MONOCHRON – Monochome display clock kit

Another very cool clock kit to lust after. I swear, if I had my way my room would look like Doc Brown lived in it…

The second clock kit from ladyada & Adafruit Industries, we present MONOCHRON!

We wanted to make a clock that was ultra-hackable, from adding a seperate battery-backed RTC to desiging the enclosure so you could program the clock once its assembled

• 128×64 LCD (KS0108) – we special-ordered the black and white display
• ATmega328 processor (we even stuck an ‘arduino’ stk500 bootloader on there too)
• Laser cut enclosure in black acrylic
• Beeping/blinking alarm with 10 minute snooze
• Battery backed-up real time clock (DS1307) keeps time even when power is lost for years
• European/US 12 or 24 hour time display as well as date
• Completely open source hardware, all firmware, layout and CAD files are yours to mess with
• Plenty of space for mods, a prototyping area for soldering stuff in
• Soothing animation of retro arcade style table-tennis for two

30 Best Practices for Writing HTML

Even if you are not a professional web developer and can only just cut and paste enough HTML to make a web page not totally suck these 30 tips are something that you should read. Lot’s of good practical advice, stuff like closing your tags and if you use inline styles an asteroid will strike you dead (not really but inline styles are still a bad idea). Read it and remember it the next time you are working on your magnum opus ‘Hello World’ page.

Bigshot: Focus on Cool!

I can only hope that this eventually makes it into the regular market:

A camera designed for kids can be much more than just a toy: it can serve as a powerful educational medium.  We believe that such an educational camera must have a radically different design from that of a typical consumer camera.   (a) It should be designed as a kit for assembly by students.  The assembly process should not only demystify the workings of the camera, but also expose students to various science and engineering concepts.  (b) It should include features that cannot be found in other cameras, allowing students to explore new creative dimensions.   (c) It should be low-cost, with the potential to serve as the basis for a scalable social venture.  Bigshot has been designed with these goals in mind.

The killer is the rotating lens board on the front. The lens wheel (or polyoptic wheel as it’s called)has three settings: normal, panoramic, and stereo. Normal is what you would think  it is, normal photo. The panoramic lens gives you a 72 degree field of view and creates a nice barrel distortion, and the stereo is a small prism that acts as a beam splitter to shoot a left and right image onto the sensor.Software that comes with the camera will adjust the distortion from the pano lens and create red/blue anaglyph stereo images when you use the beam splitter. Oh, did I mention that the camera can be powered by either a single AA battery or a few cranks on the built in dynamo?

It’s Halloween Again!

Over the years I have put together a few costumes for Halloween. Some took a few hours, some took days to build. The DIY Cricket bat and the robot costume have been my favorites:

Tony Stark / Arc Reactor Iron Man Costume of 2008

In 2008 I needed a costume fast. I had a party to go to in a few days and I was at a loss as to what I should make. I was half way through moving and money and time were both in short supply. I built this passable version of the Arc Reactor from the film ‘Iron Man’ in about three hours. As I wasn’t going to take it out from under the shirt it didn’t need to be near film accurate, just look the part. Ah, the magic of Hollywood…. I got dozens of great complements about it from the various parties I went to…”

Steel ‘Velcro’

Need to keep something heavy stuck to a wall? Fire proof Velcro sneakers for Iron Man? Maybe you just want a better way to hang your solid rocket boosters off your space ship. Super industrial strength steel hook and loop to the rescue!

Hook and loop fasteners have become commonplace features of both industry and households. However, they have one snag: they are too weak for many applications. Hook and loop fasteners made of spring steel have now been developed at the Institute of Metal Forming and Casting of the Technische Universitaet Muenchen. These fasteners are resistant to chemicals and can withstand a tensile load of up to 35 tonnes per square meter at temperatures as high as 800°C.

It’s called “Metaklett” if you want to try and find some.
