You do not need to learn electronics to get a gadget made. You need to say clearly what it does, answer a few questions about it, and see a first sample before you commit to more. This page walks through that, and says when not to build it at all.
What to write down first
One paragraph: what the gadget does, who uses it, where, how it gets power, and roughly how many you imagine making. A sketch or a photo of something close helps. That is enough to start. A full specification comes later, and the engineer writes most of it with you.
The questions an engineer will ask you back
For almost any gadget, the cost turns on a handful of choices: the power source (battery, plug or USB), whether it is wireless and how, the enclosure, whether it has a screen, and which sensors or certifications it needs. Expect to be asked about the three that matter most for your idea, and one question that has to be answered before anyone can put a number on it. That is exactly how Anvol replies when you tell it an idea.
Check what already exists before paying anyone
Search for products that already do most of it. If one is close, buying it, or building on it, can answer your real question for a fraction of the cost. If what you want only makes sense as a feature of a phone app, say so early; a good engineer will tell you when a device is not needed.
Works-like before looks-like
A first sample proves that the thing works; the finished look comes after. Y Combinator's advice to hardware startups separates the two for that reason. Buy the hard parts where you can: one answer in a Hacker News thread on bringing hardware to market puts it plainly: at small volumes, "if you can buy your power supply, you should".
Why people say "plan for 1,000 units", and why a first round can be one
The same thread warns that almost everything in hardware has a minimum order or is uneconomic at small volumes, so you should "plan to make 1,000 units". That is true of a production run. It is not true of a first sample: with Anvol the minimum for a prototype is one unit, and a small batch of tens to hundreds comes after you have held a sample you approved.
What a first sample round gives you, and when you pay
Telling Anvol your idea and getting a cost is free. A 30% deposit starts a sample round; the balance is due after you approve the physical sample. The round ends with the sample and the files behind it: schematic, enclosure 3D model (STEP), test report, photos and video. How prototypes work.
Who owns the idea?
Your project on Blockless is private. Anvol is a product, not a shareholder: you own what you make. For a build you pay for, the rights are set out in your project agreement. If you would rather share the cost and the profit, building together is the other way.
When not to build it
If a product on the market already does it well enough, if it only works as an app, or if you would not pay for the first sample yourself, stop there. A cost is not a guaranteed final price or delivery date, and nothing is charged or started without your approval. How Anvol works · More answers · What an AI cofounder for hardware is.
