Rube Goldberg machines are always a fan favorite around here. They truly embody the concept of over-engineering, and are an entertaining departure from what we normally cover on Hackaday.

Back in February, engineering students from two on-campus professional associations at Purdue University teamed up to construct a
Their entry in the Purdue Regional Rube Goldberg Machine

Contest not only won them the regional title, but also potentially put them in the books as creating the most complex device of its nature.

Their contraption was dubbed “The Time Machine” and acts out events in our planet’s history. It starts with the big bang, moving through various other time periods, including the stone age, ancient Egypt, and the medieval era. It also makes several stops in more recent times, including World War II and the Cold War, before self-destructing at the Apocalypse.

All told, the machine incorporates 244 steps to water a plant, which is 14 more than the previous record holder. Continue reading to see a video that highlights some of the machine’s more interesting features, and be sure to
It’s been nearly two months since the official entry portion of the 555 timer contest came to a close, and the judges have been busy poring over the 200+ entries since. Now that the votes have been tallied, it’sThe results will be live streamed this evening at 9pm Eastern, and you can watch the results

awards given out this evening, highlighting the most complex, most minimalistic, most artistic, and most useful 555 creations. There are also “Best in Show” and “Best Under 18” awards up for grabs, the winners of which were selected by celebrity judges Forrest Mims and Hans Camenzind.

The show will definitely be worth checking out – we’ll be there at 9pm sharp, see you there!
If you want to take a look at some of the 555 Contest entries we featured throughout February, check these out:20 is only 10 days away! Great, what the heck is Ludum Dare? Well its

only the most awesome video game creation contest on the internet, thats what. While originally for the hardest of the hard core, it has recently been split up into 2 events so everyone gets to have some fun.

The Jam is pretty relaxed in the rules. Lets say you and 4 buddies want to make the ultimate zelda remix using fan sprites and free music. This is where you want to be. Its there to give people who want to join in the fun but not make serious obligations.

The Compo is the real deal for those who are insane, or really good. You are given a theme at the start of the contest and 48 hours. You must then work solo and create all original content to use within your game. You can however use premade frameworks, game engines, libraries etc to accomplish your goal, but if you really wanted to you could make a 3D engine with brain fu*k during the competition. (though I would not advise it)

Prizes include internet bragging rights, and quite possibility the best darn feeling of accomplishment possible IF you manage to come up with some form of game, based on a voted theme, by yourself, in less than 48 hours.
