View Full Version : Electrist EE software for Palm OS
RedBinary
11-24-2004, 01:17 AM
Hello! Over the past 10 months I have been developing the Palm OS software entitled "Electrist" to help with Electrical and Electronic Engineering. During this time I have had the opportunity to interact with many Ham operators who have found use for this software.
After in-depth discussions with them I have incorporated several new features that may be of particular interest to those who frequent your site. Most notably in the 1.15 release I have:
* Updated the Electrist decibel calculations to calculate any parameter of dB power gain, dB voltage gain, dBu, dBm, dBW, dBuV, and dBV
* Added a VSWR calculator that can calculate any of VSWR, Forward Power, or Reflected Power given the other two parameters. It will calculate Effeciency and Return Loss for the system as well.
* Updated the Voltage Drop Calculation to allow choosing between AWG and Metric conductor sizes as well as the ability to create custom sizes based on cmils (Conversion factors are included in the contextual help built into the software)
In addition to those there are many many other calculations that can be performed, over 90 in all, including Ohm's/Watt's Laws, Inductance, Reactance, Resonant Frequency, Series/Parallel Resistance/Inductance/Capacitance, and Conductor Selection... with an interface that is far more advanced than any other.
More information can be found at http://www.redbinary.com/electrist_index.php
Thank you very much for your time and consideration!

You know, maybe I'm just a hard-ass, but I've got a real problem with poeple just coming in here trying to sell us junk. Also, why is it that the name and location given in the profile for this "user" doesn't match the callsign provided by the "user?" I was of the opinion that only bona fide, currently licensed amateur radio operators were given posting rights here. This guy looks pretty fraudulent to me!

Ray,
Aren't you a being a bit cynical here? I have a revelation for you: there are some great people in this world that aren't hams. Go figure.
I don't know Patrick (a.k.a. RedBinary) but he did announce a product that I though may be of interest to amateurs. I decided to pass the information on to our community. What harm is there in that?
How else do you choose to learn about new products?
I think you owe him an apology on face value alone.

Hey, Redbinary. #Is this software avialable only for that Palm thingy or is it available for other equipment like a PC. #Don't know any engineers (Power) that use their palm except to write on with a ball point. Then again, I come from the old slide rule group.

I didn't see any prices on the webpage that you are directed to but from the looks of it I think it would make an awesome Christmas gift for the ham who has everything.
Sounds cool to me. I'm assuming some or all of it is shareware? I personally wouldn't pay for it (would sit down and learn how to code for Palm OS myself before that!).
There was a ham somewhere who was writing logbook programs for Palm and some other ham-related stuff. I wish I could remember his callsign. I helped "beta test" it for him a couple years ago. It's good for portable use, like when going camping or maybe in the mobile. if anyone's interested I can try to track down the old emails.

Hello, Fred.
Well, since you bring this board to us thanks to the auspices of many paid advertisers, I'm a little surprised that you passed this along without collecting a fee.......for the advertisement.
I think Ray was right on the mark. #If the posting were from an amateur, who had at least purchased the product, or better yet a group that had evaluated it, then the posting would have been appropriate.
You recently removed the posting priveledge from some very competent and interested non-hams. #Making posting supposedly the exclusive priveledge of those of us who are licensed.
So, why are you now allowing someone who is not a ham to post? #Perhaps as a precondition of a paid advertisement.
I'd be interested in seeing an objective evaluation of the palm software (which was probably written on a PC and compiled for the Palm OS) if done by a club, or group, which was given the software just for that purpose. #To evaluate and write a consensus opinion of its utility and ease of use for amateurs.
Thanks for the priveledge of posting.

