Technical engineer looking for a businessman.
The EspUSB is a WiFi-controlled keyboard and mouse. A small dongle fits completely inside a USB port, and creates a WiFi network that you can connect to from your phone. It shares a web page, where you can drag the cursor around, or type in text, and have it appear directly on the computer. A video of it in action is on YouTube. [1]
The original open-source design is by [cnlohr], and is available on Github [2]. It was around from 2016, and I waited patiently for someone to manufacture it so I could buy it on eBay/Tindie/AliExpress/etc. Nobody built it.
Finally I studied the design files, figured out the BOM from the schematics, guessed a load of manufacturing parameters, and got PCBWay to build me 3 prototypes. They work!
I've since updated the firmware to let me type in Chinese, Korean, Japan
Read the rest
ese, Russian, Arabic, Thai, etc - not only English and German. This is particularly important for foreigners in such countries, where it's easier to type on a virtual keyboard on a phone, instead of putting stickers all over a laptop keyboard.
Now I'd like to order more EspUSB devices, so that other people can get them too. 8 people have expressed an interest so far, and one of them wanted 10 units. I can afford to buy 100 units at $25 each from the factory, if I'm confident that I'll have either the money or the devices at the end. I do not want to make a profit on it; if you do, you can keep the money. If you're willing to handle the business side (FCC/CE certification issues, tax, import duties, etc) and assure me that I won't be sued, then I can get you the devices.
