Dave, is it possible you could test/review the quality of the DAC/ADC in the Tiny Gecko board you received?

Yes!M

Post number 4000. :P

Don't exaggerate!
Good chance it'll make #400  :P

Dave.

A quote fail. :P I was refering to number of posts on the forum, not the blog videos.

The twists and turns are what make it fun to watch.

Yep, but not so much for for the person making it!
It can be rather embarrassing because some things can be stupidly obvious with hindsight and a few more moments thought.

Dave.

But actually, that's not your fault, but the fault of a culture, that does not reckognize the value of failure in any learning process.
Remember, what Jerri Ellsworth says there - and she's so damn right and to the point, IMO. :)

So what is the status of the PSU project ?

I have not seen an update for a while. I hope it will come to a successful end :-)

Pretty much the same place it was last time :->
It's almost certain you'll see a spin-off supply project before the conclusion of the current one. That's guaranteed to piss off a few people! :P

I hope so too. It is certainly not abandoned, but new videos for it require several large leaps in terms of project completeness (e.g. the new re-spun board) so won't happen overnight.
That's why the other project will likely get a look-in first, there is fresh material there to be mined...

Is it the programming?  Last I kept up with the PSU series it had a couple of different buses to talk to a handful of different subsystems, if I remember right.

No, I have to re-do the PCB to SMD. Major changes.
Plus I need to think about stuff as usual... is this the best way etc...

Great! A simple update video explaining the current status of the PSU series would be cool. Let us know what the process and thinking is for the spin-off, as well as what the future of the original PSU is.

Ah, what the heck, a sneak peek. But actually, it's an old peek.
You'll see.

TOO COOL! 8)

I can't wait to get one... well, I can now 'cause I bought a used Instek PST-3202 PSU off ebay waiting for the other uSupply.

Though, I can't wait for the details!

Looking forward to the next PSU installment...

Thanks for the pic, Dave, and I will probably pick one up when they become available...

Dave, loving the PSU series, have you posted the code for the Rev B PSU anywhere it would be great to get a look.  The time circuits have fused so travelling to the future is out of the question right now.

Breaking news! *alert alert*  :-X ;D

https://twitter.com/#!/eevblog/media/slideshow?url=http%3A%2F%2Ftwitpic.com%2Fap5usz

I was interested to take a look at it.. and it seems like it's indeed the SMD edition. But I suspect it is both PSU's combined (both a PC powered or battery). I recognize the same MIC2253 boost converter as in the supply rev C, an SOT-223 LT3080 (does it have enough cooling? Oh, too bad silkscreen doesn't work too good on bare copper ;) ). I think the MCU is ofcourse an ATMEGA168/328 with the 6-pin ISP AVR header. Battery charger probably left on top..
Seems like it has PC control because of 2 opto-couplers. I think a MCP2200 is used, or a recent FT chip (FT200 series?).

I'm very interested how much I guessed right  ::)

Some right.
ATmega48
I got screwed on the FT230XS chip, no longer in stock anywhere it seems  >:(

I hoping to have something working for the Electronex show.

I think there was another thread where this was discussed.
