Re: Light Pollution

Beginning with the F series Judges, the boards have positions for the components. It is easier of course to install Sunlight Max when first building, since to retrofit means tearing up everything inside the Judge and rebuilding. Not just the main board, but all lane station boards. So I charge an ex...

Re: Light Pollution

Keep in mind that what looks black to the human eye does not necessarily look black in infrared light. Even if it did, placing the emitter or detector or both at the bottom of a deep hole is not going to help. If you are outdoors or under a skylight, or have a glass brick wall, the entire area and e...

Re: Microswitch - older Judge timer

I don't recommend micro switches, and supply only magnetic switches with my equipment. Micro switches are not hermetic allowing H2O and O2 to enter. Internally, the BeCu contacts start out bright orange, but slowly turn brown, then black and finally become unworkable for switching very low currents....

Re: Derby Magic Track

Re: USB to Serial Adapters

The shell is the same size, but the VGA has three rows of female contacts totaling 15, whereas the serial port has two rows of male contacts totaling 9. The VGA is known as a high density connector, the serial is standard density.

Re: USB to Serial Adapters

A serial interface on a PC is male, 9 pin. You might be looking at a different type of connector.
