Robotic Building Automation

at 12:29 pm. Filed under Complex Hacks

 

Robotic automation is great. Set and forget, once dialed in this system will create parts that are identical and not complain about coffee breaks. Love the creative jigs that enable the robot to handle materials that might not be placed with high precision.

Commodore SX-64 Repair

at 10:05 pm. Filed under Computer Hacks

 

Techmoan got his hands on a few SX-64 Computers. This is the portable version of the C-64 that everyone loves. He needed to do a bit of repair but in the end he got 2 working machines. They are still going for a good price since these units are still rare compared to the regular C-64 but you can find them for sale if you look hard enough. Teamed up with a C128 VIC disk drive emulator he now has access to the entire catalog of games on a simple to use device. I still remember the day when I had boxes of disks for the C-64 and being able to fit a few games on a single disk felt like such a win.

Intelligent Headlight Technology

Headlights today are much smarter than they were not that long ago. Using cameras the headlight system can detect oncoming vehicles and vehicles in front of you. The headlights can then block out the area that the beams shine, this means the end of constantly switching between high and low beams when you are close to other vehicles on the highway. It is also much safer since the headlights continue to illuminate as much output as possible without dazzling other drivers on the road.

DIY 1500 Watt Lab Power Supply

at 6:28 pm. Filed under DIY Hacks

 

 

A power supply is the heart of any good electronics lab. Hansaka Perera built his instead of purchasing one. It sure has a ton of bells and whistles. I don’t think I have seen a supply that shows what it is pulling from the wall, the LCD display in the center of his shows the total draw from the wall plug. The case of the supply is very nice and makes the supply look very professional. There are still a few bugs that need to be ironed out such as an LCD display that gets corrupted in some modes. There is also lots of customization that is to come. When looking inside the unit you can see that if anything the case could have been a bit larger to fit all of the electronics.

 
The case was ordered from China, it didn’t have any holes in the front but it kicked off his need for a CNC router which is a nice addition to his shop.

Raspberry Pi Vehicle Accident Alert System

at 9:56 pm. Filed under Cool Gadgets, DIY Hacks

 

SVS Embedded has built a nice proof of concept. It has a ton of peripherals hanging off the Raspberry PI. The system uses a vibration sensor and accelerometer to determine if an car accident has occurred. An LCD display reads out the information for the user. GPS captures the location of the incident and transmits it to a cell phone using a SMS transmission using the cellular radio.

PID Motor Speed Controller Example

at 10:24 pm. Filed under DIY Hacks, Educational, Electronic Hacks

 

SomethingUnreal has built a simple system to demonstrate how a PID Motor Speed Controller works. The system is spinning a piece of cardboard on a toy DC motor. The motor is powered by an H Bridge. An optical sensor provides feedback to the system so that it can see the actual speed and adjust the H Bridge accordingly. The software running on the PC is very nice as it allows for lots of variable playing and graphical output so you can see what the system is doing.

RGB Light Stick Painting

at 10:13 pm. Filed under Cool Gadgets

RGB Light Stick Painting doesn’t look very impressive when you watch it in action but with a long exposure and some well timed flashing lights the end result is amazing. The slow fading colors and a simple twirl of the stick looks very nice. The stick has 200 LEDs and is 2 meters tall. Not sure what is powering the unit but I suspect the LEDs are serial and have a microcontroller that reads in data from a SD card and displays the content line by line after being initiated by the push of a button.

Thanks for the tip Jim.
