Texas’ Right To Repair Bill Is A Signature Away From Becoming Law

June 9, 2025 by 21 Comments

In what could be a big step forward for consumer rights, the Texas Senate recently unanimously voted to pass HB 2963, which references the “Diagnosis, maintenance, and repair of certain digital electronic equipment”. If signed by the governor, this would make Texas the ninth US state to enact such a law, and the seventh pertaining to consumer electronics. Interestingly, this bill saw anti-parts pairing language added, which is something that got stripped from the Oregon bill.

Much like other Right to Repair bills, HB 2963 would require manufacturers to make spare parts, documentation and repair tools available to both consumers and independent repair shops. If signed, the act would take effect in September of 2026. Included in the bill are provisions to prevent overcharging for the provided parts and documentation.

As for how useful this is going to be for consumers, [Louis Rossmann] had a read of the bill and gave his  typically eloquent thoughts. The tl;dw is that while there is a lot of stuff to like, this bill leaves open potentially massive loopholes (e.g. assemblies vs parts), while also carving out massive exemptions, which leaves owners of game consoles, boats, cars, tractors, home appliances, etc. stranded with no new options.

Smart Thermostats Pitched For Texas Homes To Relieve Stressed Grid

November 14, 2024 by 86 Comments

It’s not much of a secret that Texas’ nearly completely isolated grid is in a bit of a pickle, with generating capacity often being handily outstripped during periods of extreme demand. In a latest bid to fight this problem, smart thermostats are being offered to customers, who will then participate in peak-shaving. The partnership between NRG Energy Inc., Renew Home LLC, and Alphabet Inc. will see about 650,000 of these thermostats distributed to customers.

For customers the incentive would be mostly financial, though the details on the potential cost savings seem scarce. The thermostats would be either a Vivint (an NRG company) or Google Nest branded one, which would be controlled via Google Cloud, allowing for thermostat settings to be changed to reduce the load on the grid. This is expected to save ‘300 MW’ in the first two years, though it’s not clear whether this means ‘continuously’, or intermittent like with a peaker natural gas plant.

Demand curtailment is not a new thing, with it being a big thing among commercial customers in South Korea, as we discussed within the topic of vehicle-to-grid energy storage. Depending on how it is implemented it can make a big difference, but it’ll remain to see how regular consumers take to the idea. It also provides more evidence for reducing grid load being a lot easier than adding grid-level storage, which is becoming an increasingly dire topic as more non-dispatchable solar and wind power is added to the grid.

When monitors around the world display a “Blue Screen of Death” and you know it’s probably your fault, it’s got to be a terrible, horrible, no good, very bad day at work. That’s likely the situation inside CrowdStrike this weekend, as engineers at the cybersecurity provider struggle to recover from an update rollout that went very, very badly indeed. The rollout, which affected enterprise-level Windows 10 and 11 hosts running their flagship Falcon Sensor product, resulted in machines going into a boot loop or just dropping into restore mode, leaving hapless millions to stare at the dreaded BSOD screen on everything from POS terminals to transit ticketing systems.

If you thought the global shortage of computer chips couldn’t get any worse, apparently you weren’t counting on 2021 looking back at 2020 and saying, “Hold my beer.” As if an impacted world waterway and fab fires weren’t enough to squeeze supply chains, now we learn that water restrictions could potentially impact chip production in Taiwan. The subtropical island usually counts on three or four typhoons a year to replenish its reservoirs, but 2020 saw no major typhoons in the region. This has plunged Taiwan into its worst drought since the mid-1960s, with water-use restrictions being enacted. These include a 15% reduction of supply to industrial users as well as shutting off the water entirely to non-industrial users for up to two days a week. So far, the restrictions haven’t directly impacted chip and display manufacturers, mostly because their fabs are located outside the drought zone. But for an industry where a single fab can use millions of gallons of water a day, it’s clearly time to start considering what happens if the drought worsens.

Speaking of the confluence of climate and technology, everyone problem remembers the disastrous Texas cold snap from last month, especially those who had to endure the wrath of the unusually brutal conditions in person. One such victim of the storm is Grady, everyone’s favorite YouTube civil engineer, who recently released a very good post-mortem on the engineering causes for the massive blackouts experienced after the cold snap. In the immediate aftermath of the event, we found it difficult to get anything approaching in-depth coverage on its engineering aspects — our coverage excepted, naturally — as so much of what we found was laden with political baggage. Grady does a commendable job of sticking to the facts as he goes over the engineering roots of the disaster and unpacks all the complexity of the infrastructure failures we witnessed. We really enjoyed his insights, and we wish him and all our friends in Texas the best of luck as they recover.

