The invention no-one cares about
So SheCharger abandonned quick charging, lost her MOSFETS, thermistors, & heatsinks. She now supplies constant 0.05C to 5 D slots & 11 AA slots. No more applications require quick charging NiMH. Her biggest problem was the analog levels changed depending on the number of batteries being charged so she couldn't tell what batteries were connected. Now she charges full time and the LEDs are decorative.
Now thinking of starting the fixed wing phase sooner, since copters R going to have lots of downtime. Components & current prices for the fixed wing phase Code:
Single IDG300 for roll & pitch. Free ADXL330 for gyro drift. $35 uBlox for heading, speed & position Free XBee communication $32 Easystar airframe $60 PIC18F Free Prototyping $20 Motor + ESC Free Shipping $30 The goal: single chip autopilot to reach high altitude, long duration, long distance, take a picture, & return. The plan: upgrade PIC bootloader to flash a complete autopilot from the serial port. Single chip autopilot firmware in C. Board bringup before airframe purchase. |

Are you looking at another platform for Vica II, or are you going to use a Corona?
Matt Shumaker makes a ton of parts for the Corona here: Ballistic Technologies Parts list of some of the things he makes: Parts list |

Fixed wing is sort of a been there done that problem. Helicopters are a much harder problem and you were making dang good progress. Good luck, Reed Quote:
