Hello, here some updated info regarding transmitters
I have actually built 3 variants (they look all the same from outside
1. The first one is just as described above, powered with 5V from the USB
Distance to receiver module in my house: 50-75 meters (from outside of my house)
2. The second is as the first one but powered with 12V using a step-up regulator (5V->12V)
Distance to receiver module in my house: 100 meters (from outside of my house)
3. The third is the "monster". It uses another type of transmitter module (TX-SAWBOOST) from here http://www.soselectronic.com/?str=371&artnum=5732
It is also powered with the same step-up regulator (5V->12V). It can take up to 15V so if I change one resistor value in the step-up regulator circuit I could gain even more powerDistance to receiver module in my house: 200-250 meters (from outside of my house sitting inside my car!!!).
Maybe it's not legal anywhere but I did it just for testing purposes
The antennas are also from AUREL and they provide the virtual ground plane with the kit
I connect a receiver (as described before) and a transmitter to separate USB ports on the computer. I tried having a common USB hub for them but it only worked fine in my fastest computer (Quad processor) running Vista. In my old "HomeAutomation" PC running XP, I had to use dedicated ports. I do not know why it didn't work with the common USB hub
In the following posts I will show detailed pictures and a schematic of the step-up circuit I used
As I understand it this will control the nexa devices, replacing the tellstick
Yes, and if you have other types and matching pronto codes, those as well
How is it compared to it regarding range and so on?
Much better reach
