Frankenbear Synthamajig

Have you ever wanted a teddy bear that looks like Frankenstein and makes sounds like "bleep bleep bloooop de de bleep.... EHHHHHHHHHH...... dadadadadadadododododod bleep bleep bloop"?

Look no farther, you have found it!

Now you can perform the nights away with your new USB-Powered teddy bear instrument. Yay!

Step 1 Go get stuff.

Go get stuff:

1 - Small white teddy bear (preferably with red bow)
1 - USB cable
1 - Bicycle safety flasher
1 - Small speaker
1 - PIC16F877 micro-processor
1 - 20MHZ ceramic resonator
1 - LM386 audio amplifier
1 - 40 pin socket
1 - 8 pin socket
1 - PCB (cut to size of teddy bear)
2 - 10K potentiometers (preferably with knob)
2 - red knobs (available at Home Depot)
2 - 0.1uF ceramic disk capacitors
1 - 0.022uF ceramic disk capacitor
1 - 330uF electrolytic capacitor
1 - 10uF electrolytic capacitor
1 - 0.1uF polyester film capacitor
2 - 220 ohm resistors
1 - 10K resistor
1 - 330 ohms resistor
1 - Spool red thread to match bear
1 - Role of electrical tape
1 - Red and black 22 AWG wire

Tools:

[Very Interesting]

That's awesome!

[Warlrosity]

Is that usb cable off a iMac keyboard??????Actully I know it is butstill,

[Nextor]

Amazing !!!

[Tvman]

AWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW <br/>How CUTE AND KICK ASS!!!!!!!!!<br/>sounds like a cool thing to give to a girl dude! i would make it....BUT...probably very expensive for the parts and probably to much time and patience =/ looks kick ass thou! aight sweet bro <br/><br/>BYE<br/>

[StevenWC]

This is very neat. I will go home and make it right away. And yeah it does sound like r2d2 from star wars.

[randofo]

My god! That's one deadly looking cat! If you do end up making it right away, let me know how it goes for you. Post a picture or something.

[cowscankill]

lol the sound in the mov is like r2d2 from starwars

Hey there, I would really love to build this for my Physics of Music project and presentation. I know a thing or two about electronics, however, I know absolutely nothing about PIC programmers or micro-processors - what are they, how do I use them, and where can I buy them affordably? If you could reply or email me at [e-mail] I would be eternally grateful and definitely credit your work in my presentation!

No wonder my life always felt so incomplete, It was this that was missing all along... Seriously though, awesome instructable. I have been into microcontrollers ever since I found out what they were, and PIC's are fun as hell because their so cheap that you don't have to worry about blowing them.

[Lindie]

Wonderful, and bleep de bloop.

[tomc3uk]

Ok, first a vibrating apple, now this. Pretty cool!

[highwayman7]

Yes, I believe there should be caps (12pfd or so?) between pins 13,14 and ground. Hard to get that oscillator running with the xtal grounded at both ends. :=)

[randofo]

Yup. Whoops. Good point. I drew it wrong. I'm using a 20 MHZ ceramic resonator. The middle pin is grounded.

[mhswitch]

Hizza! A real instructable ;D

[garydion]

Very nice project. I like the sounds that the PIC makes here. One note about the schematic. I'm not a PIC guy, but I do see something wonky with pins 13&14 being tied to ground. Looks like some capacitors are missing.
