This will be an ongoing post to be updated as the questions roll in, but here’s the results so far:

First question – earning £10:

Laura-Mae’s entry. A guess-the-picture style one. It stumped me, and so I gave up. How am I supposed to know what a part of an iron looks like when I don’t even know what an iron is for? Seriously…

£10 goes to Comic Relief for this one. Well done.

TL;DR : Ask me questions, stump me, get money donated to your charity of choice.

Right, Thursday, you tricked me again. For all of this week I’ve been getting the days wrong. Wednesday was my Thursday, but once I realised that it wasn’t Thursday I relaxed… for two days. Next thing you know it’s Friday. Excuses excuses, I know, but I slept yesterday. So today is the new Thursday, for this week only. Exclusive news, I know.

On with the question part. I’ve decided to have a bit of a remix for this week – you get to ask me the questions. I know, weird huh. The idea is that you ask me a general knowledge question in the comments, and I have to answer. If I don’t get it right first time you get to choose a charity and I donate to it. Of course this will be limited to the same £20 limit, maybe £25 if a particularly creative question comes along after the £20 is spent. There will be three (or four) chances to get your charity choice donated to. The first question I get wrong will win £10 for the charity of choice, while the second and third (and fourth?) questions will get £5.

Preferably you’ll give me questions in the form of pictures or general knowledge. So please no nonsense questions of what your uncle’s best friend’s co-worker’s favourite band/colour/food is.

So go ahead, give it your best shot, and make me look stupid. It’s all for charity, after all. :D

This week I’ve decided to forgo the question and instead donate directly to BBC Radio 1′s Red Nose Day event. For those who are unaware (and haven’t clicked the link yet) Scott Mills will be trekking across 100km of desert in Kenya along with Lorraine Kelly, Kara Tointon, Olly Murs, Ronni Ancona, Dermot O’ Leary, Peter White, Nadia Sawalha, and Craig David. Yes, Craig David. If nothing else it’s worth donating for Scott’s endurance and willingness to spend 5 days with Craig David.

The main focus this year is on supplying people with vital eye surgery and treatment that they would otherwise be unable to afford. There will be one person treated for every £5 donated. Just £5 could save someone’s sight. Personally I’ll be donating the usual £20 towards the cause this week. In 2009 Radio 1 raised £3,326,142 when Chris Moyles, Gary Barlow, Ferne Cotton and a few others climbed Mt. Kilimanjaro as a sponsored event. The donation lines were opened early this morning, and within 30 minutes the donation figure had already gotten to over £33,000. Let’s help get that figure up and try to beat the 2009 record. It’s only £5 to save someone’s sight, and their livelihood. Dig deep. :)

And yes this decision to skip the competition this week was partially due to me forgetting to prepare anything for it. But shh! :P

And yes I know there’s still a month to go until Red Nose Day, but the event started on Radio 1 already so this prompted me to do this now. :P

This is where I’d normally post an image of a donation page showing that I’ve donated. Unfortunately right now I’m having problems finding a way to get the money to the charity chosen by this week’s benefactor, Gerrit, who correctly answered that the circuit was a 555 timer IC in astable mode. However, as a bonus for including the correct frequency in the answers given, I’ll be putting an additional £5 down on the donation. So well done Gerrit, and thank you.

The charity Gerrit has chosen is Vision K found over at http://www.visionafrika.com. A local charity in the township Kayamandi located at the edge of Stellenbosch in South Africa. As much as I’d love to encourage people to donate, if my experience so far is anything to go by, it’s tricky. But hey, if you can, give it a go. I’m sure any help will be appreciated. I’ll post an update once I’m successful in donating myself.

That’s all for now, until Thursday again. Now, back to trying to find a way to donate that money…

I thought this would be a tricky one for you, but those who would know would know straight away. Yes, this is another of my could-go-really-fast-or-not-at-all specials. After that is said, I guess it’s time to give you a hint. This’ll be good.

R1 = 10kΩ

R2 = 100kΩ

C = 1μF

Low = 0.693 * R2 * C

High = 0.693 * (R1+R2) * C

You still need to tell me what it is though and what it will do. ;)

£20 to the charity of choice of the first person to answer correctly. I might even have a bonus question for an extra £5 too. ;)

[Insert interesting opening banter statement here, with a witty anecdote and funny punchline]

As you can guess, I have nothing interesting to say right now. So, on to the question:

Given 5V on the power rail, what would this circuit do?

Once again, £20 to the charity of choice of the first person to give me the answer in the comments below. Good luck. =D
