If you are able to slack off at work like this, is there something that you would rather be doing with your time? I am not judging. I've worked at places where I spent 75% of my day slacking off because the management and bureaucracy was terrible. After months of doing that, I started hating the job. I can only check facebook/reddit/pick your poison, for so long before I want to throw my computer out a window out of…

This is like adding an event listener to door open and providing a callback. It's pretty great

Looks like it doesn't work anymore, but at one point someone styled reddit to look like you were reading a Word document: https://pcottle.github.io/MSWorddit/

similar but styled as code: http://codereddit.com/

I once did a stealth chat client. In emission mode, it logs keystrokes and sends them as messages. In reception mode, it autotypes the replies.

The idea was that you can open your usual work editor (word processor, IDE, spreadsheet, ...) and use it as a chat client.

It was more like a proof of concept, it didn't work that great and wasn't really useful. Also such a tool is likely to trigger all kinds of alerts in antivirus software, for good reasons.

I could see real uses for these, but I'd want questions answered first such as whether they're specifically paired, where the programming is stored, what data passes wirelessly, whether there could be any way the receiver could act as an open HID receiver device, what the number of triggers is, etc.

From a quick glance, it's a custom radio packet using a common 2.4 GHz proprietary radio (clone of nrf 24L01), and it doesn't really need more than that. Adding complex pairing and so on would likely kill this fun passion project way long before finishing.

Oh hey. I just used some SPI-based Nixie tube drivers that this same tindie user made. I've been super impressed!

Came to say something similar - in the spirit of his/hers exixe tube thing, I made a similar one but with msp430 (since I'm very familiar with it) and cleaner layout of the transistors. Looks good and have baked a couple, but I'm not getting good results on flashing the msp430. For some reason it's flaky as hell, and I don't have the time to investigate more.

Nice. Should really use BLE though so you don't need the receiver - nRF52 or ESP32 are the best options.

With that, you'd need a client software on the computer, pairing etc. His receiver acts like a keyboard that just sends win+m when triggered. Neater, imho.

Well, gait is usable as a biometric identifier. While most approaches use video analysis, I found this a paper [1] that is about identifying people through footstep induced structural vibration using a geophone[2]. It would be quite interesting if it is possible to measure the structural vibration using a laptops or smartphones built in accelerometers. But I think acoustic sensors would be a better way. Or a combinat…

Interesting - can you provide [1] and [2] please?

Yikes, it was a bit too late in my timezone, sorry.

USBKill ( https://github.com/hephaest0s/usbkill ) lists one approach to solving that problem in its README: - Set USBKill to watch the status of a particular USB port - Attach a lanyard to a USB key - Wear the lanyard on your wrist - Plug the USB key you're wearing into the port USBKill is watching Then anytime you step away from the machine, USBKill would notice the removal of the key and shut it down.

This would just result in my yanking my laptop off the desk every time I got up.

I think with a short USB extension cord it could work. Moving away would angle the cord at just the right angle to pull the device out (from the end closer to you -- the other end would be at an angle and stay inside from friction).

I wonder how far you could get at doing this with no additional hardware. Could a smart enough AI detect the boss's voice with the microphone? Some other mannerism like the way they clear their throat? Face detection with the camera? Maybe something with Bluetooth or WiFi and the boss's smart phone?

Last one sounds the most promising, if clients (rather than base stations) can be uniquely identified, and often enough to be practical. I know that base stations send a beacon out x times per second, but phones probably don't.
