My friend saved this one from the trashcan. Because it was defective I offered to repair it for her. Defects The filter retainment clip on top is broken. The vacuum works as intended but shuts off after a short time. When pressing the trigger again the vacuum again works for a short duration. The on-time decreases after consecutive trigger pulls. Issue 1 Scanning The broken clip is scanned with an EinScan 3D scanner. This scan is used as a reference in CAD to model a replacement part.

Features The software runs on a RPi 3b. The handheld features a 3.5′ 320×240 px TFT-LCD screen that I salvaged from a car rear view monitor but via the RPi’s onboard HDMI interface, it can also be connected to a larger monitor. On the front of the device, there are eleven buttons with four additional ones on the back. The backlight metal button on the side is the console’s power switch which is connected to the “PowerBoost 1000C” charge controller with an integrated 5.1 V boost converter from Adafruit.
