I have just under 8 weeks to collect remaining data for this project. If you have had a stroke, please help test a brand new instrument based on morphing faces. D-VAMS or 'Emotiscope' was 3 years in the making. It is not for profit and will be freely available for use on the internet. www.xvams.com

The "within five years" stipulation has been removed. If you have had a stroke, ever, you are eligible to take part. I'm about half way there now, and just need another 20 participants. Thanks for people who already took part. http://www.xvams.com

Yes, sorry to hear it. Any kind of ischaemic attack is bad and life-changing. This research is intended to help people who've had their language badly affected after a stroke, which happens in about a third of cases. I hope you improve, and can get back to being more like your old self.

Hi, just a notice to any stroke survivors or their relatives, here. I'm involved in a study of a mood assessment instrument and need to recruit some stroke survivors for a short (10-15 min) task. I'd appreciate it if you could pass the link on if you know anybody who's recovered or recovering...

Mouser part 283-6.2-RC (Rx04/Rx05 - 6.2Ω) is no longer available unless you buy a ridiculous number, now (1000), so it's been substituted for part 283-10-RC (10Ω) in the order forms (as per Richard's substitution suggestions). If they go back to stocking the 283-6.2-RC in sensible amounts...

Thanks, Marc. I see what you mean now: the Mouser order forms BOM, *not* the Word document BOM. I've fixed this in the Mouser order forms accordingly. Thanks for testing that out and reporting the corrections. It should all be plain sailing now for anyone else using the Mouser forms. :)...

Nice work! Great to hear it all came together so well :). Yes, the first cell-circuit is sometimes a teensy bit off, but I've been running mine with my 24s2p pack for over three years without issues. I saw your build thread: great job! I especially love that crazy custom pack and sheet-metal...

Thanks for the heads-up on the Rx07. I've changed the amount to 24 in the Mouser parts list. U2/U3 *does* require 2, - one for U2 and one for U3 (same chip). Look on the board. http://www.zenid.com/images/GF4.1b_L.jpg As for your query about Rx01, well you know it's 73.2K for LiPO, and 48.7K...

I just knocked something together out of 3 CellLogs for mine: http://zenid10.wordpress.com/2011/09/05/monitoring-pack-cell-voltages/

I've put together shared project forms that can be used to order the parts. Zephyr 4.1b LiFePO4 24s components order form: http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=7b8daff5cc Zephyr 4.1b LiPO 24s components order form...

Ah I see! That's okay then.

So, basically, Richard, the answer to yopappamon's question about daisy-chaining up to 48s is yes, but a minor mod needs to be made to keep the voltage regulator powered from 24s, right? I'm guessing cutting a track somewhere and adding a crosswire... Can the control circuit FETs take it, or...

Are you saying it could theoretically go to 100s? Wow! What's this limit based on? I thought the FETs would get toasted with that much wallop!

The new batch arrived today. Say hello to the Zephyr 4.4b. :) Extreme close up: http://www.zenid.com/images/GF4.1b.jpg Thanks to everyone whose pre-orders made it possible! Here for more info: http://endless-sphere.com/forums/viewtopic.php?f=31&t=55125

Richard says that each board is suitable for "5s to 24s" (as specced in the shop). I take from that that it can handle a minimum of 5s.
