    Morphing Digital Clock

    Hello masoudmaddi,with my clock I encountered a similar problem when changing the daylight saving time.The clock accepts the change of timezone only when the Wifi-settings are also changed. So every time I change the DST I have to first type in some random wifi settings and save them. Then I change them back to my real wifi settings, changethe timezone and save this new settings again. After this the new timezone worksproperly. I hope this procedure will solve your problem too.

    Hello everyone.About a year ago I managed to built this clockI used a P5 panel and a Geekcreit ESP-F module from BanggoodIt still works fine.As everyone who saw it was fascinated by this clock I decided to built two other ones as presents.I still had two of the ESP-F modules left, so I only had to order two P5 panels.After I have assembled and programmend everything I have the problem, that the displaysare showing 4 lines, the next 4 lines are missing/blank, the next 4 lines are shown again and so on.The connection layout is the same as the one on the old panel and I connected the new panels the same way.I swaped the ESPs with my first clock and they work fine with the old panelThe ESP from my first clock shows the same error on the new displays.So I am sure that the displays are at fau...

Does someone have a solution for this problem?As super as this clock and this instructable are, there are so many different types of ESPs andpanels out there that it is difficult to find a working combination, especially as theneeded information (for example the chipset of the panel) are not provided by the shops and can change at each new order.A funny fact that I discovered by chance:When I touch the "EN" Pin of the ESP (I think I give a light eletrostatic discharge to it, which is not very recomendable)the clock sometimes starts working properly until the next reset.But most of the times it freezes or restartsby doing this. I can't reproduce this effect by pulling up or down the "EN" pin.

    Thank you for your support, shawvale, I've just made a quick breadboard built without the buttons and the switch and tried it. It works perfect now, without problems. I don't have the equipment for woodwork and as mentioned before I want a wall version. So from here on I'll have to part with your design. I'll post the result in the "Made it" section, but it can take a while to finish it.

    Hello Tobo, thank you for your advice, but I think this is exactly what I've tried.I've started the the configuration procedure with pressing reset on the ESP twice.I've connected to the access point 192.168.1.4 with my notebook (I've also tried my phone). On the web page I've chosen the tab "Configure wifi" and changed thetimezone from +2 to +1. After that I've clicked on save or just hit enter.The clock restarted but while booting it still showed timezone +2 instead of thenew setting, also after synchronization the time was still 1 hour off (still summertime).My next thought was if it is perhaps necessary to fill in the SSID and password of theWlan too, to change the timezone setting. So I've tried with the same SSID and password I had before, changed the timezone again and...

So I've tried with the same SSID and password I had before, changed the timezone again and saved the settings.Still the same.Then I've tried to change the timezone by reloading the code. I hoped to reset it to default. No result, timezone still +2.Next I've altered the line 40 in the NTPCLIENT.ccp from"char timezone[5] = "";" to"char timezone[5] = "+1";" also no result.I've also searched the web for a timeserver which distributes the DCF77 germantime with automatic summer-/wintertime. This would be the best solution as there would be no need to do this manually each time. I've found an old link to time.tr.fh-hannover.debut when I altered the NTPClient.ccp to this timeserver, the time display was blank.I don't know if there have to be additional settings or if the server doesn't exist any more.Perhaps someone knows such a server which distributes the DCF77 time instead of theUTC.Then I remembered an older post down below where someone with another problemsolved it by changing to another WLAN.I've changed the WLAN SSID and password, set the new timezone,saved it and afterthe restart the new timezone was finally accepted.SOLUTION:It seems that the timezone is changed only if SSID and password are changed too.I haven't tried if you can use some non existing fake ones to change the timezoneand then enter your normal one again, so that you don't have to reconfigure yourrouter every time.P.S. also my native language is not english and my grades at school were terrible.So don't bother and simply try your bestSuch forums have visitors from around the world and there are no complaints becausewe try to help each other and are happy if someone tries to help us. As long as we canfigure out what the other tries to explain there is really no problem. Otherwise just ask what was meant.

    Binary LED Marble Clock

    Hi shawvale,Thank you very much for your answer.The download link above is only for the .ino.There are no tabs with routines.Aren't these normally packed together with the .ino in one (zipped) folder? I'm really looking forward to built this clock. There are many binary clocks out therebut this one imho is the best. The binary theme combined with the oled display is great.Also the the temperature and humidity add on makes this clock stand out from the rest.The marbles as diffusors for the light are beautiful, although I'm looking for somethingbigger, as I want to built something to hang onto the wall. Some crystals maybe or the biggest marbles I can get .As my desk normally looks more like a workbench, a small desktop clock would beburied under my various projects most of the time.Than...

    Hi to everyone.Today the daylight saving time ended.I've startet the configuration with the reset button, changed the timezone and clicked on save.But after the reset it still shows the old timezone +2 instead of +1.I tried several times but had always the same problem.Right after the built there was no problem with setting wifi and timezone.I use a Geekcreit ESP-F Devkit V4. Has anyone an idea what could be wrong?

    Hi JohnBobo,just yesterday I built one with a P5 display from ebay.The pin layout of the connector was different from the one above and the connectorhad no pin "E". I made the connections like described in the link to PxMatrix. I didn'tconnect the pin D3 which was meant to go to pin "E" on the connector. As the clockuses 1/16 scan it seems not to be necessary. It worked on the first attempt. So good look with your built.Greetings

    My P5 display didn`t have a "E" pin on the connector, so I left the D3 pin on the ESP free.The clock worked on first attempt. As it uses 1/16 scan the pin "E" = 1/32 scan seems not tobe needed.
