Capabilities
From sensor to cloud.
We work across the complete connected-device stack: the electronics, the firmware, the radios, the measurement chain, the cloud that receives the data, and the test fixtures that get it out the factory door. One team owns the whole problem.
Embedded Systems
Firmware, RTOS development, drivers, low-power optimization, BLE, cellular, Wi-Fi, and device communications.
Wireless & RF
BLE, LPWAN, LTE-M, NB-IoT, Wi-Fi, satellite connectivity, antennas, RF architecture, and range optimization.
Sensors & Edge Intelligence
Measurement systems, signal processing, calibration, edge processing, anomaly detection, and intelligent sensing.
IoT & Cloud
Device-to-cloud architecture, APIs, telemetry pipelines, provisioning, dashboards, alerts, and fleet management.
Production Engineering
EVT/DVT support, automated testing, fixtures, manufacturing validation, provisioning, and scaling from prototypes into production.
Where We Work
Built for difficult environments.
Most of what we build has to be inexpensive, power-efficient, wireless, and remotely deployed, then left alone. A device in a grain bin, a reefer trailer, or a field station can't be rebooted by hand, so we design for the constraints that show up after installation: battery budgets measured in years, intermittent connectivity, temperature swings, dust, water, and people who aren't engineers.
That shapes every decision, from radio selection and sleep-mode design to enclosure sealing and how a fleet reports that something has gone wrong.

How We Work
Engineering without the handoffs.
Bring us an early concept, an existing design that needs fixing, or a prototype that needs to become a manufacturable product. The same engineers who choose the radio and write the firmware are the ones standing at the test fixture, so decisions made in week one still make sense on the production line.

Experience
Built by engineers who have shipped real products.
General Resistance, LLC is an embedded, wireless, and IoT engineering firm led by Brett Byer, an embedded and hardware engineer with more than a decade of experience developing wireless products, instrumentation, and IoT systems.
His work has ranged from consumer electronics and laboratory instrumentation to humanitarian early-warning systems deployed in some of the world's most challenging environments.
Track record
10+ years taking connected products from first prototype through production.
Prior hardware work
Sonos, Elemental Machines, and Hala Systems.
Recognition
Technology Brett worked on is permanently represented at the Smithsonian National Air and Space Museum.
Awards
2023 HardTech Award (formerly the Misties) for IoT innovation.
Depth across the stack
Low-power wireless, BLE, cellular, satellite, RF, sensors, firmware, cloud infrastructure, manufacturing, validation, and production test.
Products
What we build for ourselves.
Alongside client engagements, General Resistance, LLC designs, ships, and supports its own connected-hardware products end to end — including the text-message programs that come with them.
LoadoutGuard
loadoutguard.comTool and equipment tracking for work trucks. When a crew pulls out without something, LoadoutGuard texts the crew lead within minutes — while they're still close enough to turn around.
General Resistance, LLC operates LoadoutGuard's SMS alerts program, "LoadoutGuard Alerts."
ChickenScale
chickenscale.comFeed-bin monitoring for poultry farms: live bin weight, days-to-empty forecasts, and refill alerts, all delivered as simply as a text message.
Start a Project
Tell us about the hard part.
The battery life that isn't adding up, the radio that drops out in the field, the prototype that can't be built at volume. Send a short description of what you're building and where it needs to work, and we'll tell you honestly how we'd approach it.
Typical engagements: feasibility studies, full product development, design rescue, production readiness.
