Immersive Cursive: Growing Up Loopy

Growing up, ours was a family of handwritten notes for every occasion. The majority were left on the kitchen counter next to the sink, or in a particular spot on the all-purpose table in the breakfast nook. Whether one was professing their familial love and devotion on the back of a Valpak coupon, or simply communicating an intent to be home before dinnertime, the words were generally immortalized in BiC on whatever paper was available, and timestamped for the reader’s information. You may have learned cursive in school, but I was born in it — molded by it. The ascenders and descenders betray you because they belong to me.

Both of my parents always seemed to be incapable of printing in anything other than all caps, so I actually preferred to see their cursive most of the time. As a result, I could copy read it quite easily from an early age. Well, I don’t think I ever had any hope of imitating Dad’s signature. But Mom’s on the other hand — like I said in the first installment, it was important for my signature to be distinct from hers, given that we have the same name — first, middle, and last. But I could probably still bust out her signature if it came down to something going on my permanent record.

While my handwriting was sort of naturally headed towards Mom’s, I was more interested in Dad’s style and that of my older brother. He had small caps handwriting down to an art, and my attempts to copy it have always looked angry and stilted by comparison. In addition, my brother’s cursive is lovely and quick, while still being legible.

(Mostly) Harmless Houseplant Wields Machete

In a straight fight between a houseplant and a human, you might expect the plant to be at a significant disadvantage. So [David Bowen] has decided to even the odds a little by arming this philodendron with a robot arm and a machete.

The build is a little short on details but, from the video, it appears that adhesive electrodes have been attached to the leaves of the recently-empowered plant and connected directly to analog inputs of an Arduino Uno.  From there, the text tells us that the signals are mapped to movements of the industrial robot arm that holds the blade.

It’s not clear if the choice of plant is significant, but an unarmed philodendron appears to be otherwise largely innocuous, unless you happen to be a hungry rodent. We hope that there is also a means of disconnecting the power remotely, else this art installation could defend itself indefinitely! (or until it gets thirsty, at least.) We at Hackaday welcome our new leafy overlords.

We have covered the capabilities of plants before, and they can represent a rich seam of research for the home hacker.  They can tell you when they’re thirsty, but can they bend light to their will?  We even held a Plant Communication Hack Chat in 2021.

Electric Guitar Shocks You For Missing A Note

Rocksmith is a popular video game that works like Guitar Hero, but with a real guitar. You have to play well and hit the right notes, or the game penalizes your score. [Lightwing] took the stakes up a notch, though, adding a system that shocks the player every time they fail.

To achieve this, it was necessary to detect when the player missed a note. Initial attempts involved using Tensor Flow AI to detect the game state from the screen, but it was unreliable. Instead, the game’s memory was read to achieve detection. When the player misses a note, a certain section of memory changes, and a script reads the change in game state. It then sends a signal to an Arduino which triggers the stun gun’s fire button, which shocks the player holding the guitar.

As you might expect, the documentation for this project includes a video which involves plenty of gratuitous electric shocks when [Lightwing] makes mistakes. Fair warning — there’s plenty of colorful language when the stun gun fires. Generally, a powerful shock ends with screams a dropped guitar, and too much fear to continue.

It’s painful enough that it’s probably not a useful teaching tool for learning the guitar. We’ve seen similar shocking builds before, too, like this simple wire game.
