root password of it with the goal to investigate the security of such a devices. He writes: IP Cameras have become extremely cheap in the last couple of years. Mass production made the prices of...

Zach Fredin and Joe Burdo has designed an electronic neuron simulator to help educate students of neuroscience. NeuroBytes are tabletop electronic neuron simulators designed to help students understand basic neuroscience concepts. The platform consists of modular elements that can be...

Brian Dipert @ edn.com has done a teardown on Amazon's dash button and shows the parts inside. How much hardware was Amazon able to squeeze into such a diminutive bill-of-materials budget, or perhaps more accurately, how much are Amazon and its consumable-supplier partners...

TC-Engineering has documented their efforts to program a Spartan 6 FPGA using a DIY PCB. The hardware part and software are discussed on the link below. I’ve been thinking about building stuff with FPGA’s for a while, and usually get turned away because FPGA’s are considerably...

Many a times equipment at workstations remains switched on unnoticed. In this situation, these may get damaged due to overheating. Here is an add-on device for the workbench power supply that reminds you of the power-on status of the connected devices every hour or so by sounding a...
