ESP-01 relay
So far only: Triggering of the relay for a certain time after pressing the button or with a LOW pulse on the switch_on pin. The relay switches to a pin relay. This is designed for the ESP-01, there I recommend not changing the pins. You can also use it for Arduino, then you can use other pins as well.
Vacuum tube Regenerative Receiver on 12VDC - 3v8hb.wordpress.com
This regenerative receiver works with a single 12AU7 tube or an ECC83. It is powered by low voltage 12 volts. The tube filament is also heated to 12v. With little component, this receiver has remarkable selectivity and sensitivity. the used coil found in a transistor AM receiver. The LF amplifier part consists of an integrated circuit of the LM386 type.
Open the gate by ringing
Free remote control via GSM A6 module This device answers the phone call, checks if the incoming number is stored in the whitelist (not yet on the SIM card, I'm working on it) and if so, the relay turns on for 1 second, then hangs up the incoming call. Because the call was not answered, there is no charge.
Oprava regulácie Sera air 550R
Po pár rokoch prestala regulácia tohoto výborného membránového čerpadla vzduchu pre akvárium fungovať. Buď išla naplno, alebo nijako 🙂. Nakreslil som schému a vymenil potenciometer. Ak chceš, pozri sem https://hobbyport.unisep.eu/sera-air-550r/
Ethernet LAN tester with LCD NOKIA 5110
A simple LAN internet connection tester. My idea was that after connecting the LAN, a test would run to read the IP address with a DCHP request. If the router does not assign an IP, I generate a very simple web page to verify that the tester is communicating. If the router assigns an IP address, the tester will try to connect to checkip.dyndns.com to get my external IP address. If it goes well, then the Internet works and of course the entire route of the LAN connection router - tester is OK.
