Amazon Prime Day 2021: How to find the best deals

Deals galore and top tips and tricks to help you master Amazon’s sale.

Look, we’ll admit that the most desirable robot gadgets aren’t on this list because they’re not on sale for Prime Day 2021. But if you want to do a little virtual window shopping and come home with something you can put together and tinker with, we have a great little selection.

Oh, and if you’re just getting started with Raspberry Pi making, here’s a quick intro.

Listings are a little sparse heading into Monday night, but we have more coming Tuesday morning, so check back regularly.

ANYCUBIC Photon Mono X 3D Resin Printer

Save 38%

This is a Lightning Deal that begins on Monday 6/21/21 at 5:45PM PDT and ends on Monday 6/21/21 at 11:45PM PDT.

I’ve been testing and working on this in the workshop for a couple of months. It’s an excellent mid-sized resin 3D printer. It has a larger build area than the smaller resin printers that have become so popular, and a monochrome screen, which prints faster and lasts longer.

It’s a great printer at list price, and at 38% off, it’s just a great deal. Just act fast, because even at full price, these run out of stock quickly and regularly.

8 Pcs Mini Car Robot Toys

Save 54%

This is a Lightning Deal that begins on Monday 6/21/21 at 3:25PM PDT and ends on Monday 6/21/21 at 9:25PM PDT.

These are tiny (and at 2 1/2-inches, we mean tiny) little robot transformer-like toys. They’re fun and make great little stocking stuffers and fidget toys for your desk.

This is a Lightning Deal that begins on Monday 6/21/21 at 3:50PM PDT and ends on Monday 6/21/21 at 9:50PM PDT.

This is a great upgrade for a Raspberry Pi. You can add a UI and touch control to any project you’re working on. You know if you need it, and at 25% off, now might be the time to buy.

AOKESI Building Block Robot Kits

This is a great little LEGO-compatible robotics kit that can be app-controlled. If you have Technics parts, this should extend your collection as well.
