I used to feel this way about Microsoft. Long story, but the short version is they were The Enemy, and I hated them so much I refused to even spell their name correctly. But over time I eventually figured out that they are not, in fact, Hitler. The people who work there are not stupid or evil. And the problems they worsened weren’t really proof of their evilness, but rather symptoms of a broken system in which we all operate. It was mostly just a bunch of people trying to do their best, guided in the wrong direction by messed-up incentives in their environment.

So… I got better. But at the time, I said some things which were, in retrospect, pretty embarrassing.

In any case, sometimes bouncing ideas off someone is a helpful part of a thinking process. That’s all the cardboard cutout thing was about.

Thats a very humane POV.

Having worked on a project there in the Longhorn era, I will say, I came into contact with a lot of people who thought the sun shined out their asses. They mistook being in the right place at the right time for an act of intrinsic virtue, of their superior choices. It ended up hurting the company, because it blinded them to the fact that perhaps the way they’d always done things wasn’t always the reason they’d succeeded, but rather, that they’d succeeded despite the way they were doing things. That’d be more satisfying if most of them had suffered serious material setbacks for their arrogance, but they’d already cashed out enough to be set for life on their big-ass boats, etc.

When I started on the project there was a Dianetics reading room a short distance from the edge of the MS campus. A little before I wrapped things up ~2.5y later, the scientologists had moved on to a new feeding ground. In their place there was a different breed of predator, a pawn shop.

I wasn’t too keen on MS or Intel’s duopoly back in the day, but I was also very conscious of the fact that they provided the economic engine that drove computing from niche to mass market. Without them, at that time and place, it’s a lot less likely that some teenager in Finland would have had a 32-bit computer with an MMU to write a *NIX kernel. Or, if he had, that contributing to the project would have found as many willing and skilled volunteers.

Sure, things would have continued moving forward, and that capability would have eventually become affordable, but it probably would have been somewhat later. A lot of history is like that. But enough about all that…

This non-political signature is not non-political.

Hi Richard! Sent you a PM with a question about one of your drivers I am considering in purchasing. Thanks!

Richard,

I am in the process of ordering one of your CUXM/CUXP P60 drop ins. Would it be possible to have you upgrade the 219C to the 90+ CRI version? I have the older version with the 219B LED in one of my other lights and love it. It is the reason I now have to consider strongly whether or not to purchase any light/drop-in that is not high CRI. I would be willing to pay a few dollars extra for the privilege.

Thanks,
Tim

Richard has announced his new boost drivers on his website home page. Looking forward to trying one of these! My first project will be an xhp 70.2 in a short 18350 convoy s2+ host…

That’s great news! But I’m just wondering why is it so difficult to make aftermarket boost drivers. Thrunite has single cell XHP70.2 and XHP35 drivers. Acebeam has single cell quad XHP35. Even Haikelite has a driver that can run XHP35 with single cell.

One of the issues is the components and pcb being able to handle the high current. You could have 15A to 20A running through the board. Components burn up, pcb traces get fried, etc… FET’s run their high current through the driver a different way which avoids these issues. You also then need to adapt a firmware to work with it. Sometimes you have to change the driver layout to adapt to the firmware.

I’ve also heard that Lexel got NarsilM working on his boost drivers.

Oh, I just remembered the most important reason. Those companies have research departments. They can pay people a salary to sit there all day to design and test prototypes and have big budgets to buy all the parts and equipment needed.

The independent guys like Richard and Lexel are just working on these things in their spare time with zero pay while trying to operate a business. So it takes them much longer. They are getting there, though. Thumbs Up

He says it will be released in August. For right now it’s just an announcement that he’s going to be selling them.

Here you go.

Yeah. I’d be happy to send him money just so he can get paid in advance to make the drivers.

Pre-ordering hardware is the only kind of pre-ordering I am willing, and accepting to do.

I saw the answer from the other thread.

Basically it is an unfair comparison. The highest power production single cell XHP35 boost driver I have heard of to date is around 1.5A.

The drivers we are working on are designed to deliver 2-3x that power

A 1.5A boost driver is fairly simple. That is only about 6A input. We are doing closer to 20A input.

I think Richards boost driver can do some 5A to 6V emitters and around 2A to the 12V XHP35. Should prove interesting and especially so if/when he adapts them to a ramping firmware. Big Smile

Can’t see much need for 2-3 x the power if it blows an emiteer that peaks output around 2.5A

I actually wonder why he didn’t mention 12V LEDs in his statement. Surely it’s just omitted and not just 6V? Guess we will have to wait and see!

Yes, 6V and 12v.

Lexels are about 6A@6v and 3A@12v. I believe Richards will be about the same. They may be adjusted down a bit to make them more reliable.

I know on Lexels you can adjust the output with a resistor swap if you want to reduce the max output. I assume Richards will be the same.

For instance, with a xhp70.2 you might want 6A@6v, but with a 50.2, that’s too much current. So you would swap the resistor to give you maybe 4.5 to 5 amp at most.

We all just have to be patient.

These boost drivers will be a hit, assuming they work well. These will offer multi-emitter performance without the work of making a spacer and finding suitable reflectors. I plan to put a sliced XHP70.2 or XHP50.2 in an emisar D1S.

This makes me think of the Sofirn C8F. It’s about the same size and I think the output level and hotspot size will be about the same. Have you considered that light?

I agree, I think the C8F with dedomed XPLs would have similar performance. I did buy the host but have not built it yet since I’m still deciding on the emitters. I have a few lights in this size and output range so I’m trying to think of how to make it a bit different.

But I think the D1S is a special host. It’s very light and compact especially for its reflector size. For a short time I had my 3×3 array of XD16s in the light and and I liked it, but the XD16 array is not reliable yet. So a sliced XHPx0.2 is the next best thing.

Question for you guys:

I currently have a C8 with a XHP50.2 and a RMM FET with 2 18350’s in it. What do you suppose one of these new boost drivers would do to the output of a XHP50.2 when changing over from 18350’s to a single, high drain 18650 (30Q/VCT5) and one of these drivers?

(Obviously these aren’t out yet, so no one knows exact specs. It’s all conjecture at this point)

I did a similar C8 mod a couple months ago. I ordered the parts from Mtn of course, and I asked Richard if I should wait for his boost driver instead (he teased these on his Instagram page last year). He said the 2×18350 with fet would definitely be brighter, since the boost driver will only put out about 3.5 amps at 6 volts, which will be 8-10 amps pulled from the 18650 as the voltage sags.

But as you said, let’s wait and see. At the very least, you’ll get much longer run times, right?

I would guess a lot more runtime and a little bit less peak lumens at turn on if you are comparing turbo.
