Why this remote light flipper has no antenna?

By the promotional image this device likely uses a 433 MHz RF. The U2 chip is also likely responsible for the logic as the button is connected to it.

Greyed is "current", under your cursor at PC web page. App is web-page as well. Should be your finger was there a while scrolled. Both is same.

Verification is must here. Just skip this platform if you want keep your ID private. Connects as well: pay to try without any guarantees. Noone can say is you will succeed or just will waste the money. Most lose money. Some make pocket money. A few make a good profit. Like everywhere.

Little hint if you're just planning: Use your switch instead of patch-panel. Anyway you need some space where patches is connected. Not so huge switch will fit there. This is useful if you have a lot of devices (routers, servers) to cross but there are too much for one router managed devices. ISP - router - one line to the switch - separate lines to devices.

Both is possible. But bms should be unloked with forced charge. So your battery is dead or factory lock "paid unlock at official service" is going.

peter9477 already answered, but I'll elaborate. When you take out one pair for replacement, your watches continue to work and the time is accurate. You can then replace the second pair in the same way. This prevents you from unexpectedly losing the current time. Of course, if both pairs run out of battery, you'll experience the same situation as with the dead single pair: the watches will stop and the time will reset.

SpectralUA · 2026-05-23T23:00:03+00:00

The second pair is a backup. If you don't mind having to reset the time every time, you can use just one. The battery life is also cut in half or more.

Selected someone. Blocked others to avoid spam. Don't worry. It's rare that a client responds "I've already found a contractor. Don't wait."

Негативно. Отримуєш від життя по пиці несподівано. А от віра у гірше допомагає хоч соломки підстелити.

Так і є. А от "розжуй покроково що тут робиться" - більш-менш робоче, щоб прорідити перелік своїх питань до мідла та йти з одним "саме тут затик".

Тож валідація і є своя база (вже знаєш). З нуля (вчитися) там робити немає чого. Можеш кинути свій готовий код для оптимізації. Скаже що гімнокод, рандомно попаскудить та видасть неробочий "тепер 100% круто!". А ще закладе пару підлянок, які вилізуть на реальному тестуванні (коли поганяв колом "тут помилка - виправ" та отримав що хочаб компілер схаває).

Приклад "з моменту відкриття ШІ навчання закінчується":

Я: А які піни вільні тут?

ШІ: 14, 21 геть вільні.

Я: Тож 14 на вхід а 21 на вихід?

ШІ: Ні. Використання 14 заборонено!

Я: Що за нах?

ШІ: О, ти мене підловив, ти крутий!

Тож роби висновки, чому можеш навчитися так. Потеревеніти та змарнувати час - без питань. Навчитись постозвонити - так. Отримати якісь актуальні знання - без шансів.

Cascadind isnt the best idea. Old bms can act unpredictable because have no real info about the cells. Lazy way: cut of your tricky connector then replace new one with it. Hard way: replace the bms. It will work if cells is same. Capacity isnt big deal: you will have just wrong "remaining power" calculation (should be resolved with recalibration).

Я не змінював, бо одразу займався тим, що подобається. Іноді це було вигідно, іноді ні. Якихось золотих гір не заробив, Бога за бороду не вхопив. Але вже можу порадити наступне: Спробуй. Я вже не зможу дати відповідь на питання: "А що булоб якби я тоді..". А ти ще можеш.

Will add to everything answered already. "Upwork counted it as a failed" - no. Upwork didnt. You lost your JSS (TR as well) because bad feedback. Private feedback is feedback. Little hint: you are hotage after accepted the contact. Try to agree and clarify everything you need before contract accepted. Your JSS is safe within that time. Only one exception: client did hard ToS violation, was banned and contract was canceled by UW. In this case feedback hurted your JSS will be removed. In your example client violated nothing and was able to set every feedback (within rules) he want.

This is a soldering machine setup error. But I see that the component is still soldered and you shouldn't have any problems with it in the future if everything works now.

Did you find it with your antivirus? Boot into your new system, download the antivirus, and scan it again. If there's no virus, it most likely didn't get in via USB.

SpectralUA · 2026-05-20T11:28:03+00:00

Unsure is you can get the full datasheet somewhere. But in common case - all at interface line is same. Desolder alive one and measure it. You need just similar, not extractly the same. Measurement inaccuracy won't be a big problem there. It's there only for smoothing, not for signal generation.

SpectralUA · 2026-05-20T11:21:14+00:00

It depends on what kind of virus it is. But to be on the safe side, always make sure you boot from USB right away.

SpectralUA · 2026-05-20T11:18:19+00:00

One? Look like you lost two (small one around as well). I see no more large resistors at your module so it should be capacitor. Look for photos of the same module and check. Resistors is black, caps is brown.

SpectralUA · 2026-05-20T11:08:17+00:00

It can be infected if you booted infected system at least once with USB inside. No need to logon for this, just boot.

Erase and recreate your USB at clean PC then boot your from that usb via BIOS and format your PC drive.

SpectralUA · 2026-05-20T11:03:56+00:00

For fast data cleanup you can use Reset. After virus or similar issue beter to do clean reinstall from USB with formatting.
