A few extra pictures: Lever with neodym magnet. https://live.staticflickr.com/65535/51462540032_e2b95e3da8_b.jpg HD picture on Flickr: https://www.flickr.com/photos/fotoopa_hs/51462540032 Expander for 15 GND connections. An alu tube of 15x15x1.5mm was used. 15 holes of 2.5mm were drilled at a distan...

It's a kind of magic. Wonderful. Although logically it must be magnetism, while watching it I thought, please don't show the back side, just let's keep believing in magic. Sooo nice to watch. Peter You're right. During the making of the video, the intention was already to show no direct solution. I...

Full Robopro program of the magic bullet track. As you can see 8 tasks running in the program.

I have uploaded some photos. https://live.staticflickr.com/65535/51452430712_054c7610eb_b.jpg HD on Flickr: https://www.flickr.com/photos/fotoopa_hs/51452430712 This is a frame from the video recording of the ball feeder. You can see here how a ball is recorded and transmitted. The feeder is powered...

Thanks Stefan and Ralf and atzensepp! Dear fotoopa, And i would assume that there is also a juicy FPGA behind the scenes. Am I right? No, Only the regular standard TXT Controller is used. No additional external devives, no I2C. So you can use it with any type of controller, even Arduino or something...

This ball track has something magical about it. The balls go gently up and then back down. The total height of the track is 720mm. Only a TXT Controller from Fischertechnik is needed. The assembly contains several thousand blocks. A few special blocks are 3D printed. Programmed with Robopro. A short...

Glad to see that your problem is solve and that there are still people who investigate the cause thoroughly and with expertise. Und jetzt noch ganz kurz: Der ATmega bekommt C-Code, das FPGA VHDL- oder Verilog-Code. Letzteres schließt nicht aus, dass im FPGA ein AVR installiert wird. Oder ein Z80, ei...

This project is absolutely amazing and we are curious what will come next. Thanks! What will follow has not been determined for now. I have already made so much that it will be difficult to find a new challenge. I have quite a few limitations because my eyes are getting very bad. That is also the r...

The input module for the pic and place robot is ready. This allows the robot to make a drawing. It uses the content of the neo-display to determine where to place colored disks. The content of the drawing can be loaded from the flash memory or created directly with the editor. The input module is pr...

You should probably contact Hackaday (.com or .io, it depends) about this project, they will definitely have a place for your work there. Thanks Rubem for the comment! Yes I know Hackaday. In 2008 they already wrote articles of "fotoopa". If you search for "fotoopa" you will still find articles. Cu...

As promised, I updated the Roboprogram to detect the colored discs on the robot table. Manually you can apply the discs to the table yourself. By making a scan we can read the drawing, display it on a color neo-led display and store it in the flash memory. Later we can upload the drawing again to ma...

Detection of the color disks with the USB FT camera. The camera is mounted on the pic an place robot arm. It is set to image a zone of 4x4 discs. The table consists of 8 of these modules. By taking 8 images the whole surface can be measured. In total, there can be up to 128 color disks. The camera m...

Testing the FT Battery 8.4V/1800mAh. In doing so, I start from a fully charged battery the day before. Without load the Vbat was 9.6V. I use a power resistor of 20 Ohms as the load. This makes the discharge current around 470mA as the starting value. I allowed the discharge to proceed until the batt...

Thanks for your reply. Yes there are many hours of work in the project. That was the intent, to make something to keep my busy. At my age, you have a lot of time. Originally, the project was intended to work with the FT steel balls. I had made the 3D prints for this purpose. They had also been made ...

Yet another update on the Pic and place robot. I further finished the Robopro program that allows the robot to scan the table and remove all the discs. Meanwhile, the full verilog lib function for flash memory is also finished. The editor is completely finished. New patterns can be drawn and stored ...

I hereby terminate my contribution with the DE0-nano soc. There are hardly any FPGA users, so my contribution makes little sense. The English language also appears to be a limitation for some users. I am going to limit myself to the information on my Flickr web: https://www.flickr.com/photos/fotoopa...

A new update: Colour pattern editor under Fischertehnik Robopro programme. Here is a picture of the neo-matrix display placed on top of the window of the FT programme. With the Robopro programme, you can only use a fixed colour to the LEDs on your screen via a constant value. When you run the progra...

Could it be that I am understanding only "railway station"? I am eager to learn but that is too fast for me.

That's why I suggested that you start with a simple board and a few blinking LEDs.

Yes that is a useful tip. That's also how I started years ago.

First test to have access to the spi flash W25Q64. Here I use the read ID command $90 to read the ID values. The chip answers nicely with the data $EF $16. I use the TXT via the I2C line for this purpose. Now I continue to implement the other functions. https://live.staticflickr.com/65535/5112501402...
