Some EV models have gone back to drum brakes. The main drawback of drum brakes is overheating, which is why they can’t be used for performance vehicles, even though drum brakes can deliver more braking power. EVs with strong regenerative braking reduces pressure on the brakes, making the heat build-up less of a problem.
The main advantage of this is cost, not weight or performance, but it does show that EVs have different profile to ICE cars.
It's simple power vs energy equations. Let's say you need to supply steady 1MW to town for 1hr, 2hr or 10hr. This needs total of 1MWh 2Mwh or 10Mwh respectively. Let's say battery would cost $200/kwh, then this would cost 200k, 400k or 2M resp. Battery storage is generally used for less than 2hr duration currently where they are price competitive. For the rest, either gas peaker, coal or hydro is used.
Also, when you’re done with the solar farm you simply take the panels off, disassemble the aluminium frame, then you have your field back. Unlike a coal mine.
This guide to the UK’s Land Use Framework says that the amount of land required for renewables by 2050 is comparable to the amount of land used by golf courses.
Perhaps they did not mean point 18, but I found it interesting anyway.
The existing gas infrastructure represents a large amount of taxpayer investment, not due to be paid off until 2070. But it’s estimated that there won’t be any users of that infrastructure beyond 2050.
The good reason is that there are plenty of third party boards that already offer what you want. There’s very little to be gained by an ‘official’ one. The next one probably should have C, if just because it is the Euro standard, but no urgent need to backport.
I don't need a Pico or any other 3rd party board. I drop SC-1511/12s packages on my PCBs as needed.
What I am saying is that the reference board for an RP2350 should have a USB-C port in 2026. It's not aesthetics or even convenience (and it's definitely not price) so much as establishing best practices for how a part should be used.
A big part of that is to acknowledge the context in which a part exists, and in this case, it's both a fact and a very good thing that the world has embraced USB-C. It's even being regulated in many cases.
I'm not saying that you can't smoke, just that maybe you shouldn't do it when you're volunteering as a Big Brother.
I know this is likely to do with the nature of the problem, but that hasn’t stopped us from getting some wildly-unsuitable decentralised nonsense in the past.
It is hard to replace the old thing with another old thing. Search engine is already a fine tuned business, new comers will have hard time in it, no matter their tech stack.
It's like trying to raise better horses, while the other side has already built a empire on that and weaponized it.
The way out of here is to find something better than search engine, just like how cars replaced horses. But it's the same reason Google Search is replacing itself with AI too, they're already trying to replace their horses with cars.
Esp32s are amazing fun. I designed boards in the 80s and I still love tinkering with microcontrollers. The reflux control for my still currently uses a brushed motor controlled by PWM and I am upgrading it to a second hand pump with a brushless motor so I am looking at driving it. I just set up an old drone ESC and am controlling the motor with dshot and it works ok. There is a little pre built board Simple FOC that is also esp32 I just ordered for 20 bucks to give a try.
I've been a developer for 45 years and I still actually like it most days.
I recently learned of ESP32-P4 that has graphics compositing optimizations.
A couple of years ago, I used an RP2040 to build a graphics card with 2D triangle filling and other pretty nice abstractions.
Next time... It'll be the ESP32-P4. Somewhat looking forward to that project, but there are prerequisites that need to be dealt with first. Yes, I'm very grown up. It sucks. :)
agreed, I think much of the appeal for me is the physical element of wiring things up and seeing it do something more than changing a few pixels on my screen.
How you know me so well. I also like how cheap all of the parts and pieces are. It's like the next step after Legos. Although, they have way more interesting Legos today than what I had as a kid. I've bought components with an a specific project in mind, but once it's built I find myself taking them apart and making a new something with it combined with other parts I have lying around. Things are cheap enough that I don't mind so much if I got something wrong and release a little magic smoke.
Yes exactly! I still can't believe how cheap an ESP32 is - a device with bluetooth, WiFi, and ample processing power and RAM for most tasks you'd use an MCU for. And yeah I love finding out I already have all the parts I need. Now, keeping them organized, that can be a struggle. I have a couple of these double sided tool organizers [1] and a tackle box, but sometimes I'm still digging through bins to find a part I know I have but can't find
