Between the recent office move and keeping up with herds of cats, I’ve fallen a bit behind in reporting news in other areas. Work is still progressing on the Ultracap power supply. After some further testing of the cell-balancer circuit based on the TI TLV4112IP high-output-drive op-amp, I decided that, while working flawlessly otherwise, it [...]

Ultracap Update After prototyping a cell-balancing circuit for my robot power supply based on Maxwell 350F Ultracaps, I discovered the original choice of the TI TLC25L4CN low-voltage op-amp was not a good one. The little chip just couldn’t deliver enough current to balance the cap voltages in any reasonable amount of time. The peak output [...]

At the DPRG RBNO last night, I worked out the basic design for my robot power supply with the help of a few other DPRG folks. The plan is to use 4 of the Maxwell 350F caps to store power from solar cells. (Someone was asking about the cost – the single unit price of [...]

I mentioned in my last entry that I’d been experimenting with the Not Quite C programming language for use with the Lego Spybotics brick. The hardware hack we made for line-following combined with a few lines of NQC code allowed one of the robots to successfully complete the line following course at Roborama 04.A (it [...]
