Battery saving TV-B-Gone with region/range selection switches

Step 6: Test

With one full charge (about one minute), I could turn one of my TVs on and off more than 40 times from about 6.5m (21 feet) away. Of course I used STOP button right after it turned on (or off) the TV. It does save power!

Hi Jeonlab,

I Have a question bout your circuit.
Where did the connections from LSP1 and LSP2 from the circuit are going to?

thx

Hi MrGentlemen,

As you can see in the circuit diagram, LSP1 is connected to the VCC pin of the ATtiny85v, which means it is to be connected to the power supply (batteries or supercaps) positive. The LSP2 is to the ground (battery minus).

Thanks.

Thx
This means , i need to connect the GND and VCC-connections wiht the LSP connections and connect all together to the power supply, right?

The LSP1 and the LSP2 pins are for those solder pads on the PCB. If you are planning to assemble on a board of your choice, you can simply connect your power source (e.g. batteries) to the VCCs and GNDs accordingly. In other words, all the VCCs and the battery plus are to be connected together and all the GNDs and the battery minus are to be connected together. Hope this answers for your question, but let me know if you need more clarification. Thanks.
