Do It Yourself T.V Remote Jammer (Infra red remote jammer)
Do you know how to jam TV Remote ?
Just point this small device at the TV and the remote gets jammed . The circuit is very simple . 555 timer is wired as an stable multi vibrator for a frequency of nearly 38 kHz. This is the frequency at which most of the modern TVs receive the IR beam . The transistor acts as a current source supplying roughly 25mA to the infra red LEDs. To increase the range of the circuit simply decrease the value of the 180 ohm resistor to not less than 100 ohm.
How to use ?
Point the infrared LEDs of jammer device to T.V sensor direction, press & hold CHANNEL + button in tv remote and slowly adjust the Potentimeter from min to max. The remote stops working at one point.
Leave the potentimeter.
Now whenever you point jammer to tv direction and press power button of jammer device your T.V remote will not work untill you power off jammer device.
NOTE : Both BC557 or SK100 transistors works.

DIY SOLID STATE TESLA COIL (SSTC) / (wireless power transmission to CFL bulb ).
( I Will upload video and pics soon)
What is a SSTC ?
What is a SSTC ?
A SSTC is an air-cored transformer that steps up a very low DC voltage to a very high AC voltage. This creates an electromagnetic field around the coil that is capable of lighting up fluorescent and neon light bulbs without any wires connected. It is fairly similar to a Tesla Coil.

In this post, I will show you how to build a small SSTC and will also give an explanation as to how it works.

Step 1: Parts List
For this project you may need to do a little shopping. The total cost for the project can easily be kept under 1000 rs.
Items Needed:
- At least a 8 inch long tube that's 1.5 in diameter, it must be hollow and non-conductive! I used a
piece of PVC pipe. - 25 rs
- A platform to mount everything onto (wooden or plastic ).
- Approximately 1 mtr of 14 AWG wire. - ~30 rs
- 250 grams of 35 AWG magnet wire . -140 rs
- Some sort of round sphere or coke tin to use as a top load (connect to upper end of secondary coil)
- One 50,000 (50k or 47K also works) ohm resistor. - 10 rs
- Two UF4007 diodes ( IN4007 will not work). - 10 rs
- One TIP31C transistor. - 20 rs
- Transistor heat sink & heat sink compound paste. ( use big heat sink to keep transistor safe)
