This Instructable will be about designing a music player from using various building blocks. You will understand the communication between the microcontroller, memory, computer, LCD display, RTC, IR remote, and the music file decoder. I will try my best to to teach you in a way so that you can design your own projects using […]

I really like nixie and numitron clocks, but I never worked with them before. So I decided to give it a go. I choose numitrons because of 2 reasons: first of all nixies need a higher voltage than numitrons to work. Nixies need around 170V DC and numitrons only 4,5V so they are safer to

The internet hosts lots and lots of online radiostreams, most of them with a certain theme, ranging from old time classics to Tibetian riverdancing. I must admit that I love to listen to them while I’m building stuff, as I can choose the music I like without listening to the same cd’s over and over

Nokia manufactures a wide variety of cell phones and many of their cheaper phones contain simple LCD’s which may be used in microcontroller projects. There is one particular LCD model that is used in a wide variety of their phones and is often referred to as simply a “Nokia LCD“, or “Nokia 6100 LCD”. I

Unless you’ve been living under a digital rock for the last few years, or just simply aren’t interested in flashing lights, you’ll already know about the awesomeness that is the BlinkM from ThingM. It’s a very small PCB featuring a high power LED that responds very easily and cleanly to commands you give it. Devices like BlinkM’s

This is a business card that will type out some text when you plug it into a USB port. It uses a ATtiny85 microcontroller with V-USB based code to emulate a keyboard. The typing is triggered by the CAPS LOCK status LEDs being toggled 3 times. This instructable will focus on using CadSoft EAGLE to

As I get more serious into my electronics hobby, I need to work with more SMD components. Some component packages are very difficult or impossible to solder with a traditional soldering iron. To solve this problem, I decided to hack a toaster oven to become a reflow soldering oven. Basically, to perform reflow soldering, solder

Update May 4 2012: I am still working very hard on version 3 of Picopter. The new version’s hardware is already done. There are new 3D printed motor holders. I’ve done some measurements with regards to mass and radio spectrum. I’ve posted stuff to http://www.frank-zhao.com/picopter_forum/index.php including the new design files, so take a look. Update Feb
