Thats the wrong link, New Boost Driver ????

Like I said, if intersted they are for sale. I will be selling these in all the handhelds here as well.

The offer is there for those who want to push their 8x with more current.

yobresal · 11-06-2009, 07:23 PM

I must say these drivers look very attractive. It is a bit odd though for an new driver to the market to make it's first showing above the price of all the other boost drivers. I'll will bet you will sell a boat load of these if you match or undercut Dr.Lava. No offense Dr. I love your drivers.
Nice Work!

robjdixon · 11-06-2009, 07:24 PM

If you have a flexdrive or rkcstr driver hanging around, can you take a comparison photo please?

Rob

wannaburn · 11-06-2009, 07:47 PM

Thanks for the feedback.

@ Yobresal, this is the same type driver in the pen you bought from me some time back. I have put countless hours into the R&D for it to match my personal needs. The price may seem a bit steep, but for all that went into it, and the fact that its the only driver availible that can push the new 8x from 3.6v, over 500mA, I thought the price wasnt too bad.

The price is 25$ shipped for anyone who has had business with me in the past. I seemed to forgot to mention that above.

@ Robjdixon, I will take a pic for reference. The latest Flexdrive is 12mm long x 9mm wide.

I made these boards a little bigger knowing that most will be using them to push some serious current, and the layout was done with heat in mind.

Mine measure 15mm long x 8mm wide.

Next to a rkcstr, I cant say, I am probably the only one on LPF who doesnt own one..
I have always been partial to boost, just to keep the build sizes small.

I will post a pic in a few mins...

robjdixon · 11-06-2009, 07:52 PM

Thanks. The drivers look awesome BTW

yobresal · 11-06-2009, 08:04 PM

Well I will be the first then to buy one of your drivers. PP address me in a PM and I will send it along. Thanks.

Payment received, as well as the desired mA. I will try to get it out tonight before the P/O closes.

Deliver will be under 14days, usually 1 week.

A + / - 20mA swing could kill a diode...no?

Its + / - 2mv <----- and almost no harmonic signals... So that would be a big fat NO..

IgoreT has quoted his driver using the same IC chip as IIRC 30mv of ripple or so... I have got this down to 8mv and could add more protection, but its simply not needed.

Tech_Junkie · 11-06-2009, 09:01 PM

So if I wanted one set to 90ma for use with a PHR, and it pushed it to 110mA, the PHR is not in danger if its a low efficiency diode? Serious question here.

How about a 6X? A 210mA jump from 190mA could easily kill the diode, if not making the life shorter.

wannaburn · 11-06-2009, 09:09 PM

I assumed from this that you cant set it to the exact mA desired. This is what I was talking about.

LOL, missed that, you should have quoted the part you were refering to.

"At higher output currents, the current is adjusted by a fraction of an ohm." So setting it to exactly what you need will come with some tolerance. The most commonly requested preset currents will be my target for now."

When stting this driver with an r set for 190mA+ of current, the resistor has to be set by a fraction of an ohm. If somebody wants a specific mA set and I dont have the resistor, I will set it as close as possible, under the advisement of the buyer.

If you want 190mA I have the 1% tolerance res that will provide 190ma on the button. If somebody wants a strange number and I dont have the exact resistor, I can simply get it close, or just get more resistors...

I have only used these at under 240mA and have limited types of resistors.

I will add more as people ask for various currents.

This does not mean the driver will drift 20mA... The buyer has final decision on the preset current.

Read his post again.
The ripple is measured in mV not mA.

Tech_Junkie · 11-06-2009, 09:32 PM

I read it 3 times. I dont understand were the + / - 20mA applies. Is he saying he cant set to exactly what you want because it has a 40mA swing?

No swing... read the correction..

lasersbee · 11-06-2009, 09:38 PM

I think what wannaburn said in his 1st post (correct me if I misunderstood)
was that he could set the output of the driver within +/- 20mA of what you wanted...

I would think that.. that should be tightened down a bit...
If I wanted a 110mA driver I would not want a 140mA or 90ma
showing up...

Its only an issue at higher currents, setting for a PHR, I have tons of resistors and can get it within a mA or two.

But for people who request 304mA, lol I will most likely not have a correct value resistor on hand to get it bang on.

As I said, I will be focusing on the most common currents used, 80mA, 90mA, 110mA, 190mA 290mA and so on.

*Edit* Okay no more tolerance talk, I will be ordering an assortment of resistors tonight, so its going to be + / - 2mA to any requested mA within the bound of the above specs.

Tabish · 11-07-2009, 06:52 PM

Would these be good enough for driving 12x diodes ???

Asherz · 11-07-2009, 07:14 PM

First I must say the drivers look very nice, the PCB is very stylish

I was reading the other thread where you seemed to have a bit of a disagreement with another member, but I think that was down to who owns what in which schematic.

I will wait for a few tests of your drivers to be done before I purchase any but I do look forward to owning one as they look very nice, and seem to work well from what I have read.

Although I must ask, if you have to individually change the resistor on each driver, and you get bogged down with orders will it not be potentially very difficult to keep up? As with most other drivers they have a pot so they get built and shipped. I don't know much about electronics beyond a certain level, so I must ask is it not possible for you to potentially replace the resistors with a potentiometer? This would also allow us to re-use a driver with another diode if an old one dies. (Please excuse my lack of knowledge if this isn't possible

)

wannaburn · 11-07-2009, 07:55 PM

I’m working on a pot for this actually right now. I have used these in hundreds of builds, and for the most part with lower current diodes, no higher than 6x and under 240mA.

The challenge with this driver and setting the current is in the range from 193mA and up. When setting the current for 193ma, it’s as simple as a 1ohm resistor. Above 193ma the current has to be set with resistors at 1/10th of an ohm etc.

Ex. To get 393mA a .49R is used, and for 402ma a .48R is used.

The problem with using a pot is the current has to pass through the resistor as is, so a combination of pot and resistor has to be used to take the load off the pot. This is something that would make it easier, but not necessarily better. The fixed resistor is much more reliable over long term. But is still doable.

I’m ordering more resistors to try and broaden the range of selectable currents.

@Tabish

For the 12x, I will have to see what the vf and current requirements turn out to be. As of now it can deliver what the 8x’s are running at. So for the 12x is anybody’s guess.

It will meet the requirements of voltage with no problems up to 25v, but the current may present an issue over 300-350mA if the vf of a 12x exceeds 7-8v. This would be a heat issue, but will be testing some work a rounds for that soon.
