[Preview] EDC18 by Lumintop - FIRST LOOK of a Anduril sideswitch EDC flashlight

@M4D M4X

Can you please weigh the EDC18 when you get a chance?

I feel the 53g spec on Banggood is incorrect, copied over from the FW3A specs.

I am familiar with the pinouts on the Attiny85 and the Anduril code.

I did not find this info about the EDC18, but I can deduce it based on the hardware.



my kitchen weight gives me 75g (prototype)



have you watched my video?

1. yes
2. i am not sure
3. yes (green bunny)
4. its on in "standby" so: yes

Concerning #2, Anduril can certainly control the switch light with options like off, dim, bright and blinking. We see this with other side switch lights using the same driver parts and Anduril. I see no reason why Toykeeper would disable this function in Anduril. There is no reason to. I have to assume it is controllable. (Better to assume it’s not controllable, waiting for confirmation)

I don’t know if your prototype can do it, but try this. From Off, do 7 fast clicks and see if the switch light changes. To cycle to the next option, repeat with 7 fast clicks.

Here is the newest Anduril cheat sheet.

You can try the color change as well, but I doubt they installed multi colored LEDs for the switch. 7H means 7 fast clicks and Hold the button on the last click (iirc).

Got in on the preorder thanks. Not that I need another light :smiley:

I think the bunny is wired to the battery

it's not controlled by Anduril

Fireflies also had only 2 of 4 leds in the switch controlled by the UI

(also my sample only has one Lockout brightness)

So what did I preorder?

Yes, I did watch the video M4D M4X. Thanks for putting that video together. However, it didn’t cover what the switch light actually did. It looked like it was illuminated.

Sounds like there is still some confusion on exactly how the illuminated switch function works.

i hope i get one of the first sale version lights to clear all questions

I got in on the preorder! Thanks for the code!

:beer:

Nice light, is it mod friendly like the fw3a? Doing reflows to nichia possible?

Hmmm, I guess they can choose to do it that way. It’s simpler. I know pin 1 on the mcu is unused. I would think it’s capable of a switch light output. Maybe not. I’ll ask Toykeeper if she wrote a version of Anduril for this light.

Yes, there are 2 basic ways to send power to the light. Either constant battery power or a PWM signal from the MCU. I will ask the software writer. It’s possible Lumintop made their own decision.

Until we know for sure, I would assume it stays on all the time that power is connected. (I actually like this because you can easily tell if it’s manually locked out or not) I will report back if I learn anything.

Okay, I found out that pin 1 is physically not capable of controlling a switch light.

This means the switch light is a simple battery direct led. It can not be controlled through Anduril.

Fireflies probably used a 2 channel driver which freed up an extra output pin to control it’s switch light.

There are pin layouts which allow 3 power channels plus aux leds (and ofc the switch input). For example the ROT66 is 3 channel with FW controlled auxiliaries, as is the FW3A (when upgraded with the lexel aux board) as is the E07 and I presume the PL47 though I don’t have one [yet].

Fwiw I’ll be adding a lexel v2 aux board to my EDC18 controlled by anduril.

Cool.

If you have time, maybe we can figure out all the pins on the FW3A.

I know pin:

1 - for flashing
2 - switch signal
3 - FET
4 - ground
5 - 1 x 7135 (bottom right)
6 - 7 x 7135
7 - voltage sense?
8 - main power in (top right)

I’m not sure about pin 7. I wonder how you can have 3 output channels plus still have a controllable switch light.

We normally don't use the voltage divider circuit for 1S batt configurations but you do need it for 2S or more. So pin #7 is free. Normally it's used for a switch LED or equivalent when you have 3 output channels.

So in theory, they should be able to control the bunny LED.

Unfortunately pin#1 is off limits to us with the typical USB programmers we use. If you get the AVR Dragon kit, you can actually reprogram the chip utilizing pin #1 an an I/O pin. Only one around here I know of with the Dragon is Richard (MtnE).

What is pin 7 doing in the FW3A driver? It seems to go through R4 and C4 and then the FET/negative wire from led.
