Historically, the IV-22 tubes and DM160 tubes were never used together and the DM160 tubes are indeed more faint when compared to the IV-22 tubes. To get more light output you can try the following: - You can mount the 100K resistors R3 and R4 on the tube board in the "B" position. This increases the grid voltage to 5 V. Please note that this is in violation with the datasheet which mentions an absolute maximum value of 0 V for the grid voltage. I did try this with no apparent problems, so you can do this at your own risk. - You can also lower the values of the 3R3 resistors R1 and R2 (or even replace them with a short). This will increase the filament current and also increases the light output but may shorten the life of the tube. You can ask the customer service for a replacement IV-22 tube but these tubes come in a number of different colors, so it is important that you get a tube with more or less the same color as your existing tubes. If you go for the replacement, please send them a photo of your tubes so they can match colors. For the best results (considering esthetics) you can also consider buying a lot of 20-30 tubes on eBay and hand pick them for an as nice as possible display.

Hi, After building my clock and installing the software, everything works fine. Though installing took me a lot of trouble. But finally it works. But my problem is, that the DM160s are very faint. After building the clock, I've checked and adjusted all the voltages and resistances, as described in the assembly manual, but those two fillaments remain very faint, compared with the other tubes. They light up, bur not enough. What went wrong and/or what can I do? Second problem: the inside of 1 of the tubes is crooked, so the number is too oblique. Can I replace it? A problem may be the colors, I've read somewhere above.

You mean that it would be some kind of dongle to unlock the PC? I am sure that will be interesting for many people.

You are not giving a lot of info on what you are trying to do, how you are doing this and what is going wrong. This makes it rather difficult to help you. Did you install the Platino Boards package in the Arduino IDE? (As mentioned in the main project post above?) See f.i. https://github.com/ElektorLabs/Arduino

Hi Jerry, the code can be integrated into the firmware, but this means some changes. As we have support for the SDS011 this means the second uart trys to serve this one. Your code must run instead of the sds011 code on the system and this will requiere some sort of config to switch between those two. May at the end of the week it may become ready in a 1.3.5 or 1.4 firmware version. About the NRF, may some basic prepaerations can be done but dont extpect that for the next update to be complete in there Best Regards Mathias Claußen
