Supercon 2024: Using An Oscilloscope To Peek Below The Noise Floor

1 week ago | hackaday.com | Lewin Day

When you’re hunting for a signal with your oscilloscope, the stronger it is, the better. If it’s weak, you might struggle to tease it out from other interference, or even from the noise floor itself. You might wish that you were looking for something more obvious rather than the electromagnetic equivalent of a needle in a haystack. Finding hidden signals below the noise floor may be a challenge, but it needn’t be an insurmountable one.
Someone Turned An Old Dodge Viper Into A Ferrari Killer With A Terrifying Dual-Clutch Transmission Swap

1 week ago | theautopian.com | Lewin Day

The Dodge Viper has always been a fast and fearsome thing. So much so that Matt Hardigree once opined that giving one away on a game show was like signing someone’s death warrant. Still, the rate of acceleration was always held back by the driver’s ability with a stick shift. However, one shop has changed all that, giving the Viper a transmission “upgrade” to fling it ever faster towards the horizon. Remember the Getrag GS7D36SG?
Four Decades Ago, Mexico Got A Special Grand Wagoneer With A Weird Engine You've Never Heard Of

1 week ago | theautopian.com | Lewin Day

Jeep is a brand with a storied and well-documented history. There are diehard fans that can rattle off every engine ever sold in a flat-fender, or recite the differential options available on the XJ on a year by year basis. And yet, there’s one Jeep that is barely documented or discussed at all—a Grand Wagoneer that actually wasn’t really built by Jeep at all. Weird things happen when a far-off company starts building cars under license.
The Commodore 64 Gets An HDMI Upgrade

1 week ago | hackaday.com | Lewin Day

The Commodore 64 may remain the best selling computer of all time, but it has one major flaw. It doesn’t have HDMI! That makes it a total pain to use with modern displays. Thankfully, [Side Projects Lab] has whipped up an HDMI output board to solve this concerning oversight from the original designers. The project was inspired by work by [Copper Dragon], who whipped up a nifty RGB output board.
Nerf Blaster Becomes Remote Control Turret

2 weeks ago | hackaday.com | Lewin Day

For most of us, turrets that aim and shoot at things are the sole domain of video games. However, they’re remarkably easy to build with modern technology, as [meub] demonstrates. Meet the SwarmTurret. The build is based around an existing foam blaster, namely the Nerf Swarmfire. This blaster was chosen for being easy to integrate into the build, thanks to its motorized direct-plunger firing mechanism and electronic trigger.
LED Matrix Built For M.2 Interface

The M.2 slot is usually used for solid-state storage devices. However, [bitluni] had another fun idea for how to use the interface. He built an M.2 compatible LED matrix that adds a little light to your motherboard. [bitluni] noted that the M.2 interface is remarkably flexible, able to offer everything from SATA connections to USB, PCI Express, and more.
EMF Forming Was A Neat Aerospace Breakthrough

2 weeks ago | hackaday.com | Lewin Day

Typically, when we think about forming metal parts, we think about beating them with hammers, or squeezing them with big hydraulic presses. But what if magnets could do the squeezing? As it turns out—Grumman Aerospace discovered they can, several decades ago! Even better, they summed up this technique in a great educational video which we’ve placed below the break. The video concerns the development of the Grumman EMF Torque Tube.
Tearing Down And Hacking The T2S+ Thermal Camera

2 weeks ago | hackaday.com | Lewin Day

[Dmytro] was able to lay his hands on a InfiRay T2S+ camera. It’s a capable thermal imaging unit that comes at a cheaper price than many of its rivals. [Dmytro] decided to pull it apart to see what makes it tick, and he discovered a few interesting things along the way. Like so much modern hardware, pulling the case apart does require some spudging and levering. Once inside, though, it comes apart in a relatively straightforward manner.
POV On The Flipper Zero

2 weeks ago | hackaday.com | Lewin Day

The Flipper Zero can do all kinds of neat stuff, like helping you cut keys or decode various radio transmissions. However, until now, it hasn’t been particularly adept at persistence of vision tasks. For that very purpose, [Derek] built the LightMessenger. The LightMessenger is a hardware add-on module for the Flipper Zero. In persistence-of-vision mode, you can plug it in via the GPIO header and display messages in the air by shaking it around.
Tesla Owners Are Fitting Rear Door Ripcords So They Can Quickly Escape In An Emergency

2 weeks ago | theautopian.com | Lewin Day

If you’re in a car and it starts burning, you’re going to open a door and get out as quickly as possible. However, in some Tesla fires, there are concerns that vehicle occupants have perished when the electrically-activated doors have failed to open in an emergency situation. Now, some safety-minded owners have found a solution—installing ripcords in their vehicles for quick escapes.
