Alberta Premier Danielle Smith said in a year-end interview she's increasingly willing to use the notwithstanding clause.

The Bill 21 appeal is about the notwithstanding clause, Charter rights, and limits on government override — not provincial power

A site reliability engineer bought an abandoned eight-lane bowling center in a small Midwestern town for $105,000. The roof leaked, the electrical service was flaky, and the pinsetting machines were pushing 70 years old. Then came the real gut-punch: the quote to replace the 2008-era scoring system landed at $120,000, more than the building itself had cost. Rather than sign that invoice, the engineer, known online as "section33," rebuilt the whole thing from commodity parts for about $1,600. The project, called OpenLaneLink, brings a lane pair online for roughly $200, or around $400 with extra features. That is a rounding error next to a six-figure proprietary contract. ### What section33 actually built A modern scoring system does far more than tally strikes. It clocks ball speed, tracks trajectory, runs camera-based pin detection, watches the foul line, drives the pinsetters and ball returns, and paints the animations bowlers stare at between frames. As section33 pointed out, most of that expensive electronics ends up firing a relay bolted to 70-year-old mechanical gear. So the replacement leans on cheap boards doing exactly that job, and nothing fancier. ### How the hardware fits together Each lane node runs on an ESP32. The nodes talk over an ESP-NOW star-topology mesh, with a wired RS485 fallback for the electrically noisy back-of-house where motors and relays throw interference. Every node reads its sensors, switches its relays, and reports events up to a Raspberry Pi acting as the lane computer. On the Pi, Redis streams the events and a React frontend serves the scoring screen over WebSockets, so an owner can restyle animations without begging a vendor for permission. ### The takeaway for student builders This is a textbook lesson in reading a spec sheet with a skeptic's eye. A $120,000 box turned out to be an ESP32, some relays, and a Pi wearing an expensive badge. OpenLaneLink is slated to ship as open source hardware, firmware, and software, so you can study the schematics and the ESP-NOW code directly. Read the full write-up at Hackster, then think about what other overpriced "black box" in your school lab is really just a microcontroller and a handful of GPIO pins waiting to be understood. _Originally published on blog.circuit.rocks._ # esp32 #esp8266 #iot #wifi #circuitrocks

After buying an abandoned 8-lane bowling center, HN user section33 found that replacing the six-figure scoring system would cost $80k to $120k, with parts running $4,000 per lane pair. Since the 70-year-old bowling machines are almost entirely mechanical and the “advanced” system was largely just firing a single relay to trigger the pinsetter, he built […]
