Technology blog network Engadget, brought their final event of the year to the Belasco Theater in Los Angeles on Friday evening, giving gadget lovers an opportunity to look at some technological innovations and network with fellow tech-heads.

There was a line outside the venue and inside crowds had already formed around booths that gave freebies and offered demonstrations of the products.

For three hours the theater was filled with loud music while people enjoyed cold beverages and were able to get a sneak peak at some of the latest developments in technology.

Sponsors such as Huawei, a global networking and telecommunications company, gave freebies to anyone who signed up for their newsletter. Iolo Technologies, an internet and productivity and software development company, offered free trials of their computer enhancement optimization software, System Mechanic.

Virtual reality hardware and software development company Jaunt VR, had their Oculus Rift virtual reality headset for attendees to experience. The headset put attendees on the red carpet for the Guardians of the Galaxy s8 premier, an Avicii concert and even submersed them in a horror movie, which resulted in screams from some users who felt completely immersed.

Scott Broock, vice president of content for Jaunt VR, showed the headset and passed around a smartphone paired with Google’s do-it-yourself virtual reality viewer made from cardboard that provided a similar experience.

People who own Android smartphones can experience Google Cardboard by downloading the app along with gathering the items that are necessary for the construction of the headset.

Another sponsor with long lines was Vapshot, attendees over 21 could inhale vaporized alcohol.

Home security technologies had a presence at Engadget Live. Ring Video Doorbell from Doorbot has motion detection and two-way talk that allows users to monitor what is going on outside their home. Homeowners who have this device installed can use their smartphones or tablets to find out what is happening at home and have a video conversation with someone standing outside their door.

The expo brought technology aficionados and novices together so that everyone who appreciates the tech world could experience cutting-edge products and learn about the companies that develop them.
