I built this myself from another random amazon kit. I just have 236 subs when this video comes out. I would like to thank everyone involved on this project and thank them immensely. Maybe one day my counter will go crazy through all the digits ! Thank you all again ! So fun and cheap, and worth having in the background while recording videos to keep seeing channel growth ! You have a lifetime sub ! Credit given in my video when it comes out tomorrow !

Hey, you're now at 952!! Keep going! 👍

[@EricTechstuffs]

@@IzzyOnTheMove Thank you !!!

[@birdseyeview1543]

Howdy Chad, Since the first Flitetest I was hooked, because you found the perfect formula: dual hosts, one seasoned, one novice. Your role here is played to perfection, but something is off, namely the characterization of the novice. Bit too sassy, disrespectful and little engagement in learning. Please understand good sir, i've been an ardent follower of yours and wrote for DR1. I also enjoy Rotor Riot which has become a great success. In short, with a few tweaks I believe you have another solid gem on your hands!

[@HackMakeMod]

Noted. Thank you for the feedback!

Wow, your editing is so amazing, and having an actual cameraman makes your videos seem so much more professional than other 8k sub channels. Excellent video, so surprised to find only 8 thousand subs on here! I'll sub 😊

Great tutorial but I’m finding that the site that makes coding easy isn’t working for me. I’m unable to add a site. I know Google APIs change more frequently than I change my socks so I’m not sure if it’s me or the world has evolved in the last year.

Loved the video. Will definitely be doing something like this with an ESP32 for my channel. Ill post a link once its complete. Thanks so much for the awesome content!!

[@OGRH]

This is really cool! Thank you for the beginners guide to soldering, too! Could y'all do a few videos of common things around the home that we could tear apart and mod around the home that are simple enough to keep our children interested, & get them learning, as well as get them into using these platforms for something productive? That list of reasons goes on and on but I would imagine you could not only get a lot more novice adult subscribers, but a lot of younger viewer demographics as well! A sub from me... let's start cracking open some quality time with the kiddos! Y'all would be rockstars if we could get some content like that!

[@HackMakeMod]

Excellent feedback! Do you have any suggestions on what types of household items to crack open?

[@OGRH]

@@HackMakeMod so I've got old hoverboards with 18650 batteries... people toss stuff out in the trash all the time... so even if people don't currently have the stuff for the builds that you present, maybe things people would, or could come across... like your clock is really cool... but how many people could really interact with your channel if they don't have a KZbin channel they wouldn't need to build a clock. And some of your other projects are amazing for entertainment, but you would get a lot more traffic if your viewers could interact with the channel. Not to mention all the links that you could put under your videos and get Amazon credits... this sky is the limit & your projects don't have to be too complicated at all... in fact, it would be better for the viewers since they would be participating. Just an idea. I am certainly not telling you what your channel should be. I'm just telling you as an average Joe what would have me coming back again and again, turning on that notification, and sharing with other parents...

[@programmingelectronics]

This is great!

[@BlueRidgeDave]

Got the kit earlier this week and got time today to solder them together.. Tested real quick before I had to leave and everything works.. I wonder if there are any ways to edit the code to add other things manually like put "KZbin" then it fades to the KZbin Channel Name.. thanks again for the kit.. I found it quicker to buy the kit than to order from Amazon separately since some of the items were not in stock. Now about that LARGE scrolling one.. I am interested in making that too.. any idea if you will release that on your website or make a video in the near future.. (soon i hope)

How can we add MM/DD/YYYY display to the code ? I see examples of code out there pulling from the NTPClient, but don't want to break Keith's code !

[@HackMakeMod]

I’ll look into it and get back to you!

[@HackMakeMod]

Here is the response from Keith… “You can simply add another “state” to the state object (ie date=7) and increase the state.count (which is the total number of states), then in the switch statement you can inject the date information when the state machine (function) runs.” Just save a separate file and experiment. Even if you break it, you can always go back to the original :)

[@EricTechstuffs]

@@HackMakeMod Awesome ! New to this programming language but found what Keith is talking about ! I also had to add another square to the 7819 and edited how many were connected and that allowed my full YT channel name to be displayed ! Powerful unit for the size and cost ! Many thanks for the help and fast reply !

