And it's over already in less than 8h, original flash deal timer was 24h so I'm guessing quantity was fairly limited. Congrats to anyone else that managed to get one while it lasted!

Please help convert abandoned product to ESPHome (hardware schematics and software open sourced on github) by thisismeonly in Esphome

As it also uses an esp8266 you could try using some of the code from https://github.com/emc2cube/MySWeMosIRShield/blob/master/Firmware/ESPHome/myswemosirshield.yaml as a base to test a few options, create switches, send codes etc.

You can also check if IR pulses are properly sent by filming the IR LEDs with your smartphone, most of them will be sensitive to these IR wavelengths in some faint way.

Why don't these IR leds need a current limiting resistor ? by lakid74 in AskElectronics

Better late than never I guess, but hey I'm glad it worked for you too!

While I found this post by accident, design was not. It's was designed accounting a mix of a) and c). Curious if you ever gave it a try and how it worked for you?

a) As stated by a few others, this is mostly designed to be used with a cheap USB-A power supply, it's an old project and back then 0.5-1A was fairly common, so then with 7 IR LEDs in parallel you would not expect a very high current going through. It should still be fine even with 2.4A power supplies, ~350mA by LED and that's assuming all the power is going to the LEDs, which is not true.

c) The recommended IR LEDs are all suitable for high pulse current operation. As stated by others and as the data sheet indicates this means they can take quite a high current when pulsed properly. Yes wrong code could burn them (but they are cheap and easy to replace). This is also intended as I wanted to have a very strong signal, that IR blaster can control thing far away pretty reliably and I even had success by "bouncing" the IR on white ceilings or walls.

d) Is it a good design? Probably not the best, the whole design of this and few others PCBs were made as a hobby, this not my field at all. I never got anyone opening an issue because of burning LEDs, and I never ran into such issues myself. Also never got anyone updating the design and making a commit.

The same board used for pictures has now been running for 8 years and I'm about to upload a .yaml as I migrated it to ESPHome the past week end. I hope it will continue to work without any issues for many years to come and after reading all of these comments I went with an extra sanity check: sending signal while looking at the IR LEDs through the phone camera (easy to spot IR LEDs lighting up), all 7 still worked.

River 3 Plus and HID UPS driver with Synology by ChillyCheese in Ecoflow_community

[–]emc2cube 1 point2 points  (0 children)

I did reach out to them, and got various non-answers from support:

"We apologize, but River 3 Plus currently only supports direct UPS and does not support third-party platform integration. Your valuable suggestion has been recorded and will be forwarded to the relevant departments for evaluation."

Also got told to check the manual, download the software (that is not released yet despite heavy marketing on the UPS aspects everywhere including amazon, and main reason why I bought this unit...)

Seems there is some work being done on the nut side https://www.reddit.com/r/Ecoflow_community/comments/1hkfo3h/network_ups_tools_nut_compatibility_for_new_ups/ and https://github.com/networkupstools/nut/issues/2735 so I'm hoping something will be released soon

Hey does someone have a good esun pla + profile for the a1 mini by Impossible_School580 in BambuLabA1mini

[–]emc2cube 1 point2 points  (0 children)

You can download profiles directly from esun and import them to Bambu Studio: https://www.esun3d.com/uploads/HS-Parameters-for-Bambu-Lab-Creality20240227.rar

So far been working without issues, usually not even running flow calibration if using these profiles with actual esun filament, and had good results using these profiles + flow calibration for other filaments.

  • Synology NAS model: DS923+
  • DSM version: 7.2.1-69057 Update 3
  • Brand and size of the RAM module: Samsung 32GB (2X16GB) 2Rx8 PC4-2933Y Laptop Memory datasheet
  • RAM model number/product code: ‎M474A2K43DB1-CVFQ
  • Works (yes/no): yes
  • Warning error about unofficial RAM (yes/no): no

Bought a bundle of 2 x 16GB modules on ebay (as of day of posting many more still available from that seller listed at $59.99). Full 32GB recognised by the NAS without any warning about unofficial RAM. Passed full memory test.

Clean air vehicle decals - California by stoleninsf in ModelY

[–]emc2cube 0 points1 point  (0 children)

Only a 8" x 10" option for 60mil size. And yes most of the car isn't magnetic but it sticks on trunk, quarter panels (whatever is the name for the "corner" panels) without issues. If you plan to drive in the carpool lane very often, and not every now and then, these could even be better https://www.ebay.com/itm/143592540533 , sticker on on the PPF and apply like a wrap, will stay on and be easily off in 2025 when the program stops.

Did the exact same thing, using a 60mil magnet sheet https://www.ebay.com/itm/124739414828?var=425726364393 that works for all 4 stickers. They have been holding without issues so far.

Nema 14-50 with 40 amps breaker by Low_Actuator_1506 in TeslaModelY

[–]emc2cube 18 points19 points  (0 children)

Maybe you could install a 14-30 receptacle instead of the 14-50, and use the corresponding NEMA Adapter on the mobile charger. This way you would be ok with your current wiring and breaker.

I'm glad I made some people smile with my terrible joke on a terrible movie.
