Step 1: The Scheme Is Simple.
Step 2: We Need
- IRF840 transistor
- 2pcs 22k resistor
- 240k resistor
- variable resistor 100k
- 1-10 uf capacitor 25V
- LED 35cm white strip
- steel wire
- aluminum profile
- wire
Step 3: Connect Resistors and Solder on the Circuit Transistor.
Step 4: Glue the Transistor to the Radiator and Paste It Into the Body.
Step 5: Check the Work
Step 6: Set the Keyboard Aluminum Profile and Glue in a Convenient Spot Control.
Step 7: Connected to the System Power Supply Unit
Step 8: result
see before and after.
Detailed assembly and demonstration work can be seen on the video.
Thank you for attention!!!
