The next module is the rotary table. This module is responsible for moving the glass from position to position, in which each other module will do its job... It will move the glass under the sugar and coffee dispenser, then under the water, the shaker, the water again, the straw dispenser and finally it will bring the glass in front of the user to get his coffee...
Christos Polidorou offered again his CNC machine to make the pieces. Thanks Christos!
With a file i cleaned the pieces from wood remainings
I cut a piece with a rubber wheel mounted on a 5mm axis, taken from an old photocopy machine
These wheels comes with plastic bases. I used two of them to fix it in a pocket designed for this
Then i screwed a big 90mm gear on the other center of the wooden rotary table. The gear comes again from the photocopy machine.
Looks like that the coffee machine will be a recycled photocopy machine. The shaft comes again from this photocopy machine!
The rotor of the rotary table is almost ready. Time to make the stator:
First, the ball bearings that will keep the shaft of the rotor stable...
The ball bearings are fixed int the special pocket that i machined on the bearing base piece
Then i put the rotor under the hole of the coffee maker base, right in the center of it!
I put the bearing base along with the ball bearings in the shaft of the rotor
And i screwed the bearing base onto the coffee machine base...
This is how it looks from above without the rotary table
And then, i had to find a way to move this rotary table around...
This is a stepper motor base, again from the old photocopy machine
I removed the rubber bases, and with a hammer and a vise i straightened it
The motor comes from the same source... It is a unipolar hybrid 2-phase stepper
I fixed the base onto the motor
And the whole construction was screwed on the coffee machine base
@Alex In Greece during the Ancient times there was this saying: "Oyden monimoteron ek toy prosorinoy" which means that "nothing is more permanent than the temporary".
But now that you said that again, i think i should restart this project, shouldn't I? Hopefully within this year.
Hi you have a nice coffee Instant Cold Coffee Machine but you wanted to use a fridge for cold water but no water cooler that you use waron also in coffee automaaten is where you can get I know old water out of if not the name but it can look for you we have that built-in devices greetings alex
Hello George. Regarding the elements, these are hardware wiring to indicate wire connections between the modules. The orange boxes indicate wires coming from the output module (Digital Output Module - DOM), and the green indicate wires going to the Digital Input Modules. Notice that for example, from module "Rotary table", 4 wires comes out, then 2 of them arrive from the DOM and 2 goes to the CPU.
As far as the diode is concerned, this is only for polarity protection. It is the same as the D2. But you are right, It is not necessary and i may not put it after all.
I think your architecture diagram (first figure) is slightly confusing, because it seems to include elements of code (the elements above the CPU) with hardware elements. Ideally, you would have a system-level block diagram detailing your hardware and a separate functional block diagram to describe your code. If I'm misreading your architecture diagram, feel free to ignore this.
Secondly, looking at your reset circuitry, I see you have a 1N4148 diode between your microcontroller pin and your ICSP header (pin 1). I'm fairly certain this diode is not necessary, so you may want to double check that.
Frappé has become very popular here in the States. The difference is we use fresh coffee grounds to make coffee then we chill the hot coffee. But we tend to make more fresh coffee here while Europeans tend to make more instant coffee.
To serve we pour some in a glass and add chipped ice.
We also tend to add flavors to our frappé in the States. We can't leave a good thing alone - we have to tinker with it to make it more sellable.
