The LM317 Regulator Mini Lighthouse LED Circuit

Do you know why this project named as “Mini Lighthouse LED circuit”? It’s because the LED circuit has a shape like a lighthouse and that’s the reason it got the name here! Basically, this is a simple “lighthouse” that when it’s powered up, it will rotate the beam around the 12 LEDs. This Mini Lighthouse LED Circuit is a very useful tool, especially for a model railway. For your information, this Lighthouse has several interesting features. The first feature is a full size ICSP connector, while the second is a socketed DIP version of the PIC12F683. Those 12LEDs is the maximum numbers of you can charlieplex from four tri-state pins. The PIC12F683 is an eight pin device that has five GPIO plus the MCLR pin, where it can be used… Continue reading

DC Boarduino – A Clone Will Make It Good

Did you ever have this experience before? You’ve been struggled to use a solderness breadboard with an Arduino, and you know how annoying it can be. Now, you can dump all of the frustrating into the dumpsite with this new DC Boarduino. This DC Boarduino is a clone that can works with the latest Arduino software. The assembly is so easy to operate and well documented.