[@BlueRidgeDave]

Just got around to building this. Your kit was PERFECT !! I will be dropping a video soon on my build. I think you will really like the case I put mine in. I do how ever have one question... Can you make the txt scroll for the channel name? My channel name is long "1620 Garage & Farm" and its cutting off half of it... Im sure its simple code tweak in the arduino. Just not sure where to make it.

[@H3FamilyVlogs]

Love it.. I've been wanting a subscriber counter for a long time. Looked at Lametric before and not only is it expensive they're also out of stock for who knows how long. I think I'm going to attempt this one. Now just to find a friend with a 3d printer.... Question though... does it show exact numbers or rounding. I'm hoping to have something that shows to the number count, but since youtube changed things a while back I'm finding most counters only count by 10's and then when you hit like 10k it counts by 100's

[@HackMakeMod]

The way ours is setup it counts by 10’s then 100’s after 10k. I’m pretty sure that’s a limitation of the KZbin API. Contact us through the store if you need a case printed, I might be able to help :)

[@H3FamilyVlogs]

Hello, great video, i have a question, i want to make a version with just 4 display units instead of 8, can you share de STL with me ? manny thnx

[@RudeboyMoto]

Me again, would it be possible to make the 3d files available for the full enclose not just the split model? I would like to make some small modifications to it in fusion 360, thanks.

[@EmbraceMaking]

Is this project still working? Trying to put together a "remixed" version with just 4 display units instead of 8 to be more compact. But beyond that it would seem that its not successfully connecting , getting "connection failed" in the serial monitor and also the fade time is way off. I left the default at 3 seconds but its more like 3 minutes. Just wondering if there are some updates required. Thanks!

[@brownlkt]

I would love to build the BIG ticker! Do you have instructions on that? Awesome video!

[@BlueRidgeDave]

same.. I just built the kit except for the case.. I would like to know if there is a way to scroll.. The larger one looks like it uses addressable LED strips.. I am interested in making the larger one as well.. HackMakeMod are you working on show us that larger one??? 😋

[@walkingdeadlands]

Bought this unit. Pretty cool. Question, it says 111,000 subscribers but I have 111,097 ? Is this normal ? 😊

[@HackMakeMod]

Normally to get more detailed stats on the KZbin counter, you need to select the “scroll“ option on the DoLibo website. But KZbin limits the sub counter to 10’s on channels over 9,999 and 100’s on channels over 99,999 subscribers.This is a limitation of the KZbin API. We don’t have any control over this. With that being said, we have been looking into other ways to scrape the info. Unfortunately we haven’t been able to find a way to gather this level of detail yet.

[@choppergirl]

HOLY SHI1T IS THIS A PHVCKING NIGHTMARE for a blind person. I got my Hayear 5mp inspection microscope fired up, pointing at soldering mat, with my TS100, flux, silver tip tinner, tip cleaner, sponge, SOS pad, and Kester solder. How the heck am I suppose to bridge these two modules together with the little bridge connector? How are you suppose to solder... under the plastic of the little included bridge connector? Using packing tape I taped the sides of the panels together to hold them in place. Whoever is the manufacturer could of designed them together so they just snap together and plug into each other. Looking at it closer, I think I'm just suppose to blob solder across the two pads using the bpard tiny lead to bridge the pads together, which makes sense. NOpe, I was on the wrong place on the circuit board. I didn't bridge a single thing. I probably screwed up something, who knows. Common guys... :-/ I think I'm suppose to bend a 90 degree angle in the tip of these pins with pliers needle nose pliers and come up through the through holes from underneath.

[@choppergirl]

Ok, I finished all of that nightmare, and mine is making all sorts of random strobscoping red dots Close Encounters flashing all around the displays... so I know I got 5v and ground wired up right... who knows if I bridged any of the other three lines. I can't tell with my inspection microscope. I checked my lines and they are connected to the right pin outs.

[@choppergirl]

I just got it to work. I had a short between 3v3 and D8 / CS !@#$%^^^ who would put a 3 volt pad right next to a control line... grrrr no wonder it was doing a Close Encounters light show. NOT BLIND FRIENDLY PROJECT even if you have all the tools. Only 10 soldering connections to make, but what a PITA because the industry makes things so small. And I do not have big hands. And I'm doing this under aninspection microscope.
