Drone with 1000 Watts of LED Light

at 8:35 pm. Filed under Complex Hacks, DIY Hacks


1000 watts of light doesn’t sound like much. But 1000 watts of LED light mounted to the bottom of a drone flying overhead looks amazing. The video captured at the end of the video is stunning and the smoke scenes are mesmerizing.

DIY 1500 Watt Lab Power Supply

at 6:28 pm. Filed under DIY Hacks



A power supply is the heart of any good electronics lab. Hansaka Perera built his instead of purchasing one. It sure has a ton of bells and whistles. I don’t think I have seen a supply that shows what it is pulling from the wall, the LCD display in the center of his shows the total draw from the wall plug. The case of the supply is very nice and makes the supply look very professional. There are still a few bugs that need to be ironed out such as an LCD display that gets corrupted in some modes. There is also lots of customization that is to come. When looking inside the unit you can see that if anything the case could have been a bit larger to fit all of the electronics.

The case was ordered from China, it didn’t have any holes in the front but it kicked off his need for a CNC router which is a nice addition to his shop.

Raspberry Pi Vehicle Accident Alert System

at 9:56 pm. Filed under Cool Gadgets, DIY Hacks


SVS Embedded has built a nice proof of concept. It has a ton of peripherals hanging off the Raspberry PI. The system uses a vibration sensor and accelerometer to determine if an car accident has occurred. An LCD display reads out the information for the user. GPS captures the location of the incident and transmits it to a cell phone using a SMS transmission using the cellular radio.

PID Motor Speed Controller Example

at 10:24 pm. Filed under DIY Hacks, Educational, Electronic Hacks


SomethingUnreal has built a simple system to demonstrate how a PID Motor Speed Controller works. The system is spinning a piece of cardboard on a toy DC motor. The motor is powered by an H Bridge. An optical sensor provides feedback to the system so that it can see the actual speed and adjust the H Bridge accordingly. The software running on the PC is very nice as it allows for lots of variable playing and graphical output so you can see what the system is doing.

DIY EMP Generator

at 10:39 pm. Filed under Cool Gadgets, DIY Hacks


FPS Weapons has built this DIY EMP Generator. It uses some off the shelf components to generate some large EMP pulses with the push of a button. The device runs off a rechargeable lithium ion battery, a high voltage converter goes through a spark gap and then through a coil. The coil was made using some varnished wire. Hot glue was used liberally to keep everything in place. Use this device with caution since permanent electronic damage can occur with this type of device.

LED Snowflakes by Mike Harrison

at 10:26 pm. Filed under DIY Hacks, Electronic Hacks


Mike Harrison built this interesting LED mall display. For single install design it is quite involved, the system is very flexible allowing for it to be easily programmed and interfaced to. The use of RGB and a white LED is an interesting way to ensure you get a pure white light with no color mixing needed.

How to Build IOT Devices – Talk by Joe Menard

at 11:33 pm. Filed under DIY Hacks


Joe Menard had many needs for IOT devices in his life, he is an electrical engineer but needed fill in lots of programming knowledge to get his ideas to come to life. He started at a very low level even building a switch mode power supply, with 170 volts on board trace spacing was something that was very important. For the enclosures he didn’t simply buy something and stuff his circuit into it, he custom designed it and 3D printed it.
