我在销售 2500 台 MIDI 录音机中学到的:硬件开发并非那么难
What I learned selling 2,500 MIDI recorders: Hardware is not so hard

在推出 Jamcorder 十八个月后,其创始人回顾了这款自动钢琴录音设备的成功:该产品已售出 2500 台,并建立起可持续的业务。作为一名软件背景的创业者,创始人曾预想“硬件开发困难”这句格言会应验;然而,与编写 20 万行软件代码的复杂性相比,他们发现硬件制造过程出奇地顺利。 作者认为,“硬件的难度取决于你如何设计它。”通过刻意设计简单且价值集中的产品,并保持精益运营,他们避开了常见的制造陷阱。文章最后为有志于硬件创业的人提供了实用建议:精简物料清单(BOM),优先考虑高毛利,与可靠的代工厂合作,并保持严格的质量控制。创始人最终鼓励其他人不要被硬件开发令人望而生畏的声誉所阻挡,只要在设计时考虑到简易性和可扩展性即可。

Chip Weinberger 在文章《硬件并不难》(Hardware is not so hard)中,记录了他销售 2500 台 MIDI 录音机的历程。他认为,现代硬件生产并没有人们印象中那么令人生畏,这主要归功于“站在巨人的肩膀上”——即预认证模块(如 ESP32)、经济实惠的快速原型制作以及便捷的中国代工服务。 Weinberger 强调,该项目真正的挑战在于软件,而非物理电子部分;软件开发涵盖了应用程序、固件和制造工具,代码总量达 20 万行。 **主要观点与社区反响包括:** * **保持简单:** 批评者认为该项目的成功源于其刻意设计的简洁性。他们指出,虽然“Hello World”级别的硬件开发很容易,但涉及模拟信号、高速接口或电磁干扰(EMI)约束的复杂项目依然难度极大。 * **“硬件”的现实:** 资深工程师指出,物流、现金流、合规认证以及防伪策略依然是扩大规模的主要障碍。 * **现代优势:** 低成本原型制作能力和对现有组件的利用,使得硬件开发变得更加平民化,成为软件背景创始人可尝试的领域。 总而言之,此次讨论强调,尽管硬件开发正变得日益便捷,但其难度通常取决于产品的复杂程度,以及开发者管理实体供应链的意愿。

A year and a half ago, I launched Jamcorder.

A Jamcorder connected to a piano
A Jamcorder, in situ.

It marked the completion of two life goals of mine.

First, I finally had the piano recording device I’d always wanted: a fully automated device that captures everything I play, no human-involvement required.

And second, after a career in software, I got to build hardware. It was super fun.

2500 units have already been sold, and counting! People genuinely love it! And it’s able to stand on its own feet as a business. In my eyes, that’s a success.

For my first blog post, I want to reflect on the biggest surprise I encountered creating Jamcorder.

A timeline of early Jamcorder prototypes
A selection of prototypes, from the first prototype to the first pre-production unit.

Coming from a career in software, I expected building hardware to be the hardest part.

After all, hardware is hard. That’s the saying, right?

Electronics design, plastics, manufacturing, fulfilment, component shortages, etc, etc, etc.

I expected these & more to make hardware hard.

But, it wasn’t.

Jamcorders being assembled and packed in a kitchen
To refine the process, I hand assembled the first 500 units myself. It took 4 days. Unexpectedly, everything went completely smoothly and I made no changes. Yes, really.

I kept waiting for something to get me by surprise. A scrapped production run (my worst nightmare). Or component sourcing issues, perhaps?

It never happened. (Though Trump’s tariffs were a close call).

The hardest part of building Jamcorder was still, by far, the software -- roughly 200K lines of code spread across the firmware, app, and manufacturing tooling. It took over 3 years and many long nights in a pre-LLM world.

When compared to that, the hardware was undeniably smooth sailing.

For the record, I don’t think I’m special. It’s just that hardware’s reputation for being difficult is, IMO, overstated.

Now, granted, Jamcorder is -- very much intentionally -- a simple device. I get that.

The Jamcorder printed circuit board
The Jamcorder PCB. 25 unique components. The MIDI connectors are made to order, everything else on the PCB is off-the-shelf.

Assembly is just a single screw, for a single PCB. The injection mold has generous draft, no slides.

I cut low battery detection, ambient light detection, the power-button, even USB-C.

All these things kept Jamcorder simple.

I’m also under no illusion that 2500 units is a lot by most standards.

But you know what? The hardware side would have been easy regardless.

Don’t get me wrong. If Jamcorder was 10x more complex, or 100x more scale, that would be a different story (and a very popular product!).

Or if I was trying to compete in the smartwatch market, or the car market, or any number of very established industries with low margins, good luck.

But for me the take away still is: “hardware is as hard as you make it”.

If you’re thinking about building a hardware product & have a way to protect your margins, don’t let building hardware scare you.

It’s not as hard as the saying goes.

POSTSCRIPT

I don’t want to end this article without some practical take-aways. So here are my top recommendations for successfully shipping hardware that worked for me at medium scale:

  1. Keep your BOM simple. Avoid single-manufacturer components wherever possible.
  2. Avoid complex assembly and calibration.
  3. Partner with a Chinese assembly house and suppliers. Alibaba is your friend.
  4. Aim for at least 70% gross margin or more.
  5. Keep your company lean. Scaling hardware is slower.
  6. Have a strong anti-counterfeit strategy. Don’t overlook this.
  7. Do final Q/A in-house & hold finished inventory locally.
  8. Request samples before every production run.
  9. Write a step-by-step manufacturing & assembly guide with pictures.
  10. Keep your packaging small. A value dense product makes everything easier.
