They’re looking for the Higgs boson particle down in the LHC near Geneva, but recently a more modestly crafted particle accelerator was displayed at a Milanese department store, as part of Milan Design Week.
Well here’s another great video of the system in action, features 256 RGB LEDs in a 4-spoke system that apparently mounts into standard bike wheels.
There are 625 LEDs in total, with red, green, blue and white LEDs making some giant pixels, and the idea is to create something approximating video, via animation of the “RGB pixels”.
This month’s featured Gadget Master is provided by an old a favourite of the blog, Peter Griffiths. He has provuided all thde details necessary to build your own 5 x 5 LED cube. Construct your own programmed light display.
This neat little circuit provides 8 LEDs directly driven from the PIC along with a single mode control switch. The firmware described drives the LEDs with a 5 bit PWM signal providing each of the 8 LED channels with four levels of intensity; off, dim, mid, bright.
You can read the circuit schematics used in the modified waterproof solar torch, plus some detailed photos of the modification work.
Back in the days of the Berlin Wall, these Nixie tubes were manufactured by a now long-forgotten company. Fast forward to the twenty-first century, and Hans Summers found them stocked by an antique electronics part company.
Why is that you always test 48 bulbs before you find the bad one in a 50-light string? This simple circuit allows you to divide and conquer, greatly reducing the time it takes to find the bad bulb…
