I upgraded one of my machines with another LMS-ESP32 from Antons Mindstorms, and attached an ILI9341 touchscreen to it.

Previously it was on the EV3 screen only, which has no backlight and is a black/white pixels screen only. It also has 5 buttons only to operate the settings. The touchscreen makes it much clearer what is happening, howmany pins have been sorted, what the last pin was (I highlight it green).

The ideas for further advancing the touchscreen program could be;

• Adding a limit for a certain type of pin, so for example bin only 100 of each, if #101 is scanned, put it back in the hopper by reversing the scanning belt.
• Adding a limit for bagging a certain number of pins. If you want to make ziplock bags of 100 or 500pins each, have the arm stop filling a bin and put it on pause, or start filling an other not yet defined bin.

During the adding of the ESP32 I also relearned the EV3 the values to recognize each pin, which makes it for now faster to be 100% sure a pin matches the library.

This machine will normally be at an event 28-30December together with my Logistics Warehouse, where I used this ESP32 and touchscreen for the first time.

And it has been running for over 25hours this week. A short video;

First motor broken after 100+ hours running this year at events + many more at home testing+programming. Still need to open it up to see why it's not turning at all. An original cable also had an issue as the EV3's don't know what motor is attached anymore when using that cable, a swap with another cable resolved the issue.

First time I applied silicone spray at the lifting guides of the high bay stacker crane, before the event started, never had to redo homing because of this during a day. Will need to spray some gears in the robot arm soon as well.

Really cool project and addition to an already amazing display of automation possible with Lego!

Shame about the motor, hopefully it's salvageable somehow.

I would also check the contacts of corrosion, due to different humidities in transportation / exibitions those may give additional issues.
