Hey everyone, I have a question. I have a bunch of crap around that I use: two HDD docking stations, a powerbank, a CCTV cam, a few microcontrollers. They all consume either 5V or 12V. I'm a bit weary of having a web of wires and a bunch of wall warts everywhere. I have an older but...

* Work in progress, see post 2 * Hello everyone, I've been slowly making a thing for a while now. As I have some spare time, some money, etc. Basically what I'm building is a cheap but quite robust wireless environment sensing and alarming device. Operating principle: 1. Detect a fire by...

I noticed this section of the forum is a bit dead, and I got into embedded stuff the last few months. So why not give something back. I'd like to show you guys and gals a pretty clever and dirt cheap wireless CCTV solution. It was also my first foray into ESP32, which is a tiny WiFI/BT-enabled...

Hello good people of [H]. In light of recent events, including my mom's bladder cancer and someone else's problem (you know who) I decided to pull my head out of my ass (did you hear that pop?) and go crazy with folding. Until now, I only had 1 device folding - a computer at my old job. (i3 @...

Right, so. I'm in a new place nowadays. A block of flats with 6 famlies. We have a common 24V line to each famiy's basement/storage area. I could easily power some computing devices like PIs and fold for 'free'. But - seems morally wrong. It'd be for a good cause, but TBH feels wrong to leech...

Hello! Does anyone know about a good (preferably free) program to simulate electromagnets? The closest I've found is quickfield, but it has a very limited mesh size in the free/student tier. This would be for designing and simulating solenoids and halbach arrays.

Yeah hi, I like to insert various funny images/illustrations into my posts. To offload Hardforum, I usually host it on freebie hosting sites. Is the drag&drop [H] hosting okay to use for such shenanigans? Up to what resolution?

Guys, What if I told you I have a LG DVR with a 400GB Seagate IDE drive in it and would like to copy files from it? I have it physically connected to an older mobo with an IDE port. Windows sees it as a 750GB drive with some unallocated space and two 'unknown' partitions. (Older) Debian...

GENTLEMEN. I got a new jerb. I inherited a medium sized (50 devices?) wired network at a military clinic. I will be putting together my work computer tommorrow, and thought I'd start with a basic audit as a starting point for a stroll around the offices. Would you kindly recommend a tool...

Any Minecraft fans be sure to check out their game today :D At first I thought my GPU was acting up because I overclocked from 350 to 450 (an ancient 7100GS), and then it clicked :D Happy Christmas everybody! we got gifts!

Gentlemen. I don't know if it's important, but in light of recent problems I feel it is my duty as a human being to let you know that hardforum.com was out cold at around Noon CEST for like 10 minutes. I checked via isup.me and it wasn't just me.

Hello, I've used Linux (KateOS, Debian, Mint) on the desktop from like 2008 to KDE 4. I really liked KDE 3.5 and read about the fork - Trinity. I dislike Gnome, Xfce, Unity and the like for various reasons. Has anyone had any experience with Trinity it on Debian, Ubuntu, Mint or something else...

Guys, I honestly was thinking about doing some work today, it's the last day of the month and I have deadlines. Today at work I was greeted by my phone screaming it's little speaker out. Multiple machines got hit with a 'upgrade to Windows 10' nag screen with just two options - upgrade now or...

Hello audiophiles, I'm preparing a gift for a friend. He recently got himself a pair of some nice sennheiser headphones. I would like to give him my USB DAC. It draws power from USB. As it does not do any amplification beyond the PCM2704 DAC, I am planning on connecting Left,Right and...

Hi there A funny thing happened on my way to salvage enameled copper wire from the transformer of a dead UPS unit. As I cut some of the primary wiring I noticed it's actually... Aluminum. Same on the secondary. Its insulation is copper-coloured but the cross-section is all Al. The...

Hello everyone, I used to play around with VMWare server a bit, somewhere around version 2, anyway I remember the transition to that web based UI. Apparently now only the Player edition is free... right? Server had a lot of neat features like VMs autostart and CLI control, which I fail to find...
