New Convoy C8 – Clearly better

Thank you so much for taking the time to explain this!
To answer your question, yes it makes a lot of sense now. It is the first time I have really even halfway understood it. :slight_smile:
Thank you again. :slight_smile:
(You too Tom E…. :wink: …)

BIS-CON or BISCON

FWIW, some explanation about the choice of mode groups.

There wasn’t room for many independent config options like in bistro, but I could at least fit something similar in the form of mode groups. It allows a total of 24 different configurations, compared to 145 (or 129) in bistro.

The first nine are basically three groups in forward and reverse, with optional blinkies.

1. 0.1, 1, 10, 35, 100%, strobe, biking, battery-check (default)
2. 0.1, 1, 10, 35, 100%
3. 100, 35, 10, 1, 0.1%

^ General purpose group. Note that you do not have to cycle through the blinkies if you have memory turned off. (The groups could only be up to 8 modes each, so SOS was left out. It’s rarely used.)

4. 1, 20, 100%, strobe, biking, battery-check, SOS
5. 1, 20, 100%
6. 100, 20, 1%

^ For people who prefer 3 modes, which is pretty common.

7. 0.1, 1, 10, 50, strobe, biking, battery-check, SOS
8. 0.1, 1, 10, 50
9. 50, 10, 1, 0.1

^ Half-power mode groups, so that 8x7135 drivers can work as if they were 4x7135 with no modification. Was specifically requested. Doubles the runtime, eliminates heat issues, and doesn’t actually look much dimmer. Also works as sort of a muggle mode.

10. 1, 10, 35, 100

^ Because it’s nice to have a moonless version of group 2, especially on a thrower. And because a full-power 4-level group was missing.

11. 100, 20, strobe

^ This arrangement was independently requested by several people, especially for police work and traffic routing.

12. 100% only

^ Sometimes people want a single-mode light, and there were two bytes left over, just enough to add this. The ROM is now exactly 1024 bytes.

Some of bistro’s features weren’t possible (like medium-press for reversing) or took too much room to fit (like “soft start” ramping up each mode), but I put in as much as I could. Hopefully it’ll cover most people’s preferences.

TK understands the science of light a whole bunch better than I. I know radiation is the inverse square rule - double the distance, 1/4 the exposure, etc. Golden 3 rules for radiation are time/distance/shielding, and it travels in straight lines. Light is similar.

Works the same for photography purposes, takes 4 times the light output to cover twice the distance. I have flash units that will fire 191’, or, effectively, across a football field from the sidelines. This takes a massive burst of power and will heat up the AA NiMH cells poste haste! For perspective, most point and shoot camera’s have a built in flash that will fire about 16’, few have a flash that will fire 20’.

When you get hot rod lights up into the thousands, the eye really has trouble telling the difference between hundreds of lumens. Very deceptive, this hobby of ours.

She blinded me with SCIENCE!

… and a flashlight.

I think it was mostly the flashlight.

Thanks a lot! :person_facepalming:

Now I have a nearly uncontrollable urge to rent Weird Science and watch it several times.

Hey, that one’s worth studying for sure! Thanks for the visual TK. :wink:

Dale, don’t hate Kelley LeBrock because she’s beautiful. (from an advert’ of the period)

Don’t hate me because I’m beautiful

I never saw the movie, but she was memorable anyway (I just put it into my Netflix queue, it should be fun). She was at least as memorable as the old Noxzema “Take it off, take it all off” girl from my early teens .

Take it off, take it all off.

Sorry for the trip (and diversion) down memory lane. Back to lights.

Finally new UI! :slight_smile:

Not those have all I need. Would it be possible to buy those drivers separately?

How about Bisquick (edit: This was totally a joke, no disrespect intended)? lol Café au lait? I think when I get mine, I’ll just call it “AWESOME!!” :heart_eyes:

Demitasse?

Mahalo to everyone involved!

In general, it is quite interesting firmware.
I’ll try it now flash in the Convoy C8.
From the description, I did not quite understand how the adjustment, but I think I can figure out.

What FUSE?

Why did you decide to abandon the separate control group of chips AMC7135?
1*7135 in the fifth leg, 2*7135 in the second, the other on the sixth leg of the microcontroller?

I like Bisquick, but I think there are some trademark problems there.

Bistroy ?
I like what is done here, true customer feedback engineering (if that makes any sense in my oh-so not native language…)
I like Bistro UI but can’t really enjoy it because of my uncontrollable taste for Turbo mode with 30Q…

Only thing that C8 needs now is remote pressure switch and we can actually use it for hunting :smiley:

It should, actually. FET drivers just crowbar the battery across the LED with minimal resistance, measured in milliohms (mΩ), so the voltage they’d drop would be negligible (Vf ~ Vb), vs 7135s which drop the difference between Vf of the LED at that current and the battery voltage, or about 0.1V (100mV) minimum. So 4.2V from a fresh cell and 3.6V Vf is a 600mV difference (vs much less with the FET).

Drive a red XP-E (~2V) with 7135s, and they’ll all join hands and limit current by soaking up all that excess voltage and burning it off as heat. Crowbar the battery directly across it with a DD FET driver, and the poor XP-E will die a horrible fiery death.

Mmm, I saw from the pix it’s (thankfully) not a mirror-finish. Nice…

Flashlight-porn… :smiley:

“unistro”? :smiley:

“mini-stro-ni”? (Okay, booooo…)

Finger buffet?
Snack bar?

If it can be easily added, why not make it a option. $1 extra for cut out slit tail cap. I think it would do well. For those that have tried cut out slit tail caps, you won’t go back to regular ones.
No matter how recessed the switch is, you should still be able to turn on with gloves. But the cut outs just make it so much more comfortable and easier.
