    Can you help me develop my invention?

    Hell, why not 2.8km! http://www.ebay.com.au/itm/2pcs-APP802-43-Wireless-transceiver-Module-for-arduino-/280846041048?pt=LH_DefaultDomain_0&hash=item4163ba7fd8 the point is.... you're just dangling bait to a lot of fish right now, and we're waiting to see if the bait is actually food or a...

But Why not tell us some...

    Can you help me develop my invention?

    no offense, but your idea however great is worthless if you can't explain exactly what it does, you can't patent an idea, come up with a circuit and some designs, sure, but you're being overly protective. there's so many ways of communicating with near by devices, bluetooth, wifi, or something...

    LED flickering with CC driver

    sounds like it's the vreg at fault.. easy enough to prove though, you have 2 choices... use a different regulator or.... use a low ohm resistor and mount it onto the regulator.. if it's cold hit a button which warms up the regulator for a few seconds, a 555 one shot then have the led's switch...

    LED flickering with CC driver

    I've had a dying diode, intermittently it would work and stop working, it behaved like a crack in a wire, depending on how you moved it it would occasionally work, but this diode was conducting on and off at random with no touching, it was weird i replaced it in the end all was good again.

    2.7v 200F Super Capacitors

    3000F !!!!!! Far out, puts my 400F cap to shame lol... I generally use a Switching Power Supply to charge these up, but I wanted to see what happens lol

    2.7v 200F Super Capacitors

    I would absolutely agree!

    2.7v 200F Super Capacitors

    Remember i'm simply drawing current to charge with, i'm not expending the cap's energy to "spot weld"

    eBay Arduino Uno Clones

    yes they work fine... but, watch out for voltage in on the DC barrel, i blew 2 up for using > 8dc volts

    9v dc to 9v ac conversion

    hence the picture... :)

    9v dc to 9v ac conversion

    Because the person said that when 9vdc was connected, the light came on and did nothing, I'm half wondering if that's because of the voltage drop? if you supplied say 10vdc (via the AC/DC rectifier) would the circuit come to life? if so, i'd bypass the DC rectifier.

    9v dc to 9v ac conversion

    you said you saw a DC rectifier... then the AC is being converted to DC. Bypass the DC rectifier and connect the DC supply up to where it has to go... - pictures of the circuit would give a better understanding.

    Which Microcontroller

    For simplicity sake, there's a heap of code and tutorials for use with Arduino or buy an Atmega chip and breadboard it... but as long as the PIC supports UART, you'll be fine.

    12V 2AH Battery Charger

    How did you originally buy the 12V 2ah charger? - try the same way but with a high amperage rating :)

    SN74HC14N hex inverter.

    I'm useless reading datasheets, hence the reason why i always buy a spare when ordering anything lol - so yes then :)

    SN74HC14N hex inverter.

    i mean is it simply 5v in 0v out? or 0v in 5v out?

    SN74HC14N hex inverter.

    http://pdf1.alldatasheet.com/datasheet-pdf/view/27890/TI/SN74HC14N.html I bought these by accident thinking they were a different IC completely.. So what's the deal with these? what's the basic principal ? Apply 5v and get a 0v out? - I can't find a circuit to demo this IC anywhere. -...
