APC 2.0 Kit
This is a redesign of the classic Atari Punk Console circuit. Originally known as the Stepped Frequency Sound Generator designed by Forrest M Mims III. The APC 2.0 features Top Mount assembly allowing for very economical manufacture and distribution. Components can be quickly placed with ease and even scrounged from discarded electronics.
Everything is included to make one device and house it in a case of your choice.

hey is there any bends/mods you can do to this
Yes, you can experiment with the CV input pins.
You can connect a guitar to this.
Starve the voltage to the circuit, get more uneven oscillations that way.
Add Blinking LEDs to drop the voltage and change the frequency.
Use a Sequencer to drive the circuit and making step.

culd u add this tone control ina an apc?
http://www.beavisaudio.com/techpages/BigMuffToneControl/
I’m building one of these with a vol. control because I don’t have a mixer and I’m making it super portable. For the pot, does lug 3 go to pin 10, wiper to output and lug to ground?
Try flipping the Output and the Pin 10 around on the potentiometer, one of the lugs must be connected to the ground. Report back with your findings.
how/where do you hook up the input for a guitar?
Astro take a look at this. http://www.getlofi.com/?p=2390 Its not finished yet, but the basic idea is there.
wuld a voltage sag work on these? just wonderinnn
It does work, the effect is more like a volume control however. A lot of Properboy videos demonstrate the effect.
do you just sell the pcbs yet on the website or will i be able to when the new store is finished only?
Hey Drew, you could order these from the new store. Its not finished as far as having all the products, but it works just fine. Thanks. http://www.getlofi.com/?page_id=2651
thanks, just placed my order….tried to make one on a blank breadboard an attempt 1 failed hopefully this will make it easier…then i can get a little brave after this one boosts my confidence.
is the parts list posted on the website somewhere since I only ordered the board…im still kinda new to this all and i cant figure out the caps u use in the delux kit.
The caps for the Bank are 0.1uF ( 104 ) and 0.022uF ( 203 )
The output cap is 10uF, one right next to the cap bank is 0.01uF ( 103 ) and the one to the right of the 556 is 0.01 uF ( 104 ) Hope that helps for now. The complete Instruction sheet is being redone and will be posted soon.
thanks “CM” it helps alot…hopefully it doesnt take me much longer to learn the basics but it just seems like theres so much to learn. going to the bookstore didnt help either most of the books everyone suggests are either out of print or kinda expensive.
Drew, everything you need to know is online. Make:Blog has great videos about electronic components. I would recommend getting the Kit next time, all the parts are included and it is much cheaper than sourcing 1-2 parts on your own. Most cases you will pay $10 just in shipping.
now it says the caps can be changed for different values to emit different tones..hence the cap bank but are all the caps interchangable for others or are some of them integral to the function of the circuit?
They are all interchangeable to a degree, some set better Frequency ranges than others. So if your caps are too big, you will not hear the APC, just slow clicks or if they are to small it will be way high pitched. The cap bank is therefore your best best at experimenting with values.
I can’t get the led to light up on the speaker and my kit didn’t come with wire
The LED will light up if connected across the speaker terminals. As long as the speaker is making sounds. Do not try to connect the LED to the Ground, it will burn out. Apologies about the wire, usually we usually very good about that.
I have sound coming out and the led to the speaker
still no light.
Does anyone know what the voltage
should be coming out the speaker terminals?
Shane It could be up to 9 volts, but because its PWM its not a problem. However it is possible that your LED got fried though. Got another one laying around?
