Microcontrollers
Small boards that turn a handful of parts into something that senses, decides, and acts. Evaluated on cost, toolchain pain, and how far a beginner gets before hitting a wall.

evaluation labs
Evaluating today's digital technology for the little guy.
Technology Areas
Beginner Python
An approachable first language with readable syntax and immediate feedback. Evaluated as a starting point for people automating their own work rather than looking for a job.
Read the notesDigital Amateur Radio
Traditional transceivers paired with computer software to send data, images, and text instead of voice. Evaluated on what a modest antenna and low power can genuinely reach.
Read the notesHome Assistant
An open-source hub that pulls mismatched smart devices into one local dashboard. Evaluated on privacy, reliability when the internet drops, and how much upkeep it really demands.
Read the notesThe Premise
Nothing here is certified, sponsored, or shipped in a review unit. Every board, radio, and script written about on this site was bought at retail, wired up on a single desk, and run until it either did the job or did not.
The audience is the person working alone: a hobbyist with a soldering iron, a new licensee with one antenna, someone teaching themselves to program at the kitchen table. The measure is always the same — can one person get this working in an evening, and is it worth the money.
How Things Get Evaluated
Start from zero
Every evaluation begins with an unopened box and stock documentation. No prior configuration, no borrowed setup files, no expert shortcuts that a first-time buyer would never find.
Run it on a real bench
Boards get wired, radios get keyed, integrations get left running for weeks. Problems that only show up on day nine are the ones worth writing down.
Say what it cost
Time, money, and frustration are all reported. A cheap board that eats a weekend of driver trouble is not cheap, and that gets stated plainly.
The Bench
Modest equipment on purpose. If a result needs a lab-grade instrument to reproduce, it is not a result the reader can use.
- Bench multimeter
- Continuity, current draw, and the sanity check before power goes on.
- Logic analyzer
- Reading I2C, SPI, and UART traffic when a datasheet and reality disagree.
- Adjustable supply
- Current-limited power so a wiring mistake costs nothing but time.
- Temperature-controlled iron
- Headers, antenna connectors, and the occasional rescued trace.
Where To Start
Each technology area has its own page: what the hardware or software actually does, what it costs to get going, and where the rough edges are.
