Even if I don’t know how to programme, I could learn and a cable would be handy in that case !
I’d buy one from you if you decide to make them. And thanks in advance for the proposal! :+1:
Ok, I already ordered 15 boards and I’ll order some other necessary parts, I already have a few micro USB to TTL boards, maybe I should get some USB-C ones next.
You mentioned that heartshrink is optional, but in any case some insulation isn’t since touching the RX connection can make the programming fail in my experience.
Got your adapter today gchart. Thanks for the quick work. Now to learn the intricacies of Buried somewhere within this thread is the necessary software and some instructions on how to use it. Would you mind linking to that post in the OP to help us all out? Thanks.
I guess I need to publish a straight-forward set of instructions. I haven’t done exactly that yet, but I do have a ton of info here: Adventures in TinyAVR 1-Series
Basically, you need to…
Make sure you have python3 installed on your computer
Install “pip” for python3 (it may already be installed if you have python3)
Use pymcuprog on the command line to flash the hex file. I recommend doing an erase before writing the new hex file. I have sample commands in the post I linked above.
As an alternative to #5, instead of trying to find your serial port and typing out your own commands, I have a python script here that you can use to issue a simple command like “flash-1616.py anduril.hex” to help do the dirty work.
Much thanks to gchart and zumlin! Once I got windows to install python properly, it all just worked! gchart, the little python script works very well also.
Also, just get gchart’s pogo adapter with the resistor and diode on board, it is a bargain!
What other lights flash this way, is this the first?
:+1: This is the first light with this programming format. Sofirn (and maybe Wurkkos?) seem interest on using it on more lights, so I think we’ll probably be seeing more of it soon-ish.
So is the flash-to-off quirk a widespread issue or not? I have yet to see it on mine and I’ve been using it nearly every evening since I got it.
I have another niggle….this light is a PITA for tail standing. I was commenting in someone else’s thread (tactical grizzly maybe) where they said it tail stands well. I find that the surface needs to be flat-flat and pretty sturdy or else this light is liable to topple over. I sat it on an old pc box and it kept falling over….got out an angle gauge and it was about 4.5°. lol. There’s only something like 30% of the circumference that is a footprint for contact - they took way too much material away. If they come out with a green magnetic cap I’ll pick that up. For now, I put the Convoy T2 16mm ring magnet back in it…sticks up a little above the ears so it’s at risk for fracture but it helps the light tail stand properly.
Other than that I like this light a lot. Picked up some brass tubing 9.5mm x 1mm and will slice off some button washers soon.
Try turning it off from level 2 out of 7, stepped ramp, advanced mode with a 14500 inside. The stepping down before off bug was reproducible that way, but I have only seen the flash once or twice before I fixed it with a firmware update.
