====== PicoAtlas VIII ====== ===== Components ===== * pAVA R7 board with linear regulator * Atmega328 * Rfm22b * Ublox 6 * 2 x AAA * 2 x 3.7v 100mA solar cells in parallel ===== Launch 1 ===== * Launch 1 was on 15/12/12 - unfortunately on releasing the payload it did not have enough lift resulting in it dragging across the fields and getting caught in a tree 2km away, max altitude was 101m. Was recovered the next day (still transmitting). ==== Lessons ==== * Need to launch Pico's in ideal weather, from now onwards I plan to only launch in: * Ground windspeed < 8km/h * < 50% cloud cover * no rain or forecast rain * Need to take in to account that lifting gas might cool once outside and lose lift, may require a little more gas before launch.
