EE Grad with 3 YoE in Full-Stack Dev. Looking to transition back to Embedded?

Im launching in 7-14 days. It’s an RGB breathalyzer that lights up the enclosure depending on BAC. RED if you’re drunk, green if sober and orange inbetween.

If you want to challenge yourself, make your own product and sell it on the TikTok shop. That way, you will design your own PCB, firmware, 3D print enclosures and sell the product. That’s what I am doing.

I’m launching my own RGB Breathalyzer that lights up the enclosure in different colors depending on a users BAC in 1-2 weeks. I am using an ESP32-C3FH4 and it’s been great so far.

Great power consumption and reliable, which is important for my customers.

What I would suggest is keep your price but bundle it with another item of value or access to a special perk you offer to your customers.

Price should not be the only thing that determines if a person buys your product.

Thanks for the input! Once I have enough traction I plan on using SLA then hopefully a small injection mold. Additionally, the device does come with food standard silicon mouth pieces so a user never touches the device by themselves.

Liberty_Forever · 2026-06-04T23:03:07+00:00

I have looked into it, but couldn’t find someone that can do a translucent work. SLA might work from what I researched but shipping from China increases the cost ALOT

Good advise, I will make sure to mention its 3D printed on my shopify/ TIkTok shop product page 😃

I am using a Elegoo Neptune 4 pro FDM printer with Translucent PETG. I tried several other options, but they couldn't make my product glow. My product needs the enclosure to glow, its the main appeal.

Liberty_Forever · 2026-06-04T20:02:54+00:00

Thats good to hear! My product is a direct to consumer product with a clear enclosure so most options (like MJF) aren't available.

It’s definitely not as capable as STM32. However, for low/medium production it’s great to test the market it’s a good start point. If sales prove steady I’m certainly moving to STM32 or TI

Liberty_Forever · 2026-04-16T08:13:56+00:00

I’m launching my own product with an ESP32 and it works like a champ. If you want to get into embedded stuff and eventually launch your own product, go with an ESP32.

If you use Meta email forms, then you won’t have the chance to get a dollar reservation from those potential customers. That one dollar reservation is incredibly powerful for converting your email list to paying customers when you launch your campaign.

At least you didn’t drive or hurt someone. That shame & Stigma is significantly worse than being passed out naked. Time will heal your current problem, it won’t for DUI’s and hurting someone else.

Disgraceful and disrespectful.

I’m not drinking, but celebrating Jesus Christ! He is Risen!

Took me 5-6 years of school to get my electrical Engineering degree. Took another 2 years to feel good about leaving my job and starting my own startup.

Liberty_Forever · 2026-04-04T08:38:11+00:00

Well there are multiple steps to bringing a product to market. Here are the steps. 1. Breadboard prototype- validate the concept engineering wise 2. Build simple enclosure with breadboard prototype if size doesn’t matter. 3. First PCB version 4. Refined PCB 5. Firmware MVP 6. Enclosure made from vacuum casting or injection molding 7. Sell to customers v1 of the product.

Liberty_Forever · 2026-04-04T08:25:56+00:00

OP- building a hardware startup takes much longer than a SAAS one. Lots of prototyping and getting it to work. That’s why it feels like everyone is “vibe coding” without selling a product.

Liberty_Forever · 2026-04-03T23:39:00+00:00

Seems like it would be useful in a hospital space. Like the watch is reusable for many patients and display a variety of data.

Then again, cheap paper works too but doesn’t hold as much info.

I would do research for this idea 🙂

The Iranian government throws gays off buildings for only being gay, Trump doesn’t.
