Below is a massive listing of items pertaining to Arduino, Internet of things (IOT), mobile robotics, hobby robotics, brushless motor control, stepper motor control, hobby robotics platforms, Raspberry PI, NVIDIA Jetson, brushless motor drivers, stepper motor drivers, dc motor drivers, hobby electronics, DC electronics, Larger hobby lcd's, esp32 wroom, esp32 with lcd (amoled versions), RC, and much more. I have listed individually but also will consider larger offers. My projects are now complete and I will be getting rid of lots of Nickle and Dime type items that can really add up. All items are marked down from retail and still add up. Let me know what you are interested in or looking to build. I might have more listings coming soon depending on interest in these types of items. All tested to be functional and working or factory sealed. Most items have been used once or twice just to understand how they work and kept indoors.
Arduino Lot:
I moved to the ESP32 platform as it cheaper than working with Arduino at $20-$30 each, ESP32 has some extra functionality and in general I preferred the platform. You can also get with built in LCD. Arduino is more like $20-$40 per device.
Amazon $10. Doing 3 for $20. Have probably 20 total.

Have a few of the LCD version from Lilygo. Great to work with. Cheaper version asking $20 each, have 3:

If anyone is interested, the best way I have found to program visual things on the esp32 is this little bench top setup. It has 4x LCD's and slots for 4x esp32 so each can control its own LCD.
This is the picture with 4 screens.
4x esp32 see above link for esp32.
4x LCD see below link:
Amazon: https://a.co/d/0bkcdoti
Amazon $18 each.
4 esp32 ($10 each) and 4 LCD ($17 each). $75 takes them all. If you are doing this type of thing, this helps a lot.
Here is a separate setup. LCD hot glued to 3d printed stand. Asking $40. Takes standard HDMI and micro for power. Common cords but not included.
Arduino + motor controllers = Move things in real life. Below are some motor Controller drivers.
Separately selling a logic analyzer. These are great for testing things out. LA1010 seen here:
Amazon: https://a.co/d/0bYSMWdl
Amazon $70. Asking $50.
Standard DC:
Brushless DC:
DC 6-60V 400W with stop functionality
Amazon: https://a.co/d/02Lz7rZP
Looks like $20-ish each on Amazon. Would take $75 for the 6.
Stepper (Big ones: normally used in CNC and various metal milling operations):
DM556T:
Looks like $20(2 week lead)-$40 on Amazon would take $20. Brand new tested functional. Also have stepper motors separately. Have 1x.

TB6600:
Amazon: https://a.co/d/0dBKi6HG
Amazon $10 each. Would do $30 for the 4x.
Including pictures of various junk drawers. Lots of hobby robotics items for $5-$10 will look at on a case by case. Make me an offer on a drawer and the drawer you are interested in. Thinking $50-$100 per drawer worth of stuff. I'm keeping the actual drawer. Have pulleys, bearings, wiring etc. Thanks for your interest.
