ESP32 VROOM disconnects immediately after connecting with bluetooth
2024.11.25 21:56 Butterspaceflight ESP32 VROOM disconnects immediately after connecting with bluetooth
I want to send signal from an accelerometer, trough esp32 to my computer wirelessly to make a midi instrument from movement, and when it connects with bluetooth, it disconnects right away, what can I do? Thank you!

2024.11.25 21:56 Swimming-Carry2268 Get $75 off AT&T with a Refer-a-Friend promo code (I made a site with an active code!) 🙌
Hey everyone! 👋
When I was signing up for AT&T, I really wanted to use the $75 Refer-a-Friend promo, but finding a working code was such a pain. Most of the links I found were either expired or just straight-up didn’t work.
So, I decided to make my own site to fix that! It’s called attpromocode.com, and it has active Refer-a-Friend promo code that actually works for "AT&T Wireless" and "AT&T Fiber". No more wasting hours hunting around like I did!
If you’re signing up for AT&T, this should make it super easy to get the $75 discount. Hope it saves you some time and money! Let me know if it works for you—I’d love to hear about it.

2024.11.25 21:56 Ill_Advantage361 Oh the burnout
I am finding it so hard to stay motivated. I don't know if it's burnout or....what? I've been in this role 7 months. I had zero training, it's a new role. I really don't know what i'm doing. My boss is a great lady but a total go-getter. I don't think she ever takes a break. She's responsive if I say I need clarification etc...but she has me pivot constantly and I don't think she remembers if she told me about the pivot. Just invites me to these random meetings where i'm like.....what am I doing here. She has her hand in SO many pots and wants me there with her. it's like there is so much to do I don't know where to start, so I just don't.

2024.11.25 21:56 MrTenacious30 34[M4F] New York/Nearby PA- Home after a long day at work.. looking for someone to enjoy some of my free time with..
Another year survived. Hoping I can spend this next year living, rather than just surviving. Having someone like-minded to spend some of free time and share deep thoughts with sounds fun. Enjoying the exploration of each other's minds, as much as we enjoy exploring each other's bodies..
When I'm not messing around with my music I enjoy a wee bit of gaming and watching something with a bit of dark humor in it.Daily enjoyer of bush burning because it helps me deal with the how lousy life can be, and it helps with my creativity. Not like its a necessity, but its something I embrace my enjoyment of. Prefer it to sipping spirits at a bar, although with the right person that could be fun to do again too.
Maybe those are topics of discussion we could start with if you're interested. Or we could talk about why pumpkin spice isn't the highlight of the fall season like the commercial world makes it out to be. Discuss why we are looking forward to, or dreading, the upcoming holidays.. Hopefully you enjoy a sprinkle, if not a soaking, of sarcasm mixed into the conversation. It's one of my preferred brands of humor..
Physically-5'9, blue eyed, fairly fit, and pale white because I only enjoy dwelling in the darkness of the night..
Send a pic in your message if you like what you read and I'll send one back. If we both like what we see maybe that means the conversation will carry on longer than a day.
But, yeah.. If you want details I trust you're capable of figuring out more. I mean, you got this far. Right? 🤷🕺

2024.11.25 21:56 Ok_Channel_7923 Manifested Love/ Sp
So i was trying to manifest my ex boyfriend for months since he broke up w me in april this year. actually he is a toxic person but i manifested that he is obsessed with me and that he would change completely because he never listened to me, he never took me seriously, did not know how a relationship works and he’s an idiot tbh never thinks before saying something. I manifested with affirmations but mostly with the the law of assumption. I acted like i am his wife and imagined how he texted me obsessive messages. First it was going to a right direction he invited me to the cinema etc. but then suddenly he was quite and did not text me anymore. Randomly he called me at 1 am and he was crying, so he told me he had an affair with his BEST FRIENDS GIRLFRIEND (so the girlfriend basically cheated and yea he had something with her) so i sum it up after that it got worse and worse, i found out that he is the worst person and the biggest liar, but i chose that i still manifest him (dumb right ?) in those months i always saw the number 111 and now i know what it meant for me. So there was a Halloween party and my ex was there AND someone special… I met this special boy on 31 October and really talked and connected with him until the night so on the 1st nov (that explains the 111= 1.11) this person was everything i ever wanted. He listened to me, he is heart warming etc. he also said he felt a connection instantly. After 1 week still manifesting my ex even tho i met this beautiful person, i found the out that my ex is like the worst person and cheated on me and actually still lied to me all the time. So i said it’s enough i never deserved that At the same moment this special boy I met on the Halloween party texted me and omg he is perfect, he is everything I ever wanted, he is completely obsessed with me and I’m just the happiest. I blocked my ex and deleted him and I have zero feelings for him. This boy and I are not in a relationship YET but we are going to because we already kissed and had dates etc. and he is very obsessed with me just perfect… What I want to let you know: sometimes the universe gives you something better than that just trust the process, I was never happier

