Three years ago, I ceased my tracking of Florida karst sinkholes and the associated creation of sinkhole maps, because I found that my maps had been illegally posted on several Russian websites, regardless of the fact that I had copyright notices on the maps as well as the webpages that they were hosted from. I have now updated some imagery software that allows me to host the maps as full-size again. Thus, you will finding my full map selection here again as soon as I get the new format set across all of my maps. The first maps that will in this new format will be my Florida Karst Sinkholes Counties webpages

2025-04-28 - The recent rediscovery of the New Jersey Merci Train boxcar, documented in an article in Smithsonian Magazine from 2025-04-15, by Sarah Kuta has reminded me that I had photographed the New Hampshire Merci Train boxcar on 2019-09-29, at it's location on Reed Street, in Manchester, NH. I have started to introduce my photos of it on my webpage, The Merci Train, aka The Friendship Train, the New Hampshire Boxcar. There are only a fraction of my photographs online right now, but I hope to get moe of the prepared and added to the webpage. The webpage is an image carousel, which slowly changes between the photos, so the details can be appreciated. Please stop by frequently as I can only find little time snippets to work on the page further.
2023-07-18 - Most recently added to my website are a number of up-to-date news links and YouTube videos of the Faithway Drive Sinkhole reawakening, in Seffner, Florida.
Recently added are updates to my Machining webpage
Newly added to this website is a photo gallery of model railroading locomotives and cars that are either in my model railroading collection, have passed through my collection or are going to be sold on eBay. Currently, I only have HO-scale model railroad locomotives on these new gallery webpages, but I will be adding items from my other scales there as well. These pages will also have background information about the cars and locomotives, to aid those looking for information or images about those items.
My review of the SayoDevice Gaming/Macro Keyboards. I had purchased two of them from Amazon, a 3-key version and later, a 5-key version. They are awesome and hold up well to daily hard use. I have started to prepare a webpage reviewing these, along with a link to the website for downloading the software. I had a answer request from Amazon this weekend, about where to find the software to program these keyboards. By the time I had found the link that I had bookmarked on my computer, the Amazon question had timed out. So, I thought it would be a good idea to setup a webpage about these cool gaming keyboards.

I have just started a new category of product on my www.HistoryThroughPhotos.com website. At this point I only have one item listed, a Henry Ford 12¢ Postage Stamp Plate Block, 1968. But, now that I have a structure resolved, future pages for selling more plate blocks from my collection should be easier. The next item that will be listed there will be the Dag Hammarskjold misprinted plate block, with the yellow plate inverted.
I had purchased a pair of laser engravers, from China, that are similar to the pricey 'LaserPeckers'. Instead, the Internet scammer mailed me a toothbrush and is refusing to refund my money through PayPal. Even worse, PayPal will reward this scammer, if I am unable to show that I have documentation from a law enforcement agency indicating that they are pursuing this case of fraud. Worse still is that PayPal is still providing the shopping cart for this company!! Follow the webpage that I have created on my new webpage, So, you got trapped by an Online Scammer
I have just started a webpage discussing home automation and the Internet-of-Things (IoT). It will be covering home automation, primarily using the Alexa home assistants, with various other products, such as Smart Plugs, Smart Bulbs and cameras.
If a search engine brought you to this webpage, then any of the following subjects may be what you are specifically looking for, so you can just click on a button and skip over all of my babbling:
Or, you might be looking for one of the other websites that I host:
2020-10-25, the past week has been quite busy, so I only managed to tend to a few bad pieces of code and add a new sinkhole webpage, Florida Sinkhole Attractions. Sinkholes are not always a disaster, sometimes they can be enjoyed, like walking down into a tropical forest. I have also started the graphics for a map showing the latest Gainesville, FL sinkhole on NW 13th Place. That will be a map that you can zoom in on and pan around to see what is around that sinkhole. I hope to write the code for it Monday evening.
I created a new set of webpages on another of my websites, https://www.HistoryThroughPhotos.com for the sale of high-resolution scans of vintage topical postcards, from prior to 1923, thus being in the public domain. The most interesting early-1900 postcard scans currently available online are Vintage Halloween themed postcards.
My Android cellphone, tablets and accessories webpages received a major facelift this weekend. Stop by and see what my Android experiences have been, including what I have found to be my favorite Android Smartphones since 2010.
I just finished making a map of Belize, depicting The Great Blue Hole of Belize. This is the first page of three pages about it.
We went on a hike in Franconia, New Hampshire. We spent the afternoon hiking Coppermine Trail, to Bridal Veil Falls. Many photos were taken, some of the more interesting ones have been uploaded to a set of webpages at Hiking Coppermine Trail to Bridal Veil Falls. I used a image format that allows viewers to zoom and pan within the photos on these webpages. I hope everyone enjoys them.
And, I have started to invest more time into my earthquake map webpages, inspired after hearing about the earthquake that occurred on 2020-06-23, whose epicenter was located in the Oaxaca Mexican State region. I created a zoomable map that allows the viewer to zoom into the map to see more detail. This is the link to this Map of Mexico showing the earthquakes that have occurred over the previous 30 days.
In March 2020, I finally bit the bullet and purchased a 3D printer, model CZ-300, to be exact. I have started a webpage about it at the link in this paragraph. Right from the beginning, I encountered problems with assembly and setting it up for printing. The instructions provided with the unit leave LOTS to be desired. I will be expanding on this subject, to hopefully help others avoid the same issues that I have encountered. If you cannot wait for me to write something, then go ahead and email me.