Fred,
I'm wondering if people are objecting to what appears a commercial for a product or if it is the fact that Patrick Griffin (self-proclaimed from the midwest) signed for an account using a 16 year old extra's call who was on the east coast.
Checking the details on Mr. Griffin, who according to the FCC database has no license of any type, now shows a Colorado callsign.
Fred, I think the question is just how forthright has Mr. Griffin been. I don't question that his product may have merit for ham radio operators, in fact I've downloaded it and will be trying it on my Palm.
I can see where some people may be upset over this. But I also wonder if there isn't some value to his post about the product. It isn't a great deal different if I would have written to hams about this neat product I found; except for the shameless self-promotion.
On the other hand I would hate to see this site bombarded with advertizements being thinly veiled as "product announcements." I suspect your paid advertizers would agree.
Just my $0.02

Well what is all this folderol? I went and looked up redbinary.com on networksolutions.com whois section. Well the infomation must be private. I wonder if he got his domain LOCKED. Which would mean if it is unlocked, a hacker could transfer that puppy, domain, to another registrar without his permission. Effective 11/14/2004 ICANN changed the policy on domain transfers. A domain name can be transferred without an acknowledgment.
For say a political web site you might want the domain information private but for somebody that is selling a $20.00 software package I don't thin so.

Well, I can always count on our users for a lively discussion.
In my capacity as the News Editor here at QRZ, I often get unsolicited announcements about new products. If I think that the product might have some interest to the community I will post it to the site. The development of new products and services is legitimate news, regardless of the fact that there is or may be a profit motive on behalf of the developer, and absolutely regardless of whether its progenitor is a ham.
Many, if not most of the best things in technology that we enjoy every day were created as a result of a profit motive. Profit is good and it brings great things into our lives.
Speaking of profit and using the subject product as an example, it is clear that a great many of our readers overestimate the size of the market. In my 10+ years of experience as an online retailer, I can say with fairly good conviction that Patrick Griffin is not standing to reap millions from the amateur radio public. Thousands would be a stretch. In fact, hundreds would be more like it. At $20 per copy, it's extremely difficult to get rich these days, especially when your market focus is as narrow as the Electrist. I would be absolutely astounded if Patrick sold 100 copies of the product to our readers, but for the sake of argument, let's say that he did and see where it takes us:
$20 times 100 copies = $2000 in gross sales
Replication costs, postage, packaging: $200
Gross profit: $1800
100 hours spent developing the software = $18 per hour
The admiration of the electronics enthusiast community: priceless.
So why are we beating up Patrick, and me, because he doesn't have a license, and because he has a commercial motive? He's offering a tool that has direct application and benefit to the members of our hobby. He correctly and logically identified us as a potential market for his product. Our hobby would be very different if commercial interests didn't solicit to us. How many homebrew IC-756 Pro III's do you think would exist? On a side note, I suppose that one could argue that we might just be better off if some equipment, like K1MAN's linears, had to be home built. At least there would be hope of some sort of massive failure. :-)
I suggested an apology from KU2S after seeing the words "junk" and "fraudulent" in his posting. Apparently, he wears the label "hard-ass" as a badge of honor. So be it, but I still don't think he has been very considerate. Can you imagine what it feels like to spend hundreds of hours learning how to program computers and then taking that experience to spend even more time to create a useful product, only to have someone suggest that your efforts have fraudulent intent? What's up with that, anyway? What a wonderful way to encourage the next generation's brain trust to dive into this hobby.
There has been an assertion that Patrick "borrowed" a callsign in order to make the posting. This didn't happen. Patrick registered as RedBinary and posted into the Incoming News section under that username. Each of our forums has different posting rules and not all require the level of "Ham Member" in order to post. The Incoming News forum definately does not require a callsign user ID to post. Why should it? All incoming news articles are screened by me prior to publication. I approve every article in this forum and my callsign is AA7BQ. Therefore, the "only hams can post" rule is both satisfied and made irrelevant at the same time. No, a ham may not have written it, but a ham definately did approve it.
There was also a suggestion that Mr. Griffen used the callsign of a 16 year old for some purpose. I have not been made aware of any such infraction, however, if anybody (i.e. NT7C) has any evidence that supports this then please send it to me via email (aa7bq@qrz.com) so that I can investigate further.
Finally, let's get a grip here. This was a simple product announcement posting, not unlike dozens of others that we routinely post. Most never get more than one or two comments (usually questions). I don't personally know Mr. Griffin, I've never used any of his products, and he's not a paid advertiser. I don't have a shred of pecuniary interest in his product or his business. This isn't to say that we wouldn't take his advertising money if he offered it, but it isn't a requirement for a news article.
I do suggest that if you are interested in his product that you try it out.

