FPGA RGB LED Matrix Driver Project

at 10:22 pm. Filed under Complex Hacks, DIY Hacks, Electronic Hacks

 

If you are looking for an interesting FPGA project this FPGA RGB LED Matrix Driver Project looks interesting. There is a great overview of how the project was designed. Interfacing to the large display is quite complex but by doing it using a FPGA they have control over every aspect of what the hardware is doing. The current design uses the display as dumb output which gets what is to be displayed from a bluetooth connected computer.

“The various components of the overall system (PLL, UART, and Display Controller) are shown along with the simulation data. The outputs of the Spartan-6 FPGA board are then measured using a Keysight S-Series oscilloscope. The design of the RGB matrix is also demonstrated using a custom clock interface sent wirelessly to the unit via Bluetooth.”

Large Inverter Charger Troubleshoot and Repair

at 5:02 pm. Filed under Complex Hacks

 

 

Mr Carlson’s Lab had a defective Magnum Energy MS2012 Inverter Charger. When powered up the remote head unit indicates an Internal NTC fault. This fault indicates a temperature sensor fault issue. By looking through the diagnostic menu he could see that the system thought the FET temperature was at 151 degrees C when it was just powered on and should be reading room temperature. Carlson goes through the process of getting the unit working again.

Flaming Lightsaber

Allen Pan built this great looking Flaming Lightsaber. He got the inspiration from Tesla Down Under. By igniting some spraying methylated spirit the effect is a great looking flame.

Magnetic Stripe Spoofer – MagSpoof

at 12:49 am. Filed under Complex Hacks

 

We have seen this type of device before but Samy has done a great job making his tiny version. We have also seen some interesting alternative methods of reading the magnetic card information, the reading method is amazing that it can be read by the naked eye.

“MagSpoof emulates a magnetic stripe by quickly changing the polarization of an electromagnet, producing a magnetic field similar to that of a normal magnetic stripe as if it’s being swiped. What’s incredible is that the magstripe reader requires no form of wireless receiver, NFC, or RFID — MagSpoof works wirelessly, even with standard magstripe readers. The stronger the electromagnet, the further away you can use it (a few inches in its current iteration).”

Self-flying Drone Avoids Obstacles at 30 Miles per Hour

at 2:49 pm. Filed under Complex Hacks, Cool Gadgets

 
Check out this Self-flying Drone Avoids Obstacles at 30 Miles per Hour. It looks like this technology is
is not just for smart cars trying to avoid pedestrians and parked cars. CSAIL PhD student Andrew Barry has made this project open source for everyone to benefit from. It can fly through the treetops and dynamically avoid branches and tree trunks. It does this by using a stereo vision system.

“Running 20 times faster than existing software, Barry’s stereo-vision algorithm allows the drone to detect objects and build a full map of its surroundings in real-time. Operating at 120 frames per second, the software – which is open-source and available online – extracts depth information at a speed of 8.3 milliseconds per frame.

The drone, which weighs just over a pound and has a 34-inch wingspan, was made from off-the-shelf components costing about $1,700, including a camera on each wing and two processors no fancier than the ones you’d find on a cellphone.”

2.4GHz Waveguide Cantenna with Circular Polarization

at 5:38 pm. Filed under Complex Hacks

 

If you need to shoot your WIFI further than your regular WIFI can reach you can look into building this 2.4GHz Waveguide Cantenna with Circular Polarization to give you a boost in range.
“I decided to use a cloverleaf antenna as the driven element with a toilet brush holder as the waveguide. It must be noted that the waveguide in this version is not physically connected to the driven element as doing so will affect the VSWR. As I show in testing this is a powerful waveguide when used with a matched antenna with circular polarization and although powerful it is extremely directional with a beam width of 30 degrees.”

Omni Hoverboard

If you are looking for the latest in personal mobility have a look at the Omni Hoverboard. At first I was thinking this video was faked, but in fact this board is real and has recently won a Guinness World Record. Looks very tricky to fly around and as we can see the trials are being done over water for safety. I would have thought plunging into water would not be good for the motors, I wonder if after a plunge much of the parts need to be replaced?

Via: International Business Times

“The Omni Hoverboard features eight propellers and a frame made from carbon fibre. The motors controlling the propellers are powered by 12 lithium polymer batteries, which generate around 40 horsepower, but sadly, this currently generates a combined flying time of only 1.5 minutes.

Acceleration is achieved by squeezing a joystick made from a pair of pliers which makes the hoverboard go higher or lower, and speed up or slow down. The user is securely anchored to the hoverboard using snowboard binding straps, steering the board by physically turning in the air to change its direction.”
