A wonderful day at #makerfairevienna . Got advice to improve my soldering. ๐Ÿ‘ŒPut my hands on really hard transparent resin models.๐Ÿคฉ Smelled recycled ABS.๐Ÿค” Suprised that sewing machines have touch Interfaces and USB port. ๐Ÿ‘ŒTalked about self driving cars and rocket science ๐Ÿ˜Ž

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 ๐Ÿค”. Built PCO 1881 caps used with soda bottles.๐Ÿ‘Used what I have learned to built a threaded cap for my preffered hazelnut cream glass ๐Ÿ˜Ž

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. ๐Ÿ˜Ž

Got my first robot car that worked 'out if the box' ๐Ÿ‘Œ. Only had to get some 18650 recharchable batteries ๐Ÿค”. Built a recharger and case. ๐Ÿ˜Ž

Resoldered and rebuilt a 4WD robot car platform I bought some time ago from #xiaogeek . Added an #Adafriut motor shield on an #Arduino Uno.๐Ÿ‘ Had to solve a (well known) timer issue with motor shield and IR receiver ๐Ÿ‘Œ. Now I have another robot car ๐Ÿ˜Ž.

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.๐Ÿ˜Ž The position of the left and right sensor are not optimal. ๐Ÿค” To power the car I upcycled batteries of an old laptop ๐Ÿ˜

Rebuilt a quadruped robot with 12 #mg90s servo motors. It stands still, swings it's shoulders and performs push ups. ๐Ÿ™‚ The model of this rebuild was originally designed with balsa wood. ๐Ÿค” I made it with 3D printed parts designed in #openscad. ๐Ÿ˜Ž

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.๐Ÿ™‚ Made this to refresh my #vhdl and #icestick tooling knowledge.๐Ÿค” Back on track again ๐Ÿ˜Ž
