Project Sea Rendering Autonomously Renders Sea Bottoms

[Geir] has created a pretty neat device, it’s actually his second version of an autonomous boat that maps the depths of lakes and ponds. He calls it the Sea Rendering. The project is pretty serious as the hull was specially made of fiberglass. The propulsion is a simple DC motor and the rudder is powered by an RC servo. A light and flag adorn the top deck making the small craft visible to other larger boats that may be passing by. Seven batteries are responsible for all of the power requirements.

The craft’s course is pre-programmed in Mission Planner and …read more

The Biggest Game Boy Ever?

Feeling nostalgic? Miss the solid feel of an original Nintendo Game Boy? You could smash a window with one and keep playing Pokemon the whole time!  Well, [Raz] was, and he built what might just be the biggest Gameboy ever. Gameboy XXL: The Texas Edition.

Actually, it was commissioned for a Belgian music festival called Nintendoom — picture video game music + rave. Anyway, the organizer thought it would be so cool to have a giant functional Game Boy, so [Raz] got to work. He made it out of 10 square meters of 3mm thick MDF, which he laser cut …read more

Need Timing Diagrams? Try Wavedrom

When working with anything digital, you’re going to end up reading or writing a timing diagram before long. For us, that’s meant keeping (text) notes, drawing something on a napkin, or using a tool like Inkscape. None of these are ideal.

An afternoon’s search for a better tool ended up with Wavedrom.

Just so you know where we’re coming from, here’s our list of desiderata for a timing diagram drawing solution:

  • Diagrams have a text-based representation, so their generation can be easily scripted and the results versioned and tracked throughout project development
  • Command-line rendering of images, because we like to

LED Matrix Plus Geiger Counter

A lot of projects get made because someone just has the parts lying around. In this case, [Ed Nisley] got given a nice 8×8 RGB LED matrix, and needed something to display. [Ed] details the transformation of stuff-lying-on-the-desk into a unique matrix display for a Geiger counter (which he also presumably had sitting around somewhere). The result is a lightshow that’s as random as radioactive decay, and that’s pretty darn random.

The first post covers the hardware layout. It’s build on protoboard, but ends up looking a lot nicer than our projects because [Ed] spent some time hiding the shift-register …read more

New Cable-Based Vise Improves Woodworking Workshop

We are all aware of the typical wood shop vice, the type that is mounted underneath the workbench and takes forever to open and close by continuously spinning a large handle. These vises normally only open several inches due to the length of the operating screw. They are also not very wide because a canter-levered wide jaw would provide less force the further away it is from the center-mounted operating screw.

Wood worker [Andrew] wanted a very versatile and large vise for his shop. It needed to be wide, provide equal clamping force along the jaw and be able to …read more

Robot Camel Jockeys

You might think we’re sinking to lowest-common-denominator, click-bait headlines like the rest of the online press. We’re not. The New York Times Video Notebook series has a story on camel racing that you’ve just got to see in the video after the break.

Previously, the camel races in Abu Dhabi had used small children as jockeys because they’re lightweight. Unfortunately, this lead to illegal trafficking of small children, mostly orphans. That won’t do. So they came up with a technological solution.

Strap a cordless drill with a purpose-built whip in the chuck onto the back of your camel. Add a …read more
