Goals: – constructions improvements: * excluding wood from the construction * taking the wind sensors as far from the building-wall as possible * addition of temperature sensor * minimizing of number of wires going form the box to the sensors (by taking pull-up resistors out of the box boundaries: near…
Today’s experiment goals: – to check if smaller 3×1.2V (3x3Ah) Ni-ME battery array will charge better than 4×1.2V (4x3Ah) and if it will be enough to keep the anemometer alive – to make order in the wires – to recheck voltages given by the solar panels Related experiments: Raspberry-pi: experiment…
PC-based scope SW (courtesy of Ronen) http://www.zeitnitz.eu/scope_en Photo-report This report is about how the scope worked for me when it was tried with wind-speed and wind direction sensors powered from Raspberry Pi’s 3V pins. Constellation: – One cable built from two: __ * Gold Plated banana plug to Small Test Hook Clip Cable. Test Probes IC…
Anemometer data is on the Web now: N/A HTTP server and direction resolver are added: Source Code Bill Of Material creation begun: BOM
Summary: – Power consumption was lowered by more rare reports through wi-fi and by disabling of HDMI interface. – In-currents are increased by addition of two more solar panels (250 mAh 1.25W each). Thus we potentially may have 4x180mAh + 2x250mAh = 860mAh or in watts 4x1W + 2x 1.25W =…
