Santa-pede Contest Winners

February 28, 2011 by Caleb Kraft 15 Comments

We received several fantastic entries. We laughed, we cried, we stared at our monitors in confusion, it was fantastic. Now we’re here to announce the winners of the Santa-Pede contest.

If you recall, the rules were pretty simple. Aquire a dancing santa (or other holiday dancing annoying toy thingy in the same fashion), tear it apart, build something that walks out of the pieces. We were aware that most of these have a very similar setup with one or two servos and a bit of plastic. That way everyone has a similar starting point. We were amazed at what was done with so little.

Keep reading to find out who one each of the three categories: Most over-done, best walker with no extra parts, and best presentation.

LED Dog Collar, Christmas Edition

February 11, 2011 by Caleb Kraft 11 Comments

[Aaron] says in our comments that he also made an LED dog collar. This Christmas themed dog collar uses an ATTiny13a and a hand full of red and green LEDs (28?). While the animations aren’t as complex as the collar we posted earlier today, we though you might enjoy this one as well. From the description, we think that the LEDs simply fade back and forth between red and green. We think that [Aaron] did a great job. He has included the source code and schematic on his site, but sadly there’s no video of this collar in action.

The Plant Whisperer

February 11, 2011 by Caleb Kraft 14 Comments

[Jeff], fully acknowledging his inability to keep plants alive, has designed a system to help him out a little bit. The “Plant Whisperer” monitors water levels and notifies him if the plant needs attention. Actually, it notifies him either way. The plant whisperer uses real time text to speech to say one of several pre-programmed things, either proclaiming its happiness or requesting more water. He’s using a parallax propeller for the job as he says it is capable of handling the real time text to speech. We realize this is overkill, but we absolutely love it. The only improvement we would want would be to possibly use a pre-recorded voice for more clarity. You can see a video of it in action after the break.

How The Arduino Won? This Is How We Can Kill It.

February 11, 2011 by Caleb Kraft 146 Comments

[Phillip Torrone], has written a piece over at Make entitled “Why the Arduino won, and why it’s here to stay“. While boasting that the Arduino “won” at roughly 100k units in the wild sounds decently impressive at first, lets just ponder for a moment how many bare AVR chips there are out there in home-made projects. Kind of makes 100k sound small doesn’t it. However, if you look at their definition of the Arduino, targeting fresh and new people to microcontroller projects, that changes things a little bit. That number suddenly starts to seem a little more important if you re-word it as 100,000 new beginner hackers. Sure, they’re only tweeting toilet flushes and blinking lights, but they’re excited and they’ve tasted blood.

[Phil] goes on to talk to manufacturers on how to “beat” the Arduino. He lists features that would help push someone onto a new platform instead of the Arduino. This, is where I think we come in. We can kill the Arduino.

The CIA’s Amazing Bots

February 10, 2011 by Caleb Kraft 57 Comments

When you have a virtually unlimited budget, you can pull off some amazing things. This has become most evident recently as the CIA has been showing off some of its old tech. That dragonfly you see above is near life-size and actually flies. They hired a watch maker to build a tiny internal combustion engine to run it. That alone is pretty amazing, but this thing was actually flying in the 70’s. Upon further inspection of the wings, we actually have no idea how this sucker is supposed to fly. Despite our skeptical viewpoint, you can see a tiny clip of it flying after the break. You can also catch a video of “charlie” the robot catfish.

RGB “Tilty Cube”

February 10, 2011 by Caleb Kraft 20 Comments

[Ben’s] introduction to microcontrollers was this fun little gift he calls the “tilty cube”. It is an acrylic box with 3 LEDs mounted inside that changes color based off of how you tilt it. Sounds like a fun toy, and a good project to learn with. [Ben] chose the PIC12F615 as the brains and laid it all out on a perfboard. Since this was his first microcontroller experience he had to learn how to blink the LEDs, then figure out PWM etc. Though there is no video of the project in its finished state, since it was given away as a gift, we assume he figured it out pretty well. He does state that the LEDs are dimmer than he had hoped and offers some thoughts on how he would do the entire project better next time.

The Joy Of Forums

February 10, 2011 by Caleb Kraft 15 Comments

[John Park] over at Make posted a short story about coming home from vacation to find his espresso machine non-functional. After beating his head against the wall for a while he joined a forum and posted a video. As has happened so many times, another user had seen this exact issue and was able to send him in the right direction.

We realize that this is just a simple capacitor replacement, though we understand his frustration, the original looks perfectly fine. The point here, is that there is usually someone out there on a forum that has experience with whatever your problem is. So don’t waste any time, go join the most awesome forum on the planet and get hacking!
