I saw hackaday challenge to build a business card sized project. My wife and I went through quite some brainstorming to find a build that could fit the theme. We try to build something that is connecting two people and make a business card interation more memorable. It takes two people to exchange business cards.... so we thought, why not put a love detecting features. Would be fun to watch two suited people testing if they are in love. Could be awkward, but also could be fun. But for sure something to remember.

# Usecases

Dr. Love is a charming, business-card-sized device that promises to decode the mysteries of love with just a touch. Its compact size and intriguing premise make it an instant conversation starter, leaving everyone curious to give it a try.

Here's the scoop: two people press their fingers against Dr. Love's metal parts for about 10-15 seconds, eagerly awaiting the verdict. Will sparks fly, or will it be a case of "meh"? The anticipation builds as they wait to discover if they're both head over heels or not.

Those 10 seconds of suspense are surprisingly fun, making Dr. Love a decent ice-breaker. As the magic unfolds, conversations flow, and connections deepen. Plus, explaining the inner workings of Dr. Love adds an extra layer of intrigue, keeping everyone engaged.

With its charm, Dr. Love effortlessly steals the spotlight, making it a memorable gift for those special connections. It's not your typical business card giveaway – it's a delightful surprise that leaves a lasting impression.

# How does it work?

Galvanic Skin Response (GSR) is a fancy term that means your skin changes its electrical properties when you sweat. When you get nervous or excited, your body sweats a tiny bit, even if you don't notice it. This sweat makes it easier for electricity to pass through your skin.

Now, think about when you're nervous—like when you're trying to figure out if someone you care about loves you back. You might sweat a little more, right? That's where Dr. Love comes in.

Dr. Love measures this change in sweat using GSR. It has sensors that you place on your fingers or hand, which detect the slight increase in sweat and, therefore, the change in electrical conductivity of your skin. Dr. Love uses this GSR data to guess if someone is in love. If it detects a spike in sweating when you're near someone you love, it suggests that there might be some serious feelings involved.

This technology is used in lie detectors. You know, one of the quirks of lie detectors is their tendency to falter when someone's feeling a bit jittery or excited. Beacuse tends to GSR rises when you are excited can lie detector can't tell if it's the excitement or is it a lie.

But hey, I'm flipping that defect on its head and turning it into a plus. Why not? Think about it: when you're face-to-face with someone you adore, those heart-fluttering moments can easily send your nerves into overdrive. And guess what? That's exactly what I'm banking on with Dr. Love! We're taking those moments of excitement and turning them into a little game of love detection. It's like taking a glitch and turning it into a feature!

But here's the kicker—if you're in a seasoned relationship, you might be cool as a cucumber and not sweat at all. That's why Dr. Love thoughtfully includes the phone number of a divorce lawyer on the cover, just in case!

# Conclusion

This project stemmed from the Hackaday business card challenge, sparking numerous brainstorming sessions with my wife to create something captivating and memorable, akin to the essence of a business card.

We envisioned the business card as a platform for exchanging impressions and fostering connections between two people. We wanted to offer a device that could reveal something about each person involved, transcending the conventional business card functionalities.

After exploring various ideas, we settled on the concept of a "love" detector, inspired by the notion of two individuals engaging in mutual interaction. Unlike a traditional lie detector, which can be tense and one-sided, we aimed to inject light-heartedness into the interaction by detecting "love" instead.

The idea struck a chord with our friends during testing, proving to be an effective attention-grabber and conversation starter. While Dr. Love may not be suitable for all business contexts, it excels in scenarios where a playful approach is welcomed and engagement is key.

Creating Dr. Love brought immense joy, and witnessing...
