Mini wii sensor bar mod for use at desk / computer monitor

I tried using my wii at my desk instead of using from a distance at tv and noticed the pointer/wiimote barely works without moving far away. After a bit of testing I figured out that moving the lights inside closer together allowed the wiimote to function properly, I taped the lights near the center of the bar for testing. If you don't want to cut up the shell you can just use it like this. I assume it wont work well on a tv after cutting but I haven't tested since I have another unmodified sensor bar

To make this cleaner looking the casing can be cut down and glued together. It was done mostly by eye so you can probably make it quite a bit nicer by making proper measurements.
First cut the top and bottom of the case into sections like is shown below

After cutting like this you can take the middle and outside pieces and get rid of the rest

After this you need to glue the sections back together I did this by cutting some small piece of leftover plastic and using superglue to put them over the joints, I then used tissue and superglue to fill the gaps. It's not pretty but it works

The next thing to do is cut a section off of the front piece of plastic to go between the led covers. use the middle piece of the three sections at the bottom of the image

To join this piece to the parts that cover the leds I added a small bit of super glue on the sides just to hold it together once it dried I poked some tissue into the gaps and then covered the tissue with superglue this creates quite a strong joint. Not sure if this is the best way to join them but it works

After its all dried it can be reassembled

Finished mini bar ontop of my monitor, it doesn't look too bad from the front

Oh jeez! Great timing!

I was wondering this too because I've been playing my Wii very close to my TV (also in my Computer/Drawing desktop) and noticed wonky movements. I was thinking about using the candles trick, but your solution fits my needs.
I'm thinking on using a Printer Rail to move closer or further the Infrared Leds.

having them on printer rail would be quite cool

How doe it behave at a normal playing distance?
not sure dont wanna set my wii up in another room my mums working there atm too

Just for the record, the Wii U Tablet also has the Wii LEDs at the top moved closer together so you can play Wii with it standing in cradle. They also only use one LED on either side above the screen for that.

What I don't know is what the effective playing distance for this setup is, but I guess it'd be between half a meter to a meter.

Neat. I wonder if moving them farther apart would make it work better at greater distances.
yes thats correct, the optimal playing range changes as the leds move apart, i used the calculator found at this instuctable https://www.instructables.com/Yet-Another-DIY-Wii-Sensor-bar/ to make a high powered 5v Ir bar so i can play on my 75" at about 17-20ft however that seems to be about the maximum distance that the wiimote can pickup the ir with sunlight/lights on, in a dark room with my valve lighhouses turned off it works at that distance but still not perfect, i think its the maximum sensitivity of the wiiremote.. I would love someone to hack the hardware for better ir pickup if that would be possible. (do ir receiver LEDs get more sensitive if you adjust the current/change resistance?

Stronger LEDs on the bar would probably be cheaper and easier than trying to increase the sensitivity on the wii mote.

I'm using the strongest leds i could get at 5v, and even when i reduce the resistance(increase current/brightness) past the listed maximums it won't pick up past 20 ft at all. Maybe I am lost here so I would happily experiment if someone can suggest something.

ok just started reading up at https://wiibrew.org/wiki/Wiimote#IR_Camera and so the wiimote only has a monocrome 128x96 pixel camera tracking the IR and it can only identify 4 points at anytime, so i'm thinking this may be more related to my setup, i've got big windows on both sides of my tv and a few behind me,

Yeah unless you get window panes that block IR getting some blackout curtains for the windows besides your TV will likely drastically improve it. You could try at night, or when it's cloudy outside, to see if it's really the sun before committing to anything.
