Electronics for Small Projects.

Design and manufacture of electronics for small projects and simple projects.

Not every project needs to be complex to be clever. At Winter and Smith, we’re just as happy designing small, focused circuit boards as we are tackling bigger builds. Electronics for small projects often solve very specific problems, saving our clients time, money, and future hassle.

Small electronic monitoring project

This small board was designed to sit inside a water control valve and report its status to a monitoring system. It did more than just check if the valve was open or closed, it could also detect if the wiring had been damaged or shorted, such as by accidental drilling.

This made it a true monitored alarm circuit, ideal for high-reliability applications!

And what started as a quick design turned into a long-term success with over 5,000 units manufactured

USB-controlled LED light

A client had prototyped a system to turn on an LED strip using a Raspberry Pi, but that approach was costly and excessive for such a simple task…

We redesigned the board from the ground up using low-cost microcontroller components. We also created the firmware and PC-side control software, resulting in a compact, USB-powered LED control solution that was both efficient and affordable.

USB interface for peak flow meter

This project started with a client’s early-stage prototype; a full schematic and bill of materials. They needed a production-ready PCB that could pass regulatory testing.

We laid out the board, built initial prototypes, and supported them through EMC compliance testing. The finished product passed first time, and we’ve since helped produce thousands of units, giving their healthcare product a long-term, professional future.

Small flowswitch circuit project

An equipment manufacturer needed a very tiny board, just 1cm x 3cm, that could fit inside an existing device. It had to be easily configurable, durable, and simple to install.

We created a tidy solution with onboard screw terminals, pre-fitted wiring, and a flexible setup to adapt to different use cases. It was small, smart, and effective, with nearly 8,000 made to date!

Electronic payment upgrade interface

What do you do when you’ve got thousands of cash machines out in the world – but no one carries cash around anymore?  That was the challenge facing one client, whose coin-operated units were seeing a drop in usage. They sourced a contactless card reader, but needed a way to connect it to their original system without a full redesign.

We designed a plug-in interface that slotted neatly into the ribbon cable between the coin system and main board, allowing both old and new payment methods to work together. A simple fix, now rolled out to over 2,000 machines.

In-house electronics for small projects

Unlike other companies that outsource their PCB manufacturing, Winter & Smith designs and builds PCBs in-house.

  • Tailored to you – We can create custom PCBs specifically for your needs, ensuring that all components and connections are optimised for integration and long-term performance.

  • Higher quality – By controlling the entire production process, we ensure that every board meets high-quality standards

  • Faster problem solving – If an issue arises, we can quickly modify and produce updated PCBs without waiting for external suppliers, getting your systems back up and running
