The E-drive (V3) + PDF

Re: The Elasti-drive Intro (V1 and V2)

Laser Drive?

You guys have got something good going here. I'm actually excited.

You rock and I can only hope that we don't end up taking it, or you guys for granted. This sounds like an ideal-driver so far - its even got better specs than the flexdrive iirc!

Re: The Elasti-drive Intro (V1 and V2)

How about LP (laser pointer ) Drive
Or something along the lines of that but simple

Names aside, I don't care what you call it but let me know when I can buy 3 or 4 of them!

what do you have against your username?

EDIT: I like the DuckDrive

I'd rather not say but Elasti-Drive is Still a TEASER for the good ole Flexs-- being quite a bit upgraded and capable of higher currents i would simply say to be the best ones on the market cant wait to grab a couple of them as soon as they're out..

Also i think "E-Drive" OR "eDrive" would be simpler and keep the very essence of the concept still attached to it!!

Re: The Elasti-drive Intro (V1 and V2)

How about the SexDrive

Re: The Elasti-drive Intro (V1 and V2)

how about the pasta driver... ummmm pasta

Elasti-drive sounds too much as if you are trying to follow after Dr.Lava and his flexdrive. I think this is a unique driver and it should have a unique name that will make it stand out. Quack-drive although may be cartoony says that its creator is not without a sense of humor. That will draw people to you!

And I get credit for suggesting it originally muahahahaha

P.S. elasti-drive also sounds as if its made of rubber... a bit weird... but the ultimate decision is yours of-course

I think the original idea behind the name was to make people think of the Flex Drive but once you start reading the specs, it is actually better than the flex.

And...I haven't seen any mention of the tsteele-drive or T-drive.

I just want to make a few comments on the driver after actually using it...

That is great, what did you use it in and what current did you get?

I love the fact that I can use many different battery types. It's nice to have options for the power source, which is always an important consideration when assembling a high power portable laser.

That was something that Jared was excited about with the IC that we chose. It is an expensive and somewhat difficult-to-use IC, but you get a LOT of really nice features. Lots of inputs, over voltage, under voltage, thermal protection and so much more. The VERY "flexible" input options mean you should be able to run this driver off of anything short of an AAA battery. Well, pretty much...

The output seems stable and the driver does not produce much heat which is something I appreciate very much.

So far it looks very, very good on the scope. We will do some really hardcore testing before we start selling the final products. We kept putting bigger and bigger caps on the output to lower ripple and startup spike and then we discovered a totally different way to approach the problem and all of a sudden a ton of problems vanished. We had been barking up the wrong tree - :undecided:tackling the wrong area of the circuit.

That is why the final versions will be smaller.

As for heat, the heat DOES start to come into play at higher currents and even though it is very efficient, it will need to be heat-sinked at some point. ~800mA?

But there are a couple suggestions that I think would make the driver even better than it already is...

Click to expand...

We are all ears! That is what we want our early adopters to do... test and make suggestions. Hopefully we have tested it well enough not to be sending you lemons, but we are very interested in developing a driver that does what you all want it to do! Of course there are the laws of physics to contend with and there is cost. We can make this thing ridiculously small and powerful but those things cost more $ and we are determined to keep it affordable.

First, I'd really like to see the output pads centered. I really like to hook up the driver directly to the diode since I mostly build compact lasers (usually pens). Unless the diode has long pins it will be difficult to make a direct connection. Using wires can get messy and takes up a lot of space - something which there is not much of in a little pen host.

Love this idea, we have already started building them smaller and the boards are getting the output pads so they can be used in very tight quarters.

Making the driver a tiny bit smaller would also be great. I had to file down a little off the sides to get it to fit just right.

Click to expand...

Of course by now I've mentioned it quite a few times, but we have indeed done this.

Besides the size/shape of the driver and positioning of the components and output pads, I think this is a great driver and I think that future versions will be even better.

Thanks to people like yourself I think it will continue to improve.

Thanks a lot to all who worked on it. I'll look forward to seeing what you have to offer in the future.

Re: The Elasti-drive Intro (V1 and V2)

I got it !!!!! LeSteel-Drive perfect name !!!!!!!!!

Re: The Elasti-drive Intro (V1 and V2)

My 240ma driver is being put to use in a leadlight build. Extremely stable when running a single mode osram even when boosting from 2xaaa batteries. Before assembly, I had this driver hooked up to my 3A test load for 5min and it was barely warm! Diode input pins not being centered mAde the build a pretty tight fit but I am impressed with this driver so far! I will definitely buy more when they're available
Thanks for the awesome driver tsteele and le quack!

My apologies, I got carried away how about QT-drive
or varidrive - variable-driver

Thanks, we are testing the adjustable pot versions right now, I still feel like they need a good solid round of testing before we drop them. But the fixed versions are pretty well vetted and the variables are basically based on them.

My biggest concern is those pots. I haven't figured out how much I trust them and what they could cause as far as problems go... Probably nothing. But I really want to put them through the ringer.

Lol, you are too funny gillza. What is your avatar? It looks like a shot from some of the Walt Disney anime movies my kids watch!

Re: The Elasti-drive Intro (V1 and V2)

A note to make; For all drivers without center pads, you can actually cheat a little, and hook it up like this;



And it will still work properly. Just for those who would like to know

I detect sarcasm? Maybe not. Well that is not some Walt Disney stuff that is from one of the greatest ANIME ever made: and her name is Haruko Haruhara

So how is the work going on the driver?

Le Quack, thank you for your PM!

Re: The Elasti-drive Intro (V1 and V2)

I didnt sense any sarcasm in that whatsoever. Just some people dont pay attention to these kinds of things

I hope you kids enjoy the world that you have created. For I will be long gone.

Re: The Elasti-drive Intro (V1 and V2)

I didnt mean to be harsh! I swear! Sorry if I did, I really didnt mean to

I edited my post. Sorry if I offended some people here, I love you guys
