EE ToolKit PRO for iPad

This is slightly different than I thought it was going to be. I’m a retired radio tech, who recently discovered “Mr. Carlson’s Lab” on youtube/Patreon. It’s fun to dust off the knowledge, although I won’t be teching...just a fan now. One of the first things I did was to go the rectifier section and go to full-wave bridge. I used the first values, and got a real surprise that the load resistor would have fried like bacon! So manipulating its value by an order of magnitude brought a satisfying result. Very handy for pinout references, etc. Actually better than I expected.

I had an older version, lost after a "master reset" and I do not have any qualms about shelling out some more money for this very practical and well maintened product.

This is a great app and one of the few I pay for. Its excellent for anyone doing basic circuit design and testing. I have it open pretty much all the time in my lab for one thing or another. Things are well laid out and very intuitive. The device lists are of limited value and centred around TI stuff but thats only an observation and not a complaint. Made a recent suggestion concerning transistor voltage indications which was well received and hopefully it will show up in the next edition. I'd give it full marks now but I'd really like to see that useful improvement.

I have been using this app for a while, as a reference when I'm working on electronic hobby projects and also as a visual tool when I'm teaching my son the basics of electronics. It is great for both purposes. Don't get me wrong, I also read datasheets and research/read a lot on internet but it is very convenient to have this app on the iPad right on the bench for that quick reference/function. Now, the best part: Tom, the developer, has put real effort on this app and he stays on top of his game. You may find an issue here or there, as I did, but when I wrote him about it, he immediately replied to my email, answered my questions and continued to follow up with several emails. Now, that is what I call great customer service and a developer that cares. You won't be disappointed with this app!

This app is beyond my expectations. It is really a pleasure to use and work with. I consider this is one of the best app of its kind. Thanks a lot!

Well done. It helps me a lot. Really useful app.

This app has so many useful features that I wonder if I would ever need or want another electronics app. Everything is easy to find, and intuitive to use. There are calculators for almost anything you can think of in here, and they don't just spit out the answer, they show the formulas too, which is nice. The reference materials have saved me time hunting around online, and another feature I especially like is the comprehensive simulator for the 555 timer IC. Support is first class here - I emailed the author and got a response back in just a few hours. For all the reasons above, I highly recommend you grab this app.

I use this app on my iPhone for long time. Now - on iPad where screen is so much larger. Some info is missing between two types of this software, but it is a small thing which can be fix later. Thank you for such handy tool!

This app is a gem. Bought it speculatively and it's chock full of features, that the screenshots and description don't really give it credit for. The 555 worksheet and simulator is really cool, the Ui is easy to use especially for resistor color codes. The IC databse is very extensive especially in the 7400 series. There is a a very convenient link to everything's datasheet at TI. Every single link works. This product should be 4 times the price. Very well written.

Just getting back into the hobby and this is just a fantastic reference to keep handy both with the iPod version and this IPAD version. Lots of useful info and the eye candy is pleasing. JD
