The difference of this project is that it is not in my house, it is in my touring caravan. Before anyone has a go about caravans clogging the roads up ect I do agility dog shows most weekends, so it is either use a caravan or use a tent, and a tent doesn't offer any think the same level of comforts.

 

Anyway. This is my thinking. I use the caravan 99.9% away from a 240v main electrical hook up, so everything is ran from my 2 12v 110amp leisure batteries, therefore power saving is of the highest importance. At the moment I have a 12v-240v inverter which powers a laptop with an external USB TV tuner and an external usb3.0 hard drive with a bunch of media for us to watch. This has worked for the past 12 months but whoever is lieing in bed closest to the laptop kind of blocks the other due to the layout.

 

What I am thinking of doing is installing a pico-projector above the head of the bed, to go straight down the to the white window screen. Then install a car stereo with an Aux in and stereo speakers for the audio. The screen is 100cm wide by 50cm high, and the projector is roughly 182cm from the screen, but there is a +/- 10cm each way where I can mount it easily. I am aware these projectors are not the brightest but with the blinds down the caravan gets pretty dark anyway and there certainly are not any street lights.

 

I have been looking at pico-projectors and they mostly have a 240v AC plug which goes to a 12v DC input, so I was thinking there must be a way to wire this in direct without having to go with a 12v-240v inverter to go back down to 12v and get losses in the process of doing that? Obviously the car radio and speakers will be 12v anyway.

 

My next thinking was how am I going to get media onto it. a USB input that plays the media on my hard drive would be great but I am not sure what I am going to do to get the coax freeview TV signal into it.

 

Any thoughts, or ideas would be appreciated.

Well after a lot of thinking an planning and putting on the back burner I have actually done something with this ready for the start of a new season. I bought a cheap projector off eBay, cheap because it doesn't need to be anything fancy, and it needed an external power supply. So I got a MediaLy G150X off eBay along with a laptop car charger and a cigarette lighter to crocodile clips to connect the leisure battery to the car charger.

 

Got it all put up together and tested it. First issue was the TV tuner built into the projector was analogue online, so I have had to buy a small freeview box that can be powered off the laptop car chargers built in USB charger. This I haven't tested yet but will be next weekend. I have tested it running off my 1TB portable USB hard drive and that works perfectly. The projector works and gives roughly a 40" image on the caravan blackout blind  :woot:. It has a built in speaker, but that is a bit quiet. I can easily plugin my Bluetooth speaker if I want to make it louder.

 

Audio is next on the list, I'll be fitting a car stereo with some 5inch speakers when I can afford it. I think so far the spend is about ?100, but I maybe looking to purchase a 3rd leisure battery in the future, but I'll see how it goes. I did some quick maths and I think 1 battery will run the projector for about 7-8 hours. (110amp/h battery running a 60w projector, other bits are negligible.)

no, the sites we go to are usually just farms or fields next to big manors, Rockingham castle is a good example. We have to use 12v leisure batteries and a generatorto charge them at longer shows.

 

I used to tour with a few bands i was in back in the day and we used to just upscale from a leisure battery and use anything we like. Can you not just do that? Or am i missing the point completely? :p

yea I have a 150w 12v - 240v inverter. But it seems silly to go from 12v upto 240v then back down to 19v. That's quite an inefficient way to do it, wasting power as it converts. Since I need the batteries to last as long as possible being efficient is a priority.

If you have a 12v DC source, you need to gut your projector and wire it directly into it. Pick up a multimeter and get to it.

 

That is part of the reason I got the one I did. I uses an external power block the same kind of thing as a laptop uses. Which is why I can run a car laptop power block to run it.

A photo I took of my fiance and niece watching lady and the tramp (both blocked out for their privacy but you get the idea). Cupboard above them is open for my bluetooth speaker to sit in. Next thing to look into is installing a car stereo head unit and a couple of car speakers somewhere to provide sound from the front rather than from above.

