Just for info. I found an online shop which offers the Ankaka battery. I'm not sure if it's in stock and how reliable the site is, but here is the link: http://www.freenergyshop.com/incredi...rtable-battery

Stanley, if the C2 is taking the power from the battery, can my custom USB cable forego the 5 volts power line (1x line of 4)....so only the data channels (3x lines of 4) come out my computer from the USB cable, further isolating any computer noise from the input cable ?

It is the original USB B type socket. See http://www.usb.org/home for the number of pins and connection method of the various USB plugs and sockets.

Just looking at the amazon page for anker batteries. There are a whole bunch of them - http://www.amazon.co.uk/s/ref=nb_sb_...ix=anker%2Caps Is it really necessary to spend as much as £50 to get acceptable/good results?
There was another battery which was mentioned a while back in this thread, with solar panels, but it had multiple outputs, and IIRC some were quite high voltage. The idea of having a battery which could be inadvertently switched to a high voltage to fry the equipment scares me, so if I go this way at all I'll look for a battery which can't deliver more than the max voltage for any of the connected kit. I think that battery was this one - http://www.amazon.co.uk/exec/obidos/...uct_refresh_T1 by Poweradd.

Hi Dave,
This is the battery that I have:
http://www.amazon.co.uk/20000mAh-Mul...keywords=anker
It's true it is £49.99 from Amazon, but note also that the list price they show is £119.99 so quite a reduction. Loads of people are using this battery and is is proven to work.
For your information, very interesting article about the noise from regulators and battery power to see what kind of levels we should expect. Quite old, but I think still adequate: http://www.tnt-audio.com/clinica/reg..._noise4_e.html
I use an LED bulb to stop the problem of my Anker battery cutting off power to the Bushmaster 2 but the grain of wheat bulbs burn out quickly. I was thinking of fitting a resistor instead. I presume a 12v one, say 0.3w would be ok?
Stan-any modifications for the BM2 or did it just get superceded by the Caiman 2?

Two bulbs in series should last a lot longer. I haven't got one of those batteries so I can't paly about with one and determine component values such as the value of a suitable resistor. But I'll play about and see.
As for upgrades to the BMI and II: I am trying to wrap up another project that I have had to put aside a few years ago when my eye sight started to fail. But now that I had two operations to restore things to "normal" I want to get some of these old projects completed before the end of summer. But I am working on a few BM related mods. I even had to buy a BMI back from someone so that I had one to play with!
