After talking with Matt, Everett and Brian (WarHawk) about driver options the plans are finalized and the rest of the parts for these ordered. The drivers will be linear FET drivers (not direct drive) and are even smaller than the Tiny 10 /10dd’s! They’re called “”Tiniest10”:https://oshpark.com/shared_projects/TAoalgqb’s” and are single sided drivers with a + battery contact on the bottom for direct install. They run a 6-pin PIC uC which Everett will be providing for me with a simple 3-mode off-time based UI (L->H with no memory)
I’ll be limiting max current to somewhere between 500-800mA (so they should make between 250-350Lm OTF), I’d love to drive these to the max but I’m hoping they will be usable as an EDC, not just a little hand warmer so current in the tiny stainless steel light has to be severely limited.
Calvin sent a selection of XP-L’s, 3 or 4 tint bins I believe, and it was decided the engraving needed to be all in one location so it reads “BLF OSHPark”
Here’s Djozz’s package ready to be packed up and sent tomorrow. It’s got 3 old style BLF17 boards, 2 each old style 10 and 15dd boards, 2 XM-L2’s and XP-E2’s he bought added on my last digikey order not sure the bin’s/tint’s but I know they’re warm (euro digikey has $25 minimum shipping fee’s) and 2 more XM-L2 S6 7D3 warm 90+CRI I have a bunch of (the individual ones). Also has 5 sets of 105c parts, 5 IRLM 2505 FET’s (for the 10 and 15dd’s), 5 off-time cap’s, some stickers, an XML-RGBW sinkPAD and 5 programmed 13A’s flashed to his spec’s (3 mode with a star to add moonlight, off-time no memory L-H, no turbo timer).
Jos, this stuff will be in route to you tomorrow, I’m not sure the tracking situation / expected transit time but please definitely post when you’ve received it. Thanks for everything you do for all of us here at BLF!
The link for the board is in his post…it’s teeny tiny and single sided!!!
It’s not ATtiny, it is the PIC code so if wont compile in AVR Studio, besides we don’t have the hardware to flash the PIC
Excuses, excuses. I would hardly expect any of that to slow you for very long. So if the boards are available, how does one acquire the programmed pic? Which thread? This one?
Hehe you got me…I am still trying to get good at the ATtiny, I would like to get into the PIC stuff but it is even MORE Greek to me than the code for the Amtel
Amtel does make a small 6 pin version like the PIC called the ATtiny10
The ATtiny10 and PIC are pin compatible I think. I know VIN and GND definitely are. You just have to check and see if the pin used for PWM is. The only thing the PIC has over the ATtiny10 is that you can do low voltage protection internally with the PIC. The Attiny will require externals components and may not have enough pin space.
Also, in regards to the tiniest 10 - it could be ghetto'd into being direct drive by removing the transistor and soldering a few bridges here and there.
I like the idea to find two members who do something for the forum and throw another one in the game: DrJones.
Tido and he started in my opinion the driver programming for dummies. Without their work and firmwares a lot of us don't have clue about these things. DrJones offers a few famous firmwares, which are used or modified from others to get a great firmware. This are the reasons why I suggest DrJones.
In any case these should be slick little pieces. Dr Jones is a good candidate, he helped steer me in the right direction when I was doing my own high voltage mod. So did Texaspyro and Pilotptk for that matter.
Original posts updated again, first time getting my hands on XP-L’s but I can’t use any of them for my own stuff. Guess I either have to buy a few more or wait till the lights get here to play with them.
Hosts got here today, remember I paid $6 /ea for these, these things are amazing compared to my SingFire clone from the GBGB. Brass bezels that don’t block part of the reflector. A hole for lanyard attachment (no clip ), the reflectors are large enough for the XLP dome (old lumens was in on it too, he was gonna enlarge them for me but now I don’t think it’s needed).
Center is my clone.
Plus they had XP-E2’s !
I’ve swapped a N.119 in mine, you can see how small the reflector opening is on it.
Output is 31/8 AAA, 177/155 10440, oh yeah they’re 3-mode h/l/strobe(expected single mode) It’s almost a shame to rip them apart for hosts (almost, plus having the XP-E2’s will be cool, I’ll have to find a project for them)
One minor negative is they’re forward clickies but oh well.
So now all I’m waiting on is being able to order the BJT’s / rest of the FET’s I need to build the drivers from digikey and the MCU’s tterev3’s hooking me up with then Just gotta decide on the current level, hopefully I’ll have these ready right about the end of the month for my new website launch.
Sorry for the late reply, I hadn’t seen the questions about the source code until just now! You guys guessed correctly, these will be running an adaptation of the example code I posted here
although recently I’ve been thinking about the possibility of making some special additions to it…
either way the final version will be open source and I’ll post it here
I have some code ready for a proposed UI for these lights. It may not be the final version for the giveaway but it’s what I’ll be using on mine. It’s a two mode UI: maximum brightness and user-configurable brightness, and it includes a smooth ramp down if the battery dips below 3.0V. All controlled through power cycle. I’ll do a video demonstrating it soon, but I have source code ready now. What’s the best way to share it on your launchpad site? Should I email it to you?
Email, bzr branch+push to LP, send a git URL, whatever. I should probably just move to github since it’s more widely used and makes this sort of thing easier.
I highly recommend anyone wanting a mod host stat with the SingFire clone. Much much better host for a mod, easier to open and has a real pill and a reverse clicky (better for a multi-mode UI).
I put up a video of the firmware I created for these lights in this post. It’ll be up to CK if this version goes into the giveaway lights, but this is the way I like mine. It’s all open source and can be tweaked easily, so I hope BLF people can use it in other lights as well
