AIman,
The HB-25 only needs a single pulse to establish the motor speed. The PSC is designed to continue sending pulses to refresh servos. I don't see that there would be any advantage to using this setup.

Chris,
True...I withdraw my comment...it was predicated on the assumption that AIman didn't understand that the HB-25 only needs a single pulse to "set and forget" and was trying to use te PSC for the same purpose.
My bad...

Tom, · ·· Not a problem…Often the PSC is suggested to relieve the BASIC Stamp of having to refresh even 2 servos if the Stamp Module has a lot of other sensors to read and calculations.· In the case of sixteen HB-25 Modules, we’re talking about a different ballgame, but it’s no reason not to offer the comment in case the number of HB-25 controllers was a rhetorical question.· Take care.

Actually I am looking at running several motors and servos. The robot I am building will require (according to current plans) 15ish motors with about a dozen servos. Most, if not all motors will be running continously when in use.
This robot is built differently in the sense that the number of motors is extreme, however they are meant to work with each other both as back ups and as extra power when needed. By using idler pulleys with Servos controlling the slack this can be accomplished without a major problem.
Correction to that.
This is a centapid type critter modled after the one built in Asia using BS2's, only I want to - if possible and money is available - build one of about 150 segments. This is being built with the thought that additional modules will be added in the future. So each segment (ie set of 8 legs) will be one set of 16·motors.·Each section of each module uses two slots, one for each leg and the sections are hinged together using a simple cupboard hinge. It may be possible via gearing to use one motor per section and expand each segment to 16 indivual sections but that is a trial and error experament I think.
The thinking on this is that one stamp will control a set of RC controls powering HB25's and will be mounted upfront to make a "head" with the wires run back along the top of the body to each section as needed. As you may guess the segments will each have their own controller wired to the BS2 making this a lumpy looking critter.

·· There’s no reason it couldn’t be done.· Tom, one advantage would be a single I/O line to control all 16 HB-25s.· Take care.
