Wild and crazy hacks.
Gagan jain has built an interesting rig called the LIFI, it allows a simple transmission of audio using an LED for sending the audio signal and a solar cell to receive it. “The full form of LiFi is Light Fidelity. LiFi basically is a Wireless Communication Technology which uses Visible Light for Data transmission. LiFi is designed to use LED Light Bulbs similar to those present in our homes and
Ted Yapo is designing a crazy project idea, it is a Coin Cell Jump Starter! Just think next time you need to jump start your car you simply need to locate a coin cell and use this system to suck the power out in a usable way to start you car. Is it practical? Not really but it is cool is this theoretical idea would work. It is a
WeAreTheWatt is building a DIY LIPO Battery Spot Welding project. The construction is very nice. The PCB is very well laid out but of course even with a very heavy copper clad board it would not be able to handle the amount of current he needs. Heavy bus bars are used to pass the current through the fuse and across the switching transistors. There is a foot pedal activation method or
Instead of purchasing a new or reconditioned iPhone Scotty from Strange Parts decided to build his own. If he was in any other country this would have been near impossible but he was in China. There are lots of repair and recycling facilities that were able to sell him the bits and pieces that he needed. At 6:15 you can see Scotty purchase the display and digitizer from
This Edge Lit 481 Digital Voltmeter Display totally makes me want to build a clock with this mechanism. Can you imagine talking a measurement with this meter that oscillates, it would make a ton of noise. I can see this being great help if you were siting on a stable reading and waiting for something to avalanche. Via: Hackaday “These early NLS digital meters used a resistor dividing network and
Make it Extreme shows us how he built this DIY Plasma Cutter Notcher. The video shows the interesting build process. The end result is a great looking jig that handles the plasma cutter with precision.  End end result is a compact machine that can easily make very repeatable pipe notches and cuts.
Pop bottles normally find their way into the trash or recycling but if you have some time you can make some interesting rockets with them. The 2 stage water rocket above was launched to a height of 864 feet. This one quick to build the rocket portion, most of the bottle work is for looks and a bit of stable flight purpose. The neck of the bottle
