400 V DC/DC Converter with a Choke
Since the transformer used currently in the converter block may be problematic in terms of availability and construction, I have decided to design a compatible converter using a choke.
New detector prototype
Some time ago, an idea emerged to design an alternative detector for Radioactive@Home project. Current design caused some problems sometimes, so I decided to challenge the problem and come up with my own solution. Unfortunately I was busy with my day job so the work was a step by step on the evenings. Currently the prototype is at he stage where it can be plugged in for the project, so it is a high time to publish schematics and some info.
ACTA
With regard to the ACTA (so-called Anti-Counterfeiting Trade Agreement) accepted by European Union, we feel obliged to warn you that our website may be unavailable in some countries soon.
ACTA Agreement was initiated by organizations describing themselves as "defending artists from bad pirates" and has been enforced on EU in secret negotiations initiated by US Government. Non government
organizations from all over the world agreed on condemning both the way of negotiations ware taken and allowing by this agreement cutting off websites "uncomfortable" for governments of countries that
signed ACTA, without proving infringements of any laws.
How to join to project?
Because of a large number of questions emailed to us, we decided to write a short article in form of a FAQ.
Second detector release
The collection for Radioactive@Home detectors
As we announced earlier, we start second presale of Radioactive@Home detectors.
This time however the detector will be in enclosure, but it is still a "kit" so it will require assembly. The detector will be sent as a PCB wit case and Geiger tube. You will have to buy USB A->B cable (such as for a printer). The date of shipment - January 2012
Attention:
All that contacted us regarding group sale are requested not to order the detectors through main site.
Group orders will be realised by contacting through PM on the project forum!!!
