uSupply
« on: September 09, 2012, 08:27:03 am »
hey guys, is Dave going to sell the uSupply as a kit soon. i really want one, because my manson power supply isn't quite adequate.
I'm sure others would buy one too.

from his video of the dfn soldering i am almost certain he is going to sell it as a straight product like his ucurrent (thats why all the smd) as for how long it takes to get to a selling point only he would know,

i thought that board in the qfn soldering tutorial looked like the uSupply

From talking to Dave today, that's the plan, to sell it as a complete product. Still, being OSHW there's nothing to stop you building up a board yourself.

Is there a target launch date of any sort?

Do you reckon it would be available before years end?

I still have to write the software, test it, probably do a revision of some sort. Then maybe build a pilot run and get it production ready, then maybe do the Pozzible video etc and get the crowd funding etc.
Your guess is as good as mine...

Dave, Are you collecting names or just a count of folks that would like to purchase the usupply?  A simple count could be used as the basis for a crowdfunding as in " I have XXX people who have already expressed interest in purchasing......" 
Just a thought.

Hello!

It is really interesting to observe how uSupply project is developing.
It really like the project page, where all basic specifications and scematic is in one place. Really can not do open development of project in forum only, as I have seen often. There just has to be one owner of the project who dictates the specifications and makes design choices. If the schematic is fixed, it may happen that people in the forums help to get the project finished sooner (and with lower cost). Specially if the project documentation is good enough and some version of board layout and early software version is already available, so that it is possible to already build and test something. Better of cource if layout is suitable for home making.

Dave, can you add links to forum topics about the uSupply to the main project page? So that it would be clear where is the right place to discuss about. Just wandering...

Also looking forward to see your solution with rotary encoders. Is it going to be speed dependent algorithm... it must be.
I am currently researcing about using rotary encoders. Speed dependent algorithms make them feel very much better!
 I'm using PIC and assembler, but it does not matter, algorithm can be implemented in different programming languages.
May be add this to Spec sheet also?

Regards,
Teemo

There are already some versions out in the net developed form some revision of Dave's design.
For example: http://qwertyboydesign.wordpress.com/projects-2/digital-psu/  I do not know if the person who made this layout, have shared it in here forums. Also unclear if he has made firmware.

As my first post, I'll add my voice in cheering Dave along on this project. Looks awesome, and would love to build a usupply kit in 2013 :)

It won't be a kit. There is just no place for an SMD kit of this sort.
Of course, if you really want, I might sell you a blank PCB and you can go for your life.

I honestly believe this is nonsense. I have almost no experience with SMD soldering and I would not hesitate to buy a uSupply kit.

But hey... instead of arguing why not voting ? You can make a poll in the forum so we can vote if we would buy a pcb at $x, a kit at $y or a device at $z... (all being reasonable prices I would buy a kit)

The question is how much extra over the cost of an assembled board are you prepared to pay for a kit? Twice as much?

Assembling kits  along with all the documentation is a lot of work and smd would make it probably be more work then through-hole components.

Then there is all the requests for missing parts because someone did not realize they dropped a smd resistor onto the carpet. I assume you would expect Dave to pay for the cost of shipping missing parts? It is very expensive to post items internationally from Australia.

Would you expect Dave to be able to supply lost or damaged components at a reasonable price? Would $30 for a single smd resistor + postage be a fair price or would you be expecting Dave to do it for $3?

Then how many kits would never work? If Dave sold kits and half of them never worked, it would not be a good result, no matter how well meaning people are. If he sells assembled and tested boards, then 100% of purchasers will receive working boards.

Would you expect Dave to answer emails about how to fix a non-working µSupply board, or even to offer a service to repair a board? Usually when a kit company offers a send-it-in-for-repair service, they just replace the unfixable mess from the customer with a properly assembled board and in this case, the kit price may have to include the cost of a replacement assembled board right from the start.

The cost to machine assemble a board would be less than the cost to kit up the components (i.e. cut them from tapes, label, bag etc.)

I may supply it almost fully assembled. i.e. just solder the connectors and battery holder on and assemble the case. All the SMD parts come soldered on.

I agree that kits are probably a bad idea.  However, bare PCBs would be nice.  I would actually like to give soldering one of those a try.

...but only if there is enough interest to make a plain PCB worthwhile as a separate item.

Plain PCB's aren't much of a hassle, as you can usually slip them international post as letter with no customs form.
I would not expect much call for it though.

With all these soldering videos from Dave, I want to try some smd soldering :)

But as he already said... unfortunately there will be no kit :(

If Dave is offering the schematics of that µSupply later on like with the µCurrent anyone should be able to do their own PCBs and have it manufactured by some company in whatever country. No matter whether you want SMD or Through-Hole parts. ;-)

I am curious about the videos later on. I think the supply itself is a nice thing but learning how to actually build and design it is the part I'm interested in. ;-) There are round about a dozen videos for this supply already but I WANT MORE!! ;-)

Dave: Keep on the nice work!

I start the build of my own version of this machine:

http://vpapanik.blogspot.gr/2012/11/low-budget-manual-pick-place.html

It seems to work very well in the video.

Maybe with help of this machine, the SMD kit would be a great idea.
