Intel Galileo is an Arduino on steroids. It comes with powerful Intel Atom processor running Arduino Linux distribution. It has most components that normal computer would need including USB host and client, Ethernet and Mini PCIe port that can accept many more peripherals like WLAN from laptop. And most important that it can be programmed from Arduino IDE. Øyvind have shared his latest weather station project built on this platform. He used popular DHT11 temperature/humidity sensor to get readings.
He wanted to log readings to SD card so before it was possible he had struggled a bit while he found proper format for it. FAT32 formatting did the trick. The code is really short and simple to follow.
This is really simple setup where you can drive three servo motors by turning potentiometers. It really takes few lines of code and minimal circuit setup, but if you look more deeply at this solution you can find many uses of it.
Simply you can build a remotely controlled rig which could do some fancy stuff. This can be a small robot arm which can be further extended by adding magnetic actuator and so on. If you need more degrees of freedom, keep adding more pots and servos.
Wearable electronics is commonly used in many areas. We are not talking about professional stuff like medical devices, but more hobby corner. But who knows where is a limit. Today anyone can assemble wearable projects with cheap building blocks that are mostly based on Arduino. AwesomePCB have shared his instructable on how to build a wearable OLED display covered with leather frame that blends pretty well on fabric.
He used small SSD1306 128×64 OLED display which is connected to small Attiny85 Arduino compatible board. Coin cell battery is enough to power it for quite some time. He paid some attention to details on how display is attached to leather piece and how this piece is snapped to clothes. You can do many fun stuff with the display including a temperature monitoring by attaching thermometer, it simply do rudimentary activity tracker with accelerometer or display current your mood with smileys which can be changed with single button press.
