PT2399 Spring Box

[@anthonyludington8320]

I just bought a few of these boards and I love what you chose to do, a sort of cinematic/sound design instrument. Inspiring! I like that you used the jack so it can be the unique instrument or an effect unit still. ✌️

[@edwardfletcher7790]

What a lovely cheap little spring reverb ! This is such a wonderful time to be in electronic music !

[@KRAFTWERK2K6]

DUDE thank you!! I was planning to put my hands on one of these modules and always wondered where to solder a feedback potentiometer to. Thanks for clearing this up :D it's an amazing build.

[@SISKworks]

Glad this video helps. I also have a few different versions currently for sale on my Etsy page. Same electronics as this one but with just different boxes and springs. But it sounds like you will probably build your own. www.etsy.com/shop/SISKworks

[@SISKworks]

So…I just realized that I made an error in this video. Specifically where I say to connect the feedback control. In the video I say “C15” but that is wrong. The feedback actually connects to “C15” Sorry for wrong info in the video.

[@SISKworks]

Check out this video for a correct explanation. Skip to 13:40 for PT2399 delay info. kzbin.info/www/bejne/hXWZp5dsjrt1b8ksi=kLgpOYQDns279OWV

[@hoodiedude4204]

thats sooooo cool! I was looking up Pt2399 videos because I recently bought 5 pcs (just the ICs) to build a synthesizer module.

[@mahlonkarpaiya252]

C15 for feed back, We all make mistakes some times. Great work and thanks

[@theTerribleFamiliar]

Man I want to build something like this. Feel like I would need a very straightforward guide to get there. Thanks for this video.

[@SISKworks]

theTerribleFamiliar What parts do you help with? I’m guessing more details on the on the delay board would help. Maybe a step by step process showing everything? I ask because I’m trying to improve my videos and I might use that same delay board on other upcoming projects/videos.

[@nene_blimboblambo]

@@SISKworks I think that is a wonderfull idea! Or maybe share some schematics/notes. I can only find schematics for when you get the parts on PCB/breadboard. I dunno, Im still browsing tools and parts so i can on fact vê a beginner

[@johnlowe3050]

Classy work.

[@bacterioelectronics8598]

Yes, exactly that ... Test-error. Very grateful now I will try to get something out of CV.

[@SISKworks]

Please make a video of what ever you make. I would love to see it.

[@baouftou]

very cool! would be nice to be able to run your signal before the springs as well. but really helpful as it is especially for ambience.

[@chinyyyere]

Thank u so much for this video! I really got inspired for my own project! Can u explain how u adjust the three knobs to the PT2399? I don't understand how exactly the knobs are connected with the rest.

[@dinaibrahim6911]

Hey! This is really inspiring, thanks for sharing! Could you explain more about PT2399? Where can I get my hands on one?

I’ve built a noise box recently and just ordered (hopefully) everything I’d need for this upgrade to it. A video on the wiring would be extremely helpful im trying to follow yours as a guide of sorts but I’m not adding the LFO from your other video and this one is FAST. Any advice on how to add this with an existing piezo w/ volume control circuit would be amazing

[@SISKworks]

I really do need to make a better video showing this wiring. A lot of people keep asking. But for now check out this video and scan to about 14 minutes in. I do a better job explaining the delay part. kzbin.info/www/bejne/hXWZp5dsjrt1b8k

[@pdsf521]

@@SISKworks I have and I’m so impressed with how you did that whole project I definitely subscribed if you ever put a video on it I’ll see lol I ordered 2 boards (1’s a backup or future project), pots and the resistors along with the 9v toggle switch. It’s my first attempt at a DIY “instrument” I think you’ve given me just enough to go by for it thanks

[@Nexotron]

Hi and thank you for your Video. I am too building a little Audio-device, combining two of these Boards for some Stereo-Delay. I Already knew about the points where you can connect Pots for controlling Mix and Delay-Length, but the Feedback-one was new to me. I instantly tried it out, but I can't achieve any effect when putting a 100k Pot between C17 and the center pin of the mix... I tried to slow down and magnify your Video, to get a clear look at you soldering points and see if I got something wrong... , but that didn't work... :/ I also don't really find any sources on this particular Module, only a bunch of info on the PT2399 Chip itself.

[@SISKworks]

Devox Mc Allister-Loxley van Hurten I’m so sorry but it looks like I was mistaken when I said C17 in the video. The correct spot is actually the capacitor near R21. Hope that helps.

[@Nexotron]

@@SISKworks Thanks for the quick answer! :) I also did some poking around and found the best position is before the Resistor R21, which is basically the same position as the capacitor you just mentioned. Very nice, the feedback gives the whole thing so much more depth. thanks again for your video and response! :)

[@SZINNAPALM]

Can this be done connected to an electric guitar and using the guitar strings as the spring part, what would I have to do differently to achieve this. Great box by the way. Thanks szin

[@nove991]

Hi, I don't understand how works the switch between input jack and piezzo mic, where the piezzo is plugged ?

