stand-by

<< back


description:

Simple stand-by module based on attiny13 Atmel microcontroller. You can turn on/off any device (DIY subwoofer, amplifier or any other device) via switch or RC5 remote controller (more about RC5 >here<).
You can enter in programming mode by holding stand-by button for about 7 seconds.
For more, see the movie below. HF!

list of elements:

• TR1 - TS2/16 transformer (TS2/16 means, 230V AC / 6V AC - 0.22A)
• B1 - bridge (I used tiny, 1,5A circular bridge)
• C1 - 1000uF/16V
• C2 - 470uF/16V
• C3 - 4,7uF/16V
• C4, C5 - 100nF
• D1 - 1N400x diode
• F1, F2 - fuse handles (standard, vitreous, tubular fuse)
• T1 - BC546B
• IC1 - L7805
• IC2 - Atmel ATtiny13 microcontroller (+ DIL8 holder)
• PK1 - relay (I used HONGFA JQC-3FF relay, 5V DC / 230V AC - 10A)
• R1 - 100R
• R2, R3 - 4,7K
• R4, R5 - In my situation 300R (It depends from LED type, please do not take more than 20mA-mps for each LED from each pin of the microcontroller)
• R6 - 220R
• X1, X2, X3 - ARK2 connector, 5mm
• X4, X5 - ARK3 connector, 5mm
• TSOP1736 IR receiver (GND, +5V, DATA are marked on the 'elements localization')
