These Small PCBs are Made for Model Rocketry — Hackaday

Model rocketry hobbyists are familiar with the need to roll their own solutions when putting high-tech features into rockets, and a desire to include a microcontroller in a rocket while still keeping things flexible and modular is what led [concretedog] to design a system using 22 mm diameter stackable PCBs designed to easily fit inside rocket bodies. The system uses a couple of 2 mm threaded rods for robust mounting and provides an ATTiny85 microcontroller, power control, and an optional small prototyping area. Making self-contained modular sleds that fit easily into rocket bodies (or any tube with a roughly one-inch …read more

Hack Excel for 3D Rendering — Hackaday

[C Bel] teaches Excel and he has a problem. Most of us — especially us Hackaday types — immediately write a VBA (Visual Basic for Applications) macro to do tough things in Excel. Not only is this difficult for non-technical users, but it also isn’t as efficient, according to [C Bel]. To demonstrate that VBA macros are not always needed, he wrote a 3D game engine using nothing but Excel formulae. He did have to resort to VBA to get user input and in a very few cases to improve the performance of large algorithms. You can see his result …read more

Flexible QaudCopter Is Nearly Indestructible

We’ve all crashed quadcopters. It’s almost inevitable. Everything is going along fine and dandy ’till mother nature opens her big mouth a blows a nasty gust of wind right at you, pushing your quad into the side of a wall. A wall that happens to be composed of a material that is quite a bit…

$10 Raspberry Pi Zero W Adds WiFi and Bluetooth

The Raspberry Pi was born on February 29th which means we’re only three years away from its second birthday, and a new hardware release from the Pi Foundation is becoming somewhat of a tradition. This year is no different: a new Raspberry Pi has been announced. The Raspberry Pi Zero W is the latest iteration of…

Taking A Robot For A Drive

Instructables user [Roboro] had a Mad Catz Xbox steering wheel controller he hasn’t had much use for of late, so he decided to hack and use it as a controller for a robot instead. Conceivably, you could use any RC car, but [Roboro] is reusing one he used for a robot sumo competition a few…

Octosonar is 8X Better than Monosonar

The HC-SR04 sonar modules are available for a mere pittance and, with some coaxing, can do a pretty decent job of helping your robot measure the distance to the nearest wall. But when sellers on eBay are shipping these things in ten-packs, why would you stop at mounting just one or two on your ‘bot?…

The World’s Lightest Brushless FPV Quadcopter — Hackaday

When a claim is made for something being the world’s lightest it is easy to scoff, after all that’s a bold assertion to make. It hasn’t stopped [fishpepper] though, who claims to have made the world’s lightest brushless FPV quadcopter. Weighing in at 32.4 grams (1.143 oz) it’s certainly pretty light. The frame is a…

How to Create a Virus Using the Assembly Language — cranklin.com

The art of virus creation seems to be lost. Let’s not confuse a virus for malware, trojan horses, worms, etc. You can make that garbage in any kiddie scripting language and pat yourself on the back, but that doesn’t make you a virus author. You see, creating a computer virus wasn’t necessarily about destruction. It […]
