Nope, still confused. :confused: What I'm gleaning using my own neural processing network, is that the Christina project is some form of neural network that is intended to take inputs from many places, spot patterns and offer advice to the government in particular about running the economy...

Yes, just been reading the nuclear pages...very good, nice focus on the numbers rather than the FEAR! Oh I'm not so sure about hydro, surely we can just soop up some of the current ones by replacing the water with something heavier, say molten lead!?! :D . I'll have to read about this...

Well it does in a way. I suppose what I was ineffectually getting at was that demand regulation would be a big problem for huge fleets of battery powered vehicles. Our current off-peak hours during the night when the hydro schemes pump up the water, would then become as high (or higher) than the...

Another urgent question now as we move towards electric cars of one type or another is where is the extra electricity going to come from to charge them. Not only is there the whole nuclear/wind/wave/solar/coal/gas etc debate. There's also the demand/supply management problem, the cables etc...

I believe the 2009 edition still requires you to pedal :( but David did say that a simple mod was possible to get it back to throttle control :).

Try: Rayshack Ltd Tel: 020 7278 4145| 34, Chapel Market, London, N1 9EN for the fuses. Cheers Steve

Indeed, strangely though the frame itself is quite big (long), in fact once you have the seat height sorted out it should fit larger framed people very well, so I'd encourage you to try it. Maybe David (Wisper) could offer some nice long seat posts as an option? (Or take one to Presteinge for...

Yes, 6ft 4 might be pushing it on the Wisper even if you replace the seat post. I'm 6ft and am using a replacement 400mm seat tube. I'm only an inch or so from the safe limit of the seat post. Deffo would need an extended test, preferably with the bike set up correctly (i.e. longer seat posts...

Oh yes, John Birkett's is still open, unchanged in years. The shop window is a treasure trove of fascinating gadgets of yesteryear.

Well after translation to English, I can see that you have a problem with your fuse. Basically fuses come in different physical sizes i.e. lengths. and also in different "strengths" which is measured in Amps (the symbol is A). Most likely a 20A to 25A (20-25 Amp) fuse will suffice...

Yeah, but there's something comforting about those old analogue meters.... :)

Everytime I go home to Lincoln, I always spend a few minutes gazing into the windows of John Birkett's electronics shop. Crammed full of old services gear from Lancasters, Spitfires, Vulcans etc etc. always wondered who bought it! Anyone for a WW2 altimeter? :rolleyes:

I see what you're saying RE: the AC vs DC measurement... I'm not sure coz I don't have the meter in front of me, but I think that Maplin meter does notice the DC and takes it into account (I seem to remember it displaying DC on one of its screens). Also, when showing voltage it appears to...

Field strengths high enough to harm humans!?!?! What do they think these bikes are? EMC weapons? Aircraft could be brought down by DIY 'E-bombs' - tech - 01 April 2009 - New Scientist US military: Electropulse bombs now from next year • The Register Car manufacturers perhaps? Existing...

I've been using my Wisper about 4 months now, admittedly only commuting a short (4miles) distance. As a London denizen, my bike replaces the Tube rather than the car which sits in it's parking space for weeks on end then drives 400miles for a paddling trip. As Mussels says, it's not free...

That's the one! You can sometimes find the exact same model on Ebay for much cheaper. The best thread on ES is: Endless-sphere.com • View topic - Kill-A-Watt hack job However, the circuit board in the pictures didn't match mine. But the mod is simple: 1) Cut/desolder one leg of...

Yes this is EXACTLY what happened to my fuseholder, dodgy connection caused smell of burning plastic! :rolleyes: My method for measuring current and consumption (well not mine it's actually from a number of posts on Endlesssphere particularly by TylerDurden), is to use a modified plug in...

100 Watt, that's just silly! ;) The other idea I had for your circuit was to common each of the LEDS at to it's neighbour. So instead of 20 independent strings of 3 in series you have 3x20 LEDS in parrallel arranged in a series string of 3x 20 parrallel LEDS. (language is failing me here!)...

Looking good! :D Re: the resistors, you might want to do some experimentation on this as the specs of the HK LEDS I got seem to vary quite a bit :( I found that my LED chain was pulling 40ma (LED rated at 30ma) even though I'd done all the calcs! I kept getting LEDS blow after a time. I've...

Well the underlying technology is not bike specific, but the cases and connectors are. So if you are happy with electronics and can figure out how to physically mount the battery then DIY retrofiting is possible. If you are happier with an off the shelf type system then you need to ensure you...
