 This document tracks a number of small exercises to prototype. The goal is not a final product but skill building.
-* Control a stepper motor
+== Circuit Design ==
-* Rotary encode rotation data
+# Design a 555 circuit in KiCAD
-* Use a servo-motor
+# Layout on perf board & solder
-* Build a filter (Hi-pass, low-pass, mid-pass)
+# Layout on circuit board & etch
+== Motors ==
+# Manually drive a stepper motor
+# Wire up H Bridge to linear actuator (manual control)
+== Micro controllers ==
 * Use the [[AVR]] chip from an Arduino (off the board)
-* Build a class D amp
 * Use a PL2303HX chip with [[AVR]]
 * Use an SPI LCD with [[AVR]]
-Look into using shift registers for IO.
+After motor
+* Drive Stepper
-== Stepper ==
+* Drive DC with rotary encoder
-First, control it with manual switches.
+* Driver Servo motor
-I'd like to build a driver around the AtTiny2313 or an AtMega8. Use 4 pins for the driver out, and 1 pin out to indicate if the motor is stopped. One input pin for direction and one for start/stop. The rest will be used for speed and steps. The idea is that another controller can give the driver and order like "take 120 steps over 3 seconds".
-I should also do this at least once with a real stepper driver.
