I won't connect my dishwasher to your stupid cloud

I won't connect my dishwasher to your stupid cloud

This weekend I had to buy a new dishwasher because our old GE died.

I bought a Bosch 500 series because that's what Consumer Reports recommended, and more importantly, I could find one in stock.

After my dad and I got it installed, I went to run a rinse cycle, only to find that that, along with features like delayed start and eco mode, require an app.

Марсоход управляемый ИК-пультом

Машинка Марсоход это возможно был самый первый проект на нашем сайте, 15 лет назад. К сожалению, тот проект довольно трудно повторить в настоящее время. Например, где взять два одинаковых шаговых двигателя от пятидюймовых жестких дисков? Это целая проблема. Но ведь идея-то проекта была интересная?

Попробуем реализовать его на новом уровне. Для этого, напечатаем разработанное нами шасси нового Марсохода на 3D принтере и соберём его, как написано вот здесь. Получится вот такая машинка, как на рисунке выше. 3D модели всех деталей есть на нашем гитхабе.

В качестве платы управления возьмем нашу плату MA3128. Я думаю, что этот же проект можно будет так же...

A USB interface to the "Mother of All Demos" keyset

https://invidious.privacyredirect.com/watch?v=DpshKBKt_os

In the early 1960s, Douglas Engelbart started investigating how computers could augment human intelligence: "If, in your office, you as an intellectual worker were supplied with a computer display backed up by a computer that was alive for you all day and was instantly responsive to every action you had, how much value could you derive from that?" Engelbart developed many features of modern computing that we now take for granted: the mouse,1 hypertext, shared documents, windows, and a graphical user interface. At the 1968 Joint Computer Conference, Engelbart demonstrated these innovations in a groundbreaking presentation, now known as "The Mother of All Demos."

Любительское электровакуумное дело. Освоение стекла от крупных ЛДС Т12

Домашние стеклодувные забавы сегодня осложнены добычей недорогих и легкоплавких заготовок-стеклотрубок. Остатки линейных ламп дневного света (ЛДС) разных типоразмеров могут служить их бросовым источником, но повозиться придётся. Главное дело — вдумчивое и аккуратное потрошение заводских ламп — придётся работать с токсичными веществами. Заготовим такое стекло, попробуем применить трубки от крупных ЛДС типоразмера Т12 Ø 37 мм и Т8 Ø 26 мм, собрав из них простую самодельную лампу-индикатор. Читать дальше →
