A team in Colombia is to test a ventilator made with a Raspberry Pi computer and easy-to-source parts.

The design and computer code were posted online in March by a man in California, who had no prior experience at creating medical equipment.

Marco Mascorro, a robotics engineer, said he had built the ventilator because knew the machines were in high demand to treat Covid-19.

"I am a true believer that technology can solve a lot of the problems we have right now specifically in this pandemic," he told the BBC.
