Give a child a toy and they're happy for an hour.
Teach a child how to make their own toys, and they're happy for life!

Don't just learn the Programming Board, learn a chip or module!
You can find all the programming code on the internet, but buy a RoboGuts™ Kit and get all sorts of reference code in one place!

Here you see how a chip/module connects to the RoboGuts™ circuit board so you can build projects in one day.

PICAXE 28X2 Module/RoboGuts
Following info was obtained from the PICAXE Product Details Page

A compact PICAXE-28X2 module which contains the popular PICAXE-28X2 (PIC18F25K22) chip, voltage regulator, download socket, and reset switch in a convenient 28-pin, 0.6" wide, format. Supplied as an assembled and ready to use module it is ideal for breadboarding work but will also find a suitable place in other projects.

This 28X2 module supports up to 22 inputs/outputs with 16 analogue/touch sensor channels with an operating speed up to 16MHz using an internal oscillator and 64MHz using an on-board resonator. This chip supports 4 internal and up to 32 external program slots and is capable of acting as an i2c slave device.

The 28X2 supports enhanced features such as configurable i/o pins, ring tone music and touch sensor inputs, i2c, spi and high-speed serial with background receive. Scratchpad memory plus separate Data EEPROM and Data Table are supported. See the specification tab for more X2 series information.

Body box, 2 Wheels, Top, Skid and Face ... the whole kit can be 3D printed on most printers in one day.


Only 1 rubber band on 1 wheel for traction is why the bot
falters a little in the normal programmed operation,
but it is easily seen how the program works in the demo video.

ScardyBot ... Turns to Run Away
increase the turn radius of X0 closer to 180° to run away

ScardyBot ... Turns to Run Away
increase the turn radius of X0 closer to 180° to run away


Flip the direction and now you have a Psuedo SumoBot that goes after whatever is close!

Finds something in range and tries to stick to it like a poopie on your shoe!

Project X02 = PIXYbot


Click on the Image to Reveal the Programming Code

The PIXYbot is a miniFloppyBot with a RoboGuts™ and a PIXY CMUcam5.
The bot sees a color, displays the color in its body 3-color LED and speaks about the color it sees.

. . . . . . . . . . The one caveat to this is you need to have good lighting and bright colors for this sensor to see and
. . . . . . . . . . recognize colors correctly. Color lights and bacck-lit objects do not work with the PIXY CMUcam5.

Sensors are;
1x PIXY CMUcam5
1x Parallax PING or HC-SR04, or SR-05 ... almost any of the popular UltraSonics on the market
3x SHARP GP2D12 IR Range Finders
2x Sharp GP2Y0D805Z0F IR Range Finders
5x QTR-LRC-1A Reflectance Sensors

Project X11 = Musical Floppy Disk Drive

So many copy cats using canned Arduino software and hardware to play music on an old Floppy Disk Drive. I decided to unveil the simplicity of this so PICAXE users an start making songs ... maybe expand on this project since a 28X2 could probably manage ten FDDs. I plan to add this to the list of "X-Projects" at the end of the FREE beginner lessons on my website ...

Project X12 = PICAXE + DS1804 + Radio Shack Theremin

Almost Musical!



Sirens are Not Quite Musical Radio Shack Theremin

The first several experiments dimming a LED to control the Radio Shack Theremin just didn't work as well as I thought, but I was able to get some usable sounds that were fun.
