Get best of the week

Cloud-based


Hello
In this post we want to talk a little bit about a couple of pet-projects, which involved our colleagues from Ulyanovska. With projects such situation often is as follows: a man sawing them quietly to themselves, showing only a couple of friends or colleagues and special publicity is not a matter
poluchaet.
Although often zasluzhivaet. from scrap materials, enthusiasm and desire to do something cool just because you can, from time to time make excellent shtukoviny. For example, children from hakspeysa Neuron once simply just for fun to make available 2G base station . it is clear that in the big cities (and areas), it is interesting only in terms of design and hobbies, but for developing countries, for example, it is quite a useful vesch. Firstly, it works, and secondly, the material component is very, very priyatna.
So,
about our

rebyat.

The team from Ulyanovsk from time to time experimenting with different things that make life easier in the office with white point zreniya. This gives them the opportunity to test a new technology hands on something real, rather than a spherical design in a vacuum,
and skills are not rasteryat.
Important
note: all the things described in the post so look, because it is specially used as much as possible cheap and available materials, and housing in general print the 3D-printer, which stands in ofise.

Cloudy ‌ Oscilloscope ‌

In the spring
of 2019, Mikhail Dronov and the guys realized that to live well and to live, when you close a compact oscilloscope, more luchshe.A some extraordinary tasks not required of him, it was simply to be, assist in solving simple problems and working to fill the measurement obtained in the cloud to easily share them with kollegami.
Heart
devaysa - Orange Pi Zero. housing made on a laser stanke. wooden, warm, nature- friendly.



In principle, even in a wooden performance, he looked quite sebe. But mark 2 it was decided to make the housing, printed on the 3D-printere. here it in A
(large GIFCA) . In a second embodiment, the body also decided not to stop and did tretiy. Here's what's inside dress makes handles on the ironing laser tehnologii. scheme and code oscilloscope GitLab.

Another
child Hackaton designed to help workers with access to office premises in Ulyanovske. Like many offices, there is a door to open which must constantly put-kartu. key The one key card, which decided to forget in the workplace or in other dzhinsah. Of course, the original problem here is that someone forgot the map, which should not be forgotten, but we all lyudi.I Therefore, this problem was solved in a simple manner - distracting counterpart on the right side of the door, he throws everything and walks you otkryvat. A distracting people from the work - not very pravilno. for all participants, in principle
protsessa.
So the guys came up and made a small system with the recognition of individual employees, which would open the door to them, even if they forgot klyuch. small
video camera instead of the eye provides a system vision The first prototype collected over vyhodnye. Hackathon organized a week later, which came more and more wanting, and therefore had time to do more useful, such as:





  • We launched a small computing infrastructure in the form of a service for recognizing photos of employees, an admin panel for downloading them, and a service for constantly processing video streams from door cameras.
  • ( , ).

It works the same on all Orange Pi with chamber (one per door kit). Stream is collected and processed on the PC in the office, which had been under rukoy. service video processing determines whether or not the camcorder with hope Rostelecom officer looks IT. If so, then the door otkryvaetsya. If not - here watchman will finish when the next Hackathon gather compact turret lethal vozdeystviya.
it should be
set at one door about 2500 rubles. The
first prototip. Up takes control wire button for opening the door




The new version of the
prototype is
going on all canons Hackathon - that was close from the available, the case and main poshlo. just as quickly assemble a working piece of iron, which is then when
you can be in every way to improve and ukrashat. in
face recognitionneed than CP office PC, both now and in the
GPU.
While in Ulyanovsk every seventh employee enters the office without klyucha. until Doorman lonely stuck on one door, in the sense of this, few veril. When they equipped three-door, something about a piece of iron stopped joking and started to use them
vserez.
