Reviewed by Editor: Jack Allison HW Components: – Arduino/Funduino Pro Mini (ebay). It comes without programming related HW on it (as at other Arduino products), but pre-programmed with boot-loader. The boot-loader allows to upload new code to Arduino Pro mini without the use of an external smart hardware programmers, but just using…
Goal: Learn using RF 433Mhz with SMAKN Amplitude-Shift-Keying Tx/Rx Kit Components: – SMAKN 433MHx Transmitter and Receiver modules (ebay) (scarce data is downloadable) – RPi and its GPIO pins – Tool: http://www.zeitnitz.eu/scope_en described also here Wiring: SW: – Virtual wire from here by abyz with a bug fixed by me (the tx…

Goals: – improvement of rotation easiness of the dynamo by oiling with WD-40 – improvement of the dynamo sensitivity to winds by widening of the blades’ effective area – checking of the dynamo voltages and currents – activation of logging mechanism to be able to analyse the dynamo behavior knowing wind speed…
Goal: To try to get some power from the wind using Shimano Nexus HB-NX50 dynamo hub (power modulator) Conclusion: The dynamo hub is too tough to get rotations from weak winds. No rotations gotten so far with the blades made from dog-food cans. Pictures:
Goals: – Raspberry Pi based Anemometer: to provide a capability of electrical restart w/o opening of the case. – To try to launch PCDuino and Odroid boards that arrived long time ago – To work on new solder iron’s US-plug and to make it EU-compatible. – To take my old MIO Pocket…
Goals: – to accomplish the anemometer assembling and to connect it to the sensors prepared earlier – provide additional 5V DC power source for the times when development is done; this power source will also eliminate the need to unseal the box for batteries recharge; this power source is planned to be removed completely after the…
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…
