Water is being used to get heat from one place to another. The idea is being able to separate the heat generation and the heat extraction
Nope, it doesn't have to be open loop! Example of such a system being used specifically for datacenters: https://blog.vantage-dc.com/2026/04/22/cooling-without-the-d... Evaporated water is condensed, and in the process…
Evaporative cooling does not necessitate an open loop system

I usually smell it too. I've noticed its when they switch from the air handler provided by the jetway (big yellow hose) to the plane's onboard system. Perhaps there's some sequencing procedure that the staff is moving…
You're right, I was representing a best-case scenario with an intention to be inspiring. And yes, the Android approach works too and I have done exactly that with Claude previously. The BLE dongle is however a…
Quite possible transport is encrypted, but that can likely be overcome with some RE on the Android app. Given the price of this piece of hardware, it's likely recoverable with moderate effort. At least worth a try.
While I empathize with your feelings about lock-in, I encourage you to see that we live in an amazingly empowering era. I would wager that with $20 in credits for the LLM flavor of the week and and an equally expensive…
The 8266 has no flash readout protection, and the UART is exposed on a programming header. It was very easy to dump the firmware.
I looked into it and the channel sounding approach isn't yet ready. Will need the new iOS as well as some firmware work from Nordic's side.
I am planning a write up once I get it working. I'd be happy to share. My setup is a logic analyzer tap on the SPI bus between 8266 and the RFM69 on the bridge device to log raw traffic, and my secondary RX (ESP32 +…
Nordic has newly-released silicon that supports Aliro using Channel Sounding, meaning a UWB chipset becomes optional. Also, NFC is supported directly. https://www.nordicsemi.com/Products/Technologies/Aliro/Produ...
This is cool! I have recently been building a "life admin" system that is focused around keeping track of bills and insurance reimbursements, and I am currently extending it to support a recipe database. My data model…
In simple terms, this works by doing an XOR on the outputs and if they disagree, performing a fault recovery. There's also space systems that use 3 processors and a majority vote for the correct output, but that's…
It's not about the whole microcontroller having less than 64kB of memory - it's that each WASM module has a minimum memory size of 64kB, regardless of how much it actually requires. Also, if you need 65kB of memory, you…
I use this app on all my Macbooks — it's great!
I've always wanted a Shaper Origin, but the cost and subscription fee required for accessing some features always turned me off. I don't need it for anything other than fun hobby projects and couldn't justify it. Now I…
I spent a LOT of time on this website as a 90's kid. One of many that inspired me to get an EE degree. Projects like this always felt like some incredible magic, and came with an artistic aesthetic that I find…
On your note about capacitor sizes — at my first EE job, my boss taught me about capacitance-voltage derating[0] for ceramic capacitors and it was quite the revelation. There is a significant inverse relationship…
I live in Alameda and this place is such a local gem. The owners are really genuine people too. Great place to spend some time! They also own a whole warehouse out at Alameda Point filled with machines. I know they have…
As a former Fit owner, I wish I had thought of this! The AC was really bad. We did a lot of road trips and it really struggled out on the long desert highway stretches.
Just op-amps and FETs for the active components. The design from my memory was: - To get position, 2 integrators were applied to an adjustable voltage representing gravity. - The FETs were used to set initial states of…
That's really interesting. For me, I very much do NOT enjoy the taste of truffles in restaurant dishes because it's often so overbearing. I just don't find the flavor interesting, and it's very singular. Perhaps I would…
This is a great resource for why Starship is groundbreaking. So much so, it’s not even really comprehensive to the existing space-industrial complex. https://caseyhandmer.wordpress.com/2021/10/28/starship-is-st...
