 Adjustment DC power supply 1.25-15V Max current 0.5 amp

Friday, July 18th, 2014

This is power supply that have Voltage output fine the value has 1.25-15V. From by Output current that be valuable about 0.5 amp that 12V and 0.2 amp that 15V. When Volt , from 220V houses reach transformer. It will modify Volt 220V to be 18VAC already to change rectifier circuit. Which D1, D2, C1 […]


 2 Lamp flasher using Mosfet

Friday, July 18th, 2014

we made a Simple flashing light by transistor BC548. It is easy circuit for LED display, but when need to use high watts bulbs or lamps will be extremely tricky. As this circuit We must add both transistors to increase current to load. Today I recommend a 2 lamp flasher using mosfet, we use IRF540 […]