If you’re into the demoscene, chances are pretty good that you already know about the upcoming Revision 2021, the year’s big demoscene party. Like last year’s Revision, this will be a virtual gathering, but it seems like we’re all getting pretty used to that by now. The event is next weekend, so if you’ve got a cool demo, head over and register. Virtual or not, the bar was set pretty high last year, so there should be some interesting demos that come out of this year’s party.

Many of us suffer from the “good enough, move on” mode of project management, leaving our benches littered with breadboarded circuits that got far enough along to bore the hell out of us make a minimally useful contribution to the overall build. That’s why we love it when we get the chance to follow up on a build that has broken from that mode and progressed past the point where it originally caught our attention. A great example is Frank Olsen’s all-wood ribbon microphone. Of course, with magnets and an aluminum foil ribbon element needed, it wasn’t 100% wood, but it still was an interesting build when we first spied it, if a bit incomplete looking. Frank has fixed that in grand style by continuing the wood-construction theme that completes this all-wood replica of the iconic RCA Model 44 microphone. It looks fabulous and sounds fantastic; we can’t help but wonder how many times Frank glued his fingers together with all that CA adhesive, though.

Wind Turbines And Ice: How They’re Tailored For Specific Climates

March 1, 2021 by 75 Comments

Wind turbines are incredible pieces of technology, able to harvest wind energy and deliver it to the power grid without carbon emissions. Their constant development since the first one came online in 1939 mean that the number of megawatts produced per turbine continues to rise as price per megawatt-hour of wind energy continues to fall. Additionally, they can operate in almost any climate to reliably generate energy almost anywhere in the world from Canada to the North Atlantic to parts beyond. While the cold snap that plowed through the American South recently might seem to contradict this fact, in reality the loss of wind power during this weather event is partially a result of tradeoffs made during the design of these specific wind farms (and, of course, the specifics of how Texas operates its power grid, but that’s outside the scope of this article) rather than a failure of the technology itself.

First, building wind turbines on the scale of megawatts isn’t a one-size-fits-all solution. Purchasing a large turbine from a company like GE, Siemens, or Vestas is a lot like buying a car. A make and model are selected first, and then options are selected for these base models. For example, low but consistent wind speeds demand a larger blade that will rotate at a lower speed whereas areas with higher average wind speeds may be able to get by with smaller and less expensive blades for the same amount of energy production. Another common option for turbines is cold weather packages, which include things like heaters for the control systems, hydraulics, and power electronics, additional insulation in certain areas, and de-icing solutions especially for the turbine blades.

In a location like Texas that rarely sees cold temperatures for very long, it’s understandable that the cold weather packages might be omitted to save money during construction (although some smaller heaters are often included in critical areas to reduce condensation or humidity) but also to save on maintenance as well: every part in a wind turbine has to be maintained. Continuing the car analogy, it’s comparable to someone purchasing a vehicle in a cold climate that didn’t come equipped with air conditioning to save money up front, but also to avoid repair costs when the air conditioning eventually breaks. However, there are other side effects beyond cost to be considered when installing equipment that’s designed to improve a turbine’s operation in cold weather.

Let’s dig into the specifics of how wind turbine equipment is selected for a given wind farm.

Trouble With The Texas Power Grid As Cold Weather Boosts Demand, Knocks Out Generators

February 16, 2021 by 253 Comments

It comes as something of a shock that residents of the Lone Star State are suffering from rolling power blackouts in the face of an unusually severe winter. First off, winter in Texas? Second, isn’t it the summer heat waves that cause the rolling blackouts in that region?

Were you to mention Texas to a European, they’d maybe think of cowboys, oil, the hit TV show Dallas, and if they were European Hackaday readers, probably the semiconductor giant Texas Instruments. The only state of the USA with a secession clause also turns out to to have their own power grid independent of neighboring states.

Surely America is a place of such resourcefulness that this would be impossible, we cry as we watch from afar the red squares proliferating across the outage map. It turns out that for once the independent streak that we’re told defines Texas may be its undoing. We’re used to our European countries being tied into the rest of the continental grid, but because the Texan grid stands alone it’s unable to sip power from its neighbours in times of need.

Let’s dive into the mechanics of maintaining an electricity grid, with the unfortunate Texans for the moment standing in as the test subject.
