    donkey's diy

    Just thought I would post something I have found and hope others add to it as they find out more Recently I built a small rc tank (it worked for a bit then died, i didn't realise the motors were too hardcore for the board) the custom build controller had an analogue joystick bought from a place...

    Call it feed back.

    this is actually quite ironic. I was just about to post on a similiar topic. As yet I have not found any harshness, but there are times when I feel like my questions are from a 2 year old not a 30 year old. I too am a hobbyist, but have aspirations to find that gimmicky device that will one...

    solar

    yeah i get all this slowly. but I wish I could get a calculator made to make this easier lol. it'd be real cool if it somehow calculated the average hours of sunlight (from both sunrise and sundown, and from how much rain you got for the past year averaged out) to accommodate a pretty accurate...

    solar

    well so far the loads are simple, 75w ryobi battery charger. a 25watt soldering iron. later on maybe a power saw and jigsaw. and a light or 2. this is more a reference for me when I get of my lazy butt so i can come back and review... oh wait, mongrel your on the goldie.... will just pm you to...

    special switch plate

    its nothing with a trademark, its for charity so no need for privacy on this one. that pic i linked to has sections I am going to cut out perspex or accryllic to make the panels. I am thinking of putting them between 2 panels. the first panel will have holes for the push button switches they...

    solar

    I am hoping people can correct my errors on the following information in the hope of getting a better knowledge So far I know the basics. in all systems it is best to have 3 parts. the panels, the battery and a charge controller. So far my research suggests that a 1:1:1/4 ratio is needed that...

    special switch plate

    I am thinking this is a weird one for everyone but I have to ask. the switch I think is fine (simple push on push off) but am trying to make a face plate for them. we have a variety bash car done up as bumble bee. I was thinking how can we make it more autobot...ish. so I decided on making the...

    Circuit diagram help

    personally I would downgrade this to a 12volt application. the maths side is not my strong suit so will leave that to others. as for overwhelming.... well it can be. I found the easiest way of doing things is finding people in the know with a few minutes and ask them questions, show them what I...

    Circuit diagram help

    ok first of all I can't think of any reason this shouldn't work on 220volts BUT I would not play with at a beginners level. If you are trying to figure out AC voltage get a starter motor from a car(these things hurt too but are a bit safer) or even a hand dynamo (they range from 1.5v up to...

    solar

    hey people getting into arduino is getting fun, but the cost of battery packs is starting to get high so was looking at the solar alternative. the issue is as always how to do it RIGHT I was thinking of plugging the solar panels straight in but in low light or at night that wouldn't be an...

    Got a question about driving LEDs? (Another work in progress)

    trying to get specs or data sheet of the seller. but at 12v is that the recommended resistor value?

    Got a question about driving LEDs? (Another work in progress)

    http://www.ebay.com.au/itm/150716639202?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 for led's like these if i wish to drive them will I hook a resistor to each cathode? I am just unsure about using the multi colours at once, are they like 3 leds in one? or is it all together and is the...

    School Project: Robot Vacuum Cleaner

    or a secondary system that beeps when the battery is low so you can find it to put on charge, and also doesn't drain the battery of the vaccuum/ motor servo

    School Project: Robot Vacuum Cleaner

    as this is homework in essence I can't add too much, but an observation with your mind map is that there is no discussion on power. if running from mains then chords can get tangled. if on battery when does it self charge? will this affect the timer? as its indoor use I am assuming solar will...
