A Perspective On The B Type EESD - Robert Murray-Smith - Any issues?

Actually Brad, the JFET business is just an example of your irrational response to stress and your intellectual weakness.

Come now MH--do unto other's as you would have them do unto you.
If you dont like others dragging up your mistakes all the time,then dont drag up others mistakes all the time.

And on top of that you are never in a million years going to develop your own circuit around a JFET to get a Joule Thief that works at very low voltages.

Lol-really ?

On the other hand, making a technically and intellectually dishonest clip where you completely fail to measure the energy in a capacitor, fail to make a conversion to equivalent Lithium-Ion ampere-hours, and grossly exaggerate the amount of energy in your device is a serious issue.  Especially when you represent a company that is pitching higher energy density capacitors.

Holly snapping duck sh-t batman,call the hit squad.

If you can't make a distinction between the two then you have serious problems.

There is no difference MH
You made a mistake,and you hate others bringing it up time and time again.
RMS made a mistake,and your happy wollowing on about it almost a year later,much the same as you do in regards to EMJ and Wattsup not being able to answer your ideal coil question.

No, what i am saying is absolutely true.  I woke you up out of your electronics stupor.  For the last six years you have been building pulse motors and watching them spin and you weren't really progressing at all.  It was more or less stagnation, doing the same or similar things over and over and barely leaning anything new.

How many pulse motors have you built again MH?--or a JT even?
Could you throw up a pic of that electromagnet you built some time back now--i cant seem to find the picture--just so as we can see some of your !hands on! bench skills

The pen is indeed mightier than the bench.

Well i hope you put that pen to good use soon

I remember NASA spending a shit load of money developing a pen that would work in space,while the Russian's just decided to use a pencil

Oh come now Brad, there are probably about 500 errors that you have made that are akin to my "JFET error" so should we start that thread and start filling it up?

Lol-really ?

Yes really.  I think the chances of you designing a Joule Thief circuit that uses a JFET are very close to zero.

That's it, just be a mindless RMS drone and cheer him on when he does something that is so outrageous that a 12-year-old would recognize it as being completely wrong.  Be a good mindless drone and be inferior to a budding 12-year-old that is interested in electronics.  While you are at it why don't you send $6660 AUD to Hope Girl and buy yourself a QEG.

There is no difference MH

There is a difference, put your brain in gear.

Second time you mention that and I think it's a scrambled brains ricochet in your head.  I never showed a pic of an electromagnet.

You are selling yourself out and you are coward when you can't say that RMS did something seriously wrong.

But hey, perhaps we should not be surprised.   We have this clip from you:

"Triphene Super Cap 2600 Farads in half of a credit card."

https://www.youtube.com/watch?v=yvBckUkjEfM

Your claim is total bullshit Brad.  You caught the RMS disease.  You make a bullshit claim that you have made a 2600 Farad supercapacitor and it's not even remotely close to 2600 Farads.  You just "say it" and do no serious measurements on the device.  You are in the same morally bankrupt boat as RMS.  It was just a case of monkey-see-monkey-do.

Here, Brad, here is what I said to you on your YouTube channel 10 months ago:

Brad, supercapacitors are a fascinating subject and I looked at a few of Robert Murray-Smith's clips and I only looked at this only one clip of yours about supercaps.  I am going to discuss measurement issues, and I know that I am flying mostly blind here so I am asking you to be understanding because of that.

You are building caps so measurements are king here.  You put "2600 Farads" in your clip title, but in this clip you say you still haven't measured the actual capacity.  You need to be conservative by only claiming a capacitance value for what you have actually measured.

Just doing some preliminary paper napkin calculations that are not 100% legit and over simplified the numbers don't seem to add up.

1.7 volts at 2600 farads is 3757 Joules of energy stored in the cap. You talk about three minutes charging time in your clip.  3757 Joules over 180 seconds gives you an average of 20.9 watts to charge a 2600 farad cap to 1.7 volts in three minutes.  (I am really cheating here almost pretending the cap is like a resistor)

However, you say the cap is limited to 100 mA charging current.  If you have a voltage source of 1.7 volts supplying 100 mA that's 0.17 watts average charging power.  (Again, for a cap this does not truly make sense, it's just for illustrative purposes.)

I will put it this way:  If you have a discharged cap, and you set your power supply to 1.7 volts, and you measure 100 mA when the charging process starts, and it takes approximately 3 minutes to see the charging current drop to nearly zero telling you that the supercap is fully charged, then there is no way that your supercap is even close to 2600 farads.

Does this all make sense to you?  If the cap was truly 2600 farads you would have to be putting an average of 20 watts into the cap for three minutes to charge it, and your charging power starts at 0.17 watts and ends at nearly zero watts three minutes later.  So if I am more or less on track, then you can see there is a major problem.

And that suggests a challenge for you:  Develop a way to make a serious measurement of the capacitance of the supercapacitors you are making. You have to go beyond anecdotal "measurements" where you quote how long the supercap can run a motor.

I think it's great what you are doing, but you need to develop a serious measurement protocol that actually measures the capacitance properly.

You did not respond to my posting.  Your capacitor claim is just fantasy BSing.  You can do better than that.

Dear MH.

Might i suggest that you go and read my comments on RMS video's.
Once you have done that,then you may come back and apologise  for calling me a coward,because you think that i didnt have the guts to tell RMS that his measurements were in error.

Ah,so you have made the assumption  that i fully charged the cap.
Another outstanding job there MH-you should become a clairvoyant.
I mean hell-even i didnt know i had fully charged the cap for the video demo--your good MH
