T400 September Production Update

Here is a quick update on the T400 temperature datalogger status. In short, there are not obstacles; it is only a matter of doing the work to finish things up. Here is a video walking through (what several days ago was) the latest prototype. In the video I take you through the user interface and [...]

Thermocouple connector progress

I am thrilled to announce we have overcome the single greatest obstacle to our forward progress: custom thermocouple connectors. There are a few manufacturing consistency issues to work out, but the design is sound and the connectors work.

Thermocouple connector prototypes

Two months ago we completed our thermocouple connector design and sent it off to the sheet metal factory. They said we would have prototypes by mid June. As expected, they were about one week late, which is pretty normal. Then they wanted more time. We pushed the factory to give us prototypes before the Dragon Boat Festival in late [...]

The T400 appears at MakerFaire NYC

Alasdair Allan wrote a wonderful article about the T400 and open source lab instruments at MakerFaire NYC. It was a real treat speaking with Allasdair and everyone at MakerFaire who experienced the T400 and really get it when it comes to lab instrument access. The main problem with lab equipment is that it’s expensive. Often [...]
