Hello
I also have problem with noise peaks when i try write TEA5767 via i2c. I also need data from RF level updated continously so i must every few second write and read to have actual RF level - unfortunetly it causing noise peaks . now i try second PCB design and still the same problem. if...
antenna design for long range 13.56 mhz +tool
hi
one project - many solutions :)
i building sports timing system for my friends - they ride a mountain bike.
my idea :
i want to measure time between the start and the finish points. Each biker has a unique chip which is registered on the start...
125khz long range rfid antenna design
hi
i want to build this system in a few days - when i do it and test it i send info about it :)
i think uhf RFID it's very good choice.
very thanks "rautio" for idea !

long range reader for sport timing
yes
869 MHz in Europe it's good choice for me.
i found chips form MARIN EM4222
**broken link removed**
i looking now for reader project i can't see any info about type modulation etc...
maybe someone had experience with this chips ?

rfid sports timing circuit
hi
thanks for this - very intersting.
i have a few question: 900 MHZ rfid it's only a active tag or also passive ? (most important for me is passiwe tag)
time of reaction - i must have very fast time of reaction
collision - it would be the best if this transponders...
long range rfid schematic
Hi i looking for project , ideas for long range passive rfid 125 khz - long range = about 100 cm.
I want to read word tag unique with manchester encoding.
any ideas ?
i found some information on internet - i buy oem reader but all time range is too small
thanks
Robert
manchester encoding
hi
i am a newbie in microcontroller - now i am building long range RFID receiver 125 khz unique.
i am good in RF systems (radio transmitters etc.) but microontrollers - unfortunetly not :(
i am learn avr microcontrollers with bascom (atmega8)
i am looking for idea code in...
