[2023 DigiKey Contest Participation Award] Unboxing Post: The Latest Participation Award, the Most Cyber-powerful Glasses [Copy link]

 

I have to say that this event is very good for the sponsor to give engineers many new and interesting things. The 2023 DigiKey competition participation award was originally placed in May. At that time, an SDR (software radio) receiver was selected.

At that time, the mall wrote that the delivery date for futures was June 22. However, I waited and waited until July 15 and there was no movement. I contacted Kathy, a domestic specialist, and she said that futures did not include delivery dates, so I had to wait.

PS: It is important to remember whether to buy components in spot or futures. Estimates are just estimates and cannot be trusted. After all, no one can be sure of the changing market.

I couldn't wait. Then I applied for a return with the specialist. After all, there is still a cycle.

Some people are curious about what they bought before and why it has not been delivered for two months. Software radio is used to receive shortwave radio signals and is played by many radio enthusiasts. Unfortunately, the weather was not good and I didn't play it this time.

I quickly placed an order for spot goods and received it in less than a week. It went through the United States-Customs-Shenzhen, China-Shanghai. I have to say that global logistics is very powerful.

This time I bought something very interesting.

The box is not small, the packaging is very tight, and the tape is very interesting, it seems to be paper and thin plastic strips for internal reinforcement.

This bag is not the static-proof kind, it's an ordinary one, and it feels quite thick.

The protagonist appears, the cyberpunk glasses are actually used to visually inspect some circuit details.

The built-in LED on the board has poor soldering. This is a better choice for small components.

This manufacturer also provides many lenses with different magnifications, but the author has not had time to play with them carefully.

I bought a car cigarette lighter to charger.

It is more delicate and has no burrs, much better than the 30 yuan one on Taobao.
