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

MK2 VR Experience

at 10:01 pm. Filed under Cool Gadgets

 

Instead of going out climbing wall or the movies this virtual experience system can provide you a variety of experiences in one facility. The user uses VR for the immersive visual experience and physical objects for the tactile environment.

Cardboard Computer Build

at 10:28 pm. Filed under Complex Hacks, Computer Hacks, Cool Gadgets, What Were They Thinking

 

Mark Nesselhaus is building a computer the hard way, by using handfuls of transistors and cardboard.

 

“Attempt to build a computer using cardboard and brass paper fasteners as the base material for all of the logic circuits. Why? Well, the cardboard is free as my workplace puts it in the dumpster and I do not have the funds to buy better material. All of the electronic parts thus far were given to me by a friend who passed away and what better tribute than to build a computer. Except for the ALU all gates are either Nand or Nor using DTL. The transistors used are npn 2n2222 type or pnp 2n3906”

Interactive Alexa Raspberry Pi Christmas Tree

at 6:13 pm. Filed under Cool Gadgets

 
This Interactive Alexa Raspberry Pi Christmas Tree was built using an Amazon Alexa Dot, Raspberry Pi Zero, and a Neo Pixel LED strip.

“I’ve programmed my custom Alexa Skill to recognize three seasonal phrases and then send a message over MQTT to the Pi. These are defined in speechAssets – part of the Alexa Skill SDK.

Alexa tell Christmas Tree [to] change to red/green/blue
Alexa tell Christmas Tree to turn off
Alexa tell Christmas Tree to set brightness to 60 percent”

Cracking the Sega Saturn CD

at 9:34 pm. Filed under Cool Gadgets, Game Hacks

 

 

Debuglive takes a look how Dr Abrasive’s cracked the Sega Saturn CD system. The original copy protection of the system uses a physical wobble in the outer edge of the official game CDs. This makes copying the disks impossible since blank disks have this portion pressed into it when you get it. After a lot of reverse engineering and some custom hacking the system is now able to do lots of things that it was never intended to do.

Raspberry Pi Zero Ambient Lighting using Hyperion

at 10:29 pm. Filed under Complex Hacks, Cool Gadgets, Electronic Hacks

 

If you want to jazz up your tv with an Ambilight system now might be the time. We have seen other systems in the past that were impressive but not as good as this system. This new system is still a bit kludgy but seems to work very well and is nice and flexible to work with most systems. The Raspberry Pi Zero running Hyperion is the heart of the system and allows for lots of customization. The basics of this system takes in your TV HDMI signal into a splitter, one feed goes directly to your TV and the other goes into the an HDMI to AV converter. This AV signal is then fed into an AV to USB converter. The converter is plugged into a USB port of the Pi. This is not an ideal chain but since HDMI is a secure transport of video data there is no simple way for the Pi to read in the HDMI data. Now that the Hyperion software running on the Pi can see the live video signal that the TV is displaying it can calculate and output the appropriate codes that are fired down the serial LED string. Using the serial LED tape allows for a very simple LED layout.

Robotic EV Charger by PowerHydrant

at 10:52 pm. Filed under Cool Gadgets

 

In the near future when autonomous vehicles are buzzing around they will need to have some method of charging themselves. ARMdevices.net interviewed Kevin Leary from Power Hydrant who has a solution to this issue. With this system an electric vehicle will be able to have this system detect the vehicle type and have the robot charging arm connect power automatically. This is done by having the various types of electric vehicles modeled in the system and with the aid of a vision system the arm knows exactly what to do.

“PowerHydrant is an early stage startup focused on applying the “smart phone dividend” to deliver 3D sensor based conductive autonomous fast-charging for Autonomous Vehicles and eMobility. Based in Boston’s Innovation District, PowerHydrant is a member of the MIT Startup Exchange and part of Autodesk’s inaugural Startups in Residence (STIR) group.

PowerHydrant® has important advantages over other hands-free charging technologies:
1. Conductive robotic charging is unencumbered by power-transfer constraints and can charge at rates from less than 3kW to over 150kW (fast-charge) @ 99% efficiencies.
2. There are no vehicle-alignment, foreign-object, or EMC/EMI constraints.
3. A single charger can be autonomously time-shared (by 2 to 8 vehicles) for cost and congestion management. Optimal sharing ensured by Max-min fairness.
4. Simpler to Install or retrofit.
5. High efficiency means less heat, higher reliability, better safety, and better user acceptance.
6. V2X support assured.”
