Cryptofolio VS twinkle-tray

A while ago, I made a self-hosted and open-source cryptocurrency portfolio app using React Native. Since it's only my 2nd or 3rd RN project, there's a lot of improvements I want to make in the next iteration, and the code is a little all over the place as I was learning while winging it half the time. For now, you can check it out here: https://github.com/Xtrendence/Cryptofolio

Hi, I'm developing an app that uses the CoinGecko API, and currently, I have a feature where users can view the performance of their cryptocurrency holdings over the past year. To do so, N number of requests are made to the "/coins/{id}/market_chart/range" endpoint, where N is the number of different coins the user has in their portfolio. This works fine when there aren't that many coins, but beyond a certain amount, requests have to be made with a delay between them to avoid hitting the rate limit, and since my app makes other requests multiple times per minute, the aforementioned amount isn't that high.

Glad to hear it, if you have any suggestions or feedback, then please do provide it. I have a project board with upcoming features, so if you feel as though there's a useful feature (within the scope of the project) that could be added, then either just reply/message me here or open an issue on the GitHub repo. Thank you!

Well, unfortunately that will never happen because the app would need a full rewrite using DirectX and WinAPI.

Fortunately there’s an open source alternative called TwinkleTray: https://github.com/xanderfrangos/twinkle-tray

Someone determined enough could add adaptive brightness to it. You can even use Lunar’s wireless ambient light sensor [1] for that as it’s simply sending lux values through Server Sent Events [2]

I've seen monitors with physical brightness/contrast buttons, but it's a difficult feature to search for. You have to see them in person or maybe look at their manuals before buying.

In the meantime, have you tried the DDC/CI protocol (https://en.wikipedia.org/wiki/Display_Data_Channel)? It's a software protocol for controlling real monitor brightness/contrast (as in, it commands the hardware, not just drawing gray overlays).

Update : there a beta version that works here, but it might have some bugs like no sleep.

Yes, the dev responded here and basically said it's a Windows bug.

ATTENTION: You'll need a pretty recent PC to run this screen tablet, as well as alot of USB ports, HDMI, and a free power outlet. Also a program called Twinkle Tray (1.14.0 Beta) as it gives you better control over brightness and contrast of the screen (because the driver sucks in terms of convenience)

Op, you need a nifty little tool called Twinkle Tray
