    Increase output voltages from 4060B

    He has stated in another forum he has LED's on the outputs with no current limiting resistors. He has been told this will clamp the output voltages at the Vf of the LED's.

    FYI: The person posting in the general forum under the name Davewalker5 has previosly been banned from this forum and several others, using names such as Billy Mayo, Van Castillo, Danny Davis, Simmon and others. He keeps returning to forums with a new user name. The schematics he posts pictures...

    Uh sorry, I just noticed there is a mistake on that schematic I posted. The bottom of resistor R3 and the debug jumper should connect to pin 4 of the IC (RA3) not pin 2.

    Schematic Ok I will give this a try, here is the schematic. Well I cut off the bottom, That bit at the bottom labeled TP2 is the common return to the tester ground. The resistors at the left are the remote unit. For the OP's application these resistors would be seperated. Each resistor when...

    As I replied in post 17 I have a circuit that does what you want, it runs off 3 AA batteries and uses 8 parts. It can identify 10 cables. If you send me a private message with your email address I will send you all the details.

    I have been working on something like this to sort wires in a bundle. I havn't finished building it yet, it uses different resistors that connect to the remote wire ends. The readout device uses a PIC 16F676 that reads the resistor value through the ADC and shows the wire number on a 7 segment...

    How does this LED driver work?

    No, you wont need a resistor. As long as your led string is in the voltage range of the supply (25-40 volts) and the current requirement is less than 1500ma you can connect them directly.

    555's are terrible, no they're not, yes they are, no they're not

    http://www.customsiliconsolutions.com/downloads/Revised%20Standard%20products/CSS555_Spec.pdf Have any of you looked at these ? Im not endorsing them, I have never used one myself. Im sure the 555 has it's place in circuits, however I have been doing circuit design for 35 years and have...

    New to site and need of a little help on relay circuit boards

    There are relay boards available on EBAY, but as Fish stated you need to know the voltage and current draw of the motors you plan to use.
