Nope, thatās the bad thing about this mod :zipper_mouth_face:
The driver I am using (from led4power) doesnāt have charging, so it doesnāt work :zipper_mouth_face:
I kept the driver, though, in case I want to reverse the mod, or in case I can build a charger with it! (not sure howā¦ :person_facepalming: )
Looks cool, which light does that fit in?
The wife got this little light for me off of Ebay a year or so ago. Canāt remember for what occasion. The stock emitter was not really my thing. I had replaced it with something, LH351 of some sort I think. I like the little thing but itās not exactly a great EDC light. Well I had it apart for the second time swapping out the emitter yet again. This time to a lost but now found 219b. I had a few extra Reylight Pineapple AA pocket clips looking for a new home and what do you know, they fit the tail cap on that little light just perfect. Besides making it easier to carry, the clip also gives you something to hold onto while working the tail switch. Itās glass smooth and very slippery with even the driest of hands.
Nothing fancy other than that but, what a difference those two minor tweaks made.
Lucky you. Sweet little light. I would already be happy if mine bought me a Corona-dud.

After getting together the parts I needed I had a lot of trouble trying to get this lighted tail to function properly. After a lot of help from Mr gchart I got it working :partying_face:
Going from a press fit rubber boot to a retaining ring and battery indicator tail this light is on a whole new level now :sunglasses:
well done!
Thanks djozz. I was definitely on the learning curve for this one 
very nice!
me wantā¦
Sorry I only checked this out now, but this is beyond my capabilities, though I understand it (I think??). I can buy OSHPark PCB's but can't lay them out. I can reflow but I'm way short of an EE with the ability to do circuit board designs, and make decisions about when a cap or resistor is needed, etc.
I think what Mike C did was simply wire up the 5 pins of the MCU we need to reflash firmware to a USB connector. But of course he laid out the board to properly design it in. I think it's that simple, but not sure. Maybe other components were needed, like pull up resistors or something. Boy, sure wish that was more readily available - it could apply to many lights, but think each light would need a custom designed driver PCB.
Yeahā¦I wonder if Mike used USB merely as a physical interface or did he pay some respect to the specs. And if he did - then how much?
My guess would be just used as a physical interface. But even as a physical interface, to re-flash is pretty dang useful.
Indeed
Thatās a great looking light youāve got there, pinkpanda3310! Good job persevering through the electronics troubleshooting.
Both of you are somewhat missing an important detail about that driver. Itās using an ATtiny3217 which is a 1 series MCU. 1 series supports āone wire programmingā which is UDPI. To flash it I only need + for MCU power, GND and the UDPI signal, thatās itā¦ Besides GND I only use two connectors from USB for flashing, + and UPDI. The The others I use for the charging chip and an external E-switch for my bike light.
Yep, missed that totally 
. I still don't see it mentioned in the post, but of course you don't have to. 
Oh yeah, you are absolutely right about that. I didnāt even mention it was the 3217 in that post :person_facepalming: Iāve posted about my use of the 3217 in other threads but it is impossible to keep up with everything going on here. The only give away is the photo of the flashing kit, but I realize you have to be some what familiar with the 1 series to recognize it.

Wow 
that looks awesome 
A few weeks back I had a failed attempt to mod. Pried it open to hopefully answer some questions regarding the Manker E02.
