RGB night lamp based on Arduino

2 years, 9 months ago


Probably, everyone in the childhood had a dream (and not one). It is possible to try even to remember that feeling which overflows soul of the child at execution of his dream or that far familiar gloss in eyes … I in the childhood dreamed to have the night lamp.

Now I study on the 4th course BGUIR and when we were told that the academic year project on circuit engineering can be made not on paper, and on a piece of iron, dawned on me: the night lamp which was so wished in the childhood can be made most. And to make not just object which will light the room in a night-time, and the device what can be managed with ease under any mood. And why is also not present? I decided to add a feature to change colors by means of hands: the closer the hand is brought to a night lamp, the one of colors (RGB) burns more brightly. And also it would be desirable to manage a night lamp by means of a remote control panel.

Digital microwave from mechanical

2 years, 9 months ago


Many of us have dachas: someone raises potato, someone does repair, and someone — both. But, undoubtedly, all pull down any stuff there (and suddenly it is useful!). Everything is a part of this raggletaggle stuff: from different rags to thermonuclear reactors of broken-down household appliances. A story about how by means of Arduino Nano and a heap of free time the microwave oven was recovered, it is possible to find under a cat (many photo).

Just USB stick

2 years, 9 months ago
Hello, Giktayms!
Today I want to tell about how I happened to dress the naked USB stick in not absolutely normal camouflage, namely — in an old lighter.
Certainly, I have not enough experience in it and on a knee with improvised materials of quality special wow to achieve complicated, however I after all had an any unique artifact which frames from creation history with some comments I expose on court of the public.


There is such imperceptible masking. If it is interesting, welcome under kat.

As we made analog of Oculus Rift

2 years, 9 months ago
2015 was pretty rough in respect of events and announcements of devices of virtual and augmented reality from large producers, such as Oculus Rift, HTC Vive, Sony of PS4, Microsoft Holo Lens, etc.
Expecting rough interest in this area, at the end of 2014 me it was decided to begin to investigate this direction.
As a result, within a year to us, small command without external support and financing, one of the first succeeded to develop a solution which allows to start applications and games for Oculus Rift DK2 together with the latests version of Oculus Runtime.



But at first we will talk a little about sad things …

VRD + Leap Motion = augmented reality

2 years, 9 months ago
Earlier I already provided to you the overview of a prototype of a helmet of VRD.
That time Leap Motion quickly bored me when using on the normal computer.

In this article I want to share the impressions of use of Leap Motion jointly with a helmet of virtual reality of VRD:


The controller of gestures was installed on a helmet, Oculus Rift VR and here is similar that from this turned out …

Коптер в рюкзаке (часть 2) — Лего для дронов

2 years, 9 months ago
Всем привет. В этой статье я бы хотел рассказать подробнее про конструкцию моей складной рамы.

Напомню, что главной целью была компактность дрона. На мой взгляд, существуют два наиболее важных требования к дизайну:

• Шасси рамы должно быть съемным

• Лапы (лучи) должны складываться друг над другом для максимальной экономии пространства

Вдобавок я постарался дополнительно реализовать следующие идеи:

• Модульная конструкция рамы

• Виброизоляция модуля для электроники

Теперь обо всём по порядку.
