Bomb Timer Movie Prop

A friend of mine was asked to make a prop that looked like a home made bomb for a movie that was being produced. I helped out by designing and building the countdown timer display circuit. As you can see it has a bit of a home made look to it, which is what the director was looking for to fit within the context of the story.

This project used parts I got from Digikey and Sparkfun. It’s built on two separate pieces of perfboard and uses only two ICs to operate the display, a LED Display Driver (MAX7219) and an Atmel ATTiny4313. Click continue reading for more photos, descriptions, and a video of the finished timer!

Square Inc. card reader keychain (DIY)

I just got my Square Inc. card reader in the mail. Basically it’s a little device that can be plugged into the bottom of an iPhone or iPod touch. It allows you to swipe credit cards through it, enabling you to accept credit card payments anywhere! I was trying to decide where I was going to stash it so that it would always be with me, it’s too big for a wallet, but it would work on my keys! However, I didn’t want it to be attached to my keys when I was using it, it needed to be releasable. After pondering how to do this I realized it’s already made to be attached and released. With that in mind I went looking for a spare female headphone jack.

I found an extra 2.5mm headphone adapter, and after a little dremel work to chop the top off, and one small hole I had a perfect quick release Square pay card reader on my keys. Took all of five minutes once I found the adapter. Now I can accept credit card payments anywhere (Lookout world!).

Extendo Bikes

  • Back in the day we made some crazy bikes out of other bikes. At first we did it just for fun but after it caught on we started making them so that we could ride manathons with them. I think so far we have done three marathons, first the Los Angeles Marathon in 2004, then the 2004 Long Beach Marathon, and finally the 2005 Long Beach Marathon. We had a great time at all of them but the Long Beach Marathon is way more fun course wise. So here is a quick look at the crazy Exteno Bikes.

DJ Cabinet

  • Here at the X-INfERNO we like to jam. As anyone with a garage band may know, there is a lot of equipment involved with making all this happen. We have guitars, drums, vocal mics, instrument mics, effects processors, recorders, players, amps and cords galore and they all need to be connected together by some physical means to get everyone outputting and sounding or recording right. Well since a lot of these things are 19″ rack mount, I thought it would be great to have a cabinet on wheels to organise everything in. It would be easier to move around and take to gigs and such. So that’s how this project started.
