Motorola eval board
Alan's new eval board. I think it is a Motorola 68HC08. |
Modifing the board. |
It has this application builder thing. |
It works! |
UPS
Jeff got these APC 280S UPSs. This is what it looks like when you take it apart. |
This is the controller board. |
One assembled, one disassembled. |
Wen it is running it puts out this sqaure wave to approximate a sine wave. |
Normally it passes the AC directly from the wall outlet. |
Jeff is tracing out the driver circuit. |
Just for fun
Alan got this new keyboard. It looks just like a cat. |
