Sensorbar - easy to build

[pit172]

Hi @all

I want to show you how i build a sensorbar, easy to do and cheap.
Hope the pictures speek for themself...
(I dont know the right words in english)




Here you can calculate the needed resistor and see how to connect the IR-LED's.
In my case the power-supply has got 4.8V (4 recharge battery) and i use 28 ohm (56/2) resistor.

It works great for more than 100 h without recharging.

I used this method to build a USB-powered "sensor bar" to use my real Wiimote with Dolphin, and it works great. All I needed was 4 IR LEDs, 2x 27 ohm 1/2 watt resistors, electrician's tape, a soldering iron and solder, and a USB extension cable with one end hacked off. (I should probably rebuild it to be more stable/flexible at some point. Right now it's just the LEDs in stick-on clips on top of my monitor, with the leads wrapped in electric tape.)

I also don't have to worry about the battery running out.

Looks good...
You see, i did it almost the same - with only 2 LED's wich works for me.
Second thing is that i only have to change the battery with an USB-cable, but i wouldn't crash my LCD-TV

I probably could have managed with a single LED on each side, but my Wiimote picks up several infrared dots around my computer that probably shouldn't be there (mostly from my speakers and various other meatl things in the area) so doubling up, thus making them brighter has helped avoid stray movements.
