Berlin’s tech startup scene isn’t all about e-commerce and apps – there are a few hardware startups in there too, and one, Pockethernet, has just launched a $50,000 Indiegogo crowdfunding campaign for its rather handy piece of kit. Aimed at network admins and other technicians, Pockethernet is a small Ethernet cable tester and network analyzer that hooks up to your smartphone via Bluetooth. The benefit here is that the brains of the device are offloaded to the handset, which cuts costs and allows for easy upgrades. The $200 retail price is a far cry from the $500+ you’d pay for more traditional Ethernet network analyzers. It may not be sexy, but it is smart.
