Dobson dreams


LCROSS is heading towards a very large, motorized, Dobson mount, which can be bolted together in the field & stored for a human amount of rent. The mane problem is finding suitable bearings.

There it is. Our 2nd USB gadget is the bitbanger. It converts USB to 7 logic signals. Its purpose is a universal PIC, Atmel, JTAG programmer. For the PIC, U need a glue circuit to get 9V. For Atmel, U need a bag of resistors to lower the voltage.

We've been using the parallel port programmer since 2005. After 1 year banging on TTL chips, 3 years banging on 68HC11's, our first PIC gadget was HeroineClock using a PIC16f877. It now grinds away for 10 minutes on VikaCopter's firmware & more gadget needs keep coming.

Most of U implement USB or XBee bootloaders. With the number of gadgets & different communication methods we're using, that would mean implementing a new bootloader for every gadget.
