This is part of a quote from Philba that helped me a lot. “Look at logic MOSFETs. The IRL5x0 series can be driven directly from cmos logic. For example, the IRL520 is spec'd to 10A at 100V and costs less than $1. They cost a little more than the IRF series but are very easy to use.â€

I got a PIC18F4550 demo board last year but haven’t had time to use it. By the time I understand it and start to program, their compiler will expire so I haven’t installed it. What is left functional when it expires? I don’t want to spend hundreds of dollars to finish an experiment.

Keeping in mind that I was a disgruntled employee, put a picture of the boss on the door and just spit at it!

You can buy roller clutches at any bearing store and make something. You might consider a centrifugal clutch from a chainsaw or weed eater. It would disengage when the motor is off.

I was planning on the acrylic laying flat for the top surface when poured in the mold but the stuff I used was pretty thick so surface tension would cause the edges to curve up or down against the walls. You could make it wider and cut off the distorted sides or put a glass lid on the mold and fill ...

The actual name is "THE PROP BUILDER'S MOLDING & CASTING HANDBOOK" By James Thurston 792.025 My idea would be to use something smooth like Formica bent to the right radius and make walls for the right length of LCD to pour in Acrylic. If you make 1 long piece you can cut it up to make ...

Since the picture didn’t upload I will describe it. Flat on top, concave against the LCD to spread out the image lengthwise.

If there is an easy way to upload pictures, please let me know.

Maybe use lenses like in picture to expand the display and cover up the ends. If you figure out the radius, you could make a mold and cast all of them at once with clear acrylic and cut them into the widths you need.[img]

Lights shining in the water at night will attract bait fish, which will attract that Musky. One time I was using a flash light to check trim tabs. So many minnows swarmed around that I could not see the trim tabs. This is a good thing if you are fishing.

DirectX 8.1 has the samples AMCAP17.exe and VIDCAP. One of them works great. It puts each frame in a buffer that you can work with. If you haven’t used Microsoft DirectX, you are in for a lot of reading but it is worth it. I have mostly used the 3-D.

Re: programming

I recommend Sam's books. If they make "Teach yourself C# in 21 days", that is a good place to start. If there is a chapter “C review”, go there first. It will have the basics. C has evolved so much that you need to know a lot before you can do anything. Any computer book that starts with a...

Maybe "OR" your byte with a mask byte to see if the target bit is set.

Re: c# parallel port I/O

Do a search for inpout32. Jan Axelson has one for VB but there is another one for C++ and probably C#. It's free with samples for DOS. I use it in Windows and may have a sample if you need it.
