ZMF Pro and Chrono GX chess clock physical characteristics compared 

Yes that true!

Thanks for chiming in!

Wow thats an amazing story! I have increasing became fmailiar with eletronics, and how to repair very simple things ( ru-vid.comenO20j1kLFM?si=NnuoOOaU7DKmj5MH ), and I even have a breadboard and follow simple tutorials for some basic eletronics you can see this post here: ru-vid.com/show-UCnk6Y2hk4Mg73tE-bLyxepgcommunity?lb=Ugkxo6hkVQY4JJVkiI4-d76269Dd7T1p0Q0B and I also have a second channel where do do automotive things and I tinker with simple repairs and using osocilliscopes www.youtube.com/@oneanddonediy Please like and share, a like goes a long way with the RU-vid algorithm! I hope to see your dad's prototypes or diagrams someday!!

Glad you enjoyed it! You are welcome!

You're welcome!

@@katzenpapa By the way, I purchased the ZMF. Thanks again.

@@EuphoricImpact glad the video helped! Congrats on your new purchase!

Glad it helps and thanks for the support!

They're good clocks but the chronos clocks have stood the test of time and they still are the best. I wish they still manufactured them.

What tab controls do you want to set your clock? I can make a short tutorial video for you. I can also make a PDF of the instructions so you can download them as well.

First of all I want to thank you. The time (s) are: blitz 3+2 and 1:30 for the whole game with a 30 seconds increment.

@@Grandcapi look it for the video shortly!

Agreed. I bought the Chronos clock a while back and its incredibly difficult to set correctly. I really hate that they make it so damn difficult.

I don't know if the display is fragile or not. I never hit it with anything. I would hope it's not too fragile but I assume it is quite rare to break a chess clock display.

​@@katzenpapait's the whole idea behind the zmart plastic clock. The display is hard to break. Special material

Never knew about that bug, I'll be on the lookout for that! Have you tried the DGT 2500 yet?

Looks good! I just don't like those as much as you have to flip it over to reset it

But that's probably good for some people who don't want to accidentally reset it

Yes when I first discovered there was mechanical switches on this clock it blew my mind as well, since I'm somewhat of a keyboard geek! The switch is soldered but can be easily removed if necessary. Actually in the older DGT clock there is mechanical switch, I showed this here in this video ru-vid.comenO20j1kLFM As for Chronos I assume they are running out of stock! Good luck on your search!

Have you ever used (or heard) a ZMF Tap n Set with buttons? I couldn't find video on RU-vid where you could hear it. It sure looks like the same kind of button with an underlying mechanical switch (not sure what kind) as a Chronos.

@@kleefan8 i have never used a tap and set (or heard) so i can't say. I might see if i can get my hands on one and test it out.

@@katzenpapa That would be cool if you were able to do that, but I understand it might not be possible. I was trying to decide between the Tap n Set button vs. the ZMF Fun II. The Fun II has a cool retro design with colorful LEDs but sensors instead of mechanical switches. I actually don't need a clock yet, but thought I'd get one during USCF Cyber sale at 30% off, to prepare for when I make a return to OTB play.

The Chronos GX (and maybe the samtimer/long body chronos) "may" be in stock again sometime in the summer. *may*. Both of my two longbody chronoses (sensor and push), with the latest programming they have, are currently at samtimer for repair (PCB ribbon pad printed flex cable issue to the LCD). The longbody chronos allows you to set delay and have the delay shown, if you are using delay, as well as the # of seconds at all times, and also allows you to set seconds (So for FIDE time controls with increment, you can give each player the bonus 30 seconds instantly--normally when you start someone's clock, they get the extra 30 seconds immediately). The GX however, does not allow you to set seconds in any time control longer than 99:59 minutes (1 hour and 39 minutes) directly, instead you have to quickly start the clock then immediately stop it, then you can edit the time and add 30 seconds (full seconds can be accessed here) to each player. (although you lose the milliseconds you took between the start and stopping of the clock, but at least that's available). The one thing the GX does have that the longbody does not, is ability to set both delay and increments in the same setting, so you can have mixed mode settings (this is very rare but has been used in the past). So except for that rarely used time control mixed feature, the longbody with current programming is FIDE legal as well as the GX (if you remember to set seconds quickly after starting the clock). The one serious issue with the longbody is the oxidation and wearing out of the pad printed cable that is soldered and then glued onto the PCB, which can make the digits fade, as they lose electrical current (this is not a problem with the LCD display itself). They can be fixed if you have the knowledge (apparently just a hot air gun or a hair dryer combined with pressure is good enough), I don't think the Chronos GX has this issue as it uses a JST style connector on the PCB.
