    batteries

    I want to buy rechargeable batteries and found these- http://www.allelectronics.com/cgi-bin/category.cgi?-125&type=store I think this charger will work, but I wanted to get some input before I buy them. charger- http://cgi.ebay.com/ebaymotors/12-Volt-Battery-Tric Is there anything I should...

    boost converter

    Yeah, it's fixed.

    boost converter

    Yes, the one I meant was connected to pin 2. I bought a breadboard and used this for as many parts as possible.

    boost converter

    I tried it but it didn't work. Was the ground from the timer supposed to go to the back of the transistor? I have a circuit layout from someone else who built a boost converter, but am unsure of one of the components he used. The diagram for the boost converter does not show it. Could you...

    boost converter

      Is there a way to change the 100k resistors to lower values? The most I have are 20k power resistors.   I am connecting the 555 timer output (+) to the back of the transistor and the (-) to the left pin. The center pin is connected to the output side of the inductor. The right pin is...

    boost converter

    Part of the problem I am having is not being sure if I am connecting things to the switches the right way. I will try the circuit you provided and see if it works.

    boost converter

    I've been using 3 different kinds: 400V 8A NPN transistor TO-220 case       http://www.alliedelec.com/cart/ProductDetail.asp?SKU=568-4088&SEARCH=MJE13007&ID=&DESC=MJE13007 ***This one is the only one that will get to 30V, the other two reach 20-25V*** 500V 14A Field Effect N...

    boost converter

    I need to see if I am connecting the leads to the right pins. For some reason it will only oscillate to 30V.

    boost converter

    Just realized what you were asking. I meant the pins on the IGBT or transistor.

    boost converter

    The pin numbers aren't the problem, I can build the 555, but the switch I'm using won't oscillate. It only boosts until 30V, with either the boost converter or transformer. I'm not sure if the equipment I'm using is wrong or if I don't know how to operate the circuit.

    boost converter

    I have it soldered together with wires, but I can't get the switch to oscillate. I have tried it on the boost converter, the converter using the transformer and a flyback driver. Could you give me a diagram showing me how to connect the boost converter driving circuit (what wire goes to which...

    boost converter

    I don't think I've figured out how to build and/or use the driver yet. Will someone explain how to assemble it and operate it?

    boost converter

    the battery wasn't connected when I measured it. The charger is only giving me a 2-3 V charge when I use just the transformer. Any ideas??

    boost converter

    I think that the wall converter should work, but I have one question. The side that was origionally plugged into the wall and is now my secondary doesn't register with the continuity test on my DMM, but it does conduct when I connect a battery. When the DMM is connected it registers .5 on the...
