I want to build a wooden frame for a 120" projector screen. I want it to be portable and foldable, as I will not have it in 1 fixed location.

I thought of something like this: 2 half-frames with a hinge. It gets opened, and on the front, with velcro, I attach the screen cloth.

Will it work? Has anybody done a foldable screen? Any cons?

According to mashable and other sites, the deal for 50% is up until December 30th, today, but it is already saying: "HOLIDAYF25: This promo code is invalid and will not be applied."

Any idea if it is really over? thanks

I am new to this, and I want to get a reseller panel to offer IPTV to my family and friends. But I have a few questions:

1. From what I understand, Strong 8k is a large server that offers reseller accounts, which in turn can resell accounts (according to credits), so it is essentially a pyramid reseller scheme. if i understand it correctly if a scammer stopped or quit with our money it will cause all sub-reseller accounts to be cancelled? You need to find a reputable reseller to avoid being scammed by someone who sells you an account and then quits, which can cause your account to be closed.
2. A "panel" needs an initial account with 120 credits. But how do these credits work? If I sell 10

I just started watching the Quantum Leap revival and I'm loving the concept, but some major changes from the original series are definitely leaving me with mixed feelings. I've made it through episode 7 now—what do you all think?

This is pure nostalgia, but I miss the classic, clunky QL tech! I miss the iconic white door to the Imaging Chamber and Al’s constantly-glitching handheld Ziggy device. The new HQ is very sleek and modern, but I miss that classic 80s sci-fi charm the original had.

1. The first thing that confuses me is the disappearance of the Waiting Room. Now that it’s gone, where does the leapee’s consciousness go? Does the person still observe everything Ben does but can't con

Yesterday I had a freeze in my Windows 10 system (X570 Aorus Pro), and when I rebooted RGBFusion 2.0 can no longer control/see the motherboard/RAM and the SIV system information can no longer control fans, they both freeze and crash, any tips?

Hey Reddit

So, I'm looking to buy the new Galaxy Watch Ultra (2025 model, but I guess the question is also valid for last year's Galaxy Watch Ultra).

I'm one of those people who goes through security checks every single day for work. Right now, I've got my old Galaxy Watch 4 Classic (the stainless steel one with a rubber band) and it never triggered the alarm, which saves me so much hassle.

The Ultra's got that titanium body, and I'm wondering if that's enough to cause issues. If you've got an Ultra and you're regularly going through security checks (think airport-style scanners, not just a handheld metal detector), could you please share your experience? Does it set off the detector for

Hey all,

I have an HP Z1 G9 Tower workstation with an i7-12700. It came with 16GB DDR5 and I need to upgrade to 32GB (2x16GB).

I found a local deal on Corsair Vengeance 2x16GB DDR5-5200MHz CL40.

Will this 5200MHz kit be compatible with my HP Z1 G9 workstation?

I know workstations can be particular about RAM (often expecting 4800MHz or specific modules). While it might run at a lower speed, I want to ensure it's stable and fully compatible.

Any experience with this specific machine and third-party DDR5 RAM would be super helpful!

Thanks

When I open the PB web page it shows the devices list I added, but not in the firefox extension.

I tried removing and reinstalling the extension, still nothing. how to fix.

Sono residente fuori dall'Italia da qualche anno, e durante questo ultimo anno mi sono scaduti la carta d’identità e passaporto. Il passaporto l'ho rinnovato al consolato locale ma la carta d’identità non si può'.

Non ho inviato niente alla banca in attesa in andare in Italia (tanto il passaporto porta come città' di rinnovo la città' estera). Ma la mia banca mi ha mandato una comunicazione se non invio documenti aggiornati entro 1 mesetto mi bloccheranno il conto.

Cosa si può fare in questo caso? che tipo di blocco intendono? blocco delle operazioni finché non rinnovo i documenti o chiudo il conto? se blocco temporaneo, posso aspettare fino alle mie ferie qua per aprire conto per non resi

Hi everyone,

I'm pretty new to the Zigbee world and excited to start exploring smart home automation. To get started, I picked up a Sonoff ZBMINIL2 to try out.

I initially got a Sonoff Zigbee 3.0 USB Dongle Plus to use as my coordinator, and I set it up with Zigbee2MQTT with my Home Assistant. However, despite following all the pairing instructions, the ZBMINIL2 would never successfully interview, and I couldn't get it to join.

Thinking the issue might be with my setup, I then decided to try the official Sonoff ZBBridge Pro gateway, hoping for better compatibility, but unfortunately, it also had the same problem – it simply refuses to pair as it doesn't even show in the Android App for so

I have a 500mbps symmetric fiber internet connection with a fiber router from my isp, which is connected to my FritzBox 7490 via LAN1 to provide the internet to my network, and it was all fine until 2 days ago when I installed the latest 07.60 firmware for the fritzbox, now my speedtest is capped at 50mbps download/100mbps upload.

The fiber modem still tests as 500/500 but behind the fritzbox it became much slower.

Tried to change the settings, remove the power consumption saving thing, still nothing more than 50mbps download.

Any idea how to fix it? can I go back to the 07.59 firmware with the recovery exe firmware? I have a copy

I got a Hikvision DS-UPS2000 UPS for the network rack in my office, which is near my workstation, but the fan noise of the UPS is really annoying, starts and stops every few minutes and it is really noisy, I can here it from the other room.

Is there a way to fix it? is it necessary? other UPS systems with same VA doesn't have fans, why does this need one?

Tried to connect the UPS to a PC to see if via the monitoring software I can change fan speed, but I cannot find any software for managing the UPS.

This has been asked before, but it seems currently there is no solution:

Firefox's default behavior when using the mouse middle-click on an empty area of the tab bar area will create a new tab; I don't want this behavior. How can I disable it?

On the posts linked above they mention using UserChrome.css, I enabled it and tried, doesn't work. custom scripts work but not disabling this feature.

I use DisplayFusion on my multi-monitor setup since years, and middle-clicking a window titlebar or Chrome tab bar or Firefox tab bar will move the current window to a second monitor.

Currently

Hey everyone,

I'm running a home lab and using Let's Encrypt to generate SSL certificates for my local services (I followed many guides to implement this with Nginx proxy manager and Cloudflare). I have a domain for my home lab, and I am using it for this. This is great for having valid HTTPS connections, but I’ve been having issues with antivirus software and Google Safe Browsing tagging these local services as dangerous or phishing sites.

Previously, I was using Bitdefender, which consistently blocked access to these services (And a bug in Bitdefender would not allow me to whitelist the domain name). I switched to ESET, and now Google Safe Browsing is doing the same thing, preventing acc
