[MOD] RRT01 (slo-mo progression)

First 3pcs of aluminum pills. No wire holes nor screw threads machined. This will make modification easier to fit different MCPCB styles

A successful weight loss program:

Stock brass pill = 17,08gr
New redesigned 2024 pill = 7,22gr

[Clemence]

Good job! Any idea why they use brass for stock pill when it is heavier, less thermal conductivity, and more expensive than aluminum?

I’m in for three

In for 3!

I’m still interested as well. Looking forward to what TIR angles work with your quadtrix too.

Did you make a special board or are you filing down a bigger one?

UPDATE 190802:

I hate RRT01 driver, it creates almost as much heat as the LED. Tried to lower the max current by changing the sense resistor from 0,05 Ohm to 0,18 Ohm. I wanted to make it safe for a single E21A and get slightly more regulation, which wasn’t the case. Although now the output current is reduced to ” single E21A safe” at 2,55A/4,2V, the current still going up and down depending the the input voltage.

This is weird because the driver doesn’t look like a linear driver but behaves like one. Later Zak told me that this is actually a boost driver. OMD! I completely forgot this light designed for CR123 (3V). Now that explains everything. Any boost driver with input voltage higher than the LED output will behave like a direct drive or to be exact a more like a constant power driver. Only after the battery voltage is lower than the LED then the driver can maintain regulation. Big thanks Zak!
With 3V input voltage the light went into full regulation down to 1,4V.

Tried the driver with all 6V LEDs I have laying around: XHP50, 144AM, GRV3, and 6V quadtrix E21A. Nothing works since the driver can only pump up to 4,8V output from 1,4 - 4,2V input.
So, to make the light and driver works with single Li-Ion a new driver is needed. But making a new driver beats the whole idea of modification, looks like I’m almost creating a new flashlight at this point. Any idea guys?

Lifepo4/RCR123A 3.0V garbage rechargeable?

It would work with a quadtrix, wouldn’t it? A good regulated driver would be preferable, but it’s not what is easily available.

It’s rather disappointing to hear that Jetbeam markets such an appealing light concept with sub-par driver.

Depending what the output from the rotary sensor is, perhaps it is possible to use that sensor as an input for an ATtiny series chip, which could then power the LED’s with 7135 regulators. That doesn’t seem like it should be necessary, though.

Let me just say, that I have known all along that my RRT-01 is not regulated, and I still love it anyway.

I dont think it is necessary to abandon the Clemence-01 simply because of discovering what has been true all along.

the lights drift, within a range that represents no more than one hop on the HDS dial, and generally much less. the HDS dial hops 50% for each of 24 steps through its range.

I prefer the RRT-01, in fact I VASTLY prefer the RRT-01, and that is after becoming fully profficient in HDS speak and HDS programming… Im not just making this stuff up as I go along.

I made a conscious, fully informed decision to embrace the RRT-01, despite its magnetic drift characteristics…

some of you may recall that in the past I greatly resisted accepting the unregulated output, but in my real world use, when the light drifts, if I notice, I just adjust the dial again.

its not as big a deal in actual use as it seems to some of us who are focused on the minutiae and numbers that describe a flashlight feature set.

flashlights are not precision instruments. Not even an HDS runs fully regulated. They hunt up and down all the time within what for most people is a not noticeable range of 2%. Plus they use PWM on low modes, that some people can actually see.

The constant current flicker rate of the RRT-01 is less noticeable, with the naked eye than an HDS.

all that to say, stay the course, do not abandon ship. Trim the Sails, full speed ahead.

if you build it they will come
a Clemence-01 is still a class act, no matter what the reality of the RRT-01 driver entails.

Its a Great UI! Go for It!

this is no real LifePo4 it’s a normal 3.7V with a step down converter, not nearly capable of driving any current above 1A with a reasonable efficiency

I agree 100% with jon
But honestly i just need those alu centerbody sections for easy MCPCB swap with standard size. Only that would be great progress.

I like it when people agree with me, thanks!:slight_smile:

the size of the MCPCB that fits in an RRT-01 is also being discussed here:

you may find it informative

Not sure what you mean by “standard size”
to the best of my understanding the RRT-01 needs an MCPCB of 12mm, but Im not sure… Im not well versed in those details, yet

LOL :laughing:

I meant 16mm boards as standard. As i presume from the pics this should be OK.

I think not a direct fit:

Yeap but i’m thinking of clemence new alu centerbody which has opening of 16mm.

ah, thanks, did not know that… Im just catching up

alternatively, clemence also has this 10mm E21a board:

Clemence wants to install these for quad ultra hi cri mod

RRT01 pill OEM or modified can’t take anything larger than 13mm. There’s just no more space. A single E21A won’t survive more than few seconds. The current is almost 3A. I wanted to make a dedicated 12mm quadtrix E17A for RRT01 but decided not to further make it due to several limiting factors. I am working on it, to make it more universal.

As for the moment, I’ll hold anything about RRT01 modification. I just can’t take the driver as is. In my opinion a new driver is a must for this RRT01. I found a good ready to use IC capable of buck, buck-boost, or boost ideal for this RRT01. We’ll see if I have the potential to make an LED driver.

If there are still enough interest for the aluminum pill we can start an interest list for a GB. So far the estimated price I can give for an aluminum pill (with or without MCPCB mounting holes) is $17/pc. It doesn’t come with the extra O-ring, I made an extra O-ring groove behind the rotary dial to make it completely waterproof.
