I like making something by myself" that is called "DIY".

The reason is that I am a hunks rather than a creator.

The main reason of the persistence of "DIY" is for a satisfaction that I can save money.

For example, I can make a PC desk by one cheap veneer board, and install local area network at home by myself. All of racks in my house were made by me.

By the way.

Recently, I know that EtherCAT slave base which can be installed in Raspberry PI is sold for 6000 yen.

at a country in Europe

No matter where it is sold, of course, I want to get it. However the total cost (including shipping) become more than 24,000 Yen. So I had to give up.

I also tried to check the cost by my company system, the price come to be same.

I hope that I want to make the cheapest EtherCAT slaves, based on Raspberry PI by DIY, But this is meaningless for this cost.

Of course, If I start to study about the hardware design and production now, I will make it. However, I had run away from the hardware technologies because the design and trial was always annoying me when I was a college student.

Well, I think that this though was not wrong.

Thanks to enormous performance of microcomputer IC, many technologies has been realize by software(like farm ware and operating system)

However, EtherCAT realizes "Zero buffer transmission" which is ultimate realtime communication

No matter how hard it can be done with software, software cannot realize beyond the performance of hardware.

I like "DIY" for everything, however, the cost for "DIY" is more than a thousand times than commercial products. it will get my priorities wrong.

So, (this is very rare for myself because I adhere to individual activities, however) is there anyone who made your own EtherCAT slave for Raspberry PI?

Let's join me.

I think that I can introduce the place for presenting the results - probably
