Title: Make your own BS2
Post by: 555 timer chip guy on April 20, 2007, 04:21:31 PM
I gust fond out that you can make you own BS2 for $15 I am trying to make the BS2SX here are the schematics for the BS2 and BS2SX.

i saw this too for some time ago, but you need the PIC16C57 from Parrallax.
they have flashed/burnt/programmed it in a special and secret way.

there is the kit, i dont remember if you could just by they chip, and make the rest yourself.
its only 30$, which is pretty cheap for a BS2!

May I ask what a BS2 is?   ???

bs2= Basic Stamp 2, it is a programmable stamp made by parallax.

Oh.  I should have figured that.  Hmmm, very intersting.

Thanks  ;D

you can just buy the chip and you save evan more money, I made the BS2sx (normally $60.00)
for under $15.00

Hmm do you mind going into a little detail about where you got your parts, and how you did it? Under $15 seems a really good deal, so I might want to try doing that too..

First off the schematic is in the first post, the three main parts you need are the interpreter chip the EEPROM and the resonator. you will also need some simple components such as resistors, transistors, and a regulator (refer to the schematic). the interpreter chip, the EEPROM, the resonator, and the regulator you can get for http://www.parallax.com/ look under OEM components (they also sell a kit but it's $30.00)  the rest you can get from any electronics company I got mine at www.jamco.com (they also mite sell the regulator and EEPROM).

but they dont have analog to digital converters!

The BASIC Stamp’s I/O pins are perfectly suited for digital input and output with TTL/CMOS level (0 to 5 volt)
signals. However, you can use some special commands and techniques to input and output limited analog signals.
For example, the RCTIME and PWM commands can be used to read a variable resistance or output a variable
voltage from 0 to 5 volts. The I/O pins can not be used to read analog voltages by themselves, however, but this
can be done by interfacing the I/O pins to an A to D converter chip.

you should look into using an Atmel AVR chip like the Atmega168, its a lot easier to work with and tons cheaper than the BS2

I would personally try and boycott parallax as much as possible. I hate the monopoly they got. I'm also thinking that about 5 books I have are from TAB probotics, who seem to be very parallax loving. Boo.

have you looked at Admi's $50 robot project?
that's what he's using.
with those tutorials and a book on C you should be all set.
