On Gadget Master we like to cover bike gadgets, and many of the ones that pop up these days are safety related – a growing market sector given the huge rise in enthusiasm for social cycling that followed the successful 2012 Olympics.
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.
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.
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.
From Alan Parekh’s tome of knowledge, comes the stair lighting kit. The lighting control unit is microcontroller based, so a self-contained computer controls the device. The stair lights are connected to the control unit and an Infrared transmitter and receiver are utilised at the top and bottom of the staircase to generate a beam of invisible light. When a person ...
That’s why he created a 40-LED night light to make sure he could see and be seen on his bike. Bill set up a 555 timer IC to generate a continuous on/off timing cycle to alternatively flash two groups of 20 LEDs. His night light operates on four AA batteries, which will keep the road ahead nice and bright, even ...
If there’s one thing we hate more than track work on the Victoria line, it’s not being able to hear the damn phone when it’s ringing. (Admittedly, this is probably due to years of listening to music at deafening levels. Yes, we are those people you hate on the tube who play their iPod so loud you can hear the ...
