wow, this is so retro, we used to make these boxes in the 80s, when i was about 10 years old, same chips, 555, 4000 series, 7400 series.. a bit more complex than just the 556 circuit though - more like your first box. We didn't really know what we were doing, just hacking together logic, multiplexers, shift registers, binary counters. We used to drive the neighbourhood nuts with battery operated ones, stuck to our bikes, roaming the streets, making crazy random "computer" noises..

such expressive facial expressions

Those books by Forrest are by far some of the best material I've come across especially when I started learning and even now! Super awesome to see them on this channel!!!

I built one, with a 8 ohm speaker. Then, connected in parallel to my 70W amplifier. THEN, I discovered the 8 ohm speaker could work as a microphone. My underwear became wet.

Generates some harsh square waves, so we'll use a round PCB... Lmao

I loved watching these videos when they came out when I was in college. And I really think they had a part in keeping me interested in electrical engineering. Now I've been working in the aerospace industry designing controllers! Thanks!

Thanks for the videos! Your enthusiasm is great, your are easy to understand, and the projects are interesting. I'm not electronics guy, but I get a lot out of these videos.

The circular PCB is amazing, Great project!

Awesome video, the facial expressions with the Punk going ... Classic. That's what a Terminator would look like if they could take a crap, and what it would probably sound like.

The circular board is a really nice touch. That’s a pretty build.

Thank you Colin, you made me smile, and wish to again do battle with electronics.

this a great build!!! thanks for making Collin !

Man...now that's the best trip I've seen in years. Jimi Hendrix and Woodstock...yeah. Go Collin.

Awesome! I am going to have to build one of these! Thanks, Colin!

This is my favourite video series on youtube. Even better than epic meal time.

i really like your style btw! very clear and instructive video, without much of bs other reviewer add!

collin's videos are the best!

I love your presentation style, it's really cool!

That sounds soooo good!

I don't understand, but I love watching Collin's videos. Very interesting.

I built and sold approximately fifty of these in 2003-2004, including one to Kaustic Machines. I believe I still have the shipping confirmation, in fact (they went to some interesting places all over the world and to some interesting people). I didn't call them "Atari Punk Synths", though. I've always found that moniker irritating, because these have not the slightest relationship with Atari hardware. I called them, "Ghetto Synths" and also "Sputnik One". To be real honest, to me, they sound pretty obnoxious compared to Atari's outstanding line of vintage audio ICs. This is strictly a starter project. You will hurt your ears and the ears of others. :D I'm sorry for all the pain I've brought others by having built these. haha The circuit, which I modified to be even more obnoxious, originally came from "Oscillators Simplified with 61 Projects", written in 1987 by Delton T. Horn. I still have that book!

This was awesome. Just love the reaction after the first sound, laughing out loud.

I made this circuit, it's awesome!

This is a proper make! I like it.

My favorite project is from 3 chips- The Coron DS7 . It's an easy build and a neat thing you can do is run the wires intended for the pots to a breadboard instead and then you can go from there to the pots. This way you have the stock build that works, but now you have a breadboard to create any mod you want. Quickly you will discover that you can make it a two oscillator synth without having to add any active components. I used the earphone jack on an AM radio to act as a modulated input:-)

Love this collin!

Awesome! I love your series:) Question, can you install a CV input to trigger it with an analog sequencer?

I love Collin!!!!!!! He makes it so interesting with his quirks! Haa..... Love the music Collin. Please don't change it.

I wish my projects were so neatly set out and soldered!

"The APC can generate some pretty intense square waves.... so how about a round PCB for geometric variety" Haha love it

I made one in breadboard but with two 555 timer ic. Really good for driving parents and siblings mad especially when they are watching tv! Now I plan to transfer into pcb.

Another great video. I really enjoy the earlier videos. The somewhat newer, more polished videos I like too but the older stuff is the sht.

Collin's videos are why I stay subbed :-)

i would love this man to teach me electronics at school

I've never much liked using potentiometers to control pitch. Since they're only capable of smooth transitions from one pitch to another, it's hard to make sounds with a complicated structure. This thing seems to do a pretty nice job of getting around that, though, so thumbs up to Collin! And the designers.

the Alton Brown of the electronics world, great videos

This guy deserves his own channel

love all dat pure sounds

nice video and very informative. Respect

I made one in an Altoids tin using two photoresistors. Definitely a fun project.

