I'm putting together a group buy for a stepper motor driver, the
specifics are below. And to coordinate the effort I've created a Yahoo
group at http://groups.yahoo.com/group/DIY-StepperDriver/. This is a
members only group and membership is moderated, so when signing up put
"Stepper Driver" in the membership request.
I'm in the "find out how many people are seriously interested" phase
right now.
This stepper driver will drive up to 4 stepper motors, or 3 stepper
motors and 4 relays, and it's intended to be run off of a printer port.
Specifications:
Stepper motors:
Unipolar.
5,6 or 8 wire.
6-30V Per Phase.
1.5 amps max per phase.
Power input:
6 to 30VDC.
12A max. (Protected with fuse).
Features:
FET's Driven Output.
Internal 5V regulator for logic.
Optoisolator protected inputs.
PLD for logic (user modifiable, source code included).
PC board - double sided, silk screened, with solder masks.
Kit:
Complete with PC board, wire and external connectors.
2 extra FETs and optoisolators
SMD components mounted.
PLD programmed and tested.
JTAG port for Xilinx PLD.
Source code for PLD.
Hardware for optional heatsinks (user supplied).
Options:
1) Kit with SMD components mounted.
2) Kit + Case (includes blank panels).
3) Kit + Case + Machined panels.
Group Buy:
***** As of right now we are in the 2 units range *****
The more people that sign up and commit to the purchase of a unit or two
the cheaper it will be for all of us. The goal of the group buy is to
get the parts in large enough volumes to get a good price break.
10-49 Units:
Option 1 - no case or end panels - $131.39 + S&H
Option 2 - case + blank panels - $154.61 + S&H
Option 3 - case + machine and labeled panels - 208.39 + S&H
50-99 Units:
Option 1 - no case or end panels - $95.35 + S&H
Option 2 - case + blank panels - $118.57 + S&H
Option 3 - case + machine and labeled panels - 172.35 + S&H
100+ Units:
Option 1 - no case or end panels - $79.27 + S&H
Option 2 - case + blank panels - $100.60 + S&H
Option 3 - case + machine and labeled panels - 152.15 + S&H
Shipping and Handling will be a USPS Flat-Rate Box:
$10.95 Within the US ($8.95 + $2.00 for peanuts and anti static wrap)
$25.00 To Canada ($23.00 + $2.00 for peanuts and anti static wrap)
I would like to order everything on February 18th, 2008. Payment can be
made by money order, PayPal +2.9%. Details to follow.
See the files section for more information.
