Wireless controlled lightdimmer
The meaning from this design is to build it in -i.e. a shaded lamp- and to switch this lamp on and off the normal way, just like it was switched before the dimmer was build in, then you could by exception dimming the lamp more or less with your TV remote control.
When you switch the power on there will follow a soft-start till the lamp burns at the previously adjusted dim level.
With the '0' button in TV mode you can dim the lamp, turn more and less bright.
The remote control should send more then one RC5-signal per button-press seeing that the first one is ignored, this does imply that when the remote button is pressed a short time, there nothing happens.
With the P+ and P- button from a system at choice you can adjust the maximum and minimum dim-levels and with the '1' button the start-up brightness.

Build your own LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and "Zero Out" function to make sure the readings are as accurate as possible ... [more] |
