I aquired a cheap Hubsan Drone (H216A, X4 Desire) and wanted to know if its possible to control it without their app. The Drone opens a WiFi where you can connect your phone to controll it via an App. Using Bluestack & Wireshark I got some information...
(Duplicate of a HAD blog post, placed here for posterity.) Here's some things to try that might help depression. Firstly: there's a direct correlation between poor sleep and depression, but no one knows whether depression causes sleep disturbance or...
A little writeup I did on getting the aforementioned hardware running in my AM8, as I thought the existing documentation on the subject was a bit suboptimal.
Hoping a real chemist can sniff-test this: * This legit-seeming 2018 paper says some alchemical conjuration from coconut oil is The Most Amazing Bug Repellent: "Better than DEET Repellent Compounds Derived from Coconut Oil" https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6145915/...

Can someone suggest a reasonably-priced submersible water pressure sensor? It needs to be able to measure up to 3.5 bar (can be higher than this). Ideally it would have at least a 35m cable, though I can make a waterproof join if need be. ...
I'm working on a project for a USB HID device. Internally it has any number of 5V IC's. I really, *really* would like to use a Teensy 3.5 for this ... but they're sold out everywhere. Please, if you've moved on to Teensy 4.x but still have one lying...
Hi, I have built a simple DIY 3s2p battery pack from 2170 cells with balancing and anti-overcharge/discharge. I want to connect this pack directly to the battery connector of the Lenovo T540, replacing the Lenovo issued battery pack which is kaput. ...
Has anyone found a hack for this dumb problem. The SG90 comes with a splined nylon shaft (od 4.7mm). These make a precision fit with the actuating horns. If you want to fit a gear, you need a 5mm id shaft (say) A bodger might just use a connecting...
