You can make them for MUUUUUUCH cheaper. My bosses dad at the hobby shop that I work for is a MIT grad and was a programmer at nasa he is helping me make the software and setup the optical trigger unit.
If you plan on making one I would advise on doing one that is an inertial dyno. The one in that pic looks like a break dyno. The break dyno puts an electonic load on the motor via the big eaddy current motor, they are heavy and very expensive. An inertial dyno uses a load like a round thick steel disk probably around 1-1.5" thick. Then It uses a flywheel and optical sensor like the fantom electric dyno. The sensor go's through a data conversion unit and then to the pc where the progarm decoads the data and computs in real time the hp rpm and torque through calculation that are preset into the program. The only real cost for me will be the drive unit, stand, decoader, optical sensor. If you are still interested in making one when I get the software finished I would let you use it. The other software alternitives are very expensive.
I didn't see the second link, the dyno in the first link is the one that I was refering too, the dyno in the second link is a inertial dyno and is very similar to what I am making.
