It should be able to work without the bottom side 7135’s but would need the right mode group selected to do it.
Lexel makes drivers that are ready to install in small quantities.
I generally don’t bother with making drivers to sell unless I can sell at least 25-50 of it, just not worth the setup time for less then that personally.
Thanks for your reply TA! I get what you say, and I would need to check with Lexel if he could make those drivers as it would imply more work!
I also know that MTN has those flat sided drivers ready to install, but I didn’t see them with Narsil or Anduril, only the Ramping IOS from the D4 on them.
I’ve been using the new TinyAVR Series-1 chips (412, 416, 817, etc) in some recent designs, including my "smart" tailcap.
They’re pretty neat, but the difficulty is that pretty much all flashlight firmware up to this point is for the 13A / 25 / 85 chips. I wrote a new barebones NarsilM-inspired firmware for the Series-1 chips earlier this week. And last night, I converted Tom_E’s RampingIOS to run on them (not fully tested yet though). I hope to be designing a single-sided 5A linear driver around these chips pretty soon for the Emisar series (with the D1S + Flat White in mind). I want to confirm another design is working properly first (a 17mm single-sided linear 3A driver). I really like the single-wire debugging and programming that the UPDI provides. And it makes the “programming key” pad footprint smaller and more manageable. They have a lot of good peripheral options, too: internal VRef and temp sensing (which the 85 does have), RTC, TWI/I2C, 16-bit clocks, flexible low-power options, QTouch, etc.
AVRDUDE has added support for UPDI, but not in the published compiled versions yet. So if you want UPDI, you have to compile it yourself. I also ordered the JTAG programmer that El Tangas is working with, but also haven’t tested that yet. For now (until I get fully up to speed) with the Series-1 chips, I’ve been using Atmel Studio 7 for flashing, done via a ATtiny416 Xplained Nano dev board set up for off-board programming.
Whaaat? Who has removed the picture link in my above post? There Gimli was, asking an important question concerning the above referenced cheap knives who wouldn't have lasted even 5 minutes in Knife or Death. :-D
If you wanna check it out, click/tap (not safe for work ;-) warning).
The Manker Godmes was a Bluetooth controlled flashlight that responded to sound, or at least blinked to music. Ahead of its time. No longer in production, though. I just thought I’d mention a cool light most folks don’t know about.
One question. Do we have a driver available on BLF that would be able to drive 2x 3V or 6V leds (seperatly and/or together)?
Or 2x tripples with SST-20 leds (again seperate and/or together)?
Only gathering information at the moment.
