Free Steadycam

at 12:05 pm. Filed under Cool Gadgets


When you are shooting handheld video you will usually get lots of camera shake. The solution is closer than you think, Matthias Wandel demonstrates how some common things that you already have laying around can dramatically improve the video quality without spending thousands on something like a steady cam rig

Colour Injector – Arduino Mixing Colour Lamp

at 4:49 pm. Filed under Cool Gadgets



This is a great looking lamp that allows the users to interact with the lamp colour in an interesting way.

“Colour injector is an interactive multi-coloured lamp designed as a physical expression of the way red, green and blue light are used in digital interfaces to create a full spectrum of different hues. Syringes suspended below the lamp are connected to another set inside the body using clear tubes so that the ink can be seen moving towards or away from the lamp. The handles of the syringes inside the lamp are attached to sliding switches connected to an Arduino microprocessor that controls the colour output of rings of RGB LEDs. The system allows people to gradually change the colour of the lamp light in an unconventional way by providing a simple and intuitive interface.”

Car Instrument Cluster Clock using CAN Bus

at 11:35 pm. Filed under Cool Gadgets


Instrument clusters are no longer truly mechanical analog gauges connected to sensors directly in your car. The car is a big sensor network which communicates to the dash board instruments. This means that you can re-purpose them like Esko Haas has done with his 2003 Fiat Stilo closk. If you want to build on his work you can find his code here

“By the way, I’m using this board for connecting: http://www.ittgroup.ee/en/mikrokontrollerite-arendusplaadid/545-avr-tlcd-128can.html It’s compatible with Arduino Due and the CAN-bus shield from Seeed Studio, but is somewhat cheaper and much more compact than the combination of these. Got the tachometer and the temperature gauge working. The trick here is again to send all the parameters in a single message, not separately. Took a example from the first line here: http://www.fiatforum.com/stilo/174029-stilo-can-bus-question.html#post1874182
This also cleared some of the warning lights.”

POV Hard Disk Drive Clock

at 3:44 pm. Filed under Computer Hacks, Cool Gadgets, Electronic Hacks


Using an old hard drive, some 1 watt LEDs, a complete redesign of the hard drive motor drive circuit and an Arduino Marcin Gosiewski (damago1) has built a great looking clock. The display is nice and compact since he is using a 3.5 inch hard drive as his base.

“The project involves controlling HDD motor (3 wire brushless dc electric type BLDC) using open loop control without feedback, and using back electric motor force feedback to synchronize engine pulses with optimal point in time for them. Digits are displayed by flashing 1W power LED-s behind rotating disc with painted digits. Each flash is circa 150 microseconds. Due to POV (persistence of vision) effect the digits look very stable for the user. I am not using any special controller. Only Arduino, H-bridges for driving motor coils, and circuit for obtaining BEMF (back elecric motor force) from each coil and converting it to digital (high/low) signal to drive Arduino interrupt. I have designed my own custom board which is a modified Arduino (something between UNO and PRO NANO) + added additional parts including real time clock. It is designed to fit on the back of a standard 3,5″ HDD. Software is very dependent on interrupts. I am using not only officially available interrupts (attachInterrupt) but also additional libraries to use all available timers and interrupts.”

50,000V High Voltage Power Supply Build

at 1:40 pm. Filed under Cool Gadgets, Electronic Hacks

50,000V High Voltage Power Supply Build_2 


 built this interesting 50,000V High Voltage Power Supply which is fun but can be dangerous if not given the respect that high voltages demand. If you are interesting in getting some serious spark jumping action this build is for you. Best of all the main component can be found for free from an old TV.

“This high voltage power supply has been designed to output a fixed voltage of around 50kV, it could easily be converted to an adjustable supply by connecting a variac in case of using transformers or by adding some extra circuitry to regulate the power going in. I initially thought about a high frequency PWM to regulate the power going into the capacitors, but I abandoned the idea. I found that adjusting the frequency is enough to make the voltage vary by a significant amount, allowing some control over it, this happens because the flyback must operate at a certain frequency in order to maximize the output.”

DIY Camera Slider


If you want to amp up your picture taking options a camera slider could be a great option. Purchasing one can be expensive so why not build your own.  has built this one with a great list of required parts and a guide to make it.

Fun with ESP8266 and WS2812B LEDs

at 12:58 pm. Filed under Cool Gadgets, Crazy Hacks


CNLohr has been playing with the popular addressable WS2812B LED lights and the powerful (and cheap) ESP8266. In these videos he discusses how to optimize their usage together and provides full source code to get a foot hold on your own experiments.
