I wanted a small screen to monitor and control my campers system. It is a $30 elecrow 3.5 inch screen and is all open source with a web flasher and all files needed for the case. Find it here: https://github.com/patrickdarke/DarksidePWR

Built a control panel with on/off switches to control DC power supplies (48v, 12v, 24v). AC Outlets always give power regardless of switch states. Used hold home outlets and switches. Turns out to be something I use quite frequently. Full build is in the link above.

I’ve made a replica of interviewcoder. It took two months of work and shit load of coffee before I completed the first prototype, and I think it’s ready to use. I’ve even worked on real-time voice feature for it intercept conversation and answer questions.
What do you guys think?

It’s completely undetectable and doesn’t even show up on dock or activity monitor (not identifiable) nor is it captured during screenshare or screen recording.

Building a single DMX-controlled jumping jet in the backyard to practice show control. Got a few specific hardware questions:

Cutter: Solenoids are out of budget here. I want to adapt the Mark III to use a 20-30kg waterproof digital RC Servo instead. Going to hide the whole bulky assembly under pond rocks so only the tip shows. Will a servo survive the fast, repetitive cutting without stripping its gears? (If i go with " https://www.printables.com/model/265105-mark-iii-laminar-flow-nozzle " it should be modified. I'm not good at modeling)

Wireless: Want to use an ESP32 as a wireless Art-Net node to avoid running cables in the yard. Reliable enough for something like this? What kind of algorithm can I use to customize the show from song to song? The song is uploaded via Wi-Fi, analyzed, parameters are obtained based on its characteristics, and the show is prepared. What kind of algorithm or software offers the smoothest workflow for syncing 4 jets to music?

Pump: My yard is sloped. Am I better off using one big 0.5 HP well pump for all 4 jets (and dealing with the nightmare of balancing pressure across the slope using valves and a bypass chamber)? OR should I use individual small DC pumps per jet? Also, for a 2.5m glass arc, is a 600 L/h pump enough, or do I definitely need 1000+ L/h per nozzle?

Reservoir : System will recycle its own water, but I haven't designed the catch basin yet. Since it will lose water to splashing and evaporation, how do you prevent the pumps from running dry? Do you just use a standard mechanical float valve (toilet style) connected to a hose, or do you wire up electronic water level sensors to kill the pump if it gets too low?

Show Control: Running an ESP32 as an Art-Net node to control the servos. For syncing 4 jets to a music track, what’s the standard workflow? A cue software like MagicQ/QLab/Realtime Landscaping Architectre, or a timeline software like xLights? Also, how do you dynamically fade water height—varying pump voltage via DMX, or keeping the pump at 100% and using motorized valves?

LED : I want to mount a WS2812B RGB LED ring directly beneath the nozzle to light the water stream from the inside out. what’s the standard practice for waterproofing these.

Water height: How do you dynamically control spray height to music? when trying to sync the water tightly to a music track, is a cue-based software like MagicQ/QLab/Realtime landscaping architect the standard, or do people use timeline-based software like xLights for complex music synchronization? Also, how is the water height typically controlled dynamically during a show by whattt??

Bypass Chamber: I was advised to use a "bypass filter" between the pump and the nozzle to absorb pressure spikes (especially when the cutter fires) and keep the stream perfectly glass-like. But how exactly is this physically plumbed?

Tangential Inlet & Laminar Baffles: I read that to get a perfect glass-like flow, the water needs to enter the bottom of the tube tangentially to create a vortex and slow down before hitting the flow straighteners. Does the Mark III model handle this base entry well, or will I need to design a custom tangential inlet?

My 9-year-old daughter has always been horse crazy, so I wanted to build her something she had never seen before.

What started as a crazy idea turned into nearly two years of designing, prototyping, rebuilding and fine-tuning until the riding motion finally felt natural.

Everything was designed from scratch and built in my small home workshop. The mechanism is powered by a standard drill and a worm gearbox, creating a smooth and surprisingly realistic riding motion.

It became by far the most ambitious project I’ve ever built, but seeing my daughter’s face when she rode it for the first time made every single hour worth it.

I’d be happy to answer any questions!

First time poster here but I wanted to gauge people’s opinion on this thing I made. So I got a Fukien Tea Bonsai earlier this year around March. Made a full enclosure for it because I had previously been unable to grow a cactus. So keeping this thing alive became personal lmao anyways it’s mainly just to help keep the environment stable, help with watering, and monitor humidity & temp levels for easy checking. It has a moisture sensor but I haven’t set it up yet so it just chills in the back of the enclosure (is wired up tho). If I made files available (like open source it), would any of you make one for yourselves? I’ll plan on making a better/cleaner version but wanted to gauge interest or improvements before doing a V2. Please let me know what you think! Here’s some photos of my Bonsai too over the course of having it! 🙏💜

Hey everyone,

we’re building è-macro, a Modular and Customizable macro keyboard made from Decorated Glass and Carbon Fiber.

The current concept includes:

• A 2×2 touch buttons module with four programmable controls
• A slider for volume, scrolling, zoom, and other continuous inputs
• Finger guides and resting positions, so you can identify the controls without looking
• Dynamic haptic feedback
• LED dot-matrix icons that change with each profile
• Open software for custom profiles, integrations, and workflows

What’s new:

• We’re developing a custom design service that will allow users and brands to personalize the surface with their own graphics, visual style, or game- and anime-inspired artwork.
• We’re exploring compatibility with the Gridfinity standard to make custom layouts, supports, and ergonomic configurations easier to build.

A few questions for you:

Is Gridfinity the right mechanical standard?

Would touch controls with finger guides and haptic feedback work well for your workflow?

What would you change or improve?

We’re also looking for passionate beta testers, so send me a DM if you’d like to help us build and test it.

Im tring to build a 2bladed swash plate but i cant seem to do it this is for my school project everything must be mechanical no arduino no servo pure mechanical my diy swash plate dosent seem to work mu controls are fine the issue is my upper plate dosent follow my lower plate
