HOW TO DIY LO FI SAMPLER 

Damn! You helped me out a lot with your comment, i was exactly trying to do this! next project confirmed! thanks

@@Lonershy Hell yeah. And your video got me thinking about buying some of these isd boards finally.

@@Lonershy and please do a video on that as well, I would love to try this out too.But I am a total noob when it comes to electronics. This will be my first ever project. Also I just subscribed. I love your demeanor and chill vibe. Keep these diy videos coming. You are the first person who actually makes things easy to understand most DIY youtubers either show to little or make stuff really complex to understand. I watch a lot of them and you are really the first person who actually made me understand it in a simple and easy way. Your diagram made it super easy for me. Most of the times when I see a diagram I already loose my comprehension after 2 seconds. But your diagram made me understand it. So I'm really thankful you made this video. I hope you will make more of these. Thank you and have a nice day.

I didn't read it before and I also talked with another guy , and he gave me also another way, which is a diode and 10k resistor in series going to the play pin of the IC is all that is needed, CV voltage is max 5v ( adviced by @dirkk82 ) down my little knowveldge I'm wondering which one is the better one and the more stable :) hope this is helpful

@@Naked4FunTV So here's what's happening. The microcontroller is waiting for a signal to start playing the sample. That means, one way or another, one of the microcontroller's pins is either at positive voltage or "ground", waiting to receive a short pulse of the other polarity to say "go". That is, the pin has 0V on it, and is waiting for a few milliseconds of 5V (I'm assuming the circuit works on 5V and 0V, but it's not guaranteed), or the other way around. With the transistor method (google "transistor as a switch"), you're sending enough current to the base of the transistor to "open" the channel between collector and emitter. So if those two are on opposite sides of a button, you're just letting through whatever is waiting on either side of the button to normally be switched. This is a nice method for a lot of circuit bends because you aren't adding your own voltage to whatever you're switching, you're just sticking a door into whatever pathway is already engineered to be doing something. The diode/resistor method will most likely work just as good here, as long as: 1. The circuit in fact works on +5V (probably) 2. The pin responsible for triggering the sample is held at ground, waiting for a 5V signal (don't know, but not unlikely) The resistor is there to make sure that whatever you're using to send signals only sends a very small amount of current to the microcontroller, because it most likely can't deal with very much. The diode is general protection so that the microcontroller doesn't send any voltage back to your signaling device, since we don't know exactly what's going on with that specific connection in the circuit, there could be other things happening. It also drops your voltage signal a little bit, but that could be good or bad, since we're theoretically in the dark about what type of signals we actually need. I'd go with the transistor, because then I don't have to think about what's really happening in the circuit. If I went with the other method, I'd probably also add a voltage divider and move up from 0V to find the minimum voltage that triggered the sample reliably. And I'd want to be confident that it would only ever be triggered by a 5V pulse. This is far from a comprehensive explanation of what's going on, and an electrical engineer probably wouldn't be happy with some of it, but I hope it helps.

cool!

ye! go for it!

Yesh!!! That’s great!!!

Cool! Go for it!!

Nice!! Enjoy it!!

I want to know the same.

oh! thanks!

yes! i just learned a lot since i published this video :)

Just an FYI. This particular chip wouldn't work with the FT function that you posted at those two points. You need to connect the OTHER FT points together to get audio through.

@@CommodoreCrush What do you mean by "the OTHER FT points"? The ones second row first and second bar next to the white bar at an angle to it? The "other side of VCC and GND" so to say? Sorry if this sounds wierd, it's hard to be specific through YT-comments...

haha cool!

Nice idea! Im shit soldering too haha

midi would be a good idea just to get everything tight if you want an mpc style sequencing.

Check the PO-35 KO…

@@thelabby9998 Po-33

Glad u like it!

Yes do it!

Yes do it!

Thanks a lot!

Looks like you can change sample rate by replacing R2 as well. Have you tried that?

Wow, thank you!

Hi! Thanks! I buy the cases on a local electronics shop, but you can find them on amazon, look for "enclosure" for the pitch you need to replace a resistor (the R4 in the module) with a 100k potentiometer, thats it!

@@Lonershy Thanks for help. This will be my first DIY project :) I hope I don't burn down my house :D

yes, i made it, really easy, is like those microphones on cheap devices or toys. Thanks!

A little further playing around and I found if you bridge the 2 PE pins it will loop once it has finished recording. I guess you could wire a switch between the PE pins to turn this on and off.

YEs! it keeps it! maximum is around 20 sec if you record with the pitch level down, normal pitch is around 10-12 sec.

Thanks for watching!

thank you!!! of course I will make more :)

haha no idea! but i encourage you to try!!!

