Nobody have received something yet from simcockpit.nlWe've paid the orders and wait them for many months.So till I've receive it I won't advise anyboby to order something by simcockpit.nl, no garantees for delivery even if the website seems to be correct... :-(Let's seeTry cockpitsonic.de in english and I've receive my order quite quickly ... Redec is not yet in the shop but it's available by email request, no idea of the price ... BOB

Just to add to this... a couple other drawbacks to the usual mechanical rotary encoders are:1. You experience something called "chatter." Chattering is a common phenomenon in mechanical switches which repeats tim ON, OFF when the switch connects... like switch-bounce. If not corrected with a chatter prevention circuit, you will get false readings/malfunctions in your decoder, which brings up the second drawback.2. As mentioned, most mechanical rotary encoders (and optical rotary encoders) output a graycode. Gray-code is where the output only changes one-bit at a time. For example, let's look at a two-bit binary code. When counting up the code sequence goes like this: 00 (zero), 01 (one), 10 (two), 11 (three), 00 (zero) Notice that when going from one to two and three to zero both bits go from one to zero. Thus, more than only one single bit changed at the same time.Now, here is the same sequence, but in gray-code: 00 (zero), 01 (one), 11 (two), 10 (three), 00 (zero). Notice when going from one to two and three to zero only one bit changes at a time.The main purpose behind this is that switching noise in any circuit is intolerable, but not avoidable. Thus, you get more switching noise when two bits change at the same time. By using an output sequence that only switches one bit at a time (gray-code) you effectively reduce this noise.Gray-code poses a problem in that you have to decode it to indicate the shaft's position, or in this case the direction of travel (CW or CCW). As most of you know, these decoder circuits are costly. I have designed a simple circuit that will filter out the chatter and detect the direction of rotation. The simulations I have run indicates that it should work, but I have build a test version on a breadboard and see if it will really work properly. If it does, then it will have two outputs per encoder and one output will pulse when the direction is CW and the other when the direction is CCW. Since I am using EPIC, this is designed to work with that system. I am not familiar with FSBus, but I think it should interface with that too.If the test-build works successfully I will post the circuit design.

The 3-rotary decoder boards I just got made up had a raw parts cost of about $3, or about $1 per rotary.Richard
