for display text , analog clock and digital clock

The board was created on the basis of a project by a famous Russian blogger.

Current features are:network time and date synchronizationautomatic and manual brightness adjustmentcontrol of 12 LEDs WS2812control via web interfaceAdditional information and firmware updates: https://vk.com/@retromodding-chasy-na-lampah-in-14-s-wifi (Russian)

The most important part of a computer architecture is a clock circuit. This circuit has the option to run freely in a-stable mode and also operate in single step debugging mode.

This PCB is part of the capacitive kitchen timer project featured on my blog. It contains the microcontroller that listens for capacitive inputs and then reacts to them. The MAX7219 seven-segment controller makes sure that the MCU can display the current time on the two seven-segment displays.If you'd like to build this project, make sure to also order the following two PCBs as all three are required for building this project:7805-based power supplyCapacitive touch ring (TBD)

As some of you probably saw in the description of my profile, I used to work years ago as a HW design Engineer for a multinational company and later I moved to Papua New Guinea. I've been working as a radio and maintenance Engineer there helping some aid organizations the development of the 3rd world countries. This month I returned from my exotic journey around the world and I thought of publishing the plans of this clock to celebrate this transition. I hope that the entire exercise of posting these schematics will help me overcome the reverse culture shock in a smoother way.

I would like to present to the public the project of my watches on VLI. The IV-6 indicators are used to indicate the time, and the IV-1 is used for the dividing point. To obtain -40 volts DC and ~ 4 volts AC, a converter based on the KF1211EU1 microcircuit, power switches IRF7313 is used. The transformer has one primary winding with a midpoint, two secondary windings with a midpoint. In the primary winding 2 x 6 turns, in the secondary 2 x 50 turns and 2 x 4 turns, the material of the ferrite ring is N87, dimensions 10x6x4. To control the grids and segments of the indicators, the “bottom” BC857 keys in the SOT323 package are used. Real-time microcircuit - DS3231 in SO-16 package, microcontroller - Atmega328P in TQFP32 package. Installation is performed on two double-sided boards, boards are connected by a board-to-board connector. Also, under the indicators, an optional installation of SK6805 addressable LEDs is provided. The device operates on any 5 volt power supply unit that has a USB connector.For the firmware of the microcontroller, the corresponding contacts are displayed. You can use Atmega88, Atmega168, Atmega328, the firmware takes about 8kb without LED backlighting. The firmware is written in C (avr-gcc), the code is available on GitHubWhen ordering, you need to choose a thickness of 1mm or 1.2mm and a panel from pcbway. !!!The circuit uses a rare microcircuit KF1211EU1 (made in Russia)!!!

Searching for Christmas PCB will only leave you looking at endless results of Christmas trees with led's in different fashion but wait....... Look at my design of a unique and useful Christmas Clock which is an actual functioning hour clock with 12 led's and a buzzer for every hourly alert. Its Beautiful and suits the purpose of a Christmas decoration as well as suits it's purpose as a clock.The following design is made under the idea of creating a unique Christmas decorative board which will suit a purpose as an electronic gadget too. This can be used as a creative Christmas wall art as well as a clock .In this case ,I have designed a Board with "Rein deer" theme :):):)MERRY CHRISTMAS FOLKS :):)
