Clean Up the ImageOpen up the image in your editor of choice. We're going to have to make some changes.1. Turn the saturation all the way down to get a black and white image.2. Adjust the levels for maximum contrast.3. Invert the colors. What you want...
Analog 4 is the Temperature sensor input.The TMP36 outputs an analog voltage that represents the temperature.A simple formula gives the temperature based on voltage:float celsius = ((voltage * 1000) - 500) / 10;
In order to add wireless access point capability to your media server, you need to install hostapd (hostapd_8192cu from AUR if your wifi dongle is based on a rtl8192cu chipset) and dhcp. If you have installed yaourt as stated in an upper Build Instruction,...
1. The first thing I did after coming up with the idea is to find a way to control 3 sets of 8 leds on each with a minimum amount of wires. I found an article that talked about shift registers and went ahead and ordered a few to try them out. following...

Solder the amplifier circuit, dead bug style.Solder the speaker output of the Bluetooth headset to the 100 Ohm resistor. Cut the heat shrink tube to cover,Solder the resistor now to pin 2 of the TransistorSolder pin 3 of the Transistor to the Power connection...
Greetings fellow Enthusiasts Let me introduce myself. I'm Bones MacGyver. I like to make sparks.I'm going to do my best to help out the community with their battery woes.By no means am I a battery expert. But I have used and abused MANY Ni-Cd cells (and...
Winding the inductors is easier than you might think! I used about 4 feet of 18GA Magnet wire to wind the inductors for this particular power supply. Each inductor has ~30 turns on it for an inductance of about 90uH. If you don't have...
In this step, how the Arduino shield stack gets assembled, and how to wire your wave shield will be discussed. If you remember the note from the top in step 1, You hopefully used stacking headers to build your wave shield. If you didn't,...
