This food sealer just wasn’t cutting it for [Tinkering Engineer], so he decided to do something about it. The issue with this sealer was that it didn’t have a mode where it could simply seal bags without pulling a vacuum on it. Going through the whole process takes a reported 40 seconds in order to evacuate the air and then seal the bag. Without pulling a vacuum, the sealing process took only 9.

After taking everything apart and looking around, a PIC microcontroller, and vacuum switch were found as well as other assorted electronics. Although the first thought was to replace the onboard PIC with an Arduino, a much simpler solution was arrived at. Two switches were added, one to disable the vacuum pump and the other to manually turn on the heater. This would allow the machine to function as originally intended or simply let bags be sealed without the vacuum function.

This hack may not be the most advanced one that we’ve ever seen, but it’s a good reminder that some projects can be done very simply if you’re willing to look around!
