Yo Dawg, I Heard You Like FPGAs
When the only tool you have is a hammer, all problems look like nails. And if your goal is to emulate the behavior of an FPGA but your only tools are FPGAs, then your nail-and-hammer issue starts getting a little bit interesting. That’s at least what a group of students …read more

Breakout Board Becomes Pogo Pin Programmer
Making a programming jig becomes exponentially more difficult after two pins and who would even consider building one if they were not setting up more than twenty boards? If it were easy for novices to construct jigs, we might all have a quiver of them on the shelf next to …read more

Play Tetris on a Transistor Tester, Because Why Not?
[Robson] had been using the same multimeter since he was 15. It wasn’t a typical multimeter, either. He had programmed it to also play the Google Chrome jumping dinosaur game, and also used it as a badge at various conferences. But with all that abuse, the ribbon cable broke and …read more
How To Program A Really Cheap Microcontroller
There are rumors of a cheap chip that does USB natively, has an Open Source toolchain, and costs a quarter. These aren’t rumors: you can buy the CH552 microcontroller right now. Surprisingly, there aren’t many people picking up this cheap chip for their next project. If there’s no original projects using this chip, no one is going to use this chip. Catch 22, and all that.
Like a generous god, [Aaron Christophel] has got your back with a working example of programming this cheap chip, and doing something useful with it. It blinks LEDs, it writes to an I2C display, …read more

Crash your code – Lessons Learned From Debugging Things That Should Never Happen™
Let’s be honest, no one likes to see their program crash. It’s a clear sign that something is wrong with our code, and that’s a truth we don’t like to see. We try our best to avoid such a situation, and we’ve seen how compiler warnings and other static code analysis tools can help us to detect and prevent possible flaws in our code, which could otherwise lead to its demise. But what if I told you that crashing your program is actually a great way to improve its overall quality? Now, this obviously sounds a bit counterintuitive, after all …read more
A Portal Port Programmed For Platforms Of The Past
If you still have a Commodore 64 and it’s gathering dust, don’t sell it to a collector on eBay just yet. There’s still some homebrew game development happening from a small group of programmers dedicated to this classic system. The latest is a Portal-like game from [Jamie Fuller] which looks like a blast.
The Commodore doesn’t have quite the same specs of a Playstation, but that’s no reason to skip playing this version. It has the same style of puzzles where the player will need to shoot portals and manipulate objects in order to get to the goals. GLaDOS even …read more

A Whole Other Kind Of Graphical Programming
Java isn’t everyone’s cup of tea. With all its boilerplate and overhead, you’re almost always better off with a proper IDE that handles everything under the hood for you. However, if you learn a new language, you don’t really want to be bothered setting up a clunky and complex IDE. If only you could use a simple, standard Windows program that you are most likely already familiar with. This wish led [RubbaBoy] to create the MSPaintIDE, a Java development environment that let’s you write your code in — yes — MS Paint.
If you’re thinking now that you will end …read more

Become The Rockstar Developer You’ve Always Dreamed Of Being
If you have ever worked in software-related industries, the chances are that the word “Rockstar” will elicit a visceral reaction. It’s a word used by a Certain Type Of Manager for an elite software developer who’s so 1337 they don’t play by the rules of ordinary mortals. In reality it’s use is invariably an indication of trouble ahead, either from clueless startups or troublesome rockstar developers making a toxic atmosphere for the mere members of the backing band. Hackaday has a team that brings together a huge breadth of experience, and we’ve been there.
Would you like to be a …read more
