Re: Home Made Oscope

I have been doing some cleaning, and am thinking of unloading some NI-DAQ (data aquisition) hardware, can I post a "for sale" in this forum?

Moderators, please advise. Thanks.

Re: Wireless Internet Using Cordless Phone

Re: Green light!

The All red method would prevent the emergency traffic if the roadway was divided and the emergency vehicle could not get to the supposedly empty on coming lane. <p>What if the system gets hacked by collison shop owners, and they get it to go all Green? Anachry!
