ATtiny13A PWM Controller + Cyclone from a Supermarket Jar

You can buy a cheap NE555 PWM module. It will spin a motor. It will dim a lamp. But it won't do soft start, soft stop, voltage compensation, protection, or hysteresis.

This one does.

Built around ATtiny13A, it works with:

• Brushed DC motors
• High-power LEDs and halogen lamps
• DC heating elements

Same hardware. Different loads.

The controller is paired with a cyclone dust collector — made from a supermarket jar and a mattress pump blower. It keeps the CNC clean without spending hundreds on a dedicated system.

Power limits depend only on MOSFET and diode. Scale it up — from a few watts to several hundred.

The whole process is documented: KiCad files, laser engraving, etching, soldering, and testing.