Oh joy, a political philosepher! Hi Hi. http://www.qrz.com/iB_html/non-cgi/emoticons/biggrin.gif
If someone were to make a habit out of submitting money-making schemes via QRZ, I'm sure that they would be prohibited from posting. A one-time post on an inexpensive ham-related software product, which as Fred points out was more of a labor of love than a serious attempt at getting rich, should not raise hackles.
I was unaware that non-hams could post to news, but Fred cleared up that point.
I think more of us ought to think of ways we can develop software or hardware tools that might be useful to our hobby, and let other hams in on it. I myself have considered doing some things, like kits. Whether for free or a nominal fee, it improves our hobby and encourages innovation.

In a private email with Patrick, he added the following:
Fred:
I just read all the posts regarding my software. Wow! There was sure quite a reponse for just one day, no? I'd like to take some time to respond in kind, if possible.
Oh, btw, you posted:
"$20 times 100 copies = $2000 in gross sales
Replication costs, postage, packaging: $200
Gross profit: $1800
100 hours spent developing the software = $18 per hour"
The math for 100 copies woulds actually be closer to:
$20 times 100 copies = $2000 in gross sales
Replication costs, postage, packaging: $0 (I only do online sales - no S/H)
Transaction fees for handling credit cards/vendor sites (avg 30%): $600
Gross profit: $1400 (Not accounting for one time development software and webhosting costs)
250 hours spent developing/marketing the software = $5.60 per hour
...of course I have sold just under 200 copies in 10 months so 100 in just a couple of days would be incredible!
> You know, maybe I'm just a hard-ass, but I've got a real problem with poeple just coming in here trying to sell us junk.
Patrick: I was not attempting to offend anyone! Honest! The way that I went about making my post was that I first emailed Fred and asked if he might be so kind to make a link. He replied by suggesting that I post to the incoming news forum, and I thought that sounded very nice - so I did.
> Also, why is it that the name and location given in the profile for this "user" doesn't match the callsign provided by the "user?" I was of the opinion that only bona fide, currently licensed amateur radio operators were given posting rights here. This guy looks pretty fraudulent to me!
Patrick: Actually I did not provide a callsign. As I stated in my post I am not personally a ham so I do not have one. If there is any callsign associated with my profile I have no clue how it came to be.
> Hey, Redbinary. Is this software avialable only for that Palm thingy or is it available for other equipment like a PC. Don't know any engineers (Power) that use their palm except to write on with a ball point. Then again, I come from the old slide rule group.
Patrick: Currently my software is only available for Palm OS devices. Soon it will be made available for Mac, Windows desktop and mobile platforms as well. (Thanks for asking!) And there are actually quite alot of engineers using the software - people (...and engineers ;P) in every one of the businesses listed on the RedBinary website are using my Electrist software as well as others who requested that their firms not be listed.
> I didn't see any prices on the webpage that you are directed to but from the looks of it I think it would make an awesome Christmas gift for the ham who has everything.
Patrick: It is $20 (Not listed on the 'product overview' page that I have in the post but rather llisted on the download/purchase page) and thank you! I think so too!
> Sounds cool to me. I'm assuming some or all of it is shareware?
Patrick: It is actually a form of trial software. Certain minor features are disabled, such as you can do Voltage Divider calculations but not Current Dividers; You can do dB but not dBm (Well, actually you CAN do dBm just by changing P1 to 1 mW... but you can't lock it in through the menu item...) but you can't do dBV, for instance. If you use it more than 10 times you have to delete it from your Palm and reinstall.
> I personally wouldn't pay for it (would sit down and learn how to code for Palm OS myself before that!).
Patrick: That is exactly how _I_ began Electrist and coding Palms to begin with! http://www.qrz.com/iB_html/non-cgi/emoticons/smile.gif
> There was a ham somewhere who was writing logbook programs for Palm and some other ham-related stuff. I wish I could remember his callsign. I helped "beta test" it for him a couple years ago. It's good for portable use, like when going camping or maybe in the mobile. if anyone's interested I can try to track down the old emails.
