Sandcasting at the beach

[mkb] sent in a video he found of [Max Lamb] sandcasting a stool at a beach in England. The material is pewter, or >90% tin with a little bit copper and antimony thrown in for good measure. While we’re sure there will be a few complaints from environmentalists, it’s still a cool video to see.

Your project needs an OLED display

Here’s a Kickstarter for a tiny 96×16 OLED display. Connect this thing to any I2C bus and you get a 15×2 character display (or a graphic display if that’s your inclination) very easily. Thanks to [Chris] for sending this one in.

Here’s one for a larf

[Ryan Inman] is suing 20 companies because he got mercury poisoning from vacuum tubes. Read that last line again. Most of the companies that sell antique/repro/hard-to-find components like Angela Instruments, Antique Electronic Supply, and even eBay are listed as defendants in the case. This might put at least one company out of business even though they never sold [Ryan] a vacuum tube edit: they did sell him a neon bulb, and courts are generally idiotic when it comes to technological issues. It’s hilarious and sad, so we’ll keep you updated if we get more info.

Nostalgia, the pain from an old wound

The Adafruit blog posted an excellent piece on the Apple ][ game Rocky’s Boots, an educational game from 1982 that teaches kids how to connect logic gates. You can play this game in your browser, but we’d like to hear our stories of ancient video games that teach you engineering concepts like The Incredible Machine or Widget Workshop. Leave a note in the comments if we’re leaving any out.

A question posed to the community

A company is giving away credit card readers that plug into the headphone jack of an iDevice. [J Smith] writes in to ask us if anyone has gotten one of these and opened them up. Like [J Smith] we’re expecting something a repeat of the CueCat where free hardware is opened up to everybody. If you’ve done a teardown of one of these card readers, send it in.

3DS homebrew

[Mike] sent us a link to [neimod]‘s Flickr photostream. It looks like we’re on the cusp of tearing open the Nintendo 3DS for homebrew apps. Someone who uses this much hot glue must know what they’re doing, right?
