FIELD NOTES
Plain-English writeups from the bench — what hardware development really costs, how to buy it well, and how not to get burned. No fluff, real numbers, written by the engineer who does the work.
Custom bioreactor design, what it takes and what it costs
A custom bioreactor is worth building when your protocol needs a vessel geometry, flow, or sensing that no catalog unit provides. Here is what goes into one, what the parts and the engineering cost, and when to modify a catalog unit instead.
read →How to turn an idea into a product
Turning an idea into a product is a sequence of small, decisive steps, not one big build. Here is the honest path, what each step decides, what it costs, and how to hire for it without getting burned.
read →How to spot an invention-promotion scam
You have an idea and some money, you search for help, and the first companies to find you sell patents and marketing, not products. Here is how to tell an invention-promotion firm from a real engineering one before you spend a dollar.
read →When a hardware project stalls, how to restart it
Developer disappeared, prototype half-works, or you inherited an undocumented rig? A stalled hardware project can usually be restarted. The first step is an honest diagnosis, not more building. Here is what a rescue involves and how to judge whether yours is worth finishing.
read →Custom lab equipment without the instrument-company markup
The instrument your experiment needs doesn't exist in any catalog, the big vendors quote five figures, and the student who built the last rig graduated. There's a better path — including the purchase-order lane your department can approve directly.
read →What a hardware prototype actually costs in 2026
Quotes for the same idea range from $3,000 to $300,000, and almost nobody publishes numbers. Here are the real ranges, what drives them, the three ways people overpay, and when you shouldn't build at all.
