    Led display Digital Voltmeter question

    Hello RumbaKing   I made one to with the same problem and I think it is because at the time I made it  I didn't have the right resisters. I used 5% instead of 1%. Maybe next time I go on a buying frenzy I'll stock up on 1% resistors.                                                            ...

    PCB Etching Tank - Do it yourself

    hello Fowkc     Hey guy if you just want to see how it works you don't need all this stuff. To etch one board, first is the transfer of the image to the board, once you have that any tank that the board will fit into will do. Hot water from a kitchen sink and a plastic bowl will work. Ferric...

    IC upside down?

    Hello charcoaldabs2   Sounds like you did good with the heat gun. My first time I tried to recyle parts from printer boards I tried using a propaine torch. Not a good idea, by the time I got done there wasn't much to do but get a garbage bag out.     Now I use a soldering iron with a sucker...

    PCB Transfers

    Hello   If you don't have a laser printer, I think the easy way would be to print it out on a inkjet then have it copied with a laser copy machine using office gloss paper.. Inkjet ink is water base and will desolve in water.                                       have fun                    ...

Got it to work, I have mine set at 200 volts for now, when I tried to set it for 30 volts I couldn't get a consistent reading.Breadboards are noisy lot of bad connections, lot...

    relay

    Hello   It depends on the relay on how much voltage and curent you need I sometimes use electronic relays that can be triggerd by 3 volts, not sure how many Mamp's but the Pic supplies enough and the relay can handle 220V at 20amps. A driving transistor works and some will say opto's will do the...

    LED Timer

    Hello  edeca   That could be done with a 555 time and a 4017 counter and some kind of gate for em plus transistors and resistors, and caps. Or a Pic could be multiplexed on one port to handle the 10 led's but you would need to use transistors to handle the curent for the leds. If I were to...
