My rca rpj 133 overheated due to dust, I took it apart and cleaned really good. However my fresnel lens closest yo the led light melted. I need a replacement. Does any one know where I can buy one. Rca was no help. The demensions are 11cm by 60cm all I can find on Amazon or anywhere are 14 x 90.

Hey y'all, I'm the kind of person who will pick up furniture and electric goods from the street that people have thrown out. Sometimes it's beyond repair, sometimes it just needs an easy repair, but most of the time it works without needing repair.

As such, I have accumulated 4 TVs (LCDs). All roughly around the same size (between 28-32"), and all working. My plan is to build an enclosure that looks like a window, take the screens and circuit boards etc out of the TVs, and combine them together within the enclosure, running in tandem, so I can then have different scenery videos/animations playing on them. Sorta like in Back to the Future (if you're old enough to remember the film like me).

I'm okay at electronics, but more importantly I'm even better at following instructions. I'm good with woodworking, so the enclosure shouldn't be an issue, but I guess I'm looking for advice on how to get all the screens out of their current TVs, joined them all to work together, figure out how to power them all with a single power cord (not sure if I can use a single power supply inside the enclosure to power all four, and if so, how to calculate the power I'd need), and finally how to have one HDMI input split up and go into all four TVs to provide the video/image.

I am happy for any and all feedback, suggestions, critiques etc. So please, if anyone has any ideas, I'm open to anything.

Thanks for reading 🙂

I got this console, but I can't access anything. Also, I am a beginner so I don't really understand any of the tech words. Please help me out!

Is Handbrake with VLC LIBDVDCSS still the best option?

***** thank you all found an alternative Winx works great ****

Is it possible to do anything cool with old vape batteries? Like maybe a portable battery pack? My first worry would be all the voltage and manufacturing too be unreliable?

Acuity or Calendly?

New to automation but looking to try!

I’m trying to power a 120v device and create a system to get it to turn on for 30-90 seconds then turn off for another 30-90 seconds.

I was thinking at first to use a smart outlet or power strip but most of them are meant to turn on and off at certain hours of the day or days of the week and not necessarily for intermittent power.

What would be the easiest way to try to automate something like this?

P.s. This is an outdoor project and unfortunately I don’t have access WiFi. I thought about using one of my raspberry pi’s but it may take too long for me to try to program something (with my very limited knowledge) where I could just use something off the shelf. I will have my phone with me whenever I’m operating it so maybe I could use something Bluetooth enabled and figure out an IOS automation to run it. Any ideas? Any help is much appreciated.

Is there a way to change de default pre-recorded voice like "pairing", "connected", etc, from earphone bluetooth?
The recorded female voice is really something horrible, with a tone that makes me cringe a lot every time I connect my earphones.
The constructor is Force Play, I don't know much about them, and I'm totally new to this reddit.
Thanks a lot!

I need help on design the circuit and to calculate the voltage output for tazer gautlets like the ones from batman origins. Can anyone help me?

I have a Vodafone Curve gps tracker that no longer works because Vodafone have stopped servicing these gps trackers. Their app that was used for it no longer works at all. Is there any way I could connect it to any random gps tracking app that cheap gps trackers use (the type you can get on AliExpress)

I think the main issue is that the description of the Vodafone curve mentioned it has a SIM card installed into the device. Not sure if it’s the type of thing that can be removed and replaced with another sim to get it working with the random gps tracker app. Any advice on how to solve this or suggesting another subreddit that could guide me better would be much appreciated! Thanks

My idea is to attach a deattachable thin steel disc, so i can attach or deattach it off my bike whenever i want, then on the disc will be conncted a thicker disc with a hole in the middle with a simple motor (likely from a strong fan or other device) in the hole, this will be attached on the chainrings.
On the frame, will be attach a deattachable battery holder.
On the handle, a small simple switched kept on the handle with a rubber belt.

And optionally, i want to create to it a bar which on the both sides, has the footpegs, which are again deattachable, which is a bit further away of the chainrings, a case where i put the footpegs bar, a honk, and a signaling system on both sides with a headlight on the rear and brake light on the back, which will have it's on system to turn on the headlights and signals, which will be powered up by another battery holder with bigger batteries.

I also have two more ideas to make my bike into a e-bike or motorbike, but one is not fully thinked of, and the other one surely will not work.
(btw sorry i have some spelling errors)

Help creating a dust free space

Does anyone have any tips for creating a dust free space? I'm trying to apply screen protectors to some things but I can't do the shower method for the life of me. There is always a spec or two of hair that ends up under it. I'd like to just have a work space I can dust proof in a fool proof manner.

i'm thinking of building a laptop cooling pad with a strong fan and a foam seal around the edge so that air can flow through the case. I was wondering if a fan that is too strong can damage the built-in fans if the airflow makes them run even faster. i think i might be overthinking this, especially if there are coolers like this for sale, but i would like to know if there is a limit for this (and if there might be other problems). Thanks for the help

Hello. For some background I use the H10-76 for work and can’t really use anything else. I’m looking for a way to make my headset Bluetooth capable to listen to music as I work and stay safe at the same time. I’d prefer to keep the electronics inside the cup’s and add a charging port somewhere on the cup. It cannot jeopardize the safety or current utility of the headset. Any help in creating this would be greatly appreciated by a guy who’s obviously not as smart as y’all are.
