Quoted from Nixpaints:Apparently bench testing without having a game to test in is not %100 accurate
Quoted from Pin_Guy:Depends how its bench checked, did they happened to send you a breakdown of the tests performed?
I am glad that somebody else was thinking what I was thinking. Every opto board I have built and sent out passes on my bench and nobody has mentioned any problems when received. Testing equipment is important!
Quoted from pins4u:Isn't it FANTASTIC that we actually have several options these days.
Quoted from pins4u:These days we have several options for this board and most are superior to the originals.
100% agree. Choice is good for the consumer. It also means that the consumer should do more research on what's available and weigh up the pros and cons of each solution. Of course, that's not required. Just like getting a second quote with a different contractor or a second opinion from another medical professional. It's 100% up to the buyer how much effort they want to put into their purchase.
Quoted from Pin_Guy:I think DumbAss can provide a very high quality board at a lower price.
If the OP (or anybody else) is interested I have two versions of the board available. The original Williams circuit (with ICs in sockets) or a re-designed circuit with discrete transistors and LED indicators for the transmitter/receiver pair.
