3d printed nes portable looks fantastic and contains no hot glue

SONY DSC

[Parker] emailed us today to show off his latest NES portable build. This time he's using the standard "top loader" NES instead of the typically used NES on a chip. This is pretty cool since the NES on a chip has compatibility issues with some games. For the screen, he uses a common PSone screen with a slight power modification. From the factory, the screen takes 7.4 V and converts it down to 5V … [Read more...]

Building sensors for the Scratch programming language

sensors-for-scratch

[Kevin Osborn] is making it a bit easier for young programmers to write programs that interact with the physical world. The device he's holding in the picture is an Arduino based accelerometer and distance sensor meant for the Scratch language. Scratch is a programming language developed at MIT. It has kids in mind, and focuses on graphical building blocks. This can make it quite a bit easier … [Read more...]

Retrotechtacular: Shakey shows off robotics innovation from 1972

shakey-1972-robotics

In this installement of Retrotechtacular we're taking a look at Shakey, a robot developed between 1966 and 1972 at the Stanford Reserach Lab. This was a glorious time when students had long hair but still wore long sleeves and ties to do their research. The robot is actually communicating wirelessly with the PDP-10 computer which handles the processing. No computer monitor is used for … [Read more...]

Giving a Powerpoint presentation with an Apple ][

A2

When [Vince] saw a coworker give a presentation with an iPad, he thought to himself what a tremendous waste of computing resources he was witnessing; an iPad is just as powerful as an early Cray supercomputer, and displaying slides isn't a computationally intensive task. We're assuming [Vince]'s train of thought went off the rails at that point, because he came up with a neat way to give a … [Read more...]

Cheap wooden hexapod frame greatly reduces cost

Make-a-real-cheap-hexapod-

[Balline] really wanted to play with a hexapod but found the cost to be prohibitive. Being a mechanical engineer, he was able to fairly quickly come up with a stable 3 servo design that would allow him to experiment with the platform. He chose to use wood as the construction material to help reduce costs even more.  As you can see in the video after the break, his design gets around fairly well. … [Read more...]

Electric Imp connects projects to the Internet

imp

If you're planning a build that communicates wirelessly to that 'Internet of things' we've been hearing about, you might want to check out the Electric Imp. This tiny little card connects your project to the Internet without all the hassle of configuring an embedded wireless device. Inside the Electric Imp is a good bit of hardware: an ARM CortexM3, and an 802.11b/g/n wi-fi module that will … [Read more...]

Snake-like robot can roll around in a ring

robot-snake-rolls-as-a-ring

A lot of 3D printing and a many servo motors went into this snake-like robot, and it's only about half of what [Toby Baumgartner] plans to accomplish. In this orientation the snake is rolled into a circle, and apparently some special movements in the segments allow it to roll around like this. He compares it to a tank tread without the tank attached to it. Notice that each link is rounded on the … [Read more...]
