KeymasterThat looks good. Sorry for the confusion with the resistors, I’ll make sure to correct it in the next version of the PCB. As said, it was to preserve backwards compatibility for using the LM317 instead of the better LM1117 . And backwards compatibility is a pain, nearly every time.

KeymasterThat is personal information that can’t be made public by default.
KeymasterThat’s an excellent solution, Robert; the tube connectors should have been one size bigger. Will keep this in mind for the next batch, I used the correct size for my prototypes, but the factory which helped me with production, mixed up the sizes (those are 5mm fuse holders, should have been 6mm).
KeymasterI also sent you by mail versions of the firmware configured for lower inverter frequency (down to 6.5KHz). Please test them and let me know if it helps.
KeymasterHi Curt,
Here is the diagram of v102 : http://www.pocketmagic.net/wp-content/uploads/2015/10/uRADMonitor_KIT1.1_sch.png
The IC1 is the 1117 regulator, the ADJ pin needs to be connected to GND, that goes through R7, so make sure you replace it with a wire.
The R13 must not be connected. On the v103, the naming of R7 and R13 is reversed, wish I didn’t do that.
The idea with these resistors is that instead of the LM1117, you could use the LM317, and the resistors were chosen to give out 3V. On a next revision (104), these will be removed completely.
KeymasterI’ve seen this before, and the problem was related to the inductor. Try getting 2.2mH inductors from a different source, or ,as a quick dirty hack, put two 2.2mH inductors of the kind you have now in parallel.
We might get over this by changing the frequency the inverter operates at – drop me a mail so I can send you a test firmware that uses a lower frequency (that might get noisy).
KeymasterHey guys! Thanks for the feedback. Next edition will have better silkprint for those resistors, I’ll also take care to improve the manual’s print quality .
KeymasterHello Robert, sorry about that picture, didn’t notice it. I’ll have it replaced when I get the chance.
While a Geiger tube is just a two electrodes discharge tube and there is electronic charge requirements in that regards, the polarity is still important because of optimisations made in the materials used: the cathode is a large surface material responsible of electron emissions, while the anode works as a charge collector and is usually a tiny wire.
For some tips on installation, please see the article for model A, the facts there apply to KIT1 as well, except that the KIT1 doesn’t have an enclosure: https://www.uradmonitor.com/tips-for-installing-the-uradmonitor-unit/
If you plan to use a BME280, you’ll need it to communicate with the air outside. Some holes (at the bottom) are needed. For POE you can use a passive one like:

KeymasterHi Waheed,
I was just thinking about your unit as I saw it offline, then I saw this post. Sorry to hear.
Last data is from 05/30/2016 @ 11:04pm (UTC) , and the readings are fine:
temperature: 32.5C
cpm: 10 / 16 / 26 (normal)
voltage on tube: 382V (normal)
duty: 36%Everything looks fine. It doesn’t look like a failure. Check the network cable, the power supply and try connecting the unit to a different router. See if the LEDS (green/yellow) flash. Try connecting to your unit directly, opening its DHCP given IP in your browser (in the same LAN).
Feel free to ask if you need help with any of the above.
KeymasterJust send me the coordinates you want it to show at (in decimal formal) and the city name. There will be a feature to change the coordinates yourselves, directly, but it is not yet ready.
KeymasterOk, I changed it, now should be right on spot.
KeymasterHello Ruben, those are some excellent pics, please post a few in this thread as they definitely have a chance for winning! Some guys already did a 3D printed case, I’m trying to bring them here as well, so people can actually benefit of the beauty of open source. Got your requirement on BME280, and it’s now on my list.
KeymasterThank you for this report.
I just fixed the issue and the names should be correctly encoded now.
KeymasterThat is correct, by default it uses Geo IP location, to make everything as close as possible to a plug and play system.
New coordinates in place! Let me know if ok.
Congrats on soldering your KIT1! Feel free to share pics or any feedback on your construction on: https://www.uradmonitor.com/topic/soldering-the-kit1/
KeymasterThanks Ziggy, yes we use the decimal format!
Coordinates changed, let me know if all is ok!
