[EVDL] IR cameras - energy tool
I borrowed an IR camera to look around the house. Its amazing waht these $400 cameras can see. In my old house, I can see vertical columns in the walls where the blown in insulation never reached. I then looked indoors at the 2nd floor ceilings and could see some obvious cold spots. But the weirdest one was when I was in the basement looking around at the overhead wiring and circuits. You could see which wires were carrying current, they were bright white against the cold blue background but there was one nearly white hot spot on the floor above one area. I knew there was nothing there so I was worried about an unknown imbedded wire building up heat. It was a large spot about a foot in diameter. I went upstairs and found a cat. Amazing. The cat was on top of a 1/2 thick wool braided rug, on top of 3/8 of ceramic tile, on top of 3/4 plywood flooring, on top or 3/4 of tongue and groove decking. Almost 2.5 of solid material and yet he was as visible as if he was a light bulb! SO that's where all that cat food goes. Wasted heat. I also found the camera useful in troubleshooting electric circuits even in our tiny 4 cubesat. I could see where a short circuit was on a solar panel., etc Anyway, I'll probably buy one for retirement when I can no longer borrow this one. For those who haven't seen one, the image is live just like a TV camera. But the trick for really getting a good idea of energy loss is to point a scene and then lock the IR level. This lets you see everything relative to that fixed temperature. If you do not lock the levels, it re-adjusts every 2 seconds and so you can see everything in the one scene relative to itself, but not relative to any other scene, or fixed temperature. P.S. It will be ideal when spring comes and I start working on my EV conversion again. You can see temperature variations in wires that you could never sense with your fingers...

[EVDL] List business: addressing posts
When you post here, if you want your post to show up without excessive delay, please address it this way : 1. Always put ev@lists.evdl.org in the TO field of your email message. 2. Never put anything else in the TO field. 3. Never put anything else in the CC field. 4. Put anything you want in the BCC field. We have had a few folks who didn't do that recently. They tried to send a post to multiple discussion lists. Or for some reason, they addressed a post to several EVDL members individually in addition to sending it to the entire list, which is (or should be) obviously unnecessary. The reason doing otherwise causes problems is that it causes the listserver to flag your message as possible spam. It thus holds your message until I can check and approve it. This will cause your message to be delayed, usually for many hours, often overnight. I know this is a little inconvenient, but it's part of the price we pay to keep this list close to 100% spam-free.

Re: [EVDL] IR cameras - energy tool
We have a FLIR-ONE IPhone5 case. $225 on eBay. Well worth it. Nifty pictures and nifty apps. Eva already used it in a report. Bent some big aluminum conductors and measured the temperature change cause by bending. More than just a nifty gadget, it is a real IR camera. Maybe I should take an IR selfie duckface with a grumpy cat, just to do the expected with a cellphone camera. :-) Bill D.

Re: [EVDL] Need battery pack or sell car.
Hi Lawrence and All, I'm in the same boat but came up with a solution of buying 50% of the pack I wanted for now. It's 5kwhr, 120vdc tough I'll double it up at 60vdc, 90amphr for mine of Volt batteries I got for $1k is far better buy than new Chinese cells, even used ones. Leaf I would have preferred are even easier to deal with if you get that option. I asked on the list and someone with extras contacted me. There are a lot of Volt, Leaf, hybrid, totaled EV's now they are showing up . And the Volt. Leaf is quality enough you don't need the expensive BMS . Instead starting with them balanced either high or low and use a Lightobject 404 amphr meter monitor the pack and cut the charger off. Then some Lee Hart Batt bridge to monitor the cells, connections to warn before something goes bad, gets out of balance, etc. Thus reasonable pack safety for under $100 with massive data. 600lbs of lead is about 5kwhr available so 6kwhr of lithium should give you more range from 400lbs lighter too. So many old, maybe dead EV's, conversions could be great low cost EV's just by converting to lithium.

Re: [EVDL] Need battery pack or sell car.
Lawrence, This fellow, Jehu Garcia in SoCal, bought an enormous number of laptop cells on eBay and put them together in a pack for his VW bus: https://www.youtube.com/watch?v=U4hhMQh3SzM There are videos chronicling all the gory details.

There is a fair bit of electric motor whine and, despite the light weight, the suspension can crash a bit over larger bumps. Sounds like an updated, more civilized version of the old Citicar. The original C-car was almost exactly the same size (2437mm long by 1397mm wide). Although the Twizy is much curvier than the C-car, if you squint at them just right, you can see some overall similarities in shape (tall, short, narrow). The C-car had 35-40 miles of range, and with luck could hit 40mph on a good day with a tailwind. Raising the voltage from the 48v to 72v would push that close to 50mph. At that speed you were taking your life in your hands, IMO. The brakes were barely adequate for 35mph. It had side curtains instead of windows. The early ones had no standard heater, though a propane-fired heater was an option (it was unvented, so it fogged up all the windows when used). The later cars' heater, which tried to harvest waste motor heat, was mostly useless. With solid axles front and rear, it banged and lurched over the smallest bumps, probably much worse than the Twizy does. Finally, the C-car too had ample motor and gear whine. Consumer Reports said One might expect an electric car to be quiet. The Citicar is quiet only when stopped.

