Check out the first steps of my strandbeest!

I have a couch in my workshop and it left an empty corder. I figured it would be the perfect place for a nightstand. Me being in my woodworking phase I decided to make one myself. I think it came out looking better than anything I could have bought.

Ich habe ständig vergessen, welche Tonne an welchem Tag rausmuss, also habe ich mir ein kleines Gerät gebaut, das mich daran erinnert.

So funktioniert es: Ein ESP32 holt sich die Abholtermine aus einem Google-Kalender (über den privaten iCal-Link), rechnet aus, welche Tonne als nächstes dran ist, und lässt eine von vier 3D-gedruckten Mini-Tonnen aufleuchten. Ein OLED-Display zeigt pro Tonne den Countdown, also in wie vielen Tagen sie geleert wird, und kann auch anzeigen, wer diese Woche mit dem Rausbringen dran ist. Die Tonnen stehen über weißen LEDs im Deckel, dadurch leuchtet die ganze Tonne in ihrer Farbe.

Technik für alle, die es interessiert:

• ESP32 DevKit, vier LEDs über BC547-Transistoren geschaltet
• OLED 0,96 Zoll (SSD1306) über I2C
• Stromversorgung über einen 18650-Akku mit TP4056-Lademodul und einem MT3608-Step-up auf 5V
• Firmware in C++ (PlatformIO), komplett über eine Konfigurationsdatei steuerbar: Tonnen, Suchwörter, GPIOs und Vorwarn-Tage stehen alle in einer Tabelle, dadurch läuft es mit jedem Kalender, ohne die Logik anzufassen
• Gehäuse und Tonnen sind 3D-gedruckt

Weil die Regeln datengetrieben sind, kann man Tonnen in einer einzigen Tabelle umbenennen oder ergänzen.

Ich habe daraus auch ein ausführliches Bau-Video gemacht: https://youtu.be/p061BzUC5rA

Hi everyone,
I’d like to share the biggest project I’ve ever built.
Over the past several years I designed and built this full-size mechanical riding horse completely from scratch.
My goal was to recreate a realistic riding motion using woodworking, mechanical engineering and a simple drive powered by a standard drill.
Every part of the mechanism went through multiple prototypes before I was happy with the final movement. It took countless hours of designing, rebuilding and testing, but seeing it finally work made every setback worth it.
This project taught me more than any other build I’ve ever done.
I’d really love to hear what fellow makers think.
If you have any questions about the mechanism, design process or construction, I’ll be happy to answer them.

A project I'm working on needs a very small sliding joint, similar to what's in this miniature caliper. I'd like to scale things up eventually so I'm hoping to find a source where I can buy them, rather than have them all machined.... It would be an M3x3mm grooved pin. Can't seem to really find anything under 10mm online, though.

Showcase my 3d print chair

This is a 3D printed chair designed using topology optimization. The manufacturing process used six FDM printers and the chair was polished and painted carefully. I love this work because this is meaningful to my life.

Here is my design video. You will see how topology optimization generates this design. That was amazing 🤩!!!

I’m a beginner working on a small ESP32 e-paper project called “Excuse Cat”.

It’s a tiny desk companion that explains why my project is still not done. It starts on a home screen, then a button press enters the main screen and generates a random excuse with a matching cat expression. If there’s no interaction for a while, it returns to the home screen. The enclosure is based on other project, where I only make some adjustments on it through 3D printing. The codes are written in Arduino IDE.

Right now it’s USB-powered and controlled by one button. I’d like to make it more interactive, maybe with sensors for gesture, tilt, shaking, or picking it up, so the cat can react with different moods but I still don’t know how to solder yet.

Do you have advice for this project? (I'm also collecting some funny reasons for procrastination for makers.

Everything is welcomed. ;)

I designed this 3d printable mechanical expanding spinning top and I think it's great fun and wanted to share it!

Hey, so I recently started an Arduino project messing around with face tracking and some small displays. I’m about a quarter of the way through if I had to guess, but am going out of town to visit family on the 7th (Tuesday) and will be flying. I’ll be there for about 2 weeks and don’t really want to put the project on hold until then, so I figured I would look into taking it with me.

After doing some research, my plan is to check a bag and then try to organize all the parts as best as I can, taking out any batteries, and then attach a little note explaining kind of what I’m doing, and I should be good.

I figured finding a thing to store and organize my parts would be as simple as looking through Amazon and then finding one that matches the sizes and number of parts I have; however, that has not been the case. Everything I have found has either not been big enough, big enough for the bigger parts but at the cost of taking out like 3 of the total spaces and not having enough for the rest, or just won’t be here before I leave.

Worst case scenario, I can just run to a sporting goods store near me and probably pick up a tackle box that will work alright, but I figured I’d ask some people who are a lot better and have been around this longer than me.

The ideal solution would have:

1. Enough storage for all the parts to fit neatly in their own compartments, the biggest being the 830 point breadboard which is about 6.5 x 2.12 x 0.35 inches.

2. Have a few extra compartments of varying sizes for parts that I may order while away.

3. Double as a good organization tool for this project and future projects.

4. Not take up too much space in a suitcase.

5. Arrive or available to buy in store before or on the 6th.

6. Have a transparent lid so all parts can be seen without having to open everything

I’ve attached pictures to the top and have the links to the parts under this. Any specific recommendations and/or links would be much appreciated.

A few years ago, u/raceking37 and I decided to create our own digital watch. The project was inspired by a few vintage HDSP-2000 LED matrix displays that we had acquired. These displays were first introduced in the 1970s and have a really unique look, especially under a microscope (as shown in the last image). They're quite difficult to photograph with my phone, though, so they look much nicer in person than they do in these photos. The watch uses an ATTINY1616 microcontroller. The metal case of the watch is SLM 3D-printed in stainless steel. I also made a short video about the project.

This is the 20th anniversary of the OG Maker Faire, the one that started it all back in 2006. It's happening at the historic Mare Island Naval Shipyard. If you have a project you would like to show and tell other curious and creative people we would like to have you there. https://makerfaire.com/bay-area/

I'm not sure of this is the right channel for this but it is the best I could find. Other suggestions are welcome.

We have recently moved into a new home, which has high- and weird shaped doorsteps. Problem is, that our robot vacuum cannot climb these, but I would really like to make it work somehow.

They are pretty steep, so I guess that the ramp would need to be quite big as well, which means that they cannot be there at all times, which means that they would need to be taken off/on very easily. I have tried cardboard with antislip-mat with no success, it moves.

I will attach a sketch of one. In this one the floor is a bit higher in the other room.

I appreciate any ideas, particularly cheap ones!
