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.”

Custom Center Car Light

at 12:59 am. Filed under DIY Hacks

 

Toyota Tarago shows us how he installed some LED center lights on his car. Took a bit of hacking to get them in there, a hot tip of a soldering iron was used to do some cutting through the plastic. I have often done the same but only for some small sections. I think I would have taken out the dremel for that job but it would have made a huge mess. The original strip had some defects so Toyota Tarago ends up making his own LED strip from some spare parts. The result looks great though.

Arduino Lithium Battery Charger Project

Arduino Lithium Battery Charger Project

 

Electro Labs has a new project posted, this time it’s an Arduino Lithium Battery Charger. With Lithium batteries you can’t just stick a trickle charge on the battery and call it done with a lot of older battery chemistries. There is quite a lot of technology packed into the design to get the job done and lots of room for user customization.

“The lithium battery charger circuit is designed as an Arduino Shield. So the main controller of the board is Arduino. But the battery charger IC on the board,LT1510, can also work alone. R3 and R4 sets the charge cut-off voltage, R2 ,R24 and C5 adjusts the charge current limit. With those passive component configurations, LT1510 can charge the battery and know when to stop. But we want to build a user programmable charger. So we had to take control of these functions.”

DIY Small Bench Power Supply

DIY Small Bench Power Supply

 

This project by is a nice DIY Small Bench Power Supply. I like the case design which is lettered with the toner transfer method. Great looking results.

“The heart of the unit is basically the same as on the other power supply. It is based on the LM2596S. This IC can handle up to 3A with a good heat sink. I would use it only for 2A to be on the safe side.”

Tiny Thermal Imaging Device

Tiny Thermal Imaging Device

 

Mike Harrison from Mike’s Electric Stuff shows off how he used a small thermal imaging sensor and incorporated it into a custom little project with a iPod Nano screen. With a tiny bit of polish this thing would be a great product on any hardware store shelf!

$100 DIY Car Computer

at 11:31 pm. Filed under Complex Hacks, Computer Hacks, Cool Gadgets, DIY Hacks

 

If you need some computing power on the go you might want to look into adding a car computer. Sentdex shows us how he does it on the cheap, the top of the great find is the $17 monitor. It has a Raspberry Pi as the heart, an ODB interface and a camera to loop record. An interesting power management system allows the system to detect when car power has been switched off and gracefully shut down the system.
