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.”

Super Secure 4 Factor Lock Box Project

at 10:08 pm. Filed under Cool Gadgets, Electronic Hacks

 

 

 

Adarsh Jayakumar, Timon Amirani and Cameron Boroumand developed a Super Secure 4 Factor Lock Box Project for their Cornell University ECE 4760 final project. It uses a typed code, 3 pots set to a specific value, a knock sensor and a finger printer sensor. All they need now is a iris scan! Of course this box is built out of something that can be smashed into with ease and the electronics take up almost all the space in the box but just imagine this built into your steel and concrete reinforced safe room in your home.

Micro SD Card Data Recovery

at 9:34 pm. Filed under Electronic Hacks

 

Ever wonder how data recovery is done when an micro SD card fails? HDD Recovery Services shows us how he recovered the data. He uses 800 grit sand paper and wet sands the card till the card PCB pads are showing. He then micro solders wires from a memory reader directly to the SD card PCB. He is then able to pull the NAND flash data and save it locally. Not sure what he charges but based on the work that goes into getting it done it won’t be cheap.

Vehicle Electrical Troubleshooting

at 7:47 pm. Filed under Cool Gadgets

 

I am not a car repair guy but I have been enjoying the South Main Auto Repair channel. He uses lots of high tech and low tech to get the job done. The Snap On automotive testing system he is using is the tool for the job! It has tons of data in it for troubleshooting and it is also a digital scope (you can see it in use at 15:20).

 


OpenHAB Raspberry Pi Home Automation Build

at 12:39 am. Filed under Cool Gadgets, DIY Hacks

 
 

DIY has used OpenHab is used to build a home automation control system using a Raspberry Pi. They are controlling an RGB strip. They are using some Adafruit modules to interface the Raspberry Pi to the light strip.

 
 

“openHAB is a software for integrating different home automation systems and technologies into one single solution that allows over-arching automation rules and that offers uniform user interfaces.

This means openHAB
is designed to be absolutely vendor-neutral as well as hardware/protocol-agnostic
can run on any device that is capable of running a JVM (Linux, Mac, Windows)
lets you integrate an abundance of different home automation technologies into one
has a powerful rule engine to fulfill all your automation needs
comes with different web-based UIs as well as native UIs for iOS and Android
is fully open source
is maintained by a passionate and growing community
is easily extensible to integrate with new systems and devices
provides APIs for being integrated in other systems”

Wood Turned Bowl with Inlaid Letters

at 10:58 pm. Filed under DIY Hacks

 
Kevin Hou built a Wood Turned Bowl with Inlaid Letters as one of his final high school projects.  He used sketchup for design the bowl and common power tools to bring it to life. His school has a very well equipped shop, most of the build was created with conventional woodworking tools except for the letters which was cut out on a CNC machine. The build took 60 hours and was all filmed using an iPhone 6S.
