Very cool!

How much money will the components add to the cost of the unit? And how much has it run you to get this improvement into the patent system?

Neat idea.

The only thing I can think of that perhaps you have'nt (saw no mention of it in your post) would be the need for either an off switch of some sort or a cover for the panels to prevent charging. If in the field your rechargable batteries were to give up the ghost for whatever reason and alkaline batteries needed to be pressed into service, the auto recharging feature may cause them to leak, damaging the sight.

Other than that one small concern, I would be interested in such a item. Better to have it and not need it, than need it and not have it.

Tag.  Cool idea.  It would not work for me though since mine spends the majority of it's time inside and rechargeables are always dead when you go to use them after a few weeks of storage.

And this is what makes the idea of a solar charger so silly. The fact that you are relying on an optic to begin with that places such high demands on a batteries.

Aimpoint has it right. Add new battery before your one year deployment then turn it on and forget about it.

Did you have a patent issued? If not, you may have just jeopardized that ever happening. Once something becomes know to the public, it changes the rules. My company has hundreds of thousands of patents, and we are very careful with who we show prototypes to. Europe has the most liberal policies, meaning, if I show something to someone over there, and they decide they want to patent the idea, they can because the product became "public domain" once I revealed the unprotected product to them. I would consult with your attorney about showing off your work before the paperwork is finalized. I wouldn't want your idea to get stolen.

IMO this is a great idea and something like this was overdue.

I'd be interested in having it done.

good luck on your patent app.

Without going into too much detail, could this system be made into a stand-alone kit for home installation?

You could sell the system as a kit and also offer installation depending on the requirements of the customer.

A solar powered optic would certainly swing me toward the Eotech over the competition.

Man, just when we think you have thought of everything, you think of something else. You are turning into the Edison of modern firearms.


And I know you will show this baby to us at SHOT, right?

Nifty,

I wondered why the company didn't set up the eotech so you had different battery modules.  Ie have the basic sight portion, and be able to plug in the AA, the N, or CR123 battery sections in.

TWL, if you don't mind my asking(no problem if you don't want to say),
Does this just effect the battery compartment, or is the tied into the eotech electronics?

Well re-read the post and I see thats it is tied into the battery compartment.

Quoted:
I used NiMh batteries, to eliminate the charge "memory" that happens with NiCd batteries, and NiMh has no "memory" so it doesn't matter if you are charging up to full or anywhere in between. It doesn't affect the capacity of the battery to function well.

I respectfully disagree with this statement NiMh batteries Do have memory, but not as bad as NiCd. Lithium batteries Do not have memory.

ETA: Nice work none the less!

I think that once you receive your patent, that this would be worth showing to the folks at eotech.

Can you imagine a generation or two down the road?  Holy moses.

I guess there's no plans to make a solar charger for night vision and thermal sights?

Whatever happened to the idea of a centralized energy source to power all the devices that need electric power, opics, lasers, NV/thermal devices, etc. that heretofore use their own batteries and have their own battery housing?  I think the solar recharging can be of huge service if the centralized power pack ever comes to light.  Imagine if the EOTech, lasers, NV/thermal devices doing without their bulky battery housing, they can be made much smaller, and we wouldn't have to carry all kinds of batteries with us

+1,000 for Ingenuity! I do have a question. Will the sight still be usable with regular  non regargable batteries?  What if the solar panels gets damaged?

Are there any solor panels that don't have the white "box" outlines on them?

Some people may not like the grid pattern this puts on the guard.

What about the "memory effect" seen in other recharging cells.  I understand this will be  unlikely, but I think people may want to hear it from you.

That really neat!

How about making solar rail panels?  You use one rail panel per device that needs to be charged.

You missed the point. The research should be invested in making the batteries last longer, not developing devices to try to keep them charged.

The battery in an Aimpoint M3 will last longer in the scope on the lowest NV setting than if it was out of the scope on the shelf.

I never knew a Aimpoint set on the lowest setting, discharges less energy then when the battery is just sitting on the shelf...wow. So the batteries design forces it to use energy when its not being used, but when its used it discharges less.

Back to the point.  An Aimpoint is a very simple device which uses little energy.

an EOtech is a HOLOSIGHT which consumes more power, hence it will need batteries more often with current technology. The OP has come up with an INOVATIVE way to overcome the problem ON HIS LIMITED BUDGET...he isnt EVERREADY, he's a guy just like you and I.  I'm sure the guys at EOtech are looking into ways to drop the power consumption as well.  Alot of the problem is ppl forget to turn them off, or hit the on switch and dont realize it.

Its apples and oranges.  There was a post here about a guy's wife who left the car running all night...now my 68 Mustang even on a full tank would run dry in 10 hours...does that mean I need to switch to a different car?

Tossing some BS around like your post, was uncalled for.

Inovation is great... but I don't get it. Why would you want a sight that NEEDS this??
What happens when it gets dropped on the panel or Kachinks off of something with some force.

and if it's a range Only Idea.. then just bring spare batteries...

Good luck with your idea...

Your a freaking thinker and good luck on the sales side.

Seals, Memory,possible rev. discharge, overcharge, solar cell delamination. wiring connections.

Thats all I could think of for now, it seems youve covered them all already.
Link Posted: 10/21/2007 9:26:23 PM EDT
Great idea, I tried doing something simular to this a couple of years ago.  I used a mini usb attachment (much like you would use on a cell phone).  Premise was you could attach it to a power source (wall plug) or solar panel (portable system).  I still have it around here somewhere, but I lost interest in it.  Maybe, I'll get it going again, and we can compare notes?
Link Posted: 10/21/2007 11:03:46 PM EDT
NiMH have a HORRID self discharge rate once fairly well used.  Id look to package your invention with some form of new hybrid stlye rechargables like Eneloops or Hybrios so when users pull out the EOtech out of the safe it wont be dead.  Your EOtech would have still been working had those been installed at the patent attys office.

Does the Zeiss's Z-Point not constitute prior art?

Last time I spoke with a patent attorney he explained that the average patent litigation trial was $62,000.  That's just to get to the point of a judge telling the other guy to knock it off.

The attorney told me he'd love to take my money but it would be better spent on production.

Best advice I've ever followed.

Have you looked into the new long-shelf life NiMh batteries? I have a set which is supposed to retain 80% of charge after 12 months.

Haven't fully tested that but I keep them in my camera which gets used once or month or so it's always had charge everytime I pick it up. (had to recharge after 6 months because I left it switched on)
Link Posted: 10/21/2007 11:41:11 PM EDT
What are you using to prevent over-charge?  Some type of regulator built into the existing cuircut maybe.

and what about "reverse" flow into the panel? that would then discharge you batteries...

Interesting concept . It appears to be simple and viable despite
the concerns of the detractors . Keep up the good work
