“SD card corrupted”… again?! 💀
One brownout and Pi-based machines forget everything. Rambutan lives on the router's own flash — no SD card to corrupt, nothing to re-image at midnight.
oksya.com proudly presents…

Built for builders who've seen it all…
If you've built PesoWiFi machines before, these probably haunt your dreams:
SD Card Corruption · Coinslot Offline · Stuck on “Obtaining IP…” · Overheating Pi · Boot… please boot…
Sound familiar? That's exactly why techs switch to Rambutan. Same coin WiFi business — none of the usual headaches:
“Coinslot Offline” (but it's plugged in?!) 🪙
Loose jumper wires and wobbly add-on boards love going offline. Ours wires the coin acceptor straight to the router with just 3 soldered pins. Soldered. Solid. Done.
Forever “Obtaining IP…” 📱
Customers circling the portal of doom is bad for business. Rambutan handles the network per-client, so phones connect, the portal pops, coins drop, they're online.
Less troubleshooting. More machines earning. That's the Rambutan way.
Local parts. Ready-made convert.
Grab hardware from your usual suppliers — we turn it into a Coin Vending WiFi machine and keep it earning all year.
