Have looked at data sheet but have not used the Seiko S882.

Iron

hello all from Edmonton, Alberta.

 

Iron

thanks once again sir paul for a wonderful presentation in giving us information for the subject, ENERGY HARVESTING, well informative and excellent presentation...

thanks also to the DIGI-KEY and DESIGN NEWS for giving us continuing education that will help us grow and added PDH through giving CERTIFICATES...

goodnight!

i am now to slide 17, coming to end...

ok, i am now with slide 3 for the lecture...

i am now about to download the educational material for today's topic...

good evening once again sir paul, here i am for your last episode of energy harvesting...

thanks Paul for a very informative class

Iron

last catch up for this class

Iron

Thank you, Paul!

Iron

Nope, have not used this particular chip...

Iron

Great to have access to the recorded sessions!

Iron

Missed the live lecture...

Iron

Taking the class offline...

Iron

Even cuaght up on this one!

Iron

Thanks for the archives

Thanks for the course Paul

Iron

Thank you very much Paul, Great Presentation.

Iron

Thank you Paul! Lets hear you again.

Very informative lecture

No use for S-882Z device

Testing Log in

 

Iron

Seiko also makes, or made, single mode fiber optic pigtails for splicing .

Very interesting material!

 

Iron

good day to all :)

Iron

a lot of the interesting ideas

Iron

good info,,,, thank you

Iron

Thanks Paulin for a nice series and thanks Paul for bearing with us. Take care all

Iron

Thank you for listening everyone.  Its been fun for

me doing this particular course.  I will have another

new topic in August.  See you then!

Blogger

Thanks Paul!  Excellent presentations.

Iron

Never knew Seiko made semiconductors.

Ohh yes they do.... They were (many years ago) one of the

first to make a whole personal computer on a credit card sized

module.  They've done some very agressive designs!!

Blogger

Yeah uF for a Battery... confusing.

Got to try to read-between-the-lines....

Blogger

On SI units:  I am not trying to advocate for any unit

type, simply - we must select one.  SI is good, but being

a New Englander, I do prefer english units for weights and

linear measure.  That is just personal however.

Blogger

Paul,

Thanks for a great serries.  I thought I knew a lot about this topic and I would say (Humbly) that I do but I am amazed how it has progressed .  Thanks Paul, I can begin to be somewhat knowledgible again.

Iron

Paul - Re-survivor or reservoir.  I will take either.  Thanks again.

Iron

Re uF battery, seen, a cap can be used too.  It seemed a surprising spec for a battery... ^_^

Iron

Overcoming the foward voltage drop -

yes that is the problem.  There are a

few special parts here - and the magnetics

idea is a way.

Blogger

Thanks very much. Paul.

Iron

Ahhh I see it, on slide 12 - yeah, its saying

that the 'battery' can be a 100uF cap!!  They

call that the battery - or better put - the energy

resorivrior.   (I am not a good speller)

Blogger

I appreciate knowing about these devices.  I had been trying to figure out how to overcome the forward voltage drop of the bridge rectifier at the input (slide 3). I was envisioning round-robin charging capacitors to a few mV and then connecting them in series before emptying them into the load.

I am ready for my Starbucks!

Iron

Someone asked:  Does anyone know of a regulator which is both a step-up and step-down regulator?

That is called a SEPIC switching regulator.  There are a number of references to that on Linear

Tech web site.  I don't think that you'll find one at super low energy levels however.  -  But maybe?

Blogger

Very good Paul ... really appreciated, enjoyed and learned a lot from each of the courses you presented here on Digi-Key CEC

Thanks Paul for another good audio show

Iron

Pls forgive repeat question,

"Battery > 100 uF"?? slide 12"

 

Iron

Thanks Paul, very interesting set of sessions this week

Iron

Thanks very much for an Excellent week Paul!

Iron

Thanks, very usefull information

Thanks Paul. Anything about the "joule thief" circuits, based in germanium transistors ?

 

Iron

Best workshop week yet.  Really enjoyed the format (posting questions on forum rather than interrupting).  I appreciate all your effort.  Will listen to recordings intently for anything I missed.

 

Iron

Thanks Paul. Really liked the circuit examples and tips/things to watch out for.

Iron

Thanks Paul for the presentation. It was a good and informativ series.

Iron

Thaks paul  good info

Iron

Paul, the 5-day course was excellent.  I enjoyed your insight and the comments and ideas on live chat.

Iron

You saved the best lecture for last.

slide 19 - International System of Units - make your life much better by converting everything to MKS metric first and not mixing units or using the anything resembling BTU's, etc:

Iron

Awesome, Paul, thank you for the excellent series. 

Iron

Thanks - a very interesting series this week.

Iron

Thank you everyone, for a very excellent week!!

Available at Stanford U. bookstore.

Iron

This is critical to prevent thermal runaway of battery by adjusting the float voltage.

Iron

Never used either chip

Iron

The burst mode ripple is cutting off my audio intermittently.

Iron

IN  RE: SLide 15

one hates to dump shunted energy to ground .. given the class topic and power issue sensitivities today

Looks like we are ready to embed our smart phones with solar charging devices.

Iron

compact STEP UP TRANSFORMER ... Hmmm

"Battery > 100 uF"?? slide 12

Iron

I haven't used bq25504 but use another types like bq 2090

Iron

NO on the BQ25504 as well

Iron

It looks very familiar. We might have used it in one of our products.

Have not used but interested.

Iron

took a look at the bq25504 earlier this week from digikey

not this bq thing, either.

Iron

Today's next audience question is
Has anyone in the listening audience used the BQ25504 device?

Blogger

Does anyone know of a regulator which is both a step-up and step-down regulator? At one time I was doing a circuit using an ultra cap which decayed from 5V to 0. I wanted to output a constant 3.3V. during the entire decay curve, not just when it was above or below the output voltage.

 

substrate voltage generators tho are common on-chip designs

Message lost...No have not used

Iron

is it capacitor switched internally??

 

Never knew Seiko made semiconductors. 

 

Today's next audience question is
Has anyone in the listening audience used this ubiquitous S-882Z device?

Blogger

Not ha the pleasure of using the Seiko device.

 

Iron

not used it as of yet

Iron

R_DS doesnt look that good there

 

Que Viva Chihuahua! 

Iron

Future plan for monitoring.

Iron

@DougCook ... radio link as well??

Hello from Mexico, Chihuahua

Iron

Application: TEG powering valve.  No rectifier, but otherwise similar.

Iron

interesting point

Iron

This is exactly my application.  Listening intently.  Not creative enough to think beyond this.  Sorry.

Iron

well, the applications follow the topology picture ok.

Iron

Today's first audience question is
Does anyone listening have an application that does NOT resemble the topology shown in slide 3?

Blogger

Today audio is good and clear.

Iron

Hello from Milwaukee! Chrome is working for me.

Iron

audio is playing for me. I am using Firefox

Iron

Today I'm using chrome and audio not works...

Iron

Good afternoon, everyone

Iron

Hello from Toronto, ON

Iron

Hi all - Audio is live!

G'day all ... good class ... Paul N is a good teacher - good choice Anne R Thryft/Design News ...

Paul, would like to see ya write a series of a dozen or so articles and compile them into a neat little how-to booklet ... see if Design News will publish it for ya ... good experience at BBN and Lowell Tech and of course Orchid Tech

 

Paul wins the free tin foil hat (or Boston Baseball cap with little retractable antennae energy harvesting antenna to power all his personal app needs ...

Good morning from Redmond, WA! Cheers, Michael
