That's not really a great deal.
You've been able to get a 4.2" Nextion touchscreen for years for under $70. (~60 Euros)
I used the OLED screen from amazon - Link to Product But a lcd monitor should be even easier to hookup imo. You can same-day ship things from Amazon depending on where you live.
Can you upload a picture of your wiring? I'll take a look
Are you certain it's a 1306? That looks an awful lot like my SH1106.
I was able to get mine working in micropython, though it was an 1106 display and not a 1306. https://github.com/jim-p/tnsr-display - links to my code and drivers and so on are there.
No worries it is actually pretty easy. I bought a Chitu screen for about 50 USD:
You can buy from anycubic direct for $70=shipping https://www.anycubic.com/collections/for-photon-series/products/lcd-screen-for-photon-mono
or you can get this one from chitu on amazon for $60 and there is a 5%off coupon right now https://www.amazon.com/dp/B09921BSCL/
My Mono hasn't had that problem, but my friend bought this for his Mono SE when the same thing happened to him.
I used this screen in a recent project and it has the pins on the bottom side. It's just a preference. https://www.amazon.de/DollaTek-ILI9341-240x320-Display-Serielles/dp/B082QVKT7M/ref=pd_sbs_6/262-5995501-6557607?pd_rd_w=2lyf1&pf_rd_p=b1c388c3-48c2-4960-8532-fa8f1477aee9&pf_rd_r=FCFYKJVQMX789NP3TZ9N&pd_rd_r=13866f5e-3b25-4e40-9ac9-508...
Thanks for the detailed response.
I thought this lcd had a microcontroller built into it, so that's why I was trying to push the code to it. I was, obviously, mistaken on that. Although I've tinkered with Pi's in the past (mostly setting up a OctoPrint server on one) the whole adding components thing is something I've been scared to do, and this is the reason why...
I also forgot to put this in the original post, but the lcd is indeed a SSD1306, specifically, this one
So, knowing that I would have to push the code to the Pi, would that override the OctoPrint server on it? If so, is there a way to run both simultaneously? I know that Pi's aren't supercomputers or anything, but I am running the OctoPrint server in CLI and not UI mode, so I would hope just another program running wouldn't be too much for it.
the lib is the Arduino GFX lib, just ctrl F this post for the link, I replied to someone else with it
I really like this idea!
I'd suggest an ESP8266 or ESP32 which you can program with Arduino. Personally I lean toward ESP32 boards these days because it's more powerful and more flexible all around, but you'd probably be fine with a cheaper ESP8266 like a wemos D1 mini. There are a lot of tutorials online for using the D1 mini, so it's a fairly good option.
Running two displays may be a little tricky, depending on the specific displays you want to use. For the number counter, a small 4-pin OLED like this might be a good choice, and there are a lot of options for the larger LCD for the roof. One of my favorite displays is the 240x240 IPS LCDs because it's really crisp, has great color, and excellent viewing angle, but that may be a bit small for what you want.
For connecting the two devices together, there are a lot of different options to choose from. Something like Firestore could work well and would be free and it's hosted by Google so should keep working. The other part to think about is how to get it online - do you know the wifi name and password so you can program them into it ahead of time, or would you need to provide some way to set it up?
How much time do you have to build and get this working?
Feel free to DM me if you have more questions or want suggestions - happy to provide more help for what sounds like a cool project!
Yeah, those are I2C SSD1306 OLED displays, like this: https://www.amazon.com/MakerFocus-Display-SSD1306-3-3V-5V-Arduino/dp/B0761LV1SD/
I second the ZeroScope, pretty easy build (but I totally did accidently buy a color screen and had to desolder it). Here is the correct screen, available on Amazon with prime shipping: https://www.amazon.com/gp/product/B01N1LZQA8/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
I bought my kit from modularaddict as well, but I think vpme.de sells them pre-built: http://vpme.de/
Here is a pretty cheap OLED from Amazon.
HiLetgo 0.96" I2C IIC SPI Serial 128X64 OLED LCD Display SSD1306 for 51 STM32 Arduino Font Color Yellow and Blue https://www.amazon.com/dp/B01N0KIXJ6/ref=cm_sw_r_cp_apa_ddxAybZJZBPPT
> I though that the power drawn by the screen was already counted into the total power use of the pi since it draws the power from the pi's PSU.
For displays that plug directly into the RasPi as a shield, that is true. I haven't seen any 5" LCD screens that were packaged as a shield. Screens that big usually are 800x480, and have a separate HDMI driver board that takes anywhere from 5V to 12V power.
[EDIT] I said that I didn't see any 5" shields, but I did just find a 5" display that is supposedly powered via USB, on amazon.com. In this scenario, you are correct: the screen would be drawing power from the 5v bus provided by the USB hub on the RasPi.
> Also the reason we choose the b+ over the a one is that the proccessing power and the graphics.
As far as I know, the only major difference in the A and B are:
Depending on what all you are trying to run on RetroPie, the A might be easier on your battery.
> Your project also sounds interesting, ive heard of similar projects with the arduino. But what kind of battery where you using and how much battery time would you get from it?
Here's a link of some stuff I've done. I haven't finalized my battery yet. In testing, with an OLLLLD 2000mAh battery I was getting about 2 hours of runtime. This battery had lost quite a bit of capacity over time.
