ovo je zadnja verzija koju je rus napravio , 9 grama odašilje i analogni i digitalni signal i odlazi u stand by mode . baterija traje mjesec dana . jedino nekužim dali ima i zvučni alarm ?
ako ima onda je nenadjebivo jer bitno je da dođeš na 40 metara radijusa dalje zvuk radi svoje .
Starting today shipping new version beacon that combines features of two previous versions (VOX/no-mic) with added digital mode.
User can mix digital(packets) and analog(fading tones) modes, use only analog or only digital
Packets transmitted every second and received w/ special LCD that can read RSSI, beacon voltage as well main battery voltage monitor.
Packet is 4ms long and takes 100mA while transmitted, thus duty cycle is 4/1000= 1/250
then average mA is: 100/250=0.4
now given 300mAh cell we have 300/0.4= 750hours or 31.25 days !
One month operation, 9gram device (incl.battery)
In analog mode range is greater2-4times and operation is limited to 24-36hours (300mAh)
those without special RX can use the beacon usualblockingsignal path with body.
If you got digital RX you can mix the modes to get into near range using walkie-talkie then continue reading 200 counts RSSI.
When in mixed mode one can easili notice 1Hz clicking heard on walkie-talkie that indicates transmitted packet.
Will post video soon.
RF beacon v4 digital/analog with VOX and vario input
