In my spare time, I've been slowly chipping away at the Light Meter Watch . The goal is to build an easy-to-use meter good enough for film photography (and maybe even do a small production run!) I'm building off the Joey Castillo's fantastic work on Sensor Watch , repurposing the venerable Casio F-91W. When conceptualizing this project, the first hurdle was obvious - where to place the light…
The Leica M10 family of cameras use the proprietary BP-SCL5 battery. Of course, Leica being Leica, these batteries cost an eyewatering $200 a pop. Even after many years, a third-party battery option has never materialized. These batteries are also often hard to find in-stock. Li-Ion batteries are consumables with a limited lifespan, and Leica is the only game in town, purely due to their own…
Beepy is a handheld Linux device, with a Blackberry-like keyboard and monochrome Sharp Memory LCD. It's normally powered by a Raspberry Pi Zero W. This document contains my notes for swapping out the Raspberry Pi Zero for a Radxa Zero instead. Why Radxa Zero over Raspberry Pi Zero? Raspberry Pi is great, but not ideal for handheld, battery-powered devices. Raspberry Pi doesn't implement suspend to…

Why VS Code? You Can Still Use Neovim The neovim extension runs an actual neovim instance! With your nvim config! Since it's an actual neovim instance, you'll never run into weird edge cases of specific vim features that haven't been implemented. It's Configurable The VS Code defaults did not work for me at all, but there's a good amount of configurability. Combined with the neovim plugin, it's…

Background I suffer from Delayed Phase Sleep Disorder (DPSD), which basically means a day in my body’s circadian rhythm is significantly longer than 24 hours. This results in me going to sleep later and later until eventually it just cycles around and repeats all over again. I started looking into therapy lights to try and help align my sleep schedule. Most therapy lights are typically designed…
After shucking the HDD out of a WD EasyStore, I was left with the USB to SATA PCB. SATA hard drives take both 5V and 12V to drive the motor inside, and the PCB takes a 12V barrel jack input that it then steps down 5V. I wanted to use these adapters with SSDs, which don’t need the 12V rail, but since the 5V rail is derived from the barrel jack input, I still needed to plug in the power supply to…

Category: Reversing Points: 200 Author: cutz Description: Silly Gunslinger Joe has learned from his mistakes with his private terminal and now tries to remember passwords. But he's gotten more paranoid and chose to develope an additional method: protect all his private stuff with a secure locking mechanism that no one would be able to figure out! He's so confident with this new method that he even…
