When I was a kid, I made several guitar and bass amplifiers for myself and my friends. I made one as a trade for a Ibanez Chorus pedal.
I did everything, "from the scratch" except components and speaker units. I had metal panels cut by somebody else, I didn't have way of cutting it.
The wooden box, veneer, PCBs, everything. Schematics were painstakingly made by designing some parts by myself, and partially by reverse engineering several Peavey, Acoustic, Ampeg and other amplifiers.
No Internet then.
I didn't whine how life is unfair because Peavey didn't make a version of amplifier with full schematics and operating principles and with detailed know how how to tweak preamp or equalizers for you to be able to change two capacitors and than have bragging rights that you "improved" great amplifier...
I did make dozens of modifications on people's amps when they wanted something tweaked. But I did it myself. And I had a reputation of being goto guy for that kind of work.
But that was all my effort.
Nowdays, people want for manufacturers to spend 30 engineer/years to develop a product, and then to "open it" (mean give all connected "know-how" for free) so few users that didn't buy soldering iron to actually use it, but to play with the iron itself, can brag on the youtube something like : "SHOCKING: New release of jailbreaked firmware "Blue fire 2" for PACE ADS200 improves soldering time of pennies for more than 2% ... (DISCLAIMER: "Blue fire 2" firmware damages soldering tips after 2 hours, but speed increase was totally worth it....) And then 10 minute video of a guy soldering pennies together..
I bought ADS200 EXACTLY because it is no nonsense, honest to God, just excellent soldering iron. You can set temperature, you can solder with it. It has fantastic choice of tips, it is very powerful, yet very compact. You want touch screen, buy JBC.
People that don't use soldering stations as a tool, but actually want to tinker with station itself are not target market of pro companies. Sorry, it's just so.
Don't like that? Reverse engineer board. It is very simple actually. Reverse engineer it, make whatever you think is cool, and make it open source.
Make it so it can be installed in original controller as an aftermarket change. Or make whole different front panel (can be PCB style) that can be installed in a box.
And put that in open source. Whoever does that has my respect. Huge respect.
But you do that on your own time, with your resources and knowledge, with your own responsibility.
Asking somebody else to do that for you is kinda lame...
