Hackaday Links: July 30, 2017

What are you doing next weekend? How about going to the Vintage Computer Festival West at the Computer History Museum in Mountain View. Hackaday is sponsoring, and there are always a ton of awesome builds. Last year, someone played Tron on a Commodore PET. Not a video game — the movie.

In case anyone forgot, I created the most desirable independent hardware badge this year at Def Con. It’s a hilarious joke, I got three from OSH Park, thirty more in different colors from Seeed, and something, somewhere, jumped a shark. [Drew Fustini] also shared these PCBs on OSH Park. There were four orders. This is hilarious.

‘Member Minecraft? Redstone was awesome, and people built computers out of red dust and torches. Now it’s not as cool with all the fancy redstone components, and simpler is always better. Here’s bitmap logic, or a complete computer made with pixels. There’s already an 8-bit computer for this thing.

Frag somebody and own their computer. [Justin] recently found an exploit in Valve’s Source engine (TF2, CSGO, Portal 2…) that allows for remote code execution on clients and servers by loading a custom ragdoll model.

High bandwith, low-power, and long range. If you’re doing RF, you may pick two. LoRa is the RF solution that picked low power and long range. There are quite a few companies behind it, but we really haven’t seen many products using LoRa here in the states yet (then again, products that would use LoRa shouldn’t be very visible…). Now there’s an Open Source LoRa backend server. This is somewhat significant; LoRa isn’t a completely Open protocol, and all licensing goes through Semtech and the LoRa Alliance.
