There are some other one-offs as well, but the best bet IMO would be to reach out to
@maxvapor710 about ordering a custom unit with a touchscreen.
In regard to the community project, the confusing stuff is regarding an original implementation that is not based on the hex-nail software stack; that's further down the road, and a much better future for the community project (though I will still be working on the hexnail-based version until that is further along). If you're interested in building a hexnail, I'm putting together a repo and tutorial for doing so this weekend, and I'll eventually be purchasing and trying out a screen. Once you have it ready to go, adding a screen is as easy as installing the screen as per the well-documented tutorials available, installing a display manager (automated through packages, no linux experience necessary), and then navigating to the local webapp instance in a browser. If that's a foreign language to you, you may want to wait until I've automated configuration of that in the repo. When I get around to doing that I'll make a tutorial but that's at least 3-4 weeks away, if not more; got a lot of other projects I'm working on, too.
Unrelated:
If anyone is referencing my post above, please note that "chown -R hexnail: /opt/nail/" should be done before running the python script, and the reboot at the end is unnecessary (the python script reboots the machine at the end). Also, configuration is only that simple if you already have a working hexnail installation; those steps will not work on a fresh OS install, but I will be releasing a tutorial for that this weekend. Also, I fixed my wiring issue and the latest wiring diagram is incorrect. When I post the tutorial I will also put an updated diagram.
It took a while but I desoldered everything from the orange pi on my official unit and added pin headers, so now my official unit is using dupont connectors for easier cable management and maintenance. Since doing so, my coil readings are not accurate (but they are consistent), but somehow my nail temp guesstimate is extremely accurate. Yesterday I was running it set to 630, the estimated nail temp was ~450, IR gun was 430-460, and thermocouple was 465. To everyone who complained about getting inconsistent behavior, you either have something misconfigured or there's a wiring issue. Since rewiring, mine has worked really well, regardless of the temp it thinks the coil is at.
