Slashdot Syndrome, where you're so concerned with performative anti-corporatism that you're incapable of empathy with non-tech people nor of making rational computer security decisions.

One thing building this battery reminds me is how silly it is that folks upsell "charge while using the battery" is.

For low current devices, this is a trivial feature. What matters is bringing current in across a diode and not reverse flooding whatever kind of boost-buck you have on the charging port.

Charging the battery for the radio load test I'll do later today. My BMS actually supports charging but I won't use that feature (because I got bored of soldering and didn't have a spare barrel jack, and instead use a very smart RC charger on the actual poles.

Enthusiasts analyzed memory backups and discovered that entries in the calculator's CUSTOM menu pointed at specific memory locations. With this knowledge, a hack was devised where a special string could be inserted into the backup at the proper location to allow the calculator to execute assembly language programs. These programs could run much faster than their BASIC counterparts and be much more efficient in terms of memory usage. This development made the TI-85 the first TI graphing calculator that could execute assembly programs.

A Big Set Of Logic Gates For Teaching The Basics

Teaching students about logic gates is often done in two parts, once on the whiteboard for the theory, and again on the breadboard for the practice. [shurik179] wasnโ€™t a fan of the abstraction between easโ€ฆ hackaday.com/2021/01/24/a-big-

Ah, yes, Brave. The homophobe's cryptocurrency browser.

I'd really like to find someone with larger homebrew drone platform so I can get this on a drone. The coverage you could get from 200ft up during an event would be only limited by an urban skyline.

We can easily patch this into existing drone electricals. If I take out the battery weight, the weight is low and the power draw is negligible.

I am working with a friend on a platform to collect all local GMRS and FRS radio from a discreet backpack rig, for later forensic analysis, as part of future Antifa movements.

This is a proof of concept made out of parts I had lying around, but I can grab GMRS 1-7,15-22 and many repeaters and the entire kit fits inside a large adult backpack, with no external power.

The Pi itself has no problem dumping this over USB3 to a fast SSD, but you need a big SSD and active cooling on the USB controller otherwise it janks out and throttles.

Once I have some GMRS or FRS captures, I will work on live 1 channel demod, which should be modestly easy to do. A web interface for discreet mobile control whole walking about is also a good call.

Longer term, I want to see if we can recognize if a channel is in use without full demodulation.

I'll start optimizing it to drop down the cost of the rig as well, as this is probably an essential toolkit against future militarized-but-poorly-educated fascist action.

Does the Virtual Hacker space have a dedicated network? So that folks can self host and share in an environment that isn't the internet?

It seems to me like avahi and wireguard might be a reasonably approachable. Folks have gotten it working.

My family is very excited for the return of ใ‚†ใ‚‹ใ‚ญใƒฃใƒณ (Yuru Camp, En: "Laid-Back Camp)". That anime is literally what made my partner decide maybe she'd like camping, and it turns out she loves it quite a bit. The first season made my daughter ask for a camping trip as her 5th birthday present.
