Weekly Progress
This week I make pcb and soldering power supply circuit, drive motor circuit. I make pcb with
dryflim>>irradiate>>acid and test circuit that my responsible. It has component is C 2200uF and 0.33uF before ic
regulate 7806 is located an appreciable distance from power supply filter and c 0.1uF after it for coupling and
constant voltage these devices are part of power supply. Drive motor circuit has TIP 41 and R 150 ohm which use
it because current enough drive motor.

Engineering Analysis
Strong Point
-Constant voltage - Current enough - Small circuit
Weak Point
-Transformer will be problem of area in circuit -ic regulate hot when connect load
- capacitor in circuit is tall
Next Week Job
-I will learn about step up step down circuit for don’t use transformer
