New Boost Driver in Dev

Re: New Boost Driver in Dev *Asking for investors*

I can't wait to see this! I hope it works out. I don't know if anyone has asked, but will this get hot enough at full load to need heat sinking, and if it does, are the parts that need it all nicely on one side?

That is pretty much a industry standard. We are working with good quality parts with decent efficiencies. This will defiantly produce heat, but simple heat sinking will dissipate the heat. I will ask the engineer for heat dissipation estimations for you...

What is this driver for driving specifically again.

... For Driving Laser Diodes I would assume......

Yeah, seems like it is coming along nicely! Can't wait!

 

[bobhaha]

NEW UPDATE... We have finished all lab work now... it will start board work tomorrow and hopefully by the end of the week we will have a working prototype!

I must have been wasted when I typed that.. because that is just a ridiculous question.

Yay! Drivers! I can't wait to see a video or .. at least pictures of it. lol

 

[azzman372]

Yay progress! Thanks for the update!

This is taking forever! I would assume in the world of electrical engineering that this isn't that big of a feat to accomplish. Especially for a company that does this kind of thing for a business?
it took them a month just to design the driver?
I'm a very impatient person, so anything more than 3-4 days for any 1 process drives me nuts.

It will be exciting to see a boost drive available though!
Will we at least get a preview with 3d rendering?

Hey Mohrenberg,

The engineer has other projects that need to be looked after at the same time... giving him only 1 day every week or so to get to work on my project. Not to mention the other projects are multi-million dollar projects where as, mine is just a job he is doing for me on the side, as a friend.

I am excited too! Once prototyping is done, board layout will commence and I will defiantly get a 3D render out for everyone. Plus photos and hopefully videos of it working.

I can't wait!

Even if they were to cost 30+ dollars they will still be much cheaper and more practical than running two Flexdrives!

The problem is not that it is a "big feat" in the world of Electronic
Engineering...
It has more to do with the fact that a company will not drop the
work/projects it may be working on just to accommodate this
project.
It's more like take a number and we'll get you you when it's
your turn.

I've worked on small projects that customers needed to wait
4-6 months because of the work load.
Design.. building prototypes and testing and tuning the design
also takes an undetermined amount of time before a final product
is ready.
That is a norm in our Electronics R&D field.

A months is quite fast to get a working prototype...IMO

I have gotten to test quite a few experimental boost drivers that the community has been working on. Some better than others but all have had issues staying in regulation as the input voltage changes.

When the prototype is done I would love to see is how it stays in regulation from 3.6V-4.2V. Here is how the Flex does. Do you think this is a test he would be willing to do and send you a video?

Here is how most of the prototypes I have tested did. In a single cell portable laser this is a huge swing in output during the battery cycle.

Heh. the flashlight boost drivers i've been using from DX lately and modifying regulate better than that second video. lol

 

[Wolfman29]

Care to share?

Heh. the flashlight boost drivers i've been using from DX lately and modifying regulate better than that second video. lol

And hence.... the problems in designing a new "better"
Driver...

Only testing of this new drive will we know what it can really
do....