Contact the Hybrid Auto Center.com web site. When the page comes up, click Contact Us. They have a Plug in Conversion and EV Parts Shop. You can purchase a four cell module completely assemble that has two 4.2 V Lithuim 33 ah in series and then the two series cells are in parallel for 8.4 volts at 66 ah each. The four cells are assemble in a aluminum case that can be bolted together with threaded rod to form a battery for any voltage you want. The cell terminals are copper and you can connected the modules in series and or parallel to get any ah an voltage you want with copper bus bars connecting copper cell terminals together. You can parallel the modules in parallel to get the ah you need and in series for the voltage you need.

[EVDL] FW: IR cameras - energy tool
Oops, replys to list go direct to Rod (only), hmm. OK, I try again: From: hoegb...@hotmail.com To: rodho...@ameritech.net Subject: RE: [EVDL] IR cameras - energy tool Date: Mon, 26 Jan 2015 01:02:16 +0100 There is at least 3 or more make/models out there in the cheap range, Seek Thermal: this was $200 usd a short while a go, (but now it seems a bit higher priced) and there is a very new XR model now: http://obtain.thermal.com/category-s/1818.htm I can just guess that they did run in to ramp-up problem at that low prices before, now at 300 they should do good profit :-) FLIR: A iphone back-cover, that also have a built in battery. Compared to the Seek it has a crappy resulution (80*60pixl) , that is if we only speak of LWIR-pixels.., but they do a very good overlay together with an extra normal vga camera, that software then put together, give us the edges on top of the blobby thermal image/movies, so the result is enhanced a lot, really nice actually! Also less of visible noise than the SeekThermal. And might have a more uniform measurement over the full screen, (Some say Seek did have some problem with that, maybe the shutter-calibration..something.. As it was like several degrees difference from top of the image compared to lower part of the sensor/image. Strange error.. ) But the thermal range of FLIR One seems very limited! only 0-100 degrees, I dont know if it is just a software problem to fix that later for a more usefull EV-range for us. Also it is limited to just a very few of i-tings, may be iphone 5 only, I dont know if it is hackable (angle-grinder.. :-) for ipads and so on.. Also it is a bit more expensive than SeekTermal. (For RaspberryPi-guys the module can be bought also, for more info google: lepton +LWIR http://www.flir.com/cores/content/?id=66257 That is the Module-page for lepton, (FLIR of course have a lot more modules for OEM:s and also have ready made products, I like the FLIR E8 camera, and stuff like that class and up are *a lot* more expensive. Lepton on the web (module only), is now about 200 usd . ( http://www.pureengineering.com/projects/lepton ) But if you have an iphone 5 and think you will have that phone for X more years it might be a good idea to buy that complete FlirOne-product that is ready and the VGA-overlay that works good, but I would choose the SeekThermal to be compatible with Android stuff in the longer run. And to get the more useful winter outdoor temp-range. But is seems like it is harder to see the smaller diffs in temperatures with the SeekThermal compared to FlirOne, I guess that might be fixed by a software update later, or.. the noise in SeekThermal might be to bad for a more narrow range) here is a Comparison between SeekThermal FlirOne: https://www.youtube.com/watch?v=8Cr8oZck5m8 Here he also shows an add on lens (for a laser cutter) that seems to work very good as a macro lens here, useful for PCB-thermal images (6m30s) And there is also Therm-app: this is the next more expensive in the mobi-LWIR-camera segment, 384 x 288 pixels Give nice result, but 1600 usd... Therm-app have a *much* better IR-resolution than FlirOne, and it also looks(to me) a lot better than SeekThermal.

[EVDL] 10 yr old hybrid transaxles info needed.
Hi All, That right of passage cars, SUV's go thought has come to the first hybrids as after 10 yrs old in parts yards they go dirt cheap. But not having paid attention to these, not sure which is what. What I'm looking for is through the road hybrids using a separate E transaxle in the rear. Anyone know of these and which make, yr to look for? IIRC Lexus, etc SUV hybrids maybe had them. Any other easy to use EV motor that isn't buried in a transmission? There are likely to be a lot of these in transmission or out that can be used as wind, river and tidal generators besides EV's. Especially with a 8-1 heavy duty long lasting gear increase.

[EVDL] Best Hybrid lithium packs.
Hi All, As Leaf, Volts are getting a lot of action, their prices totaled have went up. For another source I'm looking for which of the lithium hybrid battery packs are the biggest, most easy to use or cells that can be used in EV's. Also which if the other EV's packs are good like Think, Spark, etc that might come available that would be a good buy? Thanks, Jerry Dycus -- next part -- An HTML attachment was scrubbed...
