The on-board computer for the ICARUS stratospheric balloon is almost ready for test. In this picture, you can see the stack of boards, including control, GPS and communications.
Another interesting project is undergoing within the UGRASP initiative. In this case, David Martín is doing reverse engineering with a test bench for small jet engines. In the pictures above, you can see some parts of the engine, the front panel and the main circuit board of the test bench.
