content: The first time I saw a pic of the counterwith the 5 on Twitter, I thought Daved had a little ooops.But the second thought was that the tube porobably wouldn't light up when put in in the wrong direction and this reversed tube was put in on purpose for a reason I don't knew.It looks like Dave want to be absolutly sure that the counter will never have an overrunThe counter looks really nice.What's missing now is an live-cam to show the couter.Its always nice to see solutions of different people from different professions to solve one task.I would have gone to the efford to cut out a small, tight fitting holes for every single tube.(And would have wasted many boards.)The solution Dave took is faster, easier, cleaner and looks really good.

content: Quote from: sagdahl on June 13, 2017, 04:58:42 amSort of agree. You have to try especially hard with the Russian tubes to not get an flipped 2 for a 5. When I built my clock I paid about twice as much for IN-8's as IN-14's, which are almost identical tubes apart from the 5 being proper on the IN-8. I think it was worth it.

content: Could someone help me to figure out the resistance value of the THT resistors he is using? They're going to the decimal points.From the video I guess it's either:red-red-black-red-brown22k @ 1%orbrown-red-black-red-red12k @ 2%But the problem is that I can't be sure which way to read the color bands.In the schematics video Dave mentioned something like 100k but that was just a shot from the hip, as I understood it. And I don't see these having that value.I've been inspired by Dave's technique, and have designed a PCB using this approach, which also includes the power supply on the board, but I'm unsure of which resistor value to use there.Thanks in advance to any help on this

content: Quote from: mov on June 13, 2017, 07:37:48 amThey're probably 22k. I've found this value is more common than 12k, and also I expect Dave deliberately soldered them to read left to right.You can always drop down to 12k if 22k doesn't work. Usually it's best to try the bigger resistor first anyway.

content: That is awesome, Dave!I've seen nixies used in frequency counters, clocks, even calculators (the Casio AS-L adding machine I have is proof of that... no picture, yet) but never in a live sub count.Let's see what EEVblog #1000 will bring...PS. I'm back...for now!

content: Hi, Dave,what happened to the counter project? It seems to be turned off on some of the recent videos.My guess is that the ESP8266 proven to be unreliable platform (both hardware and software), so it probably hung frequently for unknown reasons.I use ESP8266 in some of my projects, and I do hardware resets on it mercilessly and viciously, by wiring the reset pin to a timer. Of course, with the software and hardware designed to expect this to happen. That seems to be the only way to keep it running reliably for extended periods of time.I know that the ESP8266 has power consumption spikes that sometimes cause the hang due to a sag on the power bus, so I do have a sizable power reservoir cap next to it. Still, it would eventually hang even with a blinkie application if left running for several days or so.

content: Quote from: ludzinc on August 02, 2019, 03:50:34 amIts not going to "break" it though right? It will round to the nearest 100.Of course for some that will make the counter useless, but for Dave its not really going to matter.

content: You mean the arduino toolchain? oddFor future projects it may be worth using the WifiManager library, so if it is unable to connect to WiFi using saved credentials, it will open up a hotspot and let you enter in new SSID or credentials:Code:#include <WiFiManager.h> //https://github.com/tzapu/WiFiManagervoid setup() {...//Local intialization. Once its business is done, there is no need to keep it aroundWiFiManager wifiManager;//Tries to connect to last known settings//if it does not connect it starts an access point with the specified name//here "AutoConnectAP" with password "password"//and goes into a blocking loop awaiting configurationif (!wifiManager.autoConnect("AutoConnectAP", "password")) {Serial.println("failed to connect, we should reset as see if it connects");delay(3000);ESP.reset();delay(5000);}//if you get here you have connected to the WiFiSerial.println("connected...yeey :)");wifimanager:https://github.com/tzapu/WiFiManageryoutube counter link:https://github.com/witnessmenow/arduino-youtube-api
