C64 Hardware Simulator Isn’t (Just) For Playing Around
If you want to play old Commodore games, there are C-64 emulators available for just about any platform– but most of them are so high level, they’re really meant for just that: playing games. [antirez] has a different goal with his c64-hw-sim project— it’s a lower-level emulation that simulates every chip and every connection on an ASSY 250407 motherboard, and all the chips on it, too. Ever wondered what happens when a specific chip is missin
Hand-Machined Stake Sharpener Just In Time For Dracula Season
Vampires aren’t as common as they once were, but in most places they aren’t fully protected and it’s still possible to get a tag for legal hunting come October — at least if
So You Want To Make Your SDR Work On Other Frequencies
Perhaps the most exciting news of the past few weeks in the world of hardware hacking has been the unlocking of hidden SDR functionality in the Wi-Fi radios found on Espressif ESP32 microcontroller
A Thermal Camera That Uses WebUSB
When creating a peripheral for a mobile phone, an obvious path is to create a companion app with which to talk to it. But as we all know today’s app is tomorrow’s non-functional abandon
Building An M7 Pan Tilt Head Controller
The Soonpho M7 Pan Tilt Head is a useful photography tool for remotely aiming a decently-sized camera. Only, [Kyle Housley] wanted a little more control than was available out of the box. Hence, he
Pager Converted To Meshtastic Node
Text messaging has been around on cellular networks en masse for around three decades now. It’s so common that it’s difficult to remember a time without it. Its two-way quick messaging
AI Controls IPhone Via ESP32
Do you want to get an AI agent to do something to an iPhone? You could try and jailbreak the device and do some heavy software hacking, or… you could grab a microcontroller off the shelf and
Single Button, Handheld Gaming Console
Those of us who grew up in the 70s and 80s might be familiar with the Atari 2600 console and its now relatively unrecognizable (by modern standards) controller with only a single button and stiff w
Using An ESP32-C3’s RF Hardware For DVB-S2 Video Transmission
Generally the DVB-S and -S2 standards require a satellite somewhere in Earth orbit to provide a signal to receive, but you can also transmit your own DVB-S2 stream with any RF transmitter if you
Tiny E-Paper Display Delivers 30 FPS Of Game Boy Fun
Slow refresh, ghosting and low-contrast — wait, are we talking about passive matrix LCDs, or e-paper displays? That might be why e-paper Game Boy emulators are a thing: the limitations of the
2026 Hackaday Supercon: Workshops Are Open!
Supercon is Hackaday’s annual gathering, and you absolutely need to be there. Today, we’re pleased to announce our lineup of workshops, and it’s more than we’ve ever offered
DIY Force Sensing Joysticks Are A Cheap Way To Go
Traditional joysticks typically use potentiometers or hall effect sensors to determine the displacement of the stick itself when moved by the operator. Force-sensing joysticks are considered more d
What’s A Nonius?
If you already know what a nonius is, you can probably skip this post. But, if like us, you would have to look it up, we’ll tell you what we found out. It turns out, a translation mistake tau
Testing Oneself For AI Slop
The feed of a Hackaday writer brings many surprises, some rubbish, and the occasional diamond which of course we bring to you. Sometimes a page catches the eye that’s not a Hackaday piece per
Rendering 3D Prints From G-Code
Your CAD software generally has some rudimentary tools for rending images of your parts, from simply-textured models to more photo-realistic options. However, those renders are of the geometry you
Does It Run… Duke Nukem 3D?
When id Software released DOOM back in 1993 it helped define the genre, but it was hardly the only hit first-person shooter of that decade. There was also 3D Realms’ 1996 Duke Nukem 3D, a gam
2026 Retrocomputing Challenge: USBSID-Pico Has Two SIDs, Many Inputs
We’ll give you three guesses what the most important bits of silicon in [LouD]’s USBSID-Pico are, and two don’t count. Yes, there’s a Raspberry Pi Pico, and a pair of the un
JawnCon 0x3 Kicks Off In Philadelphia This Friday
Philadelphia’s homegrown hacker con returns this weekend, and this time it’s starting a day early to pack in even more talks, demos, and activities. Tickets are still available for anyo
ESP-SDR Can Now Transmit
Well, that was fast! Last week, we reported on two apparently simultaneous hacks using the 2.4 GHz radio inside many ESP32 variants that enabled raw access to the radio samples, turning it into a l
Using A Waffle To Check The Health Of Your Wii U’s NAND Flash
Game consoles tend to have a weak spot or two that will take certain units out sooner than they would due to normal parts aging. In the case of the Wii U it’s the eMMC storage IC with the con
Counting The PET Bottles Needed To Make 1 Kg Of Printer Filament
In countries where PET bottles do not get slapped with an additional fee that induces you to return it for recycling and said fee back, the resulting piles of discarded bottles have led many enterp
The FPGA Chronicles: Ready To Probe
In the last few installments, we looked at using the Tang Nano 20K with both the GOWIN tools and some open-source tools. The open-source tools certainly had the advantage of letting you simulate an
