Re: FS: Jibs Linear Drivers - 500mA, 1.3-1.6A, 1.8A

If you want a stable 1.3a jib will modify it but if you want around 1.3 unsinked and around 1.5a sinked then just take a normal driver, it wont go anywhere near the maximum current for a 445 diode

Re: FS: Jibs Linear Drivers - 500mA, 1.3-1.6A, 1.8A

I got my 2 501ma drives today and am curious. On 1, the 2 capacitors under the 117 are soldered together in the middle. On the other, the horizontal capacitor is soldered to both the pad it's supposed to be soldered to and the pad that the right leg of the 117 is soldered to. This is looking at them with LD- bottom left and LD+ bottom right. Are these going to work? I don't want to lose another 12x. I realize the caps are just there to stabilize as these are low drop out regulators but that's important to me. It would be great if I had a capable camera, but I don't.

If they are connected in the middle then its fine, they are both connected to the ground plane there. And its ok for the horizontal one to touch the right leg, they are both connected to the Vin plane. The important one is the left cap, it can not be touching the left leg.

Great! Thank you. I was hoping that was the case

Re: FS: Jibs Linear Drivers - 500mA, 1.3-1.6A, 1.8A

I just blew out one of my 1.8A jibs by using 2 18650s instead of 2 16340s as I have used before in a 445 Solarforce build w/ an extension tube. All these batteries are 3.7V, the 18s are AW 2600mah and the 16s are palight 880mah. What am I missing here? It's probably a common mistake I'm overlooking but since when does mah make THAT much a difference to kill a 1.8A 9Vmx driver?

WT*!? I test my 1.8A w/ a 2xIMR26650 battery pack because the bench PSU can not deliver enough current. 2 18650 should not have blown the IC. Did it physically blow? What have you done to confirm the driver is dead?

Re: FS: Jibs Linear Drivers - 500mA, 1.3-1.6A, 1.8A

I'm not positive what happened to it, I was testing another method last night that uses 2 18650s and when I powered the unit on I just got 1 short pulse. Following that it just doesn't power up.... no dim blue, no flicker, ect. I haven't tested on my dmm yet, haven't tested the diode (this was late last night, went to bed shortly afterwards) .....but I will today.

The driver worked fine before this though, this is something I clearly did. This is not a case where I used a new jibdrive and it just failed, I did not mean to leave that impression. Your driver was fine until I did this jib, I just don't know why or how it happened, don't want to do it again. Lucky me I still have 6 or 7 exrta jibs to choose for replacing, but WTF is right. I will follow up with what I find after I remove & test the driver.

No worries, thats not the impression you left, Im just as curious to find out what happened, since these IMR cells that I test with can provide up to 10Amps.

Re: FS: Jibs Linear Drivers - 500mA, 1.3-1.6A, 1.8A

Yeah I'm curious also.... I have a lot of lasers that are interchangeable with 2 18650s, and/or 2 16540s/CR123As using spacers and extensions, ect. As long as I'm within the reasonable Vin with the driver being used I would think the only difference would be a longer battery life with larger batteries. That's the impression I've always gone by regarding using different batteries.

I will share my testing results when I get to it - so others can possibly point out any errors or cause I'm overlooking :beer:

Proto PCBs are here for the boost driver ... still waiting on parts to arrive.

WOOOOT WOOT WOOT WOOT!

Why is the thread tag jake is gay? I can take wild guess who did that!

wtf...jake is gay... lol

anyways sweet design for the boost driver. one question is where is the V- input. usually theres a ring around the bottom side of the pcb that acts as V- input.
