Order Parts for the EZ-Tuner
As a service to builders, I've ordered a bunch of blank EZ-Tuner printed circuits boards to sell. Also, I've been trying to buy up surplus stepper motors and optical encoders whenever I find them, and have a very limited number to resell. (If you know any good sources for these or other hard-to-find parts, please post the info on the EZ-Tuner bulletin board. Some sources are also listed on the downloadable parts list.)
Rules
  • Only one kit per customer (except for circuit boards, which you can buy thousands of, if you want.)
  • Orders must be submitted using my on-line ordering form. (I spent a week figuring out how to write the html code for the order form, so please use it!)
  • Builders outside the U.S. can order circuit boards only.
  • I have nothing to sell except what's shown on this page. When these parts are gone, they're gone!
I'm selling all my parts as "kits," rather than individually, because I want them to go to EZ-Tuner builders, and not to guys who just want to stock their junk boxes. There are four different kits, so before you decide what to order, please study this site and ---especially!---the FAQs page. Also...please don't order a kit unless you're serious about building the EZ-Tuner. I have very limited supplies available, and it's only fair that they go to people who really want to build the tuner. Please don't be a packrat!

1 $30 1 - microcontroller circuit board
2 -stepper motor circuit boards		 Contains the 3 (blank) circuit boards required to build the tuner described in QST. Builder will need to find a two-wire rotary solenoid to turn the inductor switch.
2 $40 1 - microcontroller circuit board
3-stepper motor circuit boards		 Includes contents of Kit1 plus a 3rd stepper motor board, for builders who want to use a stepper motor to turn the inductor switch.
3 $100 1 - microcontroller circuit board
2 - stepper motor driver boards
2 - dual-shaft stepper motors
2 - optical shaft encoders		 Includes contents of Kit 1 plus two dual-shaft stepper motors, like those in the QST article. Kit also contains two H.P optical rotary shaft encoders. Limited availability.
4 $130 1 - microcontroller circuit board
3 - stepper motor circuit boards
2 - dual-shaft stepper motors
1 - gear-reduced stepper motor
2 - optical shaft encoders		 Includes contents of Kit 2, plus two dual-shaft stepper motors, two optical shaft encoders, and a special gear-reduced (high-torque) stepper motor for turning the inductor switch. Limited availability.
