PFC design with Math Pad Intro with Blockpad Intro

[@lvstofly]

I've been binge watching older videos. Thanks for all the info. I got into learning electronics from working on cars. Then I looked into tubes, crystal radios, RF. My dad and family has been in the power line trade and when I was younger heard of a guy that died from static electricity from a line that wasn't finished. Seemed to dangerous for me so I went into carpentry. Now that I'm older, I'm fascinated and can't learn enough. I like how there are things that are still a mystery and haven't been figured out. Love your channel, leading edge world changing information in an easy to digest format! The white board rules. Thanks Eddie

Thanks so much for your feedback! Let me know if there's something that I can show;)

[@TrevorsBench]

Always thumbs up Eddie

[@KissAnalog]

Thanks so much!!

[@misterjorous]

Didn't know this tool. Thank you for introducing it to us. Looks like it is a very nice tool. If they got the Excel Developer mode or something like that, so I can add scroll menu, select boxes, increase values with bars and tables with build in values or equations to interact directly with charts, I totally buy this thing. Thank you for the vids, Ed.

[@KissAnalog]

You Bet! Thanks for your feedback! I'm glad that you can use it for free;)

Hi Eddie thank you for the Dope video, sooo cool, great info.

[@KissAnalog]

Thanks so much! I appreciate you!

Jeez, Eddie. I was just struggling to grok the equations "hidden" in an Excel spreadsheet when I saw this video. Being able to see the equations "work" makes them so much more understandable. Hopefully I can use the free version. $18/month seems a bit much if I need to use it only occasionally. One feature you didn't use is the built-in engineering units. You can write something like "I = 1 A, R = 1 ohm, E = I * R" and Blockpad will calculate E as "E = I * R = 1 V". Pretty cool. Thanks for cluing me in.

[@mikemike7001]

The units thing doesn't always work that well. At least some results that should be expressed in henries come out as Ω/Hz. At least some results that should be expressed in farads come out as 1/(Hz * Ω). Not cool, but also a reminder of how henries and farads are defined.

[@KissAnalog]

Thanks MikeMike! I probably should use the units or at least show this - thank you! Some equations get a bit dicy trying to get all the units in, so I just stopped doing it, but it does make for an easier read;)

[@mikemike7001]

@@KissAnalog Playing with Blockpad further, I discovered that it doesn't have many electrical units defined, and I did send them some feedback suggesting adding all the missing common ones. Meanwhile, I've been defining things like "mH = 1000 μH" and "μF = 0.000001 farad".

[@mikemike7001]

Since then, I've learned you can force Blockpad to display results in any of its built-in units by adding a "to" operator to the end of your equation. For example, when I got results in the awful "units" of "μH^0.5/farad^0.5", I added "to Ω" and got them in ohms. Not great, but doable. In the end, though, using units might be more trouble than it's worth. I haven't quite decided.

Hi Eddie. Blockpad looks really cool thanks for the introduction.just one thing. I'm not sure if it is just me but I find the magnifier on your cursor a bit distracting and actually making it a bit harder to see.

[@Gengh13]

For those of us watching on the phone the magnifier is really useful.

[@Kris_M]

Watching on PC, I too find it distracting, and at times it even blocks the view. Would having the magnifier use a fixed part of the screen work for phone viewing?

[@KissAnalog]

Thanks so much for this feedback! I appreciate you! I try to use the cursor in a way that when I apply the magnifier that it helps. I know when editing that sometimes I got it right and other times it is covering things up. I'll try not using it and see how that works. I'll zoom in more and see if that helps.

Blockpad looks like a very nice tool, but from what I can gather it is limited to 20 "equations" in the free version. I think most designs will exceed this limitation, The paid version is $18/month - almost $220 a year. If I were to use it professionally, I guess this is fine, but for hobby use, it's not going to kick Excel (which I already have) off the bench.

[@misterjorous]

18$/monthly??? Wow, that is a lot for what the tool seems to offer.

[@KissAnalog]

Thanks so much! I'm glad I can use it for free. I'm not sure what the paid version provides that I can't do with the free one;)

[@jstro-hobbytech]

I think it's cool for engineers doing a project. I write code to go along with projects usually. I'm still learning circuit based math. I learned quaternions as of late ones part for preparation for my hardest project yet I'm gathering info and hardware. It's gonna take me the whole winter.

[@KissAnalog]

It is great to hear you having fun doing this;)

[@john_hind]

Come on Blockpad, at least give us a WYSIWYG equation editor! This is the 21st century, we are not Neanderthals! Give me that and I'll even pay. Some HP calculators had WYSIWYG equation editors 30 years ago and that was implemented with four-bit microprocessors and a few kilobytes of memory!

[@KissAnalog]

Thanks for the feedback John! Have you tried this software? I actually think it is pretty good - especially the free version;)
