Code whizz and tinkerer Kian Ryan’s ingenious “Sidecar” is a self-contained, battery-powered Wi-Fi-to-RS232 bridge that enables his elderly Psion 5MX PDA to access a little bit of the modern internet.<\/p>\n

The Sidecar<\/a> is an inspired homemade device which combines an assortment of bits of hardware and software, a 3D-printed case, plus considerable ingenuity, to create a pocket-sized gadget that turns a vintage mobile computer into a mobile Linux terminal \u2013 and which can also permit elderly gadgets access the internet.<\/p>\n

You can trace the development of the Sidecar over six months on Ryan’s blog<\/a>. Back in June, he described<\/a> a fairly complicated setup. This used a MAX3232-based<\/a> [PDF] RS232-to-TTL level converter, plus a gender-converter and<\/em> a null-modem adapter to hook a Psion serial cable to a Raspberry Pi Zero. (He didn’t mention it, but we think it must a Pi Zero W to provide an upstream network connection.)<\/p>\n
