Problems we have already solved
Our client work is under NDA, so these are described by the engineering problem rather than the product. The constraints and the decisions are real. Ask us about any of them and we will go as deep as the agreement allows.

Getting data off an FPGA, and into hands that need it
A medical instrument generated high-rate data inside an FPGA with no reliable way to capture it off the device, and no interface anyone but an engineer could operate.
- Acquisition software that streams from the FPGA without dropping samples
- A documented host-to-device data format instead of tribal knowledge
- Operator GUI for live capture, review, and export
Engineers and operators work from one tool rather than ad-hoc scripts.
Talk to us about a project like thisA status light people trust at forty meters
An alert indicator needed to stay legible across a noisy plant floor and fail into a safe state when the network dropped.
- Optical and driver design for wide-angle visibility
- Fail-safe state machine covering power loss and link loss
- Enclosure and mounting specified for the environment
Pilot units validated on-site before the production order.
Talk to us about a project like thisA carrier board that outlives its compute module
A single-board computer needed a custom carrier exposing specific I/O, without redesigning every time the module was revised.
- Carrier PCB with a stable connector and power architecture
- Device-tree and driver bring-up on embedded Linux
- Documented flashing and provisioning for the assembler
Boards brought up and handed off with full source and ECAD.
Talk to us about a project like thisMotor control in a tool you hold all day
A cordless tool needed usable torque and runtime in a housing constrained by grip ergonomics and thermal limits.
- Motor drive and battery management sizing
- Thermal path worked with the mechanical design, not after it
- Safety cutoffs and a charge strategy matched to the cell
Working prototype tested against real duty cycles.
Talk to us about a project like thisA connected display that a non-technical buyer can set up
A gift-market product needed Wi-Fi onboarding that ordinary buyers complete without support, and content delivery that keeps working years later.
- Provisioning flow designed for the least technical user
- Backend contract and update path defined up front
- Cost engineered against a retail price the product had to hit
Prototype and cost model delivered for a go/no-go decision.
Talk to us about a project like thisElectronics that survive dust, vibration, and washdown
Field equipment needed sensing and control that keeps working through vibration, temperature swings, and regular cleaning.
- Sealed enclosure and connector selection for the duty cycle
- Sensor conditioning with real-world noise accounted for
- Serviceability designed in, so field repair is possible
Design validated in the environment it actually runs in.

"We brought inteRFace R&D in to build the software side of our medical device, including data acquisition from our FPGA based hardware and the GUI our team uses daily. They were dedicated, thorough, and easy to work with throughout. Highly recommend them for serious hardware and embedded software work"

Frequently Asked
Questions, Answered
Prototyping turns an idea into a working model you can hold, test, and iterate on. It lets us de-risk technical choices, validate the user experience, and catch problems before you invest in tooling or mass production.
Simple prototypes can be ready in a few weeks. More complex products involving custom PCBs, firmware, and mechanical design typically take 8–16 weeks. We'll give you a concrete timeline after our free consultation.
Every project is scoped individually based on complexity, materials, and timeline. Contact us to schedule a free consultation — we'll give you a clear, itemized estimate with no obligation.
Yes. We treat every project as strictly confidential and sign a mutual NDA before any technical discussion. Your idea never leaves our team.
Never. You retain 100% of your company equity and intellectual property. We're a service provider, not a co-founder — you own everything we build for you.
An idea and a free consultation. You don't need a spec document, CAD files, or a finished design. We'll help you shape the concept from wherever you are today.
