Соревнование для радиолюбителей — 7400 contest 2012
Пришло время расчехлить паяльники! Cнова начался конкурс разработок на логических микросхемах 7400-серии (а также 4000 CMOS и советских аналогах — К155 и иже с ними). Срок приема работ — до 31 октября 2012 года.
Суть очень простая — нужно придумать и реализовать в железе что угодно на логических микросхемах: можно на breadboard, можно на печатной плате, можно клубком проводов — как угодно. Нельзя лишь в симуляторе работы сдавать. Призов целая куча [1], поэтому с пустыми руками уйти будет сложно.
Что делать?
Ограничений нет никаких, но чем оригинальнее и неожиданнее — тем выше будет результат. Не обязательно делать что-то на сотнях микросхем, выиграть можно на очень простых, но оригинальных схемах.
Для информации, вот что победило в прошлом году:
1: 7400 Capacitive Touch Array [2]
2: 7400-based Capacitance Meter [3]

- Illogical Dickson Doubler [9]
- 74Clock [10]
- 7400 Series Drum Machine [11] (Four-channel, sixteen-step percussion synthesizer/sequencer)
- Electronic Realization of Etch-A-Sketch Toy with 32-Page Flip-Pad [12]
4:
