“Lavva kellä” – it means a “desk clock”.
My circuit Sculpture “Lavva kellä”. It is a small desk clock. All-seeing eye mean that its an internet-connected device (IoT). Once a day it synchronizes a clock with NTP time server.
There are two rows of shift registersand all numbers are individual 7-segment LEDs. Shift registers and 7-segment LEDs are connected simplified way, not in traditional way. The numbers are defined in the code as follows:
namespace numbers {
uint8_t tens[ALPHABET_SIZE][2] = {
{0b10001111, 0b00011111}, // 0_
{0b11101111, 0b11011111}, // 1_
{0b11001111, 0b00101111}, // 2_
{0b11001111, 0b10001111}, // 3_
