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
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
If you are looking to have some fun with the network of your big vehicle this video would be fun for you. The CAN bus is probably the vehicle bus that you have heard about but there are many other bus standards that are used when digging into your semi truck.

Ever wonder how data recovery is done when an micro SD card fails? HDD Recovery Services shows us how he recovered the data. He uses 800 grit sand paper and wet sands the card till the card PCB pads are showing. He then micro solders wires from a memory reader directly to the SD card PCB. He is then able to pull the NAND flash data and save it
DIY has used OpenHab is used to build a home automation control system using a Raspberry Pi. They are controlling an RGB strip. They are using some Adafruit modules to interface the Raspberry Pi to the light strip. “openHAB is a software for integrating different home automation systems and technologies into one single solution that allows over-arching automation rules and that offers uniform user interfaces. This
Long range data transmission can be useful. There are lots of options out there but the cheap nRF24L01 modules with an external antenna can work wonders. iforce2d has done lots of testing with a nice DIY rig. He has a stationary transmitter and a receiver mounted on his car, the car rig has a GPS and SD card modules to that he has the ability to record the
