Steven Weinberg's advice for young scientists

A wonderful day at #makerfairevienna . Got advice to improve my soldering. 👌Put my hands on really hard transparent resin models.🤩 Smelled recycled ABS.🤔 Suprised that sewing machines have touch Interfaces and USB port. 👌Talked about self driving cars and rocket science 😎

Setup a plant watering system. It uses a capacitative moisture sensor for the soil. A dry level is used to start watering with a pump. Finally i put everything in a box.

Spent some time with #openscad and the #threads library 🤔. Built PCO 1881 caps used with soda bottles.👍Used what I have learned to built a threaded cap for my preffered hazelnut cream glass 😎

Model of my sun tracker sensor in #openscad. Used it to create a case - bottom and top - for it. Needed some iterations to get a fitting printable model. 😎

Got my first robot car that worked 'out if the box' 👌. Only had to get some 18650 recharchable batteries 🤔. Built a recharger and case. 😎

Resoldered and rebuilt a 4WD robot car platform I bought some time ago from #xiaogeek . Added an #Adafriut motor shield on an #Arduino Uno.👍 Had to solve a (well known) timer issue with motor shield and IR receiver 👌. Now I have another robot car 😎.

Got this Dominator IR controller of a wall climbing car.🤔 Analyzed the IR data sent by the device.👍 Now I can use it with my robot cars.😎

Built a self driving obstacle avoiding car. It uses 3 ultrasonic sensors to detect obstacles. Assembled a pcb to share a single trigger line for the sensors.😎 The position of the left and right sensor are not optimal. 🤔 To power the car I upcycled batteries of an old laptop 😁

Rebuilt a line follow car with my robot car kit. 👍Designed a holder usable with various kits in #openscad. Designed a course and pattern with #inkscape. Built the course with black paper.😎

Rebuilt a quadruped robot with 12 #mg90s servo motors. It stands still, swings it's shoulders and performs push ups. 🙂 The model of this rebuild was originally designed with balsa wood. 🤔 I made it with 3D printed parts designed in #openscad. 😎

Built an ultra sonic distance core. Distances are rounded to 5 cm and shown on a led bar. The closer you get, the more leds light.🙂 Made this to refresh my #vhdl and #icestick tooling knowledge.🤔 Back on track again 😎

Animation of different #quadruped ways of walking in #openscad Animation 1. Walk Leg movement front left, back right, front right, left back. Body is moved after 2nd and 4th leg movement.

Animation of different #quadruped ways of walking in #openscad Animation 2. Trot Leg movement front left and back right sync, front right and left back sync. Body is moved after each leg movement.

Animation of different #quadruped ways of walking in #openscad Animation 3. Passage Leg movement left legs sync, right legs sync. Body is moved after each leg movement.

Animation of different #quadruped ways of walking in #openscad Animation 4. Hop Leg movement front legs sync, back legs sync. Body is moved after each leg movement.

Animation of different #quadruped ways of walking in #openscad Animation 5. Gallop Leg movement left back, right back and front left (almost) sync, right front. Body is moved after each leg movement.

Finished a WIFI controlled car sample provided by @randomnerdtutorials. The ESP32 works as access point here 🙂. Mounted on card boards to keep it simple 😁.
