The LED display cover is made out of white translucent acrylic sheets. Clock Module DS3231 $2.54 USD. :) Bitcoin or any altcoins. I built a simple API in Node.js that returns a JSON array which the ESP8266 can parse source-by-source. Here’s how I have everything set up inside the enclosure… Doesn’t tell you much, but the schematic above should explain all connections. Sign Up. Become a member to follow this project and never miss any updates, About Us Awesome idea! This project uses a simple ESP8266 WiFi microchip to poll financial data in real time — displaying prices on a MAX7219 LED matrix reminiscent of a digital stock ticker. :). Everything was sanded down with a rotary sander to ensure all edges/corners met up and to give the project a polished look. Maybe in the next version. Already have an account? Give Feedback Terms of Use Nice work, i got it working after 2 days:P hehe, I have a suggestion, it would be cool if you could add 2 led´s to the project! Blockchain, hardware wallets, tickers, miners, and all things cryptocurrency hardware and software. I got the idea from a friend who referenced /u/shesek1's project: bitcoin-ssid-ticker: Bitcoin price ticker over wifi SSID names. and last updated 3 years ago. Log In. I can't seem to reply to your later comment, but you're also going to have to find a way to convert the date/time if you switch to coinmarketcap.com, 'last_updated' looks like unix time. If you like current stock information, this is the project for you. However that requires mdk3/OpenWRT and a capable device that is quite a bit more expensive than the super tiny ESP8266. The device handle corresponding LED color changes as it scrolls through the sources and all of this data comes from the API. and 03/25/2017 at 11:08, x-lua - The ESP8266 is … It does not happen consistently, if i spam the reset button a few times it will usually work properly for a while. A community dedicated to Bitcoin, the currency of the Internet. We made a consumer-friendly device with lots of customization, enhancements and many APIs. For those who like the idea you can now get the TicrThing at https://www.ticrthing.com . created on 07/13/2016 Open, cheap, hacker friendly engine management, Setting up a new work space for electronics, metalworking, and the like, https://hackaday.io/project/28610-crypto-ticker, https://api.coinmarketcap.com/v1/ticker/bitcoin/?convert=EUR. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. 195.00 bytes - They have al the currency. Any ideas how to solve this? Project owner will be notified upon removal. The ESP8266 handles the WiFi connectivity We call it the TicrThing: your hands-free crypto companion. One red and one green. Hey, great little project! Do you mean you'd pay about 0.00729 for one? LCD Display ?? Create an account to leave a comment. This is a personal project of mine that I built mostly for fun, but I want to open source it in case anyone might find it useful. It runs fine on this hardware: http://i.imgur.com/HRebkwP.jpg, I'll let you know if I ever decide to do that _^. By utilizing Yahoo APIs and Arduino, you can create a stock ticker. UPDATE: Fixed by simply changing line 7 of init.lua to use sjson instead of cjson. Required fields are marked *. Hardware components: I will be maintaining the project here as I add more indices and customization features, as well as LED animations to represent price movements in especially volatile markets such as those backed by cryptocurrencies. The currency can be changed in httpget.lua. You can grab a ESP8266 in Arduino UNO compatible form for a few dollars/euros, put this software on it, power it using a phone charger and forget about it. https://api.coinmarketcap.com/v1/ticker/bitcoin/. BTW i connect to my cellphone hotspot at work:P getting addicted to btc. Or an ESP-01? Send message Hello, I really like your project and I think I have skills to help you. a member for this project? Looks like a nice product, you should probably consider accepting payment in cryptocurrency though, given your target market. Beginner Full instructions provided 1 hour 6,475. based on your interests. However that requires mdk3/OpenWRT and a capable device that is quite a bit more expensive than the super tiny ESP8266. Some Ruckus APs might run OpenWRT, you could use the original project where I got the idea from: https://github.com/shesek/bitcoin-ssid-ticker, Or