The making of my Tomorrowland LedHat

Last weekend I went to Tomorrowland 2013. I got the ticket months ago, in February. Ever since, I had been thinking about building something to stand out, something involving LEDs and an Arduino. As usual, I only decided what to build the day before the festival! I went to the mall and found a hat in discount. This would become my Tomorrowland LedHat 🙂

My little CNC shop

By now, you should already know one of my hobbies is flying RC machines, either quadcopters or planes. My quadcopters fly, but due to imperfections they aren’t locked in. I used to cut two plates out of aluminum using wood cutting tools, drill holes with my hand-held drill and screw it all together. Needless to say the arms weren’t always square to each other. I yearned for more precision. Continue reading

DIY GPS Logger

gps logger closedI need a GPS logger, don’t have one, don’t want to buy one, so let’s build one! I have all the necessary parts, so let’s start!

1. What do I want?

I need a device that logs location, speed and course on an SD card. I could use my Android phone to do this, but the GPS would drain the battery within the hour. So let’s build a dedicated device.

Because it won’t have a display, it needs to have a way to show if it has a GPS fix. It needs to run on a 3s lipo (11,1v) for as long as possible (preferably >12 hours), but I also want it to warn me when the battery voltage gets too low because lipo’s should never be discharged below 3v per cell (9v total) or they get damaged.

All that must fit in a waterproof case. Why waterproof? That will be clear in a future post 🙂
