BEAM Online - The Yahoo of BEAM!

The Bicore is one of the easiest BEAM circuits to free form and can be built in 10 to 60 minutes depending on your skill level. I would recommend you read the whole tutorial first, this will GREATLY lower the chance of you making a mistake.

Parts needed:
74xxx240 (74HCT240 if you are going to use a motor driver or the 74AC240 if you want to drive the motor directly)
3M ohm Resister (If your motor turns to far put a smaller resister, if it doesn't go far enough put a larger resister)
2 - .22uF bi-polar capacitors (I would recommend part # P4966-ND form DigiKey)
Short piece of wire
IC socket (optional)

Tools needed:
Soldering iron
Wire clippers

Note: There is an error in the tutorial. The notch should be on the opposite side shown. Make sure when you orient the socket or the IC make sure the notch is on the opposite side shown. If you've already built this circuit using a socket just place your IC in backwards (which would be the right way).

1. Here's a layout of all the parts needed for this tutorial. For the tutorial I used an IC socket but you can solder and bend the pins directly on the chip if you don't have a socket. Cut the leads off of the capacitors but leave about 1/8". Save the leads!
2. Make sure you have the notch facing the right way (opposite of shown) and bend the pins just like is shown here.
3. In this tutorial I will mark the places you need to solder in red. Solder the pins together as shown. Use a small piece of one of the capacitor leads that you cut off in step one to put between the pins on the right .
4. Cut and solder on two more pieces of leads as shown.
5. Take a piece of shielded wire and cut it to about 1 1/4 in length and strip both ends. Solder as shown.
6. Take the two capacitors and solder them on as shown. Cut off any remaining lead
7. Use the rest of your leads and soldered and cut them as shown.
8. Clip the leads on your resister and solder it on as shown.
9. You're done!!! Hook-ups - Hook one lead from your motor to (motor 1) and the other lead to (motor 2). Hook your battery to ( + ) and ( - ) respectivly.