    • Was sold until I saw that small 7" screen size. My 2022 AOK ZOE already had 8" and it was base model.
    • GOG store introduces One-Click Mods feature with support for Fallout: London and others by Pulasthi Ariyasinghe The GOG store just announced a new feature to its platform that it is calling a new era for modding. Revealed at the PC Gaming Show, GOG One-Click Mods functions exactly like it sounds like, letting PC gamers browse, install, and play community creations easily and without jumping through hoops. "Mods are an essential part of video games preservation, allowing you to relive your favorite stories in countless possible ways," said the GOG team today. "Mods management, however – is not for everyone. Digging into game files, installing requirements, restarting the game thousands of times, making it crash every time… But no more." Unlike other modding platforms that let anyone upload their creations and let the user work out the details, GOG's version is a curated experience. By working directly with the modding teams, the popular DRM-free store's staff will be making sure that each of the mods available works instantly with the game, with no need for additional research or add-on installations. "From bug fixes, restored cut scenes, quests and characters, to completely freshly-made new content – we teamed-up with these community-driven projects creators to offer you this list of handpicked Mods," added the company. "Combining our strengths, these are now accessible right away, already installed within the base game for the smoothest experience!" Here are some of the mods available right now on the new platform: Horn of the Abyss for Heroes of Might and Magic 3: Complete. Horn of the Abyss is an expansion for Heroes of Might and Magic III that adds new factions, campaigns, creatures, artifacts, and numerous quality-of-life improvements, such as a working multiplayer lobby system. Phobos mod for DOOM 3. The Phobos Mod for DOOM is a prequel to the original game, delivering a narrative-driven, classic-style FPS experience with modern enhancements, set during the UAC's initial experiments on Mars' moon Phobos, adding many new gameplay hours. Vampire: The Masquerade – Bloodlines Unofficial Patch for Vampire: The Masquerade - Bloodlines. The Vampire: The Masquerade – Bloodlines Unofficial Patch does not only fixes numerous bugs left unresolved by the original developers but also restores and enhances cut content such as quests, levels, characters, and dialogue. Fallout: London One-Click experience for Fallout 4. You already had a chance to experience how great Fallout: London is – an alternate standalone storyline set in the United Kingdom, during the apocalypse events from Fallout 4. Now though, you can boot it with just one click – no launchers, no extra steps, just pure fun. Following that, the GOG team is working on introducing support for the Skyblivion total conversion mod when it releases later this year. This will let those who own The Elder Scrolls V: Skyrim Anniversary Edition on the platform install and jump into the modded Oblivion experience on the Skyrim engine easily. Check out the newly set-up mods platform on the GOG store by heading over here.

    • Once the first went to a full version number, some just egregiously long numbers with every iteration of compilations/dates/times... what have you, it was a landslide. Long gone are the days of IE version 6, 7... now it's Edge 137.0.3296.16. So, why not iOS 2026.18.8778.322.10.800? Shocked that Edge isn't 2025.137.0.3296.16... seriously. When Samsung went from S10 to S11, to S20... to S21... I thought they were just doing new iterations of the same/similar models, then the next would have logically been S30/S31... but nope. Oh well... better things to think about then version numbers, leave that to the devs.
    • The problem -- as pointed to by the PowerShell output I quoted above -- was that for some reason it couldn't download the NuGet provider. Here's what did work: (1) Download the raw nupkg file (set-inetpubfolderacl.1.0.0.nupkg) from https://www.powershellgallery....s/Set-InetpubFolderAcl/1.0; (2) Extract (e.g., via 7-Zip) the Set-InetpubFolderAcl.ps1 file into C:\Program Files\WindowsPowerShell\Scripts; (3) Run the script via PowerShell as described in the quite thorough instructions given at https://www.windowslatest.com/...t-on-windows-11-windows-10/ . That worked for me, or seemed to. Oh, relief!
