FS: Jibs Linear Drivers

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

Jib I never followed up from this post when I thought I blew your one of my 1.8 jibdrives. Sorry about that man... Turns out it was the diode that I blew out when changing up the batteries back when I had and not your driver.

I've since reinstalled that driver into one of my Solarforce builds and it's working fine. It meters right around 1.8A depending on what lens I'm using too :beer:

Awesome ... good to know its still tickin'. I wonder if the diode was ready to fail and it just happened to fail at the time you switched cells. Linear drivers are very good at filtering spikes, especially with 10uF's on the input and output.

Thanks for the update :beer:

I agree, especially with the caps on both ends. Unfortunate timing seems to have been the case though :beer:

Got my drivers yesterday! Thanks Jib!

I think I'll be picking up 2 500mAs later today, these looks pretty solid.

I used the 1.8 amp driver with 445 . I was very smitten with the result.
It is true that the heat produced is a lot. I cut a few pieces of cooling fin off of an old GPU .I affixed them to the LM resister and the 2 smaller resisters with sink apoxy.


Great job - wolfram



Oh by the way when are you going to sell your buck driver?

Finished my build with one of these (444 version) and with proper Heatsinking it performs very well

Thanks! I dont have a buck driver in the works, but Im waiting on a better PSU to test my boost driver. But even if the boost driver is ok, it will be at least 3 weeks before I have some available for sale.

Awesome ... do post some pics if you get a chance.

Heres a picture of the Driver sinked,

^^^ Nice drop in!

Thanks jib, :beer: I got the HS design from one of LazyBeam's builds.

JibBoost is alive!

Sweet. Let me know when I can order 1 or a few of the boost drivers. What power variations will you sell? I have 11 kryton grooves coming to me soon so I will need a few for single battery use.

The only purpose for these is to break the 1.5A barrier on a single cell, so initially it will have set resistors for 1.8A(+/- resistor variance). I also hope to get this up to 2.8A to power XML LED builds.

The first batch will be available in about 3 weeks.

I hope you do make a few other power outputs at some point. At what pore output do you think these would require heat sinking for a 1 minute on time and one minute off interval inside a bigger laser host like the kryton groove? It would be great to find a high power driver that already comes with or doesn't need a heatsink. I would pay extra for not needing to heatsink them myself depending on how much that would be.

Consider me in for at least 3 to 4 as long as they aren't too expensive on release day.

Im going to have to recommend heatsinking. The IC reached 165˚F in 45 seconds. A little slug of aluminum or copper epoxied to the IC should be enough. Unfortunately I have no means to manufacture these slugs, I usually break off fins fom old motherboard heatsinks for this purpose.

Sweet! I have been thinking about the JibBoost a lot lately; hoping that they will be available soon. Can't wait!!
