Free-form Christmas ornament

Here’s [Rob]‘s free form circuit that’s a Christmas ornament for geeks. It looks great, but sadly isn’t powered through a Christmas light strand. It’s just as cool as the skeletal Arduino we saw.

Prototyping with flowers

Well this is interesting: protoboard that’s specifically made to make SMD soldering easier. The guys at elecfreaks went through a lot of design iterations to make sure it works.

We’ll call it Buzz Beer

The days are getting longer and cabin fever will soon set in. Why not brew beer in your coffee maker? It’s an oldie but a goodie.

Christmas oscilloscope

With just an ATtiny and a little bit of  futzing around changing the coefficients of a partial differential equation, you too can have your very own oscilloscope Christmas tree. Don’t worry though, there are instructions on how to implement it with an Arduino as well. HaD’s own [Kevin] might be the one to beat, though.

So what exactly does a grip do?

You know what your home movies need? A camera crane, of course. You’ll be able to get some neat panning action going on, and maybe some shots you couldn’t do otherwise. Want a demo? Ok, here’s a guy on a unicycle.

    That flower protoboard looks absolutely amazing. I’m going to have to get a hold of one *very* soon. Will HaD be kind enough to apply for a sample and do a review?

    Ah the 2230. My first high persistence phosphor coated love.

    For a second there, I thought the SMD protoboard was a magnetic core memory shield for an Arduino. Now THAT would be sweet..

    I love the free-form ornament. I was thinking of a simple little led blinkey ornament with a 555, maybe with a button or two to play with or something else fun like that.

    In my experience, a grip has little to nothing to do with camera work. They’re most often found holding onto bounces and configuring lighting needed for a shot. Also, we laid and removed track for the dolly.

    Most camera crews I worked with had their own assistants to deal with cranes and actually pushing/pulling the dolly.

    The only time I was involved with camera work on a set was when we were short a set of hands, and I happened to be there at the time to fill the roll.

    I did a turtle graphics version of the johnengineer project: http://wa5znu.org/2011/11/arduino-2500/

    I gotta agree with the first comment. The Flower Protoboard looks incredible. I’m really impressed by the savings in solder and how they worked out the issues. Really nice work.

    I do not believe you can make an Arduino with this. It appears that it is a .1″(2.54mm)pitch. Atmega328’s TQFP package has a .8mm pitch. You can easily buy a TQFP breakout board ~$5
