Smart USB Hub COMING SOON
Built for developers, test benches and USB devices that need to run unattended. Smart USB Hub brings repeatable testing and everyday device routines to your workbench, without the constant plugging, unplugging and reaching for cables.
Use the REST API to switch a device’s power, read its voltage, current and power consumption, and check port status from your test scripts. Repeat a startup test or compare readings across operating states while the other devices stay powered.
Set a different schedule for each port: selected weekdays, a fixed run time, a chosen stop time or repeating intervals. Rules run on the hub, so your browser doesn’t need to stay open.
Open the web interface over Wi-Fi to switch an individual port or investigate a device. Live readings show what it’s drawing; connection and fault status help you see why it isn’t behaving as expected.
Displays, LED art, wearables and development boards. Find your next project idea here.

Turn a suitable toaster oven into a tool for assembling your own boards. Reflow Master Pro manages the soldering profile and shows the temperature curve as it happens.
Start with a built-in solder paste profile, or make it your own. The WiFi interface puts profile editing, live tuning and runtime graphs in your browser.
Project and product creation videos, plus weekly live streams where you can ask questions, offer help, or just giggle along as I make a mess of things or get distracted… They're pretty fun! youtube.com/unexpectedmaker →
