iPhone Headphone Jack Hacked back into an iPhone 7

  Scotty from Strange Parts known for building his own iPhone has been busy with another iPhone project. As most people know the Apple iPhone got rid of the headphone jack and even though many people hate that decision it looks like Apple will not be bringing it back. After 4 months of designing and Scotty was finally able to replicate the functionality of the normal headphone jack functionality. Of course this

PID Controller Theory

    Dave 2 over at the EEVBlog explains how PID works. Wikipedia also has some great info.     “A proportional–integral–derivative controller (PID controller or three term controller) is a control loop feedback mechanism widely used in industrial control systems and a variety of other applications requiring continuously modulated control. A PID controller continuously calculates an error value {\displaystyle e(t)} e(t) as the difference between a desired setpoint and

DIY LIPO Battery Spot Welding

  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

Laptop Hacked into a Cool Desktop PC

    DIY Perks hacked an old damaged laptop into a great looking desktop PC. The PC used has a damaged screen and was purchased for just $15. The guts were removed from the plastic laptop case but when exposed the tiny existing processor fan and heatsink was very loud. Replacing the fan and heatsink with a larger unit the system is now silent. The end result is a great looking

Safe Cracking Robot

    We have seen safe cracking robots before but they never get old. The guys at Spark Fun made a great one. It would be funny to  see a CCTV video of a vault heist that uses some technology like this. The safe cracker could setup his rig and read a magazine while the technology did the hard work. Via: Adafruit   “Nathan Seidle’s wife gave him this already

Infrared Transmitter Arduino Home Automation

  Upgrdman shows us how to make an Infrared Transmitter Arduino Home Automation system. This system uses a very high power wide range IR LED so that it would be great to be placed in the general area of the equipment you would like to control. If you are interested in making your own the example code is provided. “In this video I show an easy and low-cost way to
