Adafruit wearables electronics videos and adafruit daily mails

The other day I bumped into this video on youtube and thought it’s worth spreading it. In these videos Beck Stern walks through some recent news on wearable electronics, in this episode her co-host is Collin, who’s always funny 🙂

Other than this, Adafruit has started the daily mail programme, where you can subscribe for a “one-liner note along with an image per topic”-sort of mails. It goes well with the morning cup of tea (or coffee). If this got you interested, go check it out:

Clay skull figure with electronics inside! Part 2

Last time we made a clay figure with electronics embedded. This post includes the wiring layout to animate the figure with an Arduino + code.

The idea

So since the skull I made in part 1 had electronics inside but without any means of actual control, I had to do something about that. Needless to say, this skull needs some effects. Let’s see what we can cook with:

Outputs: left eye LED, right eye LED

Inputs: micro pushbutton, potentiometer

Not much…

What should this skull do?

  1. LEDs glow with fixed intensity (intensity should be configurable)
  2. LEDs fade in and out (speed and max intensity should be configurable)
  3. LEDs blink in an  alternating fashion (speed and max intensity should be configurable)

How about something like this?

Clay skull figure with electronics inside! Part 1

You know I love simple electronics.

Unfortunately the biggest dilemma faced with these projects is about the case, at least for me. Seeing my girlfriend make very nice artistic clay figures I wondered how I could give them a little bit of life, alas the idea of embedding electronics emerged!

I included some LEDs, a potentiometer and a small pushbutton within this clay figure to make cool effects and to serve as an unusual control device for something.

Ingredients:

  • air drying modelling clay
  • 2 orange LEDs
  • 1 mini pushbutton
  • 1 potentiometer (I got mine from the infinite servo post)
  • female pin header
  • scrap ethernet cable (available at your nearest System Administrator)

To infinity and beyond…with RC servos!

Do you like RC servos? I hope so because we do. Especially those with metal gear inside for their lifetime and reliability. We have a few TowardPro MG996R servos so I’ll demonstrate the whole process of making a servo able to turn forever with one.

To see where we are going let’s take a quick look at Ms. Piggy dancing around on the servo.

Beaglebone + thermal sensor with ROS

Robots self testing

As we build more complex robots we need more feedback from them to know what state they are in. In my case I want to know some temperature information about my rover. These things are the motors, the outside environment, and the battery temperature. For this purpose, I want to create an Arduino thermal sensor. Later it will be only an Atmel chip with the sensors but for prototyping and developing the Arduino is the best solution.
The central computer on the Rovers will be Beaglebone. So after I create the thermal sensor, I need to make the communication between these devices. If that is done, the only thing is left to make the ROS package. I have chosen ROS because in the near future I want to make more sensors and ROS is ideal for information distributing.

Cheat sheet bonanza

Lately I’ve been working a lot with Atmega328P on a custom breadboard and found it troublesome to always look up the pdf on my computer so instead I put together a nice cheat sheet and hung it up on the wall so I can check it any time I feel like it.

Enough talk, here’s the stuff:
