Control IO 3

Summary

The Control IO 3 is a pre-made reflow oven used by Sean Hodgins in the episode "GPS Has a Secret Job" to solder surface mount components. The device represents a significant upgrade from Sean's previous method of using a $20 toaster oven, which required manually monitoring the board and turning off the heat when components reflowed. The Control IO 3 features improved insulation, an automatic servo mechanism that opens the door, and programmable temperature profiles including lead-free settings. Sean notes that while he purchased the pre-made version, there is also a DIY project available for those who want to build their own reflow oven.

What Was Said

Sean Hodgins presented the Control IO 3 as a notable improvement in his electronics workflow. He explained his previous setup: "So, I used to use this $20 toaster oven that I just would turn on, and then I would just look and see when it reflowed, and then I'd turn it off." This manual process required constant attention and timing judgment.

In describing the upgrade, Sean highlighted the Control IO 3's features: "So, now I've upgraded a little bit to this Control IO 3, which is a like a pre-made one. You can do the project, but to build your own." He emphasized its automated capabilities: "It's better insulated. It's got an automatic servo that opens it up, and it's got profiles that it runs."

The oven's operation was demonstrated as straightforward and hands-off. Sean explained that after placing a board with solder paste and components inside, he would simply select the lead-free profile, hit run, and wait for the completion notification. This automated approach eliminated the need for manual monitoring and timing decisions that characterized his previous method.

History

GPS Has a Secret Job

The Control IO 3 appeared in this episode during the construction of the PPS Watch Project with Jeff Geerling. After Sean and Jeff placed solder paste on the circuit board and positioned the surface mount components, the Control IO 3 was used to complete Jeff's first SMD soldering experience. At 14:56, Sean demonstrated running a reflow profile to solder components on the circuit board. The oven ran an automated lead-free reflow cycle, handling the temperature profile without requiring manual intervention. This marked a practical demonstration of how modern maker tools have evolved to make complex electronics assembly more accessible, even for someone attempting their first surface mount project.