Patrick: There is actually TONS of ham-related Palm shareware and freeware. Googling will net you thousands of Palm/Ham related sites. The one I am personally most familiar with is http://www.qsl.net/va3pkh/palm-ham.html (My software is listed there too, but please don't yell at him about it. ;P)
> If the posting were from an amateur, who had at least purchased the product, or better yet a group that had evaluated it, then the posting would have been appropriate. ... I'd be interested in seeing an objective evaluation of the palm software (which was probably written on a PC and compiled for the Palm OS) if done by a club, or group, which was given the software just for that purpose. To evaluate and write a consensus opinion of its utility and ease of use for amateurs.
Patrick: I am not in the position to determine the appropriateness of my original post. I was invited to make the post so I did, and I was quite honored that Fred thought of it as News too!! I would also invite anyone to evaluate the software, too. It works in a trial state as I mentioned earlier. If someone from this board would care to try it out and write a full review here I would more than happy and pleased as punch to provide them with a free registration for a single Palm device. I would just ask that they go through Fred (if he would care to take on this responsibility) so that he can choose one reviewer and I do not get swamped with requests for free software when I wouldn't know who to choose to do the review.
> I'm wondering if people are objecting to what appears a commercial for a product or if it is the fact that Patrick Griffin (self-proclaimed from the midwest) signed for an account using a 16 year old extra's call who was on the east coast.
> Checking the details on Mr. Griffin, who according to the FCC database has no license of any type, now shows a Colorado callsign.
> Fred, I think the question is just how forthright has Mr. Griffin been.
Patrick: As I mention above - I did not enter _anything_ into the callsign field when I joining this board. As you state, and I stated in my original post, I am not a ham operator, I do not have a license of any kind. Through correspondance with hams and RF engineers who were using my software I added the features as outlined in my original post. Quite frankly I had never heard of VSWR until they requested that I add these calculations!
> I don't question that his product may have merit for ham radio operators, in fact I've downloaded it and will be trying it on my Palm.
Patrick: That makes you an excellent candidate to post a review! http://www.qrz.com/iB_html/non-cgi/emoticons/biggrin.gif As I said, I would be happy to provide a registration for this purpose.
> What I found was a person who apparently had "borrowed" a callsign for the purposes of posting in this forum. Now, does that not seem a bit alarming? Does this not appear a bit fraudulent?
Patrick: Please see above - I didn't mean to appear to try to cloak my identity. If I were I wouldn't have stated that I was not a ham in my original post.
> I went and looked up redbinary.com on networksolutions.com whois section. Well the infomation must be private. I wonder if he got his domain LOCKED ... For say a political web site you might want the domain information private but for somebody that is selling a $20.00 software package I don't thin so
Patrick: WOW! Good thing I'm not running office! I have no idea about my domain name being "LOCKED". I have no idea about the new ICANN policy that is mentioned. All I know is "I am not a crook!" In researching this I also looked up redbinary.com on the network solutions whois. I see "Lock ACTIVE" towards the bottom of the page. I haven't looked into this yet to find out exactly what it means. What I did do was to go to the whois page for the registrar for my domain name (tucows, not network solutions...) On the tucows whois page (http://resellers.tucows.com/whois) is the following text:
"With the new shared registration system model, the nature of the WHOIS server has changed. Traditionally, the InterNIC maintained the WHOIS server for .com, .net and .org domain names, and a single query returned full whois data including registrant, administrative contact, billing contact, technical contact, and nameserver information. Under the new system, the registry WHOIS simply contains information on which Registrar is authoritative for a given domain. Click here for details."
I beleive this explains why my contact details do not come up under the network solutions whois. If you perform the whois lookup with the domains registrar (http://resellers.tucows.com/whois) you will see:

