Egg Time (VR game)

brand2Virtual Reality for consumer use is here with release of Oculus Rift, HTC Vive and other headsets.
It’s a new media type where new ideas and concepts can be presented to the user.

Is my first atempt to create a VR game, currently in ALPHA stage where the basic functionality is tested.
The game revolves around simple mechanics and physics.

Game was released for free on Steam [download]

So I bought the HTC Vive

viveSome time ago (around August 2014) I got the Oculus DK2 , and I was one of the backers of the DK1.
I had ordered my rift in March 2016, and I am still waiting for it to arrive.

Long story short, the HTC Vive came first to my shop so I bought it since I can’t wait to get my hands on some good VR.
This article is some sort of summary of my vive use experience.

Radex ONE geiger counter

rad
There is a new, cheap and practical geiger counter on the market, it’s Radex ONE from Quartarad.com.
The Radex ONE uses SBM-20 GM tube, which is very sensitive and can detect beta, gamma and xray radiation.
You can display 3 different values on the display : uSv/h , dose in uSv and CPM.
It has sound alarm which is adjustable from 0,10 to 1,00 uSv/h and also vibration alarm.
It can measure from 0-999uSv/h . which is enough for day to day use in the environment.

Unit is powered only by single AAA battery, and due to good engineering, the unit can stay ON for 6 days straight until the battery is depleted.
There is also possibility to connect the unit to PC via USB.
It can send data to the computer and with the software from Quartarad you can save graphs, change settings of the unit and upgrade the firmware.

Here is a video review of the unit.

If you want to upload the data to radmon.org,

Nokia 3310 Geiger Counter

nokia_geiger

So I found an old Nokia 3310 in trash at work, seems like a waste so I took it home and re-purposed it 🙂

I thought that I can put in to the chassis some of the displays that I use for arduino projects but I found out that the 3310 display can be used with arduino and the implementation is very easy due to the fact that the display has metallic pins.
After connecting the display with arduino I started to wonder what else can be done.
So one thing led to another and thus the Nokia Geiger Counter was born, if you are interested in schematics please click read more.

Geiger Counter + Gamma spectrum analyzer under 10€

999-20005P1The title of the post says it all.
But it might be very hard to imagine to build such complicated instrument with budget under 10€ but it’s possible, kind of.

I came across a circuit scheme that seemed easy to build but it was intended to be used with 8Bit A/D converter (original article).
This converter is used with parallel (LPT) port which can’t be found on modern computers.
Also the 8Bit converter offers only poor resolution of 256 levels of energy and it is hard to calibrate.

The original cuircuit consists of 3 sections, Detector, Converter & power supply.
And I decided to make it alot more accurate and a lot more easy to build.
