Programmable Servo Controller Project?

[nitrous2000]

Hi folks,

Has anyone created a DIY servo controller (1 or more servos) that can be controlled from a stand-alone crontroller board which records the servo signals for playback? The servos would be hobby grade and the amount of memory sufficient for 4 or 5 minutes of control.

Any ideas? Any DIY schematics/kits that might already be available? There is a ready built "Puppet I" controller for sale but it is already designed and sold commercially.

Thanks guys,

I doubt you will find there is a ready made PICAXE based kit but tentatively the project is certainly do-able.

You may receive more responses if you gave a more details (step by step) description of what you are trying to achieve.
You know exactly what you wish to do but your description is a bit broad.

You mention a "Puppet 1" controller. When mentioning such devices, it is good to give a link so others do not have to troll trhough the internet to find out what it is.
To help here is the link for the Puppet 1 and also Puppet 2 boards: http://www.bpesolutions.com/PuppetEquip.html#anchor39419

When you say "record servo signals for playback", what exactly do you mean?
Will something else drive the servo in the first instance and your kit must record the duration of each servo pulse on each channel and store this data for later playback?
What controls the servos in the first instance to get the signals you wish to record.

or

Can you just define the movements directly into the PICAXE chip in the program or in memory for readback and sending the data to the servo's at some time over and over.

How many (upper limit) of servos do you want to control. A PICAXE can (depending upon which chip you select) control directly form a couple to 8 servos.
Use the SD21 board for many more servos.
