Yes there is a cooling fan. and yes I really do have a 55 farad cap. Charging is with a bicycle generator, although this is nothing to do with the interference as I've tried it disconnected. To give you an idea: http://www.youtube.com/watch?v=_UK0noZrDC8&feature=player_embedded thanks colin

Hi I need help with a project. I have a 16v 55Farad capacitor that I am using to run a small 50 watt DC projector and 10 watt guitar amp. The audio is provided directly from the projector. Everything is DC. Both the projector and amp are connected directly to the capacitor. The problem with...

One other question: If the voltage is going to continue to rise is this going to blow a bunch of 12v bulbs?

Hi vk6kro I'll take a look at the chip thanks. Ah so what you are saying is that as the wattage increase and the resistance increase, hence the voltage will increase and this can be measured? I might be able to get a hold of a relay driver like this one...

Hi Well I'm back again with as usual more questions that answers! Ok I would like to build to following as an educational tool: The generator is MY1016 DC PM motor that can produce upto 200watts connected to a child's bicycle. Kids around 10 or 11 should be able to do a 40watts burst...

Thanks 'sophie'! I think you are absolutely right, especially given my limit to no experience in this area! I'm going to follow up on the lead that you have presented here and want to say thanks to everyone! I'll keep you informed!

Thanks everyone for your comments! I am amazed just how much information you have provided in such a short amount of time. Sadly, I am well out of my depth (as Aduster alluded to) and don't really understand how all you comments summarize into a simple circuit. You were all correct about the...

Hi, I am wondering if you can help: I have a hub dynamo that I would like to use to charge my mobile for a cycle ride across europe. The DC hub dynamo produces anything up to 40volts at full pelt! So I want to use a car charger to charge my mobile phone (and one for a camera), which I...

Yeah they are an excellent motor, well built and made from decent metal! Bob I was wondering, do you think http://uk.rs-online.com/web/search/searchBrowseAction.html?method=getProduct&R=2278621" would suit? Really appreciate your help. You'd think after powering an entire house with these...

Ah I see, the motor we are using is this http://www.monsterscooterparts.com/24v30mowisp.html" . To answer your question regarding generating electricity! Yes, we believe it or not we used them to do http://www.bbc.co.uk/programmes/b00p8469" ! Look forward to your reply. Thanks Colin

Thanks Bob, I just had a look at a http://upload.wikimedia.org/wikipedia/commons/1/13/4_diodes_bridge_rectifier.jpg" for a bridge rectifier and it does make perfect sense! Thanks-you. ps the motors are brushless but I suppose that makes little difference?

Hi, I have a 24v 250w PM DC motor that is being used generate electricity. Problem is that the way it is installed, it can be turned in either direction which of course gives me a polarity problem. I'm sure there is a simple solution, but could someone tell how I maintain a constant...

Thanks everyone for making that very clear. Have a couple of other questions if oyu don't mind regarding charging capacitors and batteries from DC generators: So I have a DC generator connected to a 15v 52F ultracapacitor. There is a diode in place. If the generators has in inherent 1.7ohm...

Hi have a question: When I connect a PM DC generator to an ultracapacitor and begin charging the ultracapacitor is there more resistance from the outset with the resistance dropping proportional to the voltage? Thanks Colin

there is a diode on the + side of each generator to prevent the current of one motor driving the other. The three groups of four motors join together. Here is a rough diagram that I hope you can make sense of (attached) thanks colin