Maybe this could work ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZFuGabBUYBc.html

Hi! yeah, i saw that too but maybe people was complaining because of the quality of the sound without a volume potentiometer, it may ge very loud so it´s important tp put one. Go for it!!!

@@Lonershy I found something in my searching for the module that I thought was kool that u might like, it is a APR33a3 module (only available form India from what I can tell). It is similar to the ISD1820 but this one records 8 channels and in hifi(16 bit) . Thx again leading me to these awsome modules and projects.

to rectify the loudness, stick a resistor on the output of the speaker/line out. it is loud because the speaker pins are driving a speaker rather than line out level. info can be found here www.epanorama.net/circuits/speaker_to_line.html

pues dale ahí! jaja

I think you can use any cable... :)

i di it just connecting all outs to the same output

@@Lonershy ok thanks a lot !

All together to the same output!

@@Lonershy Thanks for the reply! I'm building this currently with five ISD boards, five Gate inputs, and two outputs via a buffered Y splitter daughterboard. The daughterboard also contains the 2N3904s necessary for the Gate input which was described in another comment here and it converts the 9V input down to 5V for all the ISD boards by an LM7805 voltage regulator.

Someone also mentioned the ISD boards requiring 3.3V, that is the suggested voltage from the datasheet however numerous sources indicate it will work with anywhere from 2.4V to 5.5V DC. 5V seems to work absolutely fine in my own experimentation.

Thanks for watching!

Did you fixed this?

@@fabiandeleon4636 I did not.

Thanks!

Having the same issue. Ever find a solution?

@madzpanda Nope. Damn thing is still off in a corner of the bench.

VCC

yooo thank you so much!!

Hahahaa

yes! super dirty mixed, for some reason if you share the batteries with more than one unit there is a big weird noise, if each unit has its own battery pack, there is no noise... i guess there must be a solution to that :?

@@Lonershy maybe some kind of grounding issue? I've read that they can handle the 5v from usb, so maybe powering them that way could help with powering multiple modules from one power source

@@hunterchapman9845 good to know! thanks!

Haha

Yes, there is, check the comments, someone was giving the steps to do it!

@@Lonershy thanks a lot, just read that about this, I also talked with another guy , and he gave me also another way, which is: a diode and 10k resistor in series going to the play pin of the IC is all that is needed, CV voltage is max 5v ( adviced by @dirkk82 )

Cool! Gonna try it!!

@@Lonershy do it in on a video please hahahah

yes, by playing with the pitch

you can use AA or AAA, 2 or 3. for loop mode, just put a switch connected to P-E

yeah, go for it! its profitable if you sell the time you need to put it together. regarding the sampling time, the time changes if you sample at certain speed/pitch if you go for a high pitch it will give less time...

@@Lonershy thank you so much, i will try

Hey! I am wrong in the diagram, you have to connect FT but the one in the back, so counting from top left, the first and third pins must be connected! sorry about that! anyway, my experience with feedback after messing with 10 of those chips is that works but half of the times once you record, the volume goes super low... but just try!

Lonershy yeah thank you so much man,I will try it~~~

:) thanks!

its explained on the video!

yes, is the one Im using :)

Yeah!!

Yes

@@Lonershy Awesome. Thanks for the tutorial. Def gonna try building some of these myself. Cheers!

Ok yes it happened to me, its probably something messing with the audio input or output, probably the output is fine because you can hear something, so i bet is the audio input, are you using the mic on it or have you connected a jack?

@@Lonershy I've taken the mic, and i tried different audio inputs. In the video looks like you are soldering 3 cables to the input, i´m only soldering 2 is that a problem?? Thanks for answering!!!

@@rucarucaruca it is only 2 cables. Hey, send me a video through instagram, im loner.shy on insta and lets find out!

@@Lonershy Thanks, I just did!

i guess so :)

Big jacks

Good!

Easy, board has it built in !

Barcelona!

Thank you!!

just asking, is the audio from the speaker loud or quiet? because he did say the quality is crappy so im a bit confused on whether i should make it.

@@erikacalysta loud. You can add a volume control to turn it down

@@funfactswithmaxx thank you!

​@@funfactswithmaxxYou ever figure out how to make the feed through work? I'm trying to make a pedal and without that I don't wanna pedal it. I've done what he said and doesn't work. Looked all over Google and it's fairly vague but seems like everyone says connect those pins together but I tried that 2 different ways and no luck. I know there is a way to but this has me truly stumped

yes!

@@Lonershy oh this is cool because I’m planning on building my own emu sp1200 diy because I don’t got 8k for a real one thanks for showing me this

@@gwbeats7454 damn! go for it! im building something that may inspire you a lot, I will upload a video next week!!!

:)

Hahahaha

Lonershy 🤟🏼😎🤟🏼
