- Comment on Microcontroller recommendations for a weather station 5 days ago:
All fair points, assuming you write all your code yourself. But WiFi is still a pig even with optimization, coin cell is impossible which is what he/she asked to use.
- Comment on Microcontroller recommendations for a weather station 5 days ago:
If you want this to be powered by a coincell battery or any battery you need to figure out a power budget and pick a wireless protocol. WiFi is incredibly power hungry and won’t happen with a battery unless you like charging it every few days. If you are willing to make it a powered setup it will open many options otherwise youre stuck with zwave, ZigBee, BLE and LoRA. If you want to mix this project with other fun stuff like LoRa/meshtastic look into these. They snap into a main board and you can add a temp and humidity sensor and collect the data over BLE, add a screen and communicate over LoRa for miles. I can get these to run on a 18650 battery for about 3 weeks.

Esp32 will demolish a full sized battery, never mind a coincell.
- Comment on Why do some Americans "feel ashamed" for being American even when it's not their fault? 2 weeks ago:
I feel similarly and to expand a bit its more the fact that second time around electing this fool proves that that majority of Americans are either horrible people or useful idiots which is incredibly depressing to know with certainty. For me, first time around was a fluke, second time is reality. I’m exploring citizenship elsewhere as a backup plan.
- Comment on Bad experience on selfhosting nextcloud 4 weeks ago:
My install is bare metal, all SSS, redis and php-fpm optimization and I’m extremely happy with the performance. Also use transcoding from an Intel a380 and use Memories for the whole family. Works snappy and flawless. You need to tweak the php settings.

- Comment on How would I make a HVAC simulator to see what a thermostat would do if the indoor temp was 400°F 4 weeks ago:
Everyone is over thinking the hell out of this. Almost all thermostats use a cheap NTC resistor, just change the resistance so the hardware thinks its at the whacky temperature. Or you could figure out the bias voltage the system uses through the NTC then apply your own external voltage to trick the system.
- Comment on Looking for a selfhostable chat service that people on phone and computers can log onto 4 weeks ago:
I bailed on rocketchat a few years ago for Mattermost and never looked back. Rocketchats update cycle was insane, sometimes two releases in a week but often several a month. A few pdates required full database dumps and manual tweaking. It just wasn’t for me.

- Comment on Is it insane to run a home server on an old laptop instead of a Raspberry Pi for self-hosting - what do I need to worry about? 5 weeks ago:
My primary server uses to be a 12 year old laptop with an SSD. I deployed a laptop server in rural Greece and its bulletproof, it VPNs back home to the US and works during short power outtages. Only caveat is the CPU fan, if you run the server with a high load the fans are not designed for years of high usage. I got crazy enough with one server where I cut the bottom out and mounted a large aluminum plate to the CPU heatsink and made it passively cooled.

Attatch a sausage to a soneloid and make a capacitive button pusher!
- Comment on 18650 battery pack 16s2p design 1 month ago:
Way better to use your old junk. I like that youre make your own home battery, ive considered it. I have solar installed and would love to not consume grid power at night. I’m thinking of installing a bank of lead acid batteries under my ground mount solar that would dump power into my home at night.
- Comment on 18650 battery pack 16s2p design 1 month ago:
May I ask why 18650? 21700 have better energy density and theyre easier to get these days. The price has also come down a lot.
- Comment on It's interesting that we have multiple appliances in the kitchen who's sole job is to turn electricity into heat. 2 months ago:
That’s silly, they really don’t use much power in the grand scheme of things. It uses a lot of power for a very short period, a small blip. Big power consumption comes from things that run often or all the time. It compounds.

Does anyone remember older 747 jets having these types of projectors to show movies on international flights? Always thought it was so cool.
- Comment on 2 months ago:
Thank you for putting into words what ive subconsciously been thinking for years. Every search result prioritizes videos at the top and I’m still annoyed every time. Or even worst I have to hunt through a 10 minute video for the 30 seconds of info I needed. Stoohhhhpppp internet of new! Make it good again!
- Comment on US | White House tries to tamp down corporate panic for high-skill visa holders after last-minute overhaul 2 months ago:
Tax the offshore engineering and R&D, too. My company plays both these cards with a China office to hire local, cheaper talent plus manufacturing is local so they help domestically on their side. Thats a win. Then they hire tons of Indian H1B for engineering in America.

- Comment on USB PD for older device 3 months ago:
You can also buy ‘trigger boards’ and wire it uo yourself if you like. I replaced all my barrel jack devices with USB.
- Comment on USB PD for older device 3 months ago:
That is not correct, you won’t get a random lower voltage. You are correct that thw PD supply needs to support the voltage but PD always starts with 5V for backwards comparability then digitally its negotiates the PD voltage it wants, if it asks for 12v and its not available it with just stay at 5V. It won’t spit out the closest value unless the device asks for it. Its a very strict and wonderful standard.
- Comment on Help diagnosing server freeze issue 3 months ago:
Check the power supply too. Those mini PCs just use a cheap laptop power brick and sometimes they can’t sustain their full output anymore. I had one server constantly crash and once I swapped the power brick I never had a problem again.
- Comment on Acquired a sliding mitre saw 3 months ago:
When cutting aluminum, push very gently. And when the raw material gets too small, don’t try cutting the last little piece. Small working material will increase the chance of accidents. I set my limit around 20 cm.
This. So much this. Even when cutting wood properly on a mitre be careful with little pieces. You simply cannot control or hold really small pieces. Almost lost some fingers and scaring the hell out of myself making that mistake.

Cool and dark, he would just toss them in baskets in a dark space that didn’t even stay that cool. He might have picked them before they were ripe but I dont remember.
- Comment on What would be ancient ways to properly store vitamin C? 3 months ago:
Lemons if stored correctly will last 10 months. My grand father would just toss them in a dark storage room in Greece and they lasted until the next harvest.
- Comment on Acquired a sliding mitre saw 3 months ago:
I think you can get away with it for aluminum, but just be cautious and slow knowing its not the ideal tool. I’m sure it will work through since its such a soft metal. Just listen to the motor in case it protests your feed rate.
- Comment on Acquired a sliding mitre saw 3 months ago:
That looks like a mitre saw, but you mentioned you want to cut aluminum. Be careful, I believe mitre saws are for wood only and spin much faster than a chop saw which is designed for metal and spins slower.
- Comment on Google Assistant Is Basically on Life Support and Things Just Got Worse 4 months ago:
I work for an un-named company that makes stuff that has google assistant on them. Initially we out hardware mutes and pipes the microphones to physical hardware that monitored for wake up words and would then start piping the microphone data to the mother ship. Google told us to stop that, only way to certify the product as compatible with Google Assistant was to pipe the raw microphone data to the mother ship 24/7. That was 5 years ago and I removed all devices from my house.
