Uthe Sparkfun motor control board wires up:

Dir A- 12
Speed A – 3

DirB – 13

SpeedB – 11

Here is a wii Nii nunchuck based project

Here ist the demo software for the board:

 


this is the easy driver from spark fun

How do I come to terms with LANC?

One wire dual direction LAN.  Takes 4 identical commands for the rec. to see it as a valid command.

Goal: construct and program a robot.  the robot will be controlled via a Android Cell phone.

The final test will be a robot soccer tournament, with each student competing on teams for the championship.

the coaster Chassis will be the same as last year.

4WD_RobotBaseThe  Controller   is an Arduino .  The drive logic board will be hand made with relays as per this Instructible. EasyRelay

here is the actual relays we used

How do I configure a New Ubuntu Machine with all the usual suspects?

General Rules for aquiring hardware for linux MINT:

1. Don’t buy bleeding edge new stuff, but hardware that’s already on the market for some time. That increases the chance of the right drivers being present in the kernel of Mint 18. Additional advantage: it saves you a lot of money.

2. Make sure your graphics card is either Intel or Nvidia; avoid AMD and the others.

3. Wireless: Buy Atheros, Intel, Ralink or Realtek instead.don’t buy a Broadcom chipset.
