kv4p HT is a homebrew VHF radio that makes your phone capable of voice and text communication completely off-grid with at least a Technician class amateur radio license.

The radio simply plugs into the USB C port on your Android smartphone and transforms it into a fully-fledged handheld radio transceiver. It's completely open source (GPL3): the Android app, ESP32 firmware, PCB designs, and 3D printer files.

It's small enough to fit in your pocket and take anywhere, and since it has no internal battery it's the perfect radio to put in a go-bag or your car's glove compartment.

any hams see this, and does it look viable?

You can't disprove flat earth theory... or can you?

The Break key is a keyboard key whose original purpose was to immediately halt execution of a running a program. On modern computers, it has no default function. It is not commonly used, although any software may use it for its own purpose. The Break key may also be remapped with a program like AutoHotkey.

We will all have seen disabled people who do not have the use of their hands, attempting to communicate using 'unicorn sticks' or even eye-tracking technology. I considered this and wondered if the simple Makey Makey board could be pressed into service to provide a quicker and lower-cost way to replace a mouse and thus facilitate a whole host of ways to communicate.

We all know how sensitive and controllable our tongues are. We can easily send our tongue to any tooth and the tip can easily determine items as small as a piece of trapped food or even a human hair.

Since many disabled people still have the full use of their tongue, it occurred to me that it may be possible to put together a mouth controller using the Makey Makey interface to connect to an onscreen keyboard.

Was brainstorming some ideas like this and found something that already exists that I thought was interesting to share

as well as the rinds of many other fruits or foods

The centralization of the internet poses a fundamental threat to individual freedom. In 2024, a few corporations control most internet services and infrastructure. These corporations wield immense power over most of us with little accountability, enabling them to censor content, exploit our data, and exclude users from services they depend on —all with profound implications for democracy. We need a solution urgently.

Introducing Freenet — a decentralized replacement for the world wide web. Acting as a global, shared, decentralized computing platform, Freenet can either be accessed via a standard web browser or integrated into third-party applications.

Something I was experimenting with, making a list or "inventory" of all the "stuff" (physical or non-physical / digital) in your life, in order to make better use of it

Some "stuff" has been haphazardly acquired in my life, as gifts or things I've gotten without a plan on how to use them, or digital files I'll get to "one day"... having a list of these things makes it easier to actively manage them (get rid of unused / unwanted stuff, make more regular use of things I have that I may not use much that I want to use, etc.)

Anyone gained any insights from making an inventory of "stuff" in their lives?
