Did find that some of the spots repelled the solder dont know leave it for fresh eyes!!! Perhaps someone else can look at the schematic and let me know. D1 indicates whether or not the circuit is receiving power and will be the first indication that your circuit is built correctly, so this step is important. Originally designed by DIY electronics guru Forrest Mims III as the "Stepped Tone Generator," the Atari Punk Console is one of the most famous and recognizable Lo-Fi synth circuits ever. You can put either capacitor in either spot. Hi Julio, it would not be an easy thing to do unless you can make your keyboard put out voltages, the it would change pitch based off of control voltage.

I think the max voltage is 18V and the rest of the components will be fine with 12V. Connecting the 9V battery adapter jack is easy, so well do this first. Match up the black (negative) band on the diode with the white band on the PCB. Gutted .. spent all day putting it together and no sound led lights up going to look at it again tomorrow and check all the solder joints, then meter test it.

Currently you have JavaScript disabled. Well got a major problem with one spot that will not solder and because of that its not working correctly. Id like to add mounting holes to the pcb to mount in an enclosure. Good job! Hello! The red works fine and I can light it with my multimeter on diode setting, but the meter wont light the purple. If you dont hit any of those, you should be fine. Click here for instructions on how to enable JavaScript in your browser. Dual power supplies: use a 9V battery or save money on batteries with an AC Adapter rated at 5-12V 200mA Center Negative polarity. Anywhere from 0v-5v should be perfect! The wiring only really matters if you are using multiple speakers. The red wire is connected to the square through-hole next to the + silkscreen. With the LED legs bent under the board, theres a chance they are contacting something else and shorting the circuit out. So instead of soldering the the CV jack in the out spot on the board, I can wire in a piezo speaker, correct? Control Voltage (CV) input allows step sequencers and waveform generators to expand the sonic capabilities of the. I only bought the pcb so i wouldnt have any problems. -Zach, hi, is it possible to wire a keyboard(extracted from a toy, but with all the resistors) to te apc ??? Use any variable voltage source from 0-Supply Voltage for some glitchy goodness! Welcome to the NEW Atari Punk Console w. CV Input Assembly Instructions! Sounds like a fun project! If you wanted to power a bigger speaker, though you would need an external module to boost the signal. 3 potentiometer controls Pulse Width and Frequency contour the tone while the Volume control sets your output level just right. Click here for the Rack Based APC audio Jacks! Attention: Changes may occur after the Assembly Instructions are created and the photos may not reflect those changes. Maybe the red has a lower Vf?

The next part of our build are the capacitors. Glad it works! Please note: the 1/4" version does not have a 9v battery option. What can I say, Im a detail oriented guy. I havent bought one yet, but dont speakers have polarity? If you had to speakers with the same audio source but wired opposite of each other, the speakers will phase cancel and produce a less full and more hallow sound. If it doesnt work, go back through the instructions and carefully check all of your work. On the CV1 jack with nothing plugged in, the tip is being shorted as the TRS jack is normally closed. In order to post comments, please make sure JavaScript and Cookies are enabled, and reload the page. Required fields are marked *. Does not come with any other parts. thanks in advance. When you refer to C5 you actually mean C4 the first time, right?

When the CV input goes up in voltage, the frequency is supposed to go down, so that is normal. Store Page Ive un-soldered and tried to re-solder but it just wont take, im worried if i leave the tip on for too long it will come off the pcb and then im buggered any ideas? The package says it has a Vf of 3.3V and I can light it with a 9V battery and a 270ohm resistor so it does work. C1, C2, and C4 are non-polar ceramic capacitors, so their leads can go in either through-hole their silkscreen designates. Required fields are marked *. 3 potentiometer controls - Pulse Width and Frequency contour the tone while the Volume control sets your output just right. To solder this straight to the board, insert the longer positive lead into the circle through-hole and the shorter negative lead into the square through-hole. You should send me over some pictures of your APC. However, when you turn the knob labeled One clock-ways, the frequency should go up as well. How could i modify this and add a tiny 8 ohm Speaker in addition to the output jack already provided?? And does it matter which one goes where? New electrolytic capacitors will also have a longer positive lead. Module is available as a DIY project only.

Low part count = easy build for beginners! Just for kicks I wanted to swap in a purple one but it doesnt light. Wire the power switch as shown in the picture. Can I use these? 4 HP DC Jack allows for power switching so that battery power is only enabled when there is no AC Adapter plugged in. Your LED should light up, and you should have a gnarly sound coming out of your amp. C3 and C5 are 10F polarized electrolytic capacitors. Schematics Hi Buster, should be fine, this is not a 1V/octave oscillator, so if there is a pitch difference it should not affect much. if I want to run this off a 12v supply instead (a eurorack modular case) do I need to change any of the resistance / cap values? Low part count = easy build for beginners!

