Sometimes it really does work out.

Upgrading the operating system is always taking a chance. It is a lot like jacking up the whole house, replacing the foundation under it and hoping everything works out. I upgraded my Ubuntu from version 12. something to 14.04 and everything was wonderful until I attempted to run

Processes and Projects.

Tonight’s post is a shift in direction. (Only momentary for those of you that want me to get back into the electronics… we will return.) I have been very busy the last month setting up a hydroponics garden. This is the first of a series talking about using the process of gardening to lead me

More Testing Work on the Homemade Box and Pan Brake

Gap between the hinged board at 90 degrees and the base board with no metal.

Another step forward with the brake project. I cannot say the light at the end of the tunnel is very bright yet, but I am pretty sure it is not a train. I am a whole lot more hopeful

Debugging the Homemade Box and Pan Brake.

The stiffening bar on the back f the hinged piece

In the last Post “Test 2 of The Box and Pan Brake – Making Progress” I said I was making progress. I am beginning to feel right now I am not although I think I am. Most blogs and D.I.Y. articles do not post

Test 2 of The Box and Pan Brake – Making Progress

Using Deep C clamps to clamp the clamping board

In the last post about the brake “The Second Baby-Step with the Box and Pan Brake , the problem I had was the clamping board slipped backward when I bent the metal. This gave me a very rounded corner. To fix that problem I purchased

The Incredible Shrinking Drawing and a Good Website.

Tonight’s post will be very short, but it actually will be about two subjects. First I am embedding a new video I have created about CAD. Second, I am going to recommend a web site about electrical and electronics theory.

Some co-workers told me about the website All About Circuits. The site is very well

Experimenting and working around problems in LibreCAD

It has been a little while since I have posted anything and especially a long time since I posted anything about CAD. I helped a viewer with some CAD problems and decided it might be helpful to others. This new video was posted tonight.

Testing Testing Testing … Smoke ’em if you got ’em.

The component side of the Thermistor Board.

Sooner or later there comes a time… a time when you just got to plug it in and find out if it is going to work. Hence my title “Smoke ’em if you got ’em”. Success, no smoke came out. However,there has been more than one problem.

Encapsulating the problem… Waterproofing the solder joints.

Coatings I tried to use to insulate the solder joints.

Almost everything in design is a compromise. Even something as simple as insulating wire connections that may be exposed to water. It always comes back to: “What are you trying to accomplish”, and even then often there are compromises. In the case of the

Electrical Noise

An unshielded twisted pair.

Noise is a hassle in just about everything and in electronics and electrical circuits it is no less of a concern. However, it is something we can handle with some planning and if that fails a little knowledge will get us a long way to figure out a “work around”
