RC Sailboat Tuning Stick

A while back I saw a gadget called a TrimmBlock that was used to tune the sails of an RC sailboat. Sadly, when I tried to buy one of these, they were no longer available for purchase. To me there was only one option, make one for myself using my 3D printer. RC sailboats...

Cheap Gas and Radiation

It seems to me that the choice is a simple one; do we want cheap gas and radiation or do we not. We have survived for seventy years with the threat of nuclear Armageddon. But our adversaries were mostly sane and had similar objectives to our own. Now we face an adversary who has...

Sailboat Building Tips

3D printing is a very capable method of producing custom parts for model RC boats. I use Autodesk Fusion 360 to design my parts and 3D print them using my Creality Ender Pro. I typically use Tough PLA filament for my parts. It’s easy to print and is generally tough enough for the type...

3D Printing

I got myself a 3D printer for a Christmas gilt. Well actually, my wife bought it as a gilt but I specified the type and where to buy it from. Before you get all hissy, she specifies her jewelry gifts for me to buy for her so it is a two-way street. The printer...

When it comes to matters of science there are no stupid questions; it’s the simple questions that reveal the most interesting findings. Here I want to...

Epidemics of polio were identified occurring in Europe in the late 19th century in the US in the early 20th century where it became one of...

John Kerry – Climate Czar

It seems that John Kerry, he of hanging chads fame, is to become Biden’s climate czar. I must admit that I had expected Al Gore to be the pick for this job but perhaps he is busy with other matters such as carbon futures trading. I assume that Kerry is well qualified for this...

How Quickly We Forget

The Friday morning before Thanksgiving week I jumped into the shower as usual and got cold shock; the water was at best tepid at its usual setting. I wondered if my wife had used up most of the hot water by surreptitiously doing a load of laundry or running the dishwasher before I got...
