Kickstarter is dead, long live… who? & how?

Last year, Kickstarter, concerned about the public thinking they were a shop, made some changes. http://money.cnn.com/2012/09/27/technology/startups/kickstarter-products/index.html In short, in September they banned technology projects from running without a working prototype, and they banned the offer of multiple items as a reward.   That these changes have killed the Kickstarter technology arena for (some) new starts […]

School shooting mitigation system

The news of another school shooting by a disturbed but coldly calculating killer leaves us all sad. Apparently the school had a ‘new high security system’ but it obviously wasn’t. Though the risk of a shooting is low, the severity is incredibly high, so, much like a bombing or chemical attack, it is worth considering […]

‘That’s obvious – why didn’t I think of that?’

So New Scientist reports that a team have invented ‘white smell’ to join the ranks of ‘white noise’ and ‘white light’. ‘White’ here simply means ‘every part has the same relative strength. So with light, that’s lot of red, a bit less green, and blue somewhere in between, which your eyes read as ‘white’. With […]

Anti-dazzle systems for car windscreens

Looking at some cheap digital sensors yesterday. I am amazed at how cheap the things that were just a few decades ago ten of thousands of pounds. At BAE I was part of a project that was worth millions, yet now that same functionality is embedded in a little unit costing $50, alongside the built-in […]

How can you tell the difference between hazard lights and indicators?

No, it’s not a joke. When driving, cars and the like are often indicating or have their hazard lights on, but it is frequently impossible to tell the meaning, as usually only one side can be seen. The older car had a mechanical flasher relay, using a simple but robust metal strip which heats up […]

Storage solutions – none are perfect

Spent the last 2 days clearing stuff out. There is almost room to get into the shed, though the basement remains stubbornly damp and packed full, and we cleared a huge volume of stuff from the ‘attic’ which mostly being cardboard and boxes from purchases burned rather well. The aim is to be able to […]

@EMFcamp – ElectroMagnetic Field

To say I feel re-inspired after EMF is an understatement. Oh, the plans I have! To see nearly 500 people at a camp where the goal was to have lots of people doing cool things with technology and generally having fun with teaching others how to do similarly cool stuff was uplifting. Shouts out to: […]

Quick Dremel hack

Here’s a very quick hack for the Dremel battery tool. Grab your vice. I’m using a hefty machinists vice. Take a thin bit of steel suitable to fit between the jaws. This was off an old PC case, 1mm thick. Make a 20mm hole to fit dremel through, then bend to match width of tool […]

Projection lamps cost more than projectors

As the projector lamp is reaching the end of its life, I looked up the cost of a new bulb, only to find that they are over £200. Plus VAT. And the projectors, new, are around, er, £200 plus VAT. True enough, the £200 projectors aren’t quite as good as the frankly brilliant bargain projector […]

Floating packing peanuts

Someone must have done this, but I found nothing with a brief google aside from an idea for bubblewrap on www.halfbakery.com . Take a standard packing peanut making machine (I’m assuming there is such a thing) and put helium in, rather than air. Once the polystyrene has expanded, in theory at least the helium will […]
