Part list ---------------------- Tr1 BTA16-600 or similar (weaker or stronger - might need to adjust R3) LD1 Led TSOP TSOP1738, TSOP1736, SFH5110, no-name ones also worked fine for me (http://www.seeedstudio.com/depot/infrared-remote-control-receiver-module-wo-steel-shield-p-104.html?cPath=32_28) Sw1 Wall pushbutton instead of current on/off switch OPTI MOC3043 / MOC3042 (!but not MOC3041 - it might not work properly !) D1 6V2 ZD D2 1N4007 C1 *** 0,39uF / 275V C2 100nF C3 47uF / 10V C4 4,7uF / 10V C5 10nF R1 *** 47 / 1W R2 560-680 R3 220-470 (might need adjustment for particular triac used) R4 100 R5 1k R6 100 Jp1 Jumper (with jumper: Toggle mode, without jumper: ON/OFF mode) NOTES FOR 110V/50Hz system: (***) These values are for Europe 220V/50Hz. For 110V/60Hz these values should be: C1 >0,47uF and <0,68uF / >140V R1 47 / 1W and they were not tested yet for this device. For information, see Microchip Application Note AN954 (Capacitive transformerless power supply). Combination of R1 and C1 should be chosen so that available current is not less than 15mA. The device should work at 220V/60Hz system (Brazil) with values for 220V/50Hz. Mains frequency 50Hz/60Hz is not important for this project! NOTES ON OPTO-TRIAC USED: (**) If you decide to use both channels of this device, you really should choose MOC3043 opto-triacs since they require just 5mA to operate. If you are going to use just channel A, than MOC3042 will work just great. If you choose other opto-triacs such as MOC3041 the device might not work properly! I had problems with MOC3041 since it requires 15mA so there is no power left for the TSOP receiver and you can't turn the device OFF once you turn it ON. ---------------------- Muris Trax, 2010 www.elektronika.ba
