Starting a project isn’t difficult. Finishing is. Or as they say: the last 20% is always the hardest part. But no worries, today we’ll finish this project by working on the final details.
Since the prototype turned out to be a success, it is time to work on a more professional solution: a custom PCB. Of course I don’t just slap an Arduino and a MAX485 IC on a board and call it a day. I use this opportunity to add some nifty features to the custom board. You know, just to impress my dad.
So, it has been a month ago since my last blog post. Reason for this is the birth of my beautiful second baby boy, Luca! But after some quality family time, it’s now time to pick up the tinkering, and start making things! Of course we start easy, so this week I’d like to show you the beautiful power of 3D printing and how it helps me to be an awesome dad!
For both my automatic curtains as well as my robot arm joint I ended up using GT2 belts and pulleys. But although printing GT2 pulleys is possible, the 3d printed pulleys tend to skip some teeth quite easily when they are used in high torque applications. Just as an experiment I though to give HTD 5M belts a try.
Ever since I have my own company I wanted to have a PCB business card. Of course I wouldn’t be the first, but it would definitely give a nice touch to my company’s identity. And since I wanted to give KiCad a good try anyway, why not go for it?
In the last few weeks I mostly focussed on the aesthetic of my Robot Arm project. Now that I finally received the necessary gears, It’s time to work on the transmission box.