YEAHH!! More Collin please!!

I dont understand about half of what Collin is talking about, but he's still enjoyable to watch.

Collin: I only watch this channel for your stuff. More, please!

You do these projects for fun. It SOUNDS like you do not enjoy making stuff. When somebody makes something, it sure makes you feel good when you are done!!!!!!!!!!!!!!

This video is better than a lot of TV shows!

nice as always

mounted today, it works!

I just have to say: thanks for the video! and i really mean it!

yes! more Collin!

This guy is absolutely great! :D

Finally, something I can build!

What happened to this guy? He’s the best thing that ever happened to this channel.

This dude need to upload videos daily, with electronics tutorials for begginers would be helpful.

Terrific keep it up.

great job

Leonard Hofstadter + Matrix Agent = this genius!

@DanielLikesToast GND mainly means -ve battery connection but if both +ve and -ve conection are given than you can ignore it

Sweet vid. I'll be doing electronics next year at high school so I'll get into stuff like this. =D

yes collin! make more videos bro!!!!!!!!

COLLIN! PLEASE make a video showing the making of the 'soundlab'

LOVE THIS

Love the schematics on squared paper - So old school ;)

this is amazing :)

Collin's Lab; the only reason to subscribe to makemagazine...

My Atari Punk colsole is quite modded and much more expressive. I built two, put them in the same compartment, with dual controls and switches that turn the audio off between the two so you can make quick notes with it. My next Atari Punk Console experiement will be using a crap keyboard from a consignment shop to control the pitch (resistors of different values on each key. It will be monophonic, but it might be more controllable that way).

That is awesome! I always wanted to do some invention but I rather do this instead!

I love the background music

This is what makezine was about. Making stuff. And learning. The rest of stuff on make, well...

Hey Collin, where do you get your background music? I absolutely love it and would like to get the tracks. Thanks!

Can you please post a link to the first device you were using or show us how to make it. I know it might take long or be a long video but you if you can make a series or something out of it I would appreciate it. Or if you can give a slide show or text instructional, anything I would be very grateful. Thanks

Arrrghhh!!! Love this!

@guitarbass95 Isn't the Wedding band supposed to be on the left hand though?

How about a diy synth variable doorbell resistors on each bell button and one main siginal sync for whole house doorbell.

I have probably built 15 of these, but gotten 5 to work properly. Not too sure what is wrong, but suspect it might be the size of caps or pots

you're the coolest geek on youtube.

Collin's lab is awsome.....

Just a quick question, on the schematics for this there are wires labelled "GND", I'm guessing that means ground? and if so, what can that be connected too if it's running from a battery? Thanks to anyone that replies!

would it sound more pleasing if you filtered out square wave to be little more sine-like?

@Neversleeps1979 its the look of brilliance

Round pcbs are amazing

He looks like he is in heaven when he tries his creation! :)

awesome! Keep it up

long live nerds long live collin. ur a rockstar

Yesterday I build one from pieces. Oh yeah!

Brings back, well almost, memories of Playing Yar's Revenge on me 2600 years ago.

What should I do if I want to add more pots/switches to have more sounds?

Do you remember the guy from the video shop in Men in black ?!? Now he´s building genius circuits !! :)

@Acky0078 Any type of capacitor should work, as long as the values are the same.

hey collin i got an arduino uno for my birthday and ive already written a bit of code!!!!

yeah man. With regards to number 1 comment. you have the right voice for voice over, edits are good info is great. you should expand to all kinds of video's dude. Just go hard dude, GO HARD!!!!

Awesome, thanks!

You need a round PCB to keep the electrons inside with such a harsh waveform! You don't want them to go flying all over your shop.

freakin cool have to say. im loving dyi electronics even more ever video i watch :D

it's really cool

Still wish there was a parts list and maybe a better schematic, though I know I could probably find it online.

can u recommend me some more simple synth projects like this ?

yay this is seriously geeky stuff!

what parts do you need

First time I've seen this guy, I like him already. Where is the schematic for that first synthesizer he was playing with?

@minttuber That's the real problem with MakerShed etc- shipping doubles the price to UK, then you get stung for import duty and VAT. There's loads of stuff I want (e.g. useless machine, larson scanner, mintduino) but I'm not going to spend as much getting it as the gear costs!
