Kenapa Masih Memakai Camcorder di 2109?

Saya masih menggunakan camcorder atau handycam di beberapa kesempatan. Saya menggunakan Panasonic HC-W585. Kenapa? Bukannya sudah punya iPhone SE yang resolusinya sangat bagus?

Bagaimana dengan Canon EOS M6, kamera mirrorless yang super keren itu? Atau GoPro? Kenapa masih membutuhkan kamera lain?

Salah satu keunggulan yang saya andalkan dari camcorder ini adalah kapasitas baterai yang memungkinkan untuk merekam 2 hingga 3 jam nonstop tanpa perlu terhubung dengan stop kontak listrik melalui charger.

Independent LEDs Blinking

 using Arduino FreeRTOS, realtime multi tasking, :)

 I programmed LED on pin 2, 3, 4 and 13 to blink at its own time. The advantage of this Arduino FreeRTOS is we don't have to calculate the timing of each pin in respect of sequential execution. It's has its own task and schedule, independent of each other.

Old Mechanical Keyboard KPT-102 on iPad

Old Clicky Mechanical Keyboard on iPad, using Arduino as PS/2 to HID signal converter, :)

I use the code from https://gist.github.com/DorianRudolph/ca283dfdfd185bc812b7

But, as I use OSX, I can'n do this

"To make the programs work you need to open the file hardware/arduino/avr/cores/arduino/USBAPI.h located in your Arduino folder and make the Keyboard_::sendReport method public.
"

To do that I open the Finder, go to Applications Folder right click Arduino App, select Show Package Content and adit Keyboard.h at /Applications/Arduino.app/Contents/Java/libraries/Keyboard/src

Update: I tucked the Arduino  Pro Micro inside keyboard, :)

Upload Sketch of Arduino Pro Micro on Standart IDE

Yup, we could choose Leonardo to upload sketch to Arduino Pro Micro, without Sparkfun addOn.
