Class Update

The projector came in and I rearranged the room again. The good news is that it is a 1024x768 resolution unit. I scrounged around and found a 6 or 8 foot projection screen.
For the first time I can let the students watch me demo code. I plan to use a small USB cam to show the Junebug in action as I step through code.
It has been a bit of a battle to get enough Junebugs built and running. I started on a batch of 6 prior to school starting. 4 of the 6 came out OK. On one I had a LED in upside down (duh) which was easy to fix. The last has some problem with the target A1. It is shorted to another trace and it loads the system to where VPP does not come up. The short is not to ground or VDD.
I sent the Junebugs home with the kids this weekend mostly to get them used to the idea that they can be used at home. The students without laptops will need to install software on their system.
One student has a USB port that causes the 18F2550 to need a OS reload every time he inserts the plug?
