From my works in Greece, 2017...
#pirateradio #FM #DIY #electronic

Anybody wants to start broadcasting? This little device is suitable for:
-- Your squat, village, or neighborhood own pirate radio station.
-- Open event (demo, riot, festival, book fair etc.) coverage to let people know what is going on in the area. Yes, most smartphones and dumbphones HAVE FM radio option!
-- Solidarity broadcasts, for people inside camps, detainment centers, prisons etc. etc.
Do you want one? Talk to me.
Shown a metal spectacles case, repurposed to be a radio transmitter case.
Shown the side wall of the case with external power socket (12-35 V DC), Voltage regulator fastener, power switch switching between internal and external power. Description: The case works as common ground and radiator for voltage regulator. For storage and transport, the battery remains inside, disconnected, to avoid accidental powering on without the antenna.
Shown open case, with connected antenna and MP3 player. Description says: Normally, the case is closed when on air. Note the notch in the cover (left) for audio cable. Working on internal power (9V, 75% of maximum nominal voltage).
Left side shown from inside: 3-position power switch, 9V battery connector (internal power) L7812cv regulator and external power socked (12-35 V DC)
Inside case shown main transmitter unit (PCB) and 500mW RF FM amplifier PCB with actual amplifier visible as a tiny black dot.
Outside case shown BNC antenna output.
Shown simple wire half-dipole antenna, mounted on a side of a bookshelf.

1. I did this design for first responders, to be used in hypothermia treatment protocol (see the pic). All other uses are optional, but welcome.

2. Doybag or courier's sealed envelope.

Yes, it obviously depends on setting. "Automatic" gives you female version, formal/informal - male.

Nasze skromne laboratorium domowe
Tuż przed końcem 2022 roku umeblowaliśmy nasz #FlatLab, zajmujący połowę kawalerki, w której mieszkamy. Jak to dobrze, że oboje jesteśmy weń zaangażowani, bo inaczej szczęście małżeńskie mogłoby ucierpieć. ;-)
