Hacked Gadgets Halloween Pumpkin Experiment

We crank up the juice on a 5mm LED to light up the Hacked Gadgets Halloween Pumpkin. LEDs have some incredible run time, quite often we don’t need them to run for thousands of hours. If you just need a fraction of the run time just crank up the power and get increased intensity. Watch the long version of the video below to see the math behind the hack. If you just want to see the cray results jump down to the short version. Don’t try to imitate the results since there is an electrocution and burn hazard with this hack. :)

Thanks to my daughter Alexis for carving the Halloween Pumpkin!

Thought it would be fun to jazz up some cookies for Halloween. After some playing around with the power, speed and focus the results are not too bad. You can see the full res images here.

In this DIY Electronic Fish Feeder an Arduino microcontroller is used to spin a drill bit which is placed to work as an auger to meter out fish food. If you want to build you own Brian goes through the build step by step.

Classic NES played using a Kinect

at 7:53 am. Filed under Game Hacks

 HWInterface

 

Tired of using a pesky remote control to play your video games? Paul DeCarlo used a Kinect sensor and some other bits and pieces to allow you to interface with some old video games!

Ingredients:

  • An NES console with game to test
  • An NES controller OR some wiring skills and a CD4021BE 8-bit shift register
  • 12 strands of wire, recommend Kynar
  • 8 1k resistors (technically any value from 1k to 50k should suffice)
  • 2 3.6k resistors (again higher not necessarily bad)
  • IoT board capable of running Firmata, Intel Galileo or Arudio Uno etc.
  • Kinect V2 Sensor for Windows OR recently announced Kinect V2 Adapter and existing Xbox One Kinect Sensor
  • Machine capable of running the Kinect V2 SDK

LG Flatron W2052TQ Monitor Teardown and Repair

at 1:43 am. Filed under Teardown

LG_FLATRON_W2052TQ_MONITOR_8570

 

After about 3 or so years my 3 20 inch LG Flatron W2052TQ monitors started failing. They were continuously powered on for their entire life and would simply go into sleep mode when the computers weren’t in use. You can see the repair video below that shows the 2 1000uF caps that were the culprit. At this time I have still to crack open the other 2 monitors but they were showing the same symptoms so I am sure the same 2 caps have also failed in them. When they were powered on they would come out of sleep mode with no issues and work fine, the issue was if they were ever unplugged and allowed to power down completely. The power on button would need to be pressed many time or the power cord would need to be plugged and unplugged many times over and over to get the panel to liven up. In the end they just didn’t turn on or they would just turn on for 10s of seconds before the panel just went black.

The teardown shows what I consider very poor build techniques. First of all the entire monitor is held together with plastic snap together construction. I would have loved to see some screws holding things together allowing it to be serviced easier. But what I was very surprised at was how the electronics cage was just floating inside the box. There is a bit of tape holding it in place and a few tabs on the base plate bracket. In the video at around the 25 minute mark you can see a poorly designed PCB mounting design. I could see this passing as OK if they were making a few hundred of these but I am thinking they make hundreds of thousands of these monitors.

You can see many pictures below, full res images can be found here.

LG I think your quality needs to be improved!

Kettle Cranked up to 10KW and Boils Water in 10 Seconds

at 2:06 pm. Filed under Crazy Hacks

 

Photonic Induction cranks up the juice on their kettle to 10KW, it lasted long enough to boil a cup of water in 10 seconds but it did self destruct during the speed round! Check out the 10 second toaster also. :)
