I have been busy with other projects.
But I have a big list of ideas for more tutorials and App Inventor projects! As time becomes available (which should be soon!) I will be posting more items here.
I am also beginning to study the Internet of Things market and technologies. App Inventor may play a role in this exciting new technology where everything is potentially able to communicate with other objects and the Internet.

This web site is now receiving 25,000 unique visitors each month! I am very pleased that these tutorials are helpful to so many people all over the world!
Web site access is nearly the same every hour around the clock, implying a global readership (update: 145 countries!)
The web server output an average of about 800 kbytes per minute delivered to those viewing the web site. That is nearly 1 megabyte per minute.
I do not yet have a count of countries. I am working on that.
UPDATE: 145 countries!
The most common search is for information about App Inventor (duh!), followed by information about Bluetooth! High in the search list are also searches for information on Android or App Inventor and Arduino and searches related to App Inventor sensors (such as orientation sensor) and TinyDB.
When you visit any web site, your browser sends information about the operating system used, screen size, browser used, and so on, to the web site so the server can optionally deliver a web page customized to your configuration. When you search for something online, the search service (such as Google) passes the search text to the web server so web developers can optimize their content or learn what content is most desired by users.
The web server does not know who you are.
Spammers are starting to hit this web site pretty hard – registering fake accounts, attempting to post comment spam and more. I have just paid for a software plug-in that appears to prevent the fake accounts and comment spam.
I hope this does not impact the ability of readers to post their questions and comments and I will be checking on this over the next week to adjust settings, if needed. So far today, the plugin has successfully blocked 100% of the spammers.
With volume 4 done and rain in the forecast soon, I should have a moment to resume work on new tutorials and examples!
On 28 March 2016 you may have received a “Bandwidth Limit Exceeded” error message when trying to access appinventor.pevest.com.
This occurred because interest in tutorials on coding in MIT App Inventor is high! And the web server had exceeded the total bandwidth permitted for the month of March. I should have paid attention to the bandwidth logs and noticed sooner that I was closing in the bandwidth limit.
As soon as I learned about the problem, my Internet host (Tierpoint/webiness.com) responded very quickly to increase my bandwidth to six times more than it was previously. Hopefully this will hold us for a few months! It costs me a bit more but I want to ensure you have access to the current content and more to come!

P.S. Tierpoint/Webiness.com has been a great hosting provider for this and other web sites I have run for years, with excellent customer service. I am glad to put in a plug for them!
Each week the past 3 weeks I thought I was going to have time to put together some new tutorials and post them, but “stuff happens” and I have not had time. I have a great list of tutorial suggestions that have come from readers and I really want to work on them and get them posted!
Sorry for the long delay!
In other news, I have completed the writing of Volume 4 of my App Inventor tutorial guide books. The book is now undergoing proof reading and final formatting. I hope to have it available as both an e-book and as a printed book. I can now announce the title of the book “App Inventor: Graphics, Animation and Charts”. More details including a table of contents and sample pages as we get closer to release!
Short update – my web site at http://appinventor.pevest.com was linked directly to FB so that comments entered here, appeared there, and comments entered on the web site, appeared here on Facebook. All automatically.
However, that link is now broken. I was using a WordPress plugin to cross link the web site and FB page but last week, the makers of the plugin discontinued its use and the cross linking is no longer working. Hopefully I can find a new plugin to perform that function!
It was a nice to have feature as I could just check for updates on the web site without having to also check on FB. Oops! Now that this feature is gone, I will try to check the FB page more frequently.
Volume 4 of my App Inventor guides is nearing completion. I have to write one last demo program, the text for one chapter, proof read the entire text, and begin the publishing process. I will announce the book topic once I get the final chapter written (I prefer not to pre-announce until I know the availability). I can announce now that Volume 4 should be available in both print and e-book formats! Producing the print version adds a little delay to the final release but the final result should be very good.
UPDATE: Sales of the print version of Volume 4 are being discontinued as of October 18, 2016, due to rampant copyright theft. There are more used copies for sale than the total number of printed books actually sold. Based on sales, readers prefer the e-book version – therefore I am in process of discontinuing sales of the print version. The e-book continues to be available.
