Disguised and USB Re-chargeable TV-B-GONE

Post by ghpk »

This is my 4th TV-B-GONE, first two were on Arduino, Next two are ATTINY-85

Arduino one was posted here earlier, both Arduino ones are identical.

Attiny85 first Attempt, it was small, only big thing was the battery, a 500mah 4v sealed chargeable battery, but my lawyer friends
borrowed it in a party and I don't know when it would come back :-(
(as forum allows only 3 pics, I am posting complete album here-> http://postimg.org/gallery/1bsz24ne4/ )

Now comes the Best version I've built so far.

Its key Features are :-
[*]Very disguised
Easily Re-chargeable.
Can charge small phones too.
Long Range with wider IR Beam throw.
Easy to Carry

Hacked a Small so called 2600 mAh powerbank, which in-fact has one re-chargeable battery and makes use or voltage doubler kind circuit to
give 5v D.C. output to charge your phone battery.
for spaces issues I removed its big bold round battery and fitted all the stuff.
Used a old battery from a Toy RC Helicopter which is 3.6v and is rechargeable and is ultra light weight. (its old and inflated, will replace soon)

For IR Blaster part I am using 1x 2N2906 and 2x 2n3904 which drive 4 IR L.E.D.'s
The 2 white IR blasters are Wide Angle one, Don't know the specs but I removed them from Extra IR Blaster I bought for my CCTV.
other 2 are dark ones bought from local shop.

push to trigger switch is placed after making a hold in cover, but used a small screw to make it clickable, then covered up the hole using electrical
insulation tape.

As the circuit of Powerbank is used to charge the battery is retained, the circuit also gives output on USB port which can accept a Standard USB 2.0 USB cable
and can be used to charge a small phone. tried a 1200 mAh battery based phone and it was charging, but failed on 3000 mAh phone.
as the battery is old It might be able to charge bigger phone once I get a similar small sized battery.
