47 Projects to Do With a 555!
These are a whole bunch of things to make with the 555 timer IC with a note for each picture. I do not take credit for these schematics, they were made by Collin Mitchel. As you would probably think it took me a very long time to make this but it was night and i was wanting to waste some time so i hope you like it! I have descriptions for each and every picture so feel free to ask questions!

How to Collect Free Energy from Atmosphere - Homemade Circuit Projects
A free energy collector circuit helps to convert surrounding radio frequency waves to electric power and can provide 40 watts to 10 watts indefinitely. An option to increase the output power is achievable through proper set-up of an antenna. Placing an antenna in a close proximity of a large metal object helps generate additional power. Read More
5 Easy 1 Watt LED Driver Circuits - Homemade Circuit Projects
White LEDs are the lighting solutions of the future, simply because these devices can be lit brightly at relatively negligible power consumption. As an example, 1 watt LEDs are getting very popular nowadays due to their mini size and intense point brightness outputs, and as usual these require just a watt at 4 volts for generating dazzling illuminations.

How to Collect Free Energy from Atmosphere - Homemade Circuit Projects
FREE ENERGY ::: Look & build this. This circuit converts surrounding radio frequency waves to electric power. It can provide 40 Volts at 10 Watts indefinitely. The output power can be improved playing with the antenna. Placing the antenna near large metal objects gives more power. Antenna should be more than 150 feet long wire, placed horizontally as high as you can for best results. The pointing direction also is critical to the output. A highly polished aluminium sheet as a antenna improves..
