styloBuzz sch2.bmp
The StyloBuzz is a small super lofi stylus synth that allows you to play one octave of notes, you can also modify the waveform in 5 different ways using the mode control.

It's really just an easy to build instrument that is lots of fun to play and can gives endless chip style sounds when you mess about with all the different modes.

You will need some basic tools, basic components, a circuit board, and the ability to program an 8pin PicAxe.

If you would like to buy a kit of parts including the PCB and programmed PicAxe you can find one here: Rarebeasts



Happy noise making.

Nice instrument!
Anybody know if is around one instructable or know how to do something similar with an arduino?
Thanks!

No circuit diagram or code. Is this nothing more than straight advertising for your own shop????
rarebeasts (author)  mpep2 years ago
Circuit diagram, board layout and code are all provided? Every thing you need to build this. If you are having trouble downloading then let me know and I'll reupload ASAP.
Cheers,
Brian
Can you save the circuit diagram as a jpeg or as an image because on Linux, to download EAGLE takes some extreme configuring.

Thanks.
rarebeasts (author)  blinkyblinky2 years ago
I've just upload a jpg of the circuit diagram for you. I had to zip it and upload as a file. It's at the bottom of step 1.
I hope that helps.
Thank you so much.

As pointed out by Randofo, I have now found the files I thought were not there. Good job on this project. :-)

I see the the circuit diagram as a download on step 1 and the code as a download on Step 4

Just get the board made, I've included every thing you need including the board layout.
Sorry to say this appears to be a mayor ripofff of a instructable of 2009, tic tac tunes: http://www.instructables.com/id/Tic-Tac-Tunes/

Are you nuts? Do you seriously think so, or are you trollin? One goes beep beep beep to the tune that's programmed into it - the other is a freestyle waveform generator. I can't believe you're making such a useless accusation. Do you find yourself having trouble keeping up with people in regular conversation? Do you often mean to eat an apple, but end up eating a banana by mistake?
Wow, no need to get your panties all tangled up, if you've learned to read at school you would have spotted the 'appears to be' part, to me, a person that has made neither, they look like the exact same thing, hence my reply.

But yea, sorry, forgot that the world revolves around you.
My balls are too big for you to tangle your panties around them. Sorry lover. Kiss kiss. ;P
Once again, learn to read, i clearly said your panties.

But i am just going to stop replying, since this is utterly useless, and i like instructables to much to get booted over some silly flame discussion. cya.
Exactly man. Exactly. You probably should have just said "Hey yeah, they look the same, but they don't sound the same! You're right!" in the first place. You know, had the balls to do that... without worrying that it means you can't fight, or don't have cred or some other BS. We all make snap judgements. We're all incorrect sometimes. It's nothing.
Just have to add a final remark since you appear to label yourself as some sort of winner;
I still say the instructable to me appears to be a mayor ripoff, your replys didnt really change that, hence my remark about dropping the discussion.
Besides if anybody is trolling it must be you, i made 1 reasonable reply, your the one to introduce drama, i just wanted to see a reply from the instructable poster, proving me wrong or not, simple.

But yea, reply whatever you want, ill just check back ina while to see if theres a reply from the actual poster.

I don't understand why you are calling this a ripoff, It's like saying that any Instructable that shows you how to bake a cake is a ripoff even if the flavor or look is totally different.
My Instructable has many similarities to the one you linked to, but the sound and look are verry different in my opinion, I respect your opinion and criticism is fine but, it just hurts to be called a ripoff when you put lots and lots of work into something.

Anyway, what's most important is that people keep making awesome Instructables and that we have this amazing community of makers.

I'm not going to bother. Clearly you don't have ears, and the ability to push play on both the videos supplied. Also clearly; you're a very small person (who thinks the internet is about winners and losers). Charlie Sheen supporter maybe? :P
Someone needs to obey his own pseudonym and keep quiet...Thomas. An accusation can be said to be unfounded but not useless by the way.

While I agree the two projects are different enough to warrant this one's inclusion here I can't help but think that I saw a similar project in Popular Electronics magazine somewhere around 1979.
Hmmm... so confusing, have opinion! But MUST STAY QUIET!!!!
There is much rejoicing.
Can I come to the party if I stay quiet?

you could do something very similer with a 555 timer chip, if you used the schematic in the link but replaced the buttons with the keyboard pcb and the prong

Well, adding a vid negated my images below, so I'll try again!

Thanks so much for the vid, pics and info! I kind of had an understanding of what a stylophone was but hadn't seen or listened to one before. Awesome.
nvnusman2 years ago
As Cephus suggests above, this appears to be an homage to and expansion of this simple portable "pocket Electronic Organ" from the UK, the Stylophone. The original is reputed to have been used by David Bowie and others in the Dark Ages of electronic music. rarebeast's circuit adds and enables customization but cuts of half an octive from the original. A new version is available from ThinkGeek.com for 20 bucks while apparently vintage originals can be had from Stylophone.com. I am reluctant to endanger mine by opening it up to show off its guts, but here are pix and a vid (because rarebeast made a musical instrument and didn't play a song?).

This takes me back I remember building a kit very similar to this when I was a kid back in the 80's It look almost exactly the same. It was one of those Dick Smith Electronics kits from Australia. Back when Dick Smiths stores actually sold electronics bits.
rarebeasts (author) 2 years ago
I've just added a pic of the circuit diagram so that you don't need eagle to see it.

Rolf Harris would be proud! Build your own Stylophone!

Once again, amazing work. Question, would this work with an 08m? It appears that you are using more variables and it would not fit...
rarebeasts (author)  blinkyblinky2 years ago
You're right, too many variables and it also runs at 32Mhz and the old o8m runs max 8Mhz.

The sounds in the video sound an awful lot like atari music. :)