get a super cheap ESP8266 for a few bucks ;-). hope i can get some more hours. Looks like you're using new Reddit on an old browser. However, unlike this project, ours is not yet open-source. So i wonder if it would be hard to implant ? Now i testing deep sleep for 5 minutes. Not really, what does your httpget.lua look like? The LED strip panel sits on a level above the ESP8266, the MAX7219 panels, and all of the wiring. So when the price goes up it will flash green or red if it goes down:P, I dont have the knowledge to implant this:(. Should be fairly simple, change the URL in line 1 and the 'rate' JSON source on line 9, "price_usd" is available directly, dunno about euros... edit: https://api.coinmarketcap.com/v1/ticker/bitcoin/?convert=EUR "price_eur", That easy, have changed currency before on the coinbase api, I will test with this one:P Thank you. My guess is that there was a change in the BTC price API. Log In. Is it an Arduino Uno-like board? Okay so I've come back to this project after a hiatus, looks like it will come to work but there's the intermittent error "PANIC: unprotected error in call to Lua API (httpget.lua:7: attempt to index global 'cjson' (a nil value))". We've been working on a battery-powered version of this concept for some time now. Learn More. The SSID ticker stopped working today. but arduino coded his esp! 1.09 kB - Hackaday API, By using our website and services, you expressly agree to the placement of our performance, I wanted to cover as much of this surface with LED strips as I could to make it as bright as possible, and I really learned a thing or two about soldering together LED strips. One outstanding issue with how this project is currently wired up is that the ESP8266 is being powered by a 5V power supply when it actually requires just 3.3V. I would pay $20-$40 for one. This always reports Bitcoin price in real time and also tracks major financial indices, representing futures data if the corresponding market is not open. We found Good Job, works really well but I have troubles using 8 panels. 07/13/2016 at 08:26, Plug the screen into the ESP - 3.3v, GND, SCL and SDA - pin numbers for SCL and SDA can be set in the code, Flash a recent build of NodeMCU with http, cjson, bit, u8g modules plus fonts, Set your wifi details, upload the code and enjoy. Code for this project can be found on my GitHub. Your email address will not be published. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. edit: I'm not actively developing this, I have an ESP/OLED on my desk running this but it does what I need for now... You are right about that. It would be more useful IMO to have it based on the last hour of data, if it's generally climbing or falling, but that would be a bit trickier. So i get about 7 1/2 hours runtime on one charge and update every minute, I have now modified the code with wifi setup, so first time you turn it on it will enter ap mode and you just connect and point it to your local wifi in a webpage:P And if it cant connect to AP then it goes back to AP mode so you can change wifi ssid. 8-channel (BBQ)-Thermometer hooked to your WLAN, The Arduino ECU / EMS Project. haha, Stationary and mobile, best of to worlds:P, PANIC: unprotected error in call to Lua API (httpget.lua:9: bad argument #2 to 'format' (number expected, got string)). Main Components: Arduino Nano 42 RMB. Press question mark to learn the rest of the keyboard shortcuts, bitcoin-ssid-ticker: Bitcoin price ticker over wifi SSID names, https://github.com/shesek/bitcoin-ssid-ticker. Code for this project can be found on my GitHub.. It would be fairly easy to implement between the current and new price but that'd mean it'll (potentially) change every minute. You should This project uses a simple ESP8266 WiFi microchip to poll financial data in real time — displaying prices on a MAX7219 LED matrix reminiscent of a digital stock ticker. You can grab a ESP8266 in Arduino UNO compatible form for a few dollars/euros, put this software on it, power it using a phone charger and forget about it. ESP8266-12 WiFi Module 12.5 RMB. Here is a crude drawing of how this is all wired up. Use the profit to buy more BTC =P. I got that error when i just put in the init.lua file, be sure you get all three files into the esp and reset. You can check out the video linked below to see how I did this. Do you have any idea what I've done wrong?
