Force Phone View: Firefox Extension

If you’ve ever tried to browse the web in split-screen mode on a small laptop, you know the struggle. Most websites stubbornly cling to their "grid" or desktop layout, leaving you with tiny text and horizontally overflowing content.

Force Phone View is a Firefox extension designed to fix exactly that. By tricking websites into thinking you're on a mobile device, it forces them to deliver a clean, column-based mobile layout that fits perfectly into narrow windows.

Key Features

  • Mobile Spoofing: Automatically sends an Android User-Agent to ensure the site delivers its mobile-optimized version.
  • Width Constraint: Constrains the page viewport to 720 pixels, a width that reliably triggers column views instead of desktop grids.
  • One-Tap Control: Toggle the effect on and off instantly using a simple button in the Firefox extension popup.
  • Enhanced Readability: Perfect for researchers, students, or anyone multitasking in side-by-side windows.

How It Works

The extension operates silently in the background, only activating on http and https sites to ensure security and stability. Once toggled on, it:

  1. Spoofs your browser identity as a Firefox Android device.
  2. Adjusts the zoom and viewport settings to match a 720px wide mobile screen.
  3. Injects custom styles to prevent horizontal scrolling, keeping all content in a single, easy-to-read column.

Technical Snapshot

For those interested in the privacy and performance side of things:

  • Privacy First: The extension includes data_collection_permissions: none, ensuring your browsing remains your own.
  • Lightweight: Designed as a Manifest V3 extension for modern performance and security standards.
  • Compatibility: Specifically optimized for the latest versions of Firefox.

Stop squinting at desktop sites in narrow windows. Switch to Force Phone View.

Arduino FM Radio Transmitter

This following is re-post of an article from my old blog from 2008: This is an FM radio transmitter I made using an arduino and a NS73M FM Transmitter. I got the idea from an article on hack a day, if you’re interested in building your own you should check out Mike Yancey's page he built the one that made it on hackaday.com and he does a very thorough job of documenting how all the components hook together. I was impressed by the level of finishing he was able to achieve on the housing; it looked like a commercial product. I wanted to see if I could achieve a similar result, it’s amazing what you can do with some simple hand tools. If your patient with the file, you can make perfectly square holes in aluminum.   On my implementation I omitted the de-bouncing circuit that he has connected to his rotary encoder, and I used a two-line display. Since I omitted the de-bouncing circuit, I couldn’t use the original rotary encoder library since that code uses a hardware interrupt a...

NES game pad

 This is re-post of a blog post I did about 15 years back, I don't know if I would use an Attiny microcontroller if I was to do this today. The price of chips with built in USB is now cost comparable, and hardware USB is more reliable. But it's a fun project and if you happen to have a microcontroller compatible with V-USB it's worth a try.   I was digging though some of my old junk and found a box of old Nintendo stuff and I thought that it might be cool to turn one of the controllers into a USB game pad. Now you can buy a USB NES style gamepad, but what's the fun in that. So, I started looking though my box of electronic parts and found a couple of Atmel Attiny 85 micro controllers. Sweet a chance to try out the AVR-USB library . Now you would think you need a clock crystal to sync the micro controller with the USB, but the AVR-USB library has an algorithm to calibrate the internal oscillator to within +/- 1% accuracy. Which is fortunate because if we had to use a cl...
