DIY Infrared range disappointing, TV left wanting more... Answered
I have constructed what I like to call a circuit...and maybe therein lies the problem. The folks over at IRdroid.com have been gracious enough to post the schematic to the hardware that they also sell in the store. I have followed this as close as I could, however I have gone astray in 3 areas.
PROBLEM The unit works, my television turns off/on but only if I am within 3ft from it. The IRdroid.com website states that their device works at over 10 meters (18+ miles right?...I'm kidding, just a little Imperial system humor).
3 known differences
1. R5 calls for 1k2, I don't have one...I used a 1k and a 330 in series.
2. C4 and C5 call for 10uF, I used 10uF for both. However, one of them is 16v and the other is 50v.
3. I don't have a 6v battery, so I have tried 5v, 9v, and 12v with the same results in each case.
Would any of these 3 mistakes cause my range to be 10x less than the site claims?
