Button-mashing, but make it chic
Show HN: Creavi Macropad – Built a wireless macropad with a display
Solo maker turns flop into a slick wireless button box — HN cheers the glow-up
TLDR: A solo builder made a wireless mini keypad with a screen after many failed tries. Commenters praised the polished look and swapped tips on chips and display software, with light debates over wireless vs wired and DIY vs buy—useful inspo for anyone dreaming up their own gadget.
The internet loves a comeback, and this one comes with clicky buttons. A solo tinkerer just unveiled a tiny wireless “button box” with a screen—aka a macropad—and the Hacker News crowd instantly swooned. One early chorus: it looks “real professional,” with multiple users marveling that this isn’t a crowdfunded gadget, just a determined human finally shipping a dream.
Then the nerdy lovefest kicked in. Curious minds begged for details: is it powered by an ESP (a tiny Wi‑Fi/Bluetooth brain)? Is the screen running LVGL (a library that draws graphics on little displays)? A veteran chimed in with battle scars, praising the build while admitting they used to skip “invisible gremlins” like parasitic inductance and now religiously follow datasheet checklists—translation: add the boring parts, your device won’t explode.
Of course, the usual mini‑dramas bubbled up: wireless convenience versus wired reliability, DIY pride versus “just buy a Stream Deck,” and the eternal “open-source files when?” The meme of the day: the maker’s own rallying cry—“How hard could it be?”—echoed back as a collective “famous last words” wink. Still, the vibe was overwhelmingly wholesome: a project born from failure, polished by persistence, and celebrated by a comment section that felt like a workshop’s cheering squad.
Key Points
