I’ve found flickering issues are very commonly associated with ground problems. The retaining ring on the switch pcb, or even the bare metal under the switch pcb, quite commonly causes these kinds of issues. Most likely there is a place in the multiple contacts that has dirt on it, visible or otherwise.

That’s been pretty much my experiences too.
This problem seems to magnify drastically when you start pulling 10 amps or more, which Dale does quite frequently.
When asking for lots of power, connections, wire size and length, spring resistance and battery sag mean everything.

I don’t know if this is appropriate for Mtn’s thread page or not but I was wondering if there was any interest from the group in the SST-20 LED’s (HCRI especially but also the high flux) enough to make it worth Richard’s effort. I foresee buying more of them a good bit myself. Same goes for AlexGT’s inquiry with the 3V XHP-50. Just a little feeler. Peace!

BlueSwordM has a group buy going on here that, in addition to his springs, includes SST-20:

Second Generation Silver Plated High Current Beryllium Copper Springs and 95+CRI SST20!

So, I’m here again guys with the BeCu spring groupbuy interest list. Only this is for the Part 2 GB with upgraded silver plated BeCu C17530 springs, instead of nickel plated springs. Just by doing that, we will be gaining a 5% increase in conductivity alone, which is nice, along with much better contact resistance. So that means even better spring for high current applications. Here are the specs of both the small and large springs: Small spring: Material: Beryllium Copper C17530 38% IACS S…

He’s ordered some, and I lost track of what he is still planning to order, but you can always ask.

The other option is Kaidomain currently offers the SST-20 in multiple color temperatures and decent output bins.

I’m expecting Richard himself to be coming in here soon with some really good news.

Ohhhhh Riiiiichard……?

Wherefore Art Thou, Counselor?

LOL

[BlueSwordM]

I still have 3000k SST-20s left as iamlucky noted.

[Tom_E]

Any hints? LED's, batteries, drivers, lights?

[BlueSwordM]

Yeah, give us some hints

The suspense is killing me… :disappointed:

Please be programmable, linear drivers in various diameters (like Led4Power’s drivers but it more diameters).

I know the website says 20mm & 22mm boost drivers will be available soon. But that’s been on there for a while now.

New Emisar 18 LED light?

@contactcr

New Emisar 18 LED light?

Lol I think you’re onto something

@Skylight

Congratulations!

I have got a question about two of my MTNElectronics drivers: I mounted the 20mm 7135 driver in a cheap zooming light, it worked well for quite a long time but after I screwed it up recently there is only one of seven modes left. I already controlled for a short and unintentional direct drive but found nothing. My 26mm FET+7135 driver works well with an XHP70.2 but a minute after turn-on it starts a slight and continious annoying flickering. How could I resolve that? All suggestions are welcome! :student:

As Dale said the most common cause is a bad connection, usually either the driver retaining ring, the switch retaining ring, or the body threads which when either too loose or too tight cause problems such as forcing the mcpcb pads into contact with the reflector. Several places to look but start with the rings.

@BlueSwordM

Yeah, give us some hints

Ok, so was it something with 18 LED's? Ol news now...

[RAW74]

Well today’s been a bust!No news from the Raspberry Pi foundation, and nothing from Richard. I,m going to bed early then.

[Yourrid]

There is a new Convoy S11 host listed on the site, which I haven’t seen before… which would go nicely with a 22mm boost driver that’s been in the works for a while.

I think it’s going to be the boost driver announcement.

[ToyKeeper]

I don’t know what the news is, but RMM’s last post here suggested he was a bit overwhelmed… was recovering from a serious injury at the time, while also running a business, keeping a day job, and raising a family. Also possibly finishing law school or perhaps setting up a new legal practice or otherwise pursuing a pretty intensive career. Oh, and developing new hardware for BLF. That’s a lot even for the most motivated and energetic of people.

Just a quick update on things: You all have probably noticed that I've been a bit quieter here lately. A few months ago I broke my tibia (big bone in the lower leg), cracked some ribs, and injured my shoulders. A few weeks after that, I fell down on the crutches and broke my wrist. Needless to say, it made working difficult and so even though I could still keep up with orders, I wasn't as fast as usual and couldn't work as long so I was trying to keep to the bare minimum as far as any other …

I did order some goodies from him at the end of Feb and his website had a popup saying he was going to be on break for a little bit, it took about a week before stuff shipped out but for a US shipper with quality products Im willing to wait.
