I am not sure if this will pique your interest but I find kinetic sand tables really fascinating. Sisyphus came up with it first and there have been a number of open source implementations in due course. One way is to implement it using a scara arm mechanism but they have the problem of load weight in the case of long arms.

I came across this design that rethinks the design using an elegant rack and pinion arm but still needs a belt that may go out of calibration over time. This looks to be improved further using [two, concentric rings] (https://frew.io/work/sisyphish) but this design is not available to explore/copy.

I have no idea about 3D designing, but I would love to create a table one day: something that will not need constant adjustment. If you get around to taking this up, I would love to see what design improvements you can come up with.

You can’t just say that and not post your version.

Someone had to do it, so here it is, copied from that place that we have now left:

One morning to spice things up, teacher decided to have a classroom drawing project. One person would start, then the next student would add to the drawing. She asked the students who wanted to start first, so little Johnny raised his hand. Knowing little Johnny had a disturbed mind, she decided to pick Suzie first.

[“I drew a box on the ground!”] (https://i.imgur.com/PicyJVo.jpeg) Proclaimed little Suzie.

The teacher said it was a great start, and asked the next student to add on. Ignoring little Johnny teacher chose Billy.

“I turned the box into a house!”

The teacher thought it was wonderful, and went on to Timmy.

“I added the sun to shine down onto the house!”

“Excellent” replied teacher. Still ignoring Johnny the teacher chose Jenny next.

“I added some snow on the roof because it’s been such a snowy winter!”

By this point like Johnny could barely control himself. Teacher thought there was no way Johnny could ever turn this into a dirty picture, so he allowed him up to the chalk board.

“This is my dad bending over in the shower to pick up the soap!”

Thanks, I’ll look into them.

For Hawwa and Aimina watch it on a large screen up close when you’re high.

May I have a large container of coffee right now?

The biggest challenge i faced was getting the pH and nutrient right. The pre measured hydroponics nutrients were only available online to me at a big premium over big bags of similar sounding stuff like NPK, micronutrientes at local stores that sell them for farmers. I read up as best I could, found calculators, weighed and measured doses but I failed and my dear tomato saplings wilted in hours before my eyes.

I half assed in trying to build a hydroponic system a few years ago. Looking at this video, i realise how much effort it takes. But it must be so rewarding.
