Ive had great results with the rs sucker. I like it because you dont waste any time inbetween heat
and suction. In an emergency i use caned air if all else fails.

Re: BasicStamp2
I never bought the kit, but i think pics and stamps are awesome. If your a newby, the stamp is
a great way to get started.

Re: LED Load Equalizer
I think your situation depends on the flasher circuit. As we all know, in the old days a simple flasher can was used on most cars witched basically shut off every 1/2 second due to heat generated by current. Depending on your flasher controller your bike might not need a load to flash!

Re: 120VAC control from basic stamp?
I think the max output of a basic stamp is about 30ma. Basically all you will need is a base resistor of about 1k feeding a 3904 npn transistor, and an ac relay that runs from 5 volts less than 150ma. If you find a solid state relay that draws less than 25ma you can connect it direct. Dont forget th...

Re: atx power supply for hobby electronics
If you want your 12 volts rock solid, find the adjustment pot and feed in 12 volts with a 50k pot.
1. remove original pot
2.connect 12 volts to a 50 k pot to the pot trace
that goes towards the 494 controller.
3. most will adjust the 12 volt rail from 8 volts to 14 volts at 10 amps all day long.

Re: Any Assembler (for PIC) wizards out there?
I just spent 4 hours troubleshooting an intermittent lockup on a pic 16f684 because i forgot about how the current memory bank must be restored in the interupt routine. Does any one know why the pics cant be designed with ONE BANK of memory and ONE BANK of program space? Is it a money thing? Id pay ...

Re: What's everyone working on?
Im working on using a pic 16f684 as a generic control circuit. I have a board with an lcd,pic and an op amp. Using the 2 atd's on the pic i can control the pwm signal out for voltage or current control. Working with double bytes is so hard i cant speak to humans anymore.<p>Last year i used a bs2 to ...

12 volts into 24 volts
Does any one have a schematic for a circuit that wouuld convert 12 volts dc into 24 volts dc.
I need 24 volts dc at 1.5 amps. The source voltage would be a car battery. I realise that this will require some type of switching ac circuit.
Thanx in advance

Re: 11.5Vdc / 12Vdc to 12.5Vdc/13Vdc
One way to add 1 to 2 volts would be to use a sub c 3000 nimh battery. This would be good for testing your theory on fuel proportional to voltage. We use these nimh batteries in rc cars and they perform well at constant current up to 20 amps. The only thing you have to watch for is running the batte...

Re: A HVAC THERMOSTAT USING A PIC
I recently had great luck using a commercial thermostat to power a large relay. I used the relay to power on and off my large AC(28000 btu).
i purchased the relay on line (30 amps 240 volts)
The relay has a 5 volt coil powered by a wall adapter, through the thermostat.

i am trying to decode dtmf signals using only a pic 16f684 and no other ic. Im able to decode what column the key was pressed in by counting th frequency.If anyone knows of some code (short)
to decode what row the key is in i would greatly appreciate the help