[@jj74qformerlyjailbreak3]

I got more from this video, about the 2399, than any other video on Eww tuba Thanks Bunches. Maybe I’ll put a Veritable Spring on mine. With the Piezo on the headboard. “Hey Honey.... I hope your in the mood for Music today. “🤞 God Bless.

[@SISKworks]

FYI, I think I mad a mistake in this video. I might have said to connect the feedback mod to C17 but that is wrong. It should actually be C15 which is right next to that one.

[@jj74qformerlyjailbreak3]

@@SISKworks 👍 thanks. I actually got side-tracked with an exploding lipo in my notebook. But I would have eventually figured out. Thanks for your feedback, though. It added A Gain of 1 to my Heart. God Bless.

[@schoeffler_oliver679]

Hello, a really lovely Build you made :) I´m just building a similar one, more as a soundsculpture and i just buyed this board you use...is it possible to show the feedback connection (scematic), witch side of the Capaciator to the Mid- Pin of the Mix-Pot and witch size of the feedback- pot...? thx a lot

[@SISKworks]

I didn’t do a good job of showing that. Sorry. But check out this other video I did. Scan to about the 14 minute mark. I explained and show the connection points much better here. kzbin.info/www/bejne/hXWZp5dsjrt1b8k

Try a door stopper spring. It has a screw built in so you could just drill a pilot hole and add it on. It has a taper so it will give you another sound. Great work as always good job!

bha-ha-ha-ha! Very super music!!! ))))))))))))))) Like!

[@simoncardie9371]

I couldn't get the feedback mod to work. I did the C17 to left pin and centre pin to centre pin.Could it possibly be because I used an A50K pot instead of a 100? I love what you've done though. Very effective!

[@SISKworks]

Oops. Did I say C17 in this video? So sorry, it should actually but C15. Check out my other video, about 14 minutes in I start working on the delay. kzbin.info/www/bejne/hXWZp5dsjrt1b8k

[@bearshield7138]

very cool

[@bacterioelectronics8598]

Very good, do you have any scheme for feedback and time on that red plate? Would it be possible to pass the signal also through the springs? nice work !!!

[@SISKworks]

Bacterio Electronics Sorry, no schematic. But the red knob is a A100K pot and it connects between the center pin of mix knob and C17. The blue is delay length and it connects to the S and G points on the board but in order for this to work you must also remove R27. Hopefully this all makes sense. As far as sending a signal through the spring it is possible but just now with this device since there is nothing to make the spring move/vibrate with the input signal. Check out one of my previous videos called “HELL-O-phone.” In that video I have a spring inside an old phone that I can send a signal through.

[@bacterioelectronics8598]

Thank you very much help, it was simple yes. Although in the control of feedback did not seem to do anything in C17, as well as use this time just from R21 and there if I get feedback.

[@SISKworks]

@@bacterioelectronics8598 I was wrong when I said C17. The correct place for feed back is the capacitor near R21. Is that what you meant?

[@renaudgass3146]

Do you have a link for the pt2399 board??

[@SISKworks]

No but they can be easily found by searching for “pt2399 mic reverb board”

[@centralsound1723]

can you explain how the battery and on/off switch are connected and work?

[@SISKworks]

Sure. It’s really simple. The negative from battery is connected straight to the board. Then the positive from battery connects to the switch and then the switch connected to board. Switch is just breaking the connection between power and circuit.

[@centralsound1723]

@@SISKworks appreciate the help! and if i wanted to say add an LED light, how would i go about that? which points would i solder the positive/negative to?

[@outaspaceman]

Have you done any impedance matching on the piezo..?

No. Is that something that would help improve the sound? How would I do that?

@@SISKworks I use the circuit described in this: kzbin.info/www/bejne/l4CtpnaPnNKDhqc

does having a bigger piezo disk makes a difference in frequency response than a smaller disk?

[@SISKworks]

Alberto Versace Yes I think it does. I’ve tried small and large. Both work but the large disk sounds more full IMO.

@@SISKworks ok Thank you very Much =)

[@odinlazerdeath746]

any resources/equipment you can recommend for someone with no electronics background who's just getting into trying to circuit bend/build instruments?

[@SISKworks]

Sure. I would say first get a good soldering iron. I like Weller WES51 if you can afford it but there are other cheaper models that will also work fine. You will also need a basic multi meter, wire stripers, and solder. Then I would say buy a kit a cheap kit like the Velleman Voice Changer or a bit more like the Synthrotek PT2399 Delay and just get comfortable soldering and putting the kit together. Both of those kits are fairly easy and can be used in circuit bent devices. I've used both in other videos of mine BTW.
