Knowing the current weather condition is nice. Instead of turning on the TV and turning to the weather channel why not spend a few weekends and build your very own DIY Weather Station Project. It is based on the PIC 18F452 microcontroller and has great documentation. “Weather station with pressure reading, relative humidity, indoor & remote outdoor temperature display.Both Celsius or Fahrenheit & mbar/hPa or mm Hg supported. With calendar
I love complex machines that take lots of complex technology to perform a simple task. This Nickel-O-Matic Robot waits for a coin and then uses tons of servos and stepper motors to print a cool message on a wooden token. "The system was built as a number of modules to make design and trouble shooting simpler. The most complex of the modules is the inkjet system. At the center
Having the capability of data logging is a great trouble shooting resource. Often a meter with min/max capability is connected to circuits that are suspected to act up from time to time to prove that something strange is happening. However even when you know there is an intermittent issue wouldn’t it be nice to know what exactly happened and when. With this Analog Data Logger Project you would not
This Desktop Energy Seed Lamp is interesting. It uses old batteries as a power source. All of the batteries are put in parallel using two large metal plates and a jewel thief circuit (I prefer the rusty nail implementation though) is used to create the larger voltage needed to power the LED circuit. As long as the batteries all have about the same amount of charge left the circuit
Using a PicAxe microcontroller Eric from the Hacked Gadgets Forum coded an interface between the I2C Wii Nunchuck and some status LEDs. It would be trivial from this point to make the circuit activate relays or anything else imaginable instead of just a few LEDs. If you are interesting in playing with this project the code is available.
As we all know past knowledge narrows some of our creative thinking when attempting to solve a problem. This is not the case for the designs created by Bill Gross, he uses genetic algorithms to help him evolve solutions by having computers churn through billions of possible solutions while closing on optimal designs. He created IdeaLab to allow these ideas to come to life. Have a look at the
This PSP Sound Activated LED Light mod will have you grooving to the music. The Blue LEDs at the rear of this PSP has been added and hacked to move with the music. Have a look at the video below to see it in action.
