DIY Plasma Cutter Notcher

at 6:09 am. Filed under Crazy Hacks

 

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.

UNI-T UT61E Backlight Touch Mod

at 2:57 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

 
CubeAMSPro100 has completed a UNI-T UT61E Backlight Touch Mod which adds some interesting features to the UNI-T meter. With a wave of a hand over the top of the meter he can now command the backlight to turn on or off. This isn’t a simple hack and it involved installing a custom PCB to handle the magic.

Add LED Backlight to a LCD Display

at 2:49 pm. Filed under DIY Hacks

 

Kerry Wong shows us how he makes some of his older gear a bit more usable by increasing the readability of the displays by Adding LED Backlight to the LCD Display. Turns out the LCD used some low intensity 5mm LEDs that were simply mounted in a way such that the light was directed through the rear of the display.

Arduino Controlled Industrial Stepper

at 11:36 pm. Filed under DIY Hacks, Electronic Hacks

 
AvE shows us that you don’t always need a complex expensive setup to drive industrial equipment. A simple Arduino setup is shown here to perform some simple stepper manipulation. The Arduino is connected directly to the Stepper driver which handles all of the complex microstepping etc. All the Arduino needs to do is enable it, chose a direction and pulse some steps at it. The result is a nice and simple repeatable system.

POP Bottle Rockets

at 9:46 pm. Filed under Cool Gadgets, Crazy Hacks


 

 

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 is simply friction fit to the multiple wraps of duct tape on the pipe that increased the diameter to provide a snug fit. The end of the tube has a cork stuffed in the end with a bottle cap and filler nozzle glued in place. This adds some safety since the cork can easily pop out if over pressured. An alternative would have been to glue an end cap to the pipe and drill a hole to mount the filler nozzle.
 

 

 
This Oobleck filled water rocket didn’t behave the way I expected. Oobleck is liquid and can be poured but when a hard force is applied it firms up. The Oobleck reacts to the high pressure and delays the launch until it is slowly forced out of the nozzle.

 

 

 
This alcohol powered rocket is great since it can be fired with the push of a button. A simple BBQ lighter is used as the spark source, a bit of rubbing alcohol fumes is used to power it but this design should be great with other things such as propane and hair spray.

Heavy Lift MOT Magnet

at 12:03 am. Filed under Cool Gadgets, Electronic Hacks

 
There are lots of uses for MOTs (microwave Oven Transformers).  The guys from Make it Extreme have come up with a great new use. Convert them to a Heavy Lift Magnet. They take a number of transformers, chop the top off the laminated core and weld them to a heavy base plate. They are then wired to a common power source and the surface of the transformer that will touch the metal being lifted is machined flat. The only limitation that I can see is that not all of the transformer sections might be touching the metal object being lifted. The lifting capacity for some free MOTs is quite impressive!

Thanks for the tip Curt

Gesture Controlled Lamp powered by Raspberry Pi

at 12:06 pm. Filed under Complex Hacks, Electronic Hacks

 

 

This Gesture Controlled Lamp is powered by Raspberry Pi. An infrared camera is connected to the Raspberry Pi allowing the system to monitor for wand movements since the wand has an IR LED build into it. OpenCV is used to decipher the wand movements. There are a few simple gestures that are recognized to magically control the light.

Via: Make

“After a recent trip to Universal’s Wizarding World of Harry Potter, my daughters and I decided to create a project that could use the interactive wands from the theme park, at home, to control our own props and gadgets. We called it Raspberry Potter because it was powered with a Raspberry Pi. We demonstrated the project last year at the Minneapolis/St. Paul Mini Maker Faire and this article — Ollivander’s Lamp — is the latest extension of that project.”
