Unboxing Tools and screws Assembled Boot Start printing Completed sculpture My own designs A ‘dgkim’ signed container (tested general overwrapping model) A flat container (tested size in millimeters) A piston for daily cleansing
Behind story I have been using APM since 2006. the first was Jennifer (for java). and Scouter (similar to jennifer x-view)
And the year 2020, I meet elastic apm (half setup). I finished the setup from Python django monitoring, to Vue RUM(with sourcemap).
In the year 2023, I tried Sentry for the first time. It seems new and is specialized for error tracking. I have set up for NestJS(backend), React(web frontend) and ReactNative.
Tested ESP8266 with RC522 NFC/RFID Reader RC522 is NFC/RFID reader, and it can be integrated into ESPHOME

Beelink Mini S I wasn’t satisfied by Pico PC so,
I bought another mini PC. the Beelink Mini S
Here are some specs.
CPU : Intel N95 Memory : 8GB SSD : 256GB Display Output : HDMI x 2 USB : USB-A x 4 Ethernet : 1 GbE x 1 Wifi : Wifi 5 Better than Pico PC
Silent : most important Pico PC doesn’t include PWM controlled FAN.
ESP8266 + IR Receiver + IR Transmitter When I was using raspberry pi, I bought a IR transceiver module for Arduino. and used it for several years. IR transceiver
And this year, I am interested in ESP8266, so I bought another IR receiver, IR transmitter.
Installed. Install esp8266 and voltage converter on breadboard.
Install IR receiver and IR transmitter in front of tv