2024.11.25 21:56 Friendly_Wack LV loom connectors discussion
Hi everyone,
I’m looking for recommendations and insights into your experiences with various LV connectors.
While I think we can all agree that having connectors on your wiring looms is a huge benefit, mil-spec connectors are often prohibitively expensive. Brands like Souriau, Deutsch, Fischer, and LEMO are top-tier options, but their price range is extremely difficult to justify.
Browsing through Mouser, RS etc., you’ll find literally hundreds of thousands of options, which makes narrowing down good alternatives quite hard.
That’s why I’m reaching out to ask: what connectors have your teams used, and what were your experiences with them? Were they worth the investment? How well did they hold up over time? What advantages or disadvantages did you notice?
(Just to clarify, these connectors will primarily be used to quickly disconnect devices from the car for inspection or maintenance.)
Thanks in advance for your input!

2024.11.25 21:56 teacoffeecats How do you guys “advocate” for yourselves?
Advocate is in quotations cos I’m quoting my teacher training provider who say I have to start advocating for myself.
If I’m honest I’m not used to it at all like I genuinely don’t know where to begin I know it might sound stupid but I’m being so serious. Like usually when I notice I’ve had an additional need, if there hasn’t been accommodations for me I’ve just found a way to make it work for myself and I thought this was a good thing because it’s made me good at problem solving but at the same time it would just be easier if I was open and upfront about my condition but that’s really hard for me because I struggle to ask for help because I’m used to dealing with everything by myself and plus my household/culture isn’t the most understanding about my CP. Like my family understand certain physical needs I have but it’s limited to just that. They don’t understand the cognitive affects of CP or that CP is brain damage.
Can anyone here help me?

Ciao, sto valutando un'offerta di lavoro che mi porterebbe a trasferirmi dal Sud-Est ad Udine.
Mi consigliereste di trovare casa in affitto ad Udine o nei paesi/comuni vicini (l'ufficio sarebbe a Buttrio)?
Com'è in media il costo della vita? Come sono le città e Udine, dal punto di vista della vita nel quotidiano?
Grazie.

2024.11.25 21:56 Weirdskinnyguy Starting point for developing, scanning and printing
Hey everyone, I'm new to this community and it's awesome. I'm looking for advice relating to the title. Some context:
I recently picked up my first film camera, a Yashica Electro 35 ($12USD with original flash and filters!), and found a battery adaptor to power the light meter, LED indicators and subsequent shutter speed. I've shot a couple of pretty nice rolls (400 color plus) and had them developed and scanned professionally with pleasing results.
I'm moving to a pretty remote country in Asia soon, with an easy connection to Bangkok. I'm not militant about anything beyond the quality of my Yashica just yet (the bit of fungus on the lens gives it character) but I'd like to establish a rudimentary dark room set-up to begin developing, scanning and printing my own photos.
I understand it is probably a common question, and I've done a fair bit of poking around and googling myself, but if anybody has a moment to post a few links below that would be really helpful.
I'm looking for:
- Quality, sequenced online tutorials
- Beginner tips from those of you who have been in my shoes
- Perhaps there's a go-to place in Bangkok that would be helpful with items I need to purchase locally, like chemicals
- Any blindspots I have!
Thank you so much for the inspiration and the community support!
