Since the logger came back to London, [Willem] was able to do a complete teardown and failure analysis.… Read the rest

Arduino webserver

The Arduino platform should be perfect for throwing together a lightweight webserver because of the availability of quality shields that take care of the hardware for you. As [Ovidiu Predescu] found, there are a few hiccups along the way and he’s put together a guide that covers the workarounds. Specifically, using an Ethernet shield and data logging shield at the … Read the rest

Model rocket GPS and data logger