*** I changed hosting services from homepageuniverse to hardhathosting and did not add the email alias for support@redbinary.com because support@anydomain generates TONS of spam. I have not updated the contact info because A) I didn't even think of it and B) homepageuniverse.com is extremely graphically bloated, takes for-freekin-ever to load up/login on my old dial-up set-up, and I have nothing but extremely bad experiences with the guy and his services - so I go there only in times of dire crisis.

So anyhow, I'm sorry for any confusion or ill-will that I may have caused. I was indeed just trying to get the word out about my software and, due to my correspondance with the hams who suggested the additions to the decibel calculations and the inclusion of VSWR calculations, I contacted QRZ.com because I thought it might be a place where there might be some interest (for exactly the reasons I stated in the original post). I would like to sincerely thank Fred for allowing me the opportunity to do this, too!

For whatever is worth in the name of the amateur community I apologize to Patrick, it is really sad that the right to speak our mid can affect the way we express our selves and with this said I don’t think that Raymond is wrong in speaking his mind but to be wise to know when and about what is really the important thing, this is related to attitude. It is this type of attitude that will eventually kill our hobby. Just remember that attitude is a little thing that makes a big difference.
Now in advance if this post is troublesome or offends some one please accept an apology.

Partrick,
I am from the "slip-stick" world, three of them , but I embraced the HP-15 and then the HP-48SX when they became available. I bought the first PALM because it has a serial port. I could now do computations and run my equipment with a handheld unit.
I bought your software and will let you know how I like it.
Thanks for writing a program some of us can, and will use and thanks to Fred for posting your product.

I purchased Griff's software after reading this post and downloading the trial version. The software is "EXCELENT" and the author is a very friendly, knowledgeale gentleman. When I completed my software purchase transaction, I received a personal, not computer generated form letter, email from Griff. In fact we exchanged several emails (we are both from the midwest).
Once again the software appears to be of a very professional quality, has a very easy and intuitive interface and from my limited review appears to be accurate.
Thanks Fred for allowing Griff's post. I for one would appreciate seeing additional entrepenuers with products of value to the Ham community being allowed to post here.

Fred:
I think that had you posted this topic under your "Announcements and New Products" thread, you probably woudn't have drawn the flack which you have.
No hard feelings, Patrick, but there are many who have small businesses based on a single product or two or three that are of interest to hams. #So, why haven't they been posted here? #Rightfully, they should be posted over on the other thread. #Quite a few have been.
Your product is probably a helpful tool, just as are other products being offered to us hams for a price would be.
The bottom line is that this is your operation, Fred, and we are just user/commenters. #But, the question remains as to why you did choose to post Patrick's information here instead of on the other thread.
Perhaps the answer for you is a very small listing fee for a single product advertiser as Patrick is.

I purchased this program last July or August.This program is great. I have used it for home and work; ( I work for a small, Airplane Co. here in the Seattle Area.).
There have been many updates and improvements to the program. Updating and support has been very good. I am still hoping that Horse Power calculations will be eventually added to the power section, other than that, this program is a Swiss Army Knife of calculator programs for the Palm. I give it 5 stars. and yes it is a try before buy situation. I think it is a good thing that it gets exposure on this message board. After all it is a try before you buy thing. 73's Martin

Concise Model 380 Radio Computer (http://www.lise.jp/sliderules/concise/g_380.html)
I bought one a year or two ago, and it was actually much more convenient to use than a calculator while preparing for the Extra exam. You can also find slide rules for electronics on ebay, many times never opened, brand new, 30+ year old stock. Kind of neat!
