    Need Help With A Charging System On A Motorcycle. Have Schematic

    The rectifier is simply two bridges. Get two bridges and I will show you how to connect them. Get 4 amp: http://www.ebay.com.au/itm/like/222064946217?limghlpsr=true&hlpv=2&ops=true&viphx=1&hlpht=true&lpid=107&chn=ps 5 of them cost $1.00 with free postage. They will need to be screwed down

    my solar charge controller circuit

    You can buy all these things on eBay for less than $20.00 They are far too difficult for you to even start to design.

    Instructions needed for 3D light squared kit

    A typically poorly designed Chinese project. All my boards can be assembled without any instructions because all the items are clearly marked.

    Photoflash capacitors and Charging

    You need to see the coil gun article where you put a projectile in the barrel and fire it at a person and it kills them immediately. A really fun project.

    PIC 12F675 PULSE COUNTING

    Use 1 sec or more to prevent false triggering. You are much better to accumulate.

    I need assistance on one way transmit

    The output of the 555 drives a transistor that is configured as an oscillator and it gets a pulsed signal. The output of the transistor can be detected up to 200 metres. The output of the receiver will be a tone and this is picked-off the speaker to illuminate a LED.

    Charging lead acid battery

    The 13.6v "floating charge" or "floating voltage" produced by the battery will oppose the 13.8v and almost NO CURRENT WILL FLOW. (maybe 50mA) - certainly not 2 amps. You need to have more than 13.8v "up your sleeve" so you can charge at a decent current and then stop the charging when the...

    Charging lead acid battery

    "You need a power supply voltage of at least 13.8V to charge a 12V lead acid battery." 13.8V will give you no charging current.

    Remote Control - The Right Way To Fix It

    This is from an electronics expert: "Try measuring the voltage across the IR LED (preferably using an oscilloscope, but a DMM will probably suffice). If it changes when you press any button on the remote then that suggests a dead LED."

    Combine 2 power of units to equal 1?

    Connect them together and put a red LED between the two positive leads. Reverse the LED. If it glows, you definitely CANNOT

    Coil problems...

    To check the resistance, cut 1 metre of wire and connect it to the terminals of the battery in your car. Hold it with pliers and watch it glow red and go up in smoke.
