I designed this device that teaches binary, decimal, hexadecimal and octal number systems. It uses a hands-on approach with Altair-like toggle switches. Can be used as a STEM-kit in classrooms, handy for programmers or for the retro hobbyist. It also has a built-in game. Check out the video for details, hope you like it.

I bought a *nice* charger because I have to charge stuff quickly for work. After buying 60w USB-C cables and a 160w charger I'm getting a blazing fast... combined 20w? What the heck?

Turning adaptive charging off/on did nothing. Trying different plugs did nothing.

How do I achieve the Pixel 9's advertised 27w charging...

I'm looking for a grounded multiport USB-C PD charging "hub", as in one that plugs in to mains via a cable, as where I need it is nowhere near a wall socket. I currently have an Anker one, however it is not grounded (just uses a figure-8 connector for 240v) and it causes a few issues.

The main issue being that it shocks me if i touch my MacBook and my older ThinkPad at the same time while they're both charging (MacBook plugged into the Anker charger, ThinkPad's barrel jack plugged into its power brick), as the ThinkPad ends up grounded while the MacBook ends up connected to neutral (I believe? Correct me if I'm wrong.)

Another issue this causes is if I plug my charging MacBook into my studio monitors (plugged into the wall, grounded) there is a very loud hum/buzz through the speakers until I unplug the MacBook from the charger.

Everything I can find is either the exact same as what I currently have (cabled but not grounded), or plugs straight into the wall. Does anyone know of a charger that meets my requirements? I'm not enjoying my current one shocking me all the time. Thanks in advance!

Wheree can i buy a charger 45 watts supervooc for Oppo?

The intricacies of charging these days are mind boggling. I would like to buy one wall charger box for all 3 devices. The printer is a dex cord 100w. So all 3 are usb c into the wall charger.

I thought I'd buy this anker charger but none of their products that I can find actually *have* PIQ 4.0. I need 3.1 PD and PPS charging.

Long story short if any of these 3 devices go down during my 16 hour days I am a sitting duck and I'm tired of struggling with so many different chargers.

Hoping some brainiac out there knows more than I do about all this jargon.

So three usb C ports 100w, 27w, 23w with PD 3.1 PPS charging.

I had both DACs, used for portable phone in pocket wire faudio playback and they both bent up after 20 months and left audio stops working. Any good ones for under $20

Hey guys, I have been using a OnePlus 12 since 2024 and to charge it, I initially was using the 100W USB-A to USB-C charger they bundled with the box but it was heating up my phone by a bit which I did not like.

So I switched to the older 65W USB-C to USB-C charger I had which was provided with my old phone (OnePlus 9 Pro). I especially liked this charger because it could even charge my laptop at 45W and generally fast-charge a bunch of other devices of my friends and family.

The issue at present is either the cable or the brick itself has gone bad I guess because often times it does not charge my phone reliably, it sometimes charges > disconnects immediately > then charges again > disconnects in a loop. I have my suspicions on the cable as it already has electrical tape around its ends to shield slight tear of the insulation.

So now, I am looking for a decent charger that can fill its role. I want this new charger to charge my OnePlus 12 quickly, preferably at the same speed as their proprietary 65W protocol but also support fast charge protocols of other brands like Apple, Samsung and others so that if I switch my phone in the future, I could still use this charger. I also want it to charge my laptop (Currently I have a 2020 Asus G14, may switch in the future) at a decent rate (do not need crazy high wattages or enough to game off of, just a decent enough speed to quickly come in handy at a library or a cafe).

What charger + cable combo do you recommend?

Thanks in advance.

i have a bunch of TVs/monitors around, so i figured i'd use USB hubs to plug in the device i want to use in the moment. so i got a heap of aliexpress usb-c hubs for cheap.

at least 3 of them don't work properly now, after some use. i figure everything i bought will probably have a short lifespan.

anyone have any experience here? can i stuff them with thermal paste and get good results?

i hate how trash usb hubs are like 4$, and the one i bought at bestbuy was $50 and old now but it's trucking along fine.

i wanna fix/durabilify the cheap shit, or at least not spend >10x for non-garbage.

advice?

I found out that it does support pd 3.0 but i couldn't find a reliable source that confirms it supports pps as well

My laptop only has 3 ports: thunderbolt USB-C, USB-A, and aux. If I buy a high-quality HDMI->usb-c cable, will it charge my laptop ***and*** work as an external monitor?

Links/names of quality cords are appreciated :) Also, if there's anything to lookout for in the item description to make sure it does both, lmk.

Would rather not get a splitter as that lowers refresh rate to a max of 60Hz. Thank you!

Yo! I have a usb C hub I connect to my phone (Redmagic 11 Air) everytime I play using my keyboard and mouse, my mouse works perfectly fine but the keyboard doesn't work until I hold CTRL, if you guys know a good hub specificly for phones plz tell me (I only need usb ports)

And if you know a solution plz tell me too, my hub company is VAVA
