    newbie question

    I probably have a 3v supply in the the shed somewhere. What value / rating would you suggest for the diode? Many thanks for the help Andy

    newbie question

    I was just looking for a cheap solution with the odd bits I have to hand, they are only to cheer the kids up in the cold winter nights, I have them spread out over the bushes in the front garden. If need be I will just connect them in series across a 9V power supply and hope for the best, but I...

    newbie question

    100 lights per set, 500 in total each set of 100 runs from one 600mAh battery ( for about 4 hours on a full carge ) My probem is simply that the UK winter does not give enough light to fully charge the batteries each day, hence my intention to boost this with a small charger.

    newbie question

    1) 5 sets of lights, 100 LEDs per set, single LEDs 2) to be light opperated using existing solar panel sensors to reduce cost 3) one power supply to run all 5 sets. Power supplies available - 5V, 6V, 9V & 12V standard plug in DC power supplies. various currents from 350mA to 2,000mA Current...

    newbie question

    Great advice, but I'm afraid I don't know what a regulator or voltage divider actually are. My knowledge of electronics is limited to a O level in physics 30 odd years ago. I can manage to put a resister on parallel to drop the current, or series to drop the voltage, but that is about the limit...

    newbie question

    I'm struggling to find a 1.5v supply online, is there a safe ( and cheap) way to drop down the voltage from a standard 5V / 9V / 12V transformer, as I have a box full of those. Its a long time since I did O Level physics, but would a resister in series to the load do it ? and if so, what...

    newbie question

    I will take it apart again tonight and have a look. From what has been commented above, no one seems to see a problem with connecting these units in parallel across the batteries and wiriing in a small power supply, as long as I keep the current down to below say 1 amp ? I'm not looking to...

    newbie question

    It does look like the solar panel is used as the light sensor, as there seems to be no spare wires to the front plate. I cant imagine it is very complex, it runs 100 led's and the entire unit, including battery & led's only costs £7.99 ( about $12 )

    newbie question

    I did consider that, but I was unsure if it would be safe to run it during the day, with the LEDs off without the battery as a "buffer "

    newbie question

    Hello folks, Please excuse what is probably a silly question, but I would rather ask silly questions than catch something on fire..... My wife has recenty purchased 5 sets of solar powered garden lights. These work fine when fully charged, but the UK winter does not give enough light to...
