Design Review
Independent design reviews are one of the best ways to lower your design risk and cost before prototyping a new product.
Whether you are doing the design yourself, or outsourcing it to a developer, getting a 3rd-party design review is always the smart thing to do. It's much easer and cheaper to catch design issues earlier, ideally before you pay for prototypes.
We offer design reviews for both the schematic circuit diagram and the PCB layout.
We follow in-depth checklists for all design reviews so you know you are getting a thorough review of your design. Here is the checklist we follow for schematic design reviews and the checklist for PCB layout design reviews. These are the same checklists included with your Hardware Hack Pack.
You are welcome to purchase a design review now at the discounted price, but use it at any time in the future when you are ready. You can also use the schematic diagram review first, and then do the PCB layout review later.
Design reviews typically take one week to complete.
Normally, we charge $599 for a complete review of your custom electronics design, but if you purchase now you will save $200 and pay only $399.
Lower your risk of costly design mistakes by getting an independent design review done by expert engineers.

Hey there, I’m John Teel, a product design engineer, serial entrepreneur, and the founder Predictable Designs and the Hardware Academy.
As a senior design engineer at Texas Instruments I designed dozens of successful electronic microchips. My designs can be found in all kinds of popular electronic devices including some from Apple and Intel. You likely own a product or two with one of my chip designs inside.
Before starting Predictable Designs, I founded a hardware startup named MicroLite Tech that developed and manufactured consumer lighting devices. My product was sold in hundreds of retail locations across multiple countries.
In addition to developing the product I also oversaw manufacturing in China, marketing, trade shows, logistics, financing, and sales. I had a team of over 20 sales representatives across the U.S. selling my product at one point.
For the past 5 years my full time passion has been helping entrepreneurs like you to develop and bring new electronic products to market. Over 42,000 hardware entrepreneurs just like you have subscribed to my Predictable Designs blog.
I received my Master’s in Electrical Engineering (MSEE) degree from the University of Texas with a focus in Microelectronics.
As a member of the Hardware Academy you will always have priority access to me for help and advice. There is even a private consulting area inside the Academy if you need to discuss anything confidential with only me.
