There are times that I need to reprogram an embedded system. Usually I have to crack open the laptop, a serial communication device, and hook everything up just to download a new or updated program into the device.
And if anything goes wrong its catastrophic!

At the moment, it is mostly working hardware and the operating system is setup as a hardware test rather than a user friendly operating system.
Here is a few photos of the start of this project;