Your email address will not be published. -Zach. Store Page Click here for instructions on how to enable JavaScript in your browser. On the PCB, locate the through-holes for CV-IN and OUT Both of these have a T and an S next to the through-holes. 2 potentiometer controls Pulse Width and Frequency contour the tone. 2 and . The Schottky diode will be used for D2. Using the picture above, connect the mono jacks to the PCB. Dont forget to cut the nubs on the potentiometers as neccesary. Hmm, I guess the Purple needs more current! The frequency on my APC goes down as I turn the One knob up, also when CV value rises, frequency goes down. With more stepped tones and better bass response, the APC Handheld is a new take on a classic circuit! This is where the positive lead is inserted. Click here for instructions on how to enable JavaScript in your browser. thanks in advance for your attention. On the PCB, C3s silkscreen identifier has a square through-hole with a + next to it. Lets get started! Product Page DC Jack allows for power switching so that battery power is only enabled when there is no AC Adapter plugged in. Check it out HERE. If youre new to circuit-building, this is a great kit because its easy and makes some crazy sounds. Make sure the wire connecting to the longer lead goes into the circle through-hole (which is positive) and the shorter lead into the square (negative) through-hole. Bill of Materials Looks like youre using TRS jacks instead of TS jacks. * Your PCB may not look exactly like the photo, that is ok. What is important is that you short the same pins as shown in the photo. Speakers are a type of motor in that they will run in one direction when hooked up one way and run in the opposite direction when hooked up the other way. Powered either by Doepfer style 16-pin header connection +12V or Fractional power at +15V I have been reluctant to do this yet as I dont want to sever traces. Use any variable voltage source from 0-Supply Voltage for some glitchy goodness! There are 4 resistors to place onto the PCB. To wire the LED for a case, make hooksatthe end of the LED leads;solder the wires to the leads. They also have a longer positive lead. Congratulations, thats the end of the assembly! Your email address will not be published. Looking for those hard to find Audio Jacks used in this circuit? what i did was follow the path of where that through hole was supposed to go, make a small cut in the middle of the path [being careful not to have it exposed to any other part of the board (ground)] and then just soldered the lead of the component to that small cut. I wanted to do like that = Using a single 556 dual timer IC with minimal part count, the Atari Punk Console circuit is a solid, time-tested noise generator capable of outrageous square wave madness! Low part count = easy build for beginners! Control Voltage (CV) input allows step sequencers and waveform generators to expand the sonic capabilities of the Synthrotek Atari Punk Console from drone to arpeggio-like dynamism. 3 potentiometer controls - Pulse, Width, and Frequency contour the tone while the Volume control sets your output just right. If you received your kit and youre ready to build, the first step is to check to see if you have all of the parts. The APC needs three mono jacks for the CV-IN and OUT. They look similar, but they have different values that are printed on their body in small lettering.

Does it matter which wire goes to which hole on the PCB? Thanks for making us aware of the error. Comes with power cable and 2.5mm screws, www.synthrotek.com/store/eurorack-fractional-rack-atari-punk-console-p-219.html. 3 potentiometer controls - Pulse Width and Frequency contour the tone while the Volume control sets your output just right. The DC Jack is fairly straightforward: P = Pin, S = Sleeve, C = Switch. Would you have any suggestions or even a file that would depict any traces and vias, if applicable? Control Voltage (CV) input allows step sequencers and waveform generators to expand the sonic capabilities of the, Powered either by Doepfer style 16-pin header connection +12V or Fractional power at +15V. Be sure to include pictures of the top and bottom of the PCB and shots of the pots & jacks. If i press down on the joint it works fine. I would double check all the components around that potentiometer for anything that looks weird. Sorry about that, we usually try to send the same voltage levels with a kit. Bill of Materials Hey Ben, If you do not want to install the 9V DC jack and only install the 9V battery clip you will have to short the S and C pins for the 9V DC Jack like shown in the picture below*. The markings of 103 is 0.01uF and goes with C1. my knobs seem to work properly, raising the pitch as the knob is turned clockwise but my CV input seems to run the opposite direction of any keypresses so it gets some really funky bass tones if you push the octave way up and it makes for some really interesting harmonies but its all but unplayable except as a random noise source just kinda wondered if that was normal, Your email address will not be published.
