Custom 17mm 5Amp PWM-less linear driver-preliminary

For awhile I was thinking of doing a gb for California members but now I’m thinking of getting 5 just for meeee!

I'm still waiting for some parts and pcbs,but I have serious trouble with pic12f1840-e/mf availability,it's out of stock even on microchip page,so I ordered them at reichelt.de (2x price just like everything in EU),but guess what,now they're telling me they don't have it in stock.

So I need a trustworthy BLF member from USA to buy them from newark.com,and send them to me with fastest conventional shipping option(not DHL,UPS,Fedex...). Prize is 40$ or 5 finished drivers.

I suppose that member who is closer to Newark will get package faster,so that member has advantage.

:_( If only I was in the USA! I would buy them for you in a second!!

I am in for 8 of these drivers if they are around the $15 mark.

how many do you need?

NEWARK won’t ship them to you?

100pcs,I don't see shipping option outside of usa,but based on shipping price from mouser (120€) and digikey (120$) to my country,I don't think that newark will be much cheaper.

For Avnet shipping to me is 90$,future 60$,+extra charges by fedex.

I’ve ordered from Newark but it takes a week to get to me. I’m in if no one else steps up.

I sent you a PM. Newark usually gets to me in two days. From here to you will be 10-14 days though.

I do not need any compensation for helping out.

I will send out the parts to led4power on Saturday. Expect 10-14 days for them to arrive, so it's in the works still, just taking a little longer due to parts availability.

O-L,

That’s good news. Thanks for stepping up, especially with your uncertain future. Once again you prove that you are a driving force here at BLF.

You just dont see people these days going out of their way to help someone out, especially someone you don’t know. O-L you certainly are a stand up guy!

+1

Personally, I would have taken three and GAW’ed two of them. But that’s my opinion.

I have never shipped anything overseas, so I didn’t volunteer. Wouldn’t want to muck up a $100+ investment because of inexperience.

I’ll gladly chip in to that if it happens.

I got all the parts,and assembled 2 pieces for final check,and guess what,I got fake microchip op-amps(from smart-prototyping)!

They behave like normal/cheap non ultralow offset op-amps,so moonlight with them is too high and non-consistent (because sense voltage at that current is in uV range,and those fakes have input offset error much lager than that). Luckily,I have few genuine pieces in genuine package,and there are many easy too spot differences(maybe I'll post some pics later).

Now,I have to order them from local farnell distributor ($$),so + 4-5 days more delay.

F***ing unbelievable.

What method are you going to use for selling these? Will you be selling them through a thread on here?

:_( Sorry this happened led4power…

I will open separate thread.

Wow that’s disgraceful.

Don’t get discouraged :slight_smile:

Not sure if this has been mentioned before, but can this be modified for MT-G2?

Ouch, that definitely sucks. What an embarrassment for Smart Prototyping (and what an inconvenience for you!).

Well it can,but it's just too complicated,it needs resistor divider+op-amp as buffer+expander board.
