A complex electronic product?
One engineer who owns all of it.
ProtoMakers develops hardware, firmware and software for defense, energy, agriculture and medical companies in Israel. You work directly with the engineer who designs the circuit and writes the code.
Everything a product needs to work, under one roof
Electronics development
Specification, component selection and circuit design: power supplies, high-power stages, sensors and RF.
PCB layout
Multi-layer boards, impedance control, Flex and Rigid-Flex, designed for EMC from the start.
Firmware & embedded
STM32, ESP32 and Nordic. Bare-metal and RTOS, bootloaders, over-the-air updates and real-time control.
AI in products and development
Edge AI running on the device, AI-assisted firmware development, and automated hardware tests with AI analysis.
IoT, server & mobile app
LoRa, cellular, BLE and Wi-Fi, plus the server and app that manage the devices.
Outsourced engineering
A senior engineer on your team: design reviews, rapid prototypes, or full ownership of a subsystem.
Production support
DFM, manufacturing files and BOM, assembly houses, production test jigs and certification prep.
Problems we solved
Many of our defense projects are under NDA and can be presented in a private meeting.
Multi-channel spot-welding controller
- 1500 A pulses with precise timing, using an array of 144 MOSFETs in parallel.
Ultrasonic medical nebulizer (Inhalimed)
- Piezo resonance tracking around 173.6 kHz, held within ±25 Hz while the part heats up.
Automated solar-panel cleaning
- Field cleaning units connected over LoRa to a central controller and a server.
Remote firmware updates over LoRa (PlasFit)
- Over-the-air updates for ~150 STM32 field units, with no hardware changes.
Main control board for a defense client (name confidential)
- STM32H5 at 250 MHz with three 2 Mbaud RS422 channels, all DMA-driven.
Power management board
- 56 V input, two protected PWM power stages and a CAN interface.
Fixed price per stage, no budget surprises
Every stage ends with something you can test. Only then do we move on.
Needs and constraints.
FreeRequirements, architecture, cost and timeline.
Working hardware and code, tested on the bench.
A small batch, field tests and fixes.
Manufacturing files, factory support, acceptance tests.
A small company for complex projects
ProtoMakers is led by Roman Alperovich, with over 15 years of combined electronics and software development. Based in Kiryat Tivon and working with companies across Israel. Winners of competitions by Calcalist, hub:raum, Fashion Fusion, Nokia and T-Mobile.
