WS2812B LED Driver Project

WS2812B LED Driver Project

 

JEELABS did a nice WS2812B LED Driver Project that uses an ARM LPC810 running at 30 MHz to get things done.

“Sending 12 bits @ 2.4 MHz takes 5 microseconds. If we were to set the LPC810 to run at its maximum 30 MHz clock, we could probably drive the SPI hardware entirely via interrupts, but for a simple timed example this is not really necessary. Instead, we can let the SysTick timer interrupt the polling loop used to drive the SPI bus – without losing track of time.”

Numechron Digital Clock

 Numechron Digital Clock_1

 

built a very interesting clock called Numechron Digital Clock which is based around a very old clock. It uses an AC motor to keep time which keeps time based on the 60 Hz in the AC line.

“I really liked the Art Deco style of the Model 1364 case and chose to emulate it, although my clock is considerably larger than the prototype. While mimicking the original style, I employed considerable open space in the case design so that the clock’s internals would be visible. A Pennwood employee, F. Greenewalt, patented the mechanism for this type of clock in 1935. He developed an ingenious set of wheels, cams, and levers to flip the numerals and operate the clock. I consulted the original patent to design the mechanism for this clock.”

Power your House from an Old Washing Machine

at 3:55 am. Filed under DIY Hacks

 

Alternative energy is a hot topic. If you are looking to lessen your reliance on the grid you might want to look into a windmill or watermill. In this video Buddhanz shows us how a used Washing Machine can be turned into a power generator. Looks to be a cool weekend project. Most people would need to opt for the the windmill version but the water powered type is very interesting also.

Bluetooth Smart Car Project

 

Have a look at the Bluetooth Smart Car Project from Elecfreaks. If you are looking for a new project they provide some nice step by step instructions to get you going on this one.

Thanks for the tip Kathy

“DIY enthusiasts can build their own smart car with simple kits like building blocks, controlled with Bluetooth 4.0 joystick or app.  With simple communication protocol, the car can achieve human-computer interaction.”

Talking Autonomous Robot

DonEduardo built a Talking Autonomous Robot that has some personality. It wonders around looking around with his ultrasonic sensors, it can look to see if it is enclosed where it can take a nap. Every now and then he speaks. Very cute robot! The brains of the robot is Parallax based, the locomotion comes from a Roomba.

Color Tracking Hexapod

at 1:38 pm. Filed under Cool Gadgets, DIY Hacks, Electronic Hacks

 

Check out this Color Tracking Hexapod by in the Robot Shop Forum. The thing is a bit creepy! Not sure if there is a difference in programming but to me the first video looks like something trying to corner some prey and the second is more like a dog excited and ready to go running for a thrown ball. Nice job David.

“I am using the Pixy Cam to detect a pink object, in this case a pen cap, and move the body accordingly. All the PS2 controller functions work exactly as you’d expect; to enter tracking mode I press the triangle button. I am using a micro atmega 328 to connect and calculate the pan/tilt error of the object we are interested in. The height of the object is also obtained and used to determine how far away the object is.”

Shoulder Mounted Arduino Controlled Skull

Shoulder Mounted Arduino Controlled Skull

 

Steven from Rimstar.org built an interesting spooky Halloween skull to scare anyone who walks by. The video below goes through the construction details.

“Two heads on a body are scarier than one so for halloween I mounted an Arduino controlled skull on my shoulder with the electronics in a backpack and a hand controller hidden in my hand with the cable running down my sleeve. The jaw opens, the eyes light up and it makes a scary sound.

The biggest issue I ran into was getting a sound synthesis that could be done by the Arduino while still using a servo. Most sound libraries I found either conflicted with the servo library or required use of an abstraction layer.

Luckily the Arduino comes with a tone() function that uses simple PWM to make an 8-bit type sound that did the job while not conflicting the the servo library.”
