I hope you don't mind but I've modified the sketch to work with a 1.3" SH1106 OLED display. I tried your sketch on a newer ESP32 the sleep timer still didn't work. So I replaced that with a simple delay set to 10 minutes and that works fine. Thanks again for the video and the project page.
Completed my first microcontroller using your guide, it was great help! Any chance you have insight into how I would be able to have it display various cryptos (changing every few seconds instead of only displaying BTC)?
That's great to hear! You would just need to query a different API to get the price for each of the other cryptocurrencies and then do a clear, and re-display routine with a time delay.
@@MichaelKlements how did u convert the image to fit in c++ i mean the bitcoin logo? and the code doesn't work now it says deserialiseJson error or something like that, it keeps repeating. Could u update it please?
Yes, the USB cable is just providing power to it. You can replace this with any USB power source or power bank. There are also pins on the PCB to power it directly from a battery or power supply. It doesn't need a computer to run. The code is available for you to download and edit so you could change or add anything you'd like. You could add multiple currencies to each if you'd like.
I haven't, but that would be really useful. I'll have a look at putting together something with a low power ESP32 module and e-paper display. This would be useful for a range of project dashboards.
@@MichaelKlements yeah, this has been my main focus of the last few days, im very new to programming so everything is a fun challenge... but certainly testing my patients
I've got a couple of upgrades on the way, so I'll have a look at putting a video together once they're installed, perhaps comparing before and after. Thanks for the suggestion.
@@MichaelKlements Thanks for the reply, and keep up the good work. Your great videos is keeping me educated with all your interesting content, as we are in lock down here in little New Zealand.
Hi Michael, first of all I like the overall concept of this project, it's absolutely awesome. I would also like to build such a live ticker for crypto, unfortunately I have a nodemcu 8266, wouldn't the program be almost the same? Best regards
That's a nice idea, it would definitely clear up some additional cabling. I'm using a K40 laser cutter with a couple of minor upgrades to get better quality cuts.
@@MichaelKlements I'm looking at the k40 now, any suggestions on the best cuts and etches? My printer should be here in a few weeks and I am about to pull the trigger on the omtech k40. Looks like I'll need a "chiller" either official or diy. What else?
The K40 works pretty well out of the box on acrylic, mdf and plywood. I'd say I cut 2-3mm acrylic and 3mm MDF most often. If you engrave MDF try masking it up first, you'll get much cleaner results. If you haven't already ordered the K40, try to get one with an ammeter on it (usually the cheaper ones). Mine has that digital panel and it's pretty useless to keep an eye on the actual current that the laser is producing. The ammeter helps you to protect your laser and get more consistent cutting results. I've landed up retrofitting an ammeter onto mine. You don't really need a chiller, just a bucket of water that you can throw some ice into every so often. I use some old soda bottles which I just fill with water, freeze and re-use.
You have to put a variable previously declared as Double and then in void loop "BTCUSDPrice.toDouble();". There are also a couple more modifications to the code but I don't remember.@@MichaelKlements
The code should work on this model too, you'll just need to select the correct board type when uploading. Obviously the PCB won't be compatible with the esp8266
Hey Michael, please build a air quality monitoring system with temperature humidity rain and wind speed measuring capability you may design a pcb and just do it in a simple way or you may design a case and put all the components in the case also, please tell us on how to change this code in such a way that it displays prices for more than one crypto at a time and shows the logo first and then the price
Hi Sid, I'll have a look at building a weather station with air quality monitoring as you've suggested. I've been wanting to build a small solar powered weather station for a while now. You'd just need to copy everything in the loop portion of the code and then edit the API retrieval to fetch the price for whatever other currency you're looking for. You'll also need to move the bitcoin logo display line into the loop rather than setup so that it's displayed on each update. You'd probably also want to reduce the sleep time between fetches so that it displays one currency for say 5 minutes and then the next for 5 minutes after that.
This is sick! But I was wondering, is it possible to write some sort of script or to program a Pi to display a web's REST API onto the monitor, almost like maybe a sub count or recieve any data from a web's REST API onto the screen?
If the data is available through an API then you should be able to modify the code to read the data and display pretty much anything on the OLED display.
They're back in stock again. I can make one up with the ETH logo on it but you'll need to do some work to find an exchange that has an unpaid API to get the pricing from.
@@MichaelKlements Actually I want less cause it's not fitting on the screen when there is 4 decimals or more :) Anyway thanks for Your reply I will look for a different price provider!!!
It will be very helpful and you will get more views if you upload a video on displaying more than one crypto in it (showing bitcoin price for 10seconds then Ethereum for next 10 seconds... like that)
Hello Michael, me and my dad are willing to make a crypto ticker too. But we don't have the expirience to build a pcb... We don't know where to begin. Is there a file link on the site for the pcb?🤔
There a link to a kit on my Etsy store that includes all of the components you'll need to build you own one. You also don't need to use a PCB, you can set it up on a breadboard if you'd like to.
@@MichaelKlements don't need no breadboard anymore... I have watched alot of your video's where you made pcb's for your projects. and from your video's i got the insperation to learn more and learned how to make pcb's. Best channel ever!😁
Thank you for this, just what I was looking for 👍 The one that I built works fine with one exception, it updates every minute. I'm not using exactly the same ESP32 that you used but it would appear to have the same spec. Any idea why this would happen? Regards, Alan.
The low power sleep mode library must not be compatible with your ESP32, so it's just ignoring the sleep line of the code. That's the only reason I can see.
What do you mean by glitches on the display? This could be a hardware or software problem. Quite a few people have built this same ticker, so it's unlikely that it is the code.
You do some great work. Well done. Rather than have most of the see through panel showing computer board hardware, is there a way to use a larger display and have that larger display take most of the space displaying the bitcoin price info?
"Hello bro, how are you? Thank you very much for your contributions. I want you to know that I have been following your projects closely and I really like them. However, I am currently working on a project myself and it would be great to have your help. I have a 3D-printed Bitcoin sign with LEDs, and I'm trying to connect the ESP32 to an API to fetch the Bitcoin price. The idea is that, based on the price changes, the SMD 5050 LEDs will change color and perform an animation. I have tried various methods, but I'm not good at using those APIs. I would greatly appreciate your assistance. If I need to upgrade my plan, it's not a problem. I just need to know if I can count on you.

$5 for 10 pcs and what was the shipping costs for that? $10, $15, $20 perhaps?
Great job! Love it!!!

Awesome! An idea is to make them inter-connectable (one power input and then daisy chain). What laser engraver/cutter are you using?

You could do the same with any Arduino compatible microprocessor (using this sketch) that has WiFi capabilities.
Michael the code doesn't work now!! it throws out some error can you please fix the code?

Is there a way to eliminate decimals?
Yes you could add a few lines to remove the characters after the decimal point in the code.
@@MichaelKlements You have no idea what a headache it was for me to find and be able to eliminate the decimals hahahahahaha
Did you manage to get it working though? I could potentially add a commented out option in the code to switch between decimals and no decimals.

Hey! Do you have an api for other cryptos? Because the one I found use HTTPS and is kinda difficult
Not a free one, most exchanges have an API available but they're usually behind a paywall.

That's the value available through the API, so depending on the API used you could get more decimal places.
