Predajnik na 13 kilometara, idealno za kosovske srbe

Low Cost Powerful AM Transmitter (13Km)

This is a simple AM Transmitter Circuit, but Its very powerful one. It can transmit SW range signals within 13Km circular area. Use external antenna for best results. I recommend to use 12V battery as the power supply. If you hope to using 12V AC-DC adapter you may want to keep very smooth DC out put using stabilizer, unless it will generate low frequency hum when listening to radio out put. Better to read following instructions before assembling the circuit.

> L1 Coil

Use 22SWG copper wire and make 10 turns, Insert a ferrite rod in to the coil. see figure 1.

>> L2 Coil
Use 22SWG Copper wire and make 10 turns. Don't use a ferrite rod. Coil diameter is 0.6 cm ( 1/4' ).
>> X-tal (Crystal)
Use 4.4333MHz crystal.

Alpine Linux rekapitulacija - veoma korisno - upotreba Docker na Alpine Linuxu

Супер корисна алатка за локално потписивање и печатирање ПДФ докумената:

nano radi.sh

docker run -d --name=signaturepdf -p 8080:80 -e SERVERNAME=localhost -e UPLOAD_MAX_FILESIZE=48M -e POST_MAX_SIZE=48M -e MAX_FILE_UPLOADS=401 -e PDF_STORAGE_PATH=/data -v ~/signaturepdf-data:/data signaturepdf

./radi.sh

Апликација за потписивање и печатирање ПДФ-ова у Докеру!

Ако неко ипак користи JWM, овај ексемел фајл му може добро доћи за уређење менија:
