    Question about having RJ45 cable outdoors

    Hello Is it ok to expose some parts of the cable outdoor? I want to connect to a network at my neighbor's house but I dont want to use wireless. So I plan to just use an ordinary RJ45 cable to connect my pc to my friend's router. Is that ok? Thanks!

    Looking for a schematic of a prepaid water meter

    prepaid water meter Thanks for the replies! I think its going to be more tedious if I build the electronic meter myself because I'll just be making a prototype of a electronic water meter system much like the electric meter systems. I already looked at websites that sell/market these such as...

    Help me understand two configurations of ECG circuit

    hello! Attached are two circuit configuration that are similar except that one uses a single supply voltage and some capacitor and resistor values. Can someone explain what the right leg drive do? How does the OP97 accomplish this? Will there be a difference between the two circuit configuration...
