Instant Cold Coffee Machine




Worklog - Heading for the first test (May 23 2011)

So, i have almost everything needed to run a first test. All i have to do is put them together. First, i have to get some kind of temporary water supply...


I put a T water connection between the water supply and the sink. I also added a ball valve. Then, i connected 10 meters of water hose from the ball valve to the input of an electromagnetic valve I connected the output of the e/m valve to the input of the flow counter. A hose from the output of the flow counter is mounted onto the shaker.


After the water supply, i added the power supply. I will use 2 different supplies, one with 3.3, 5 and 12 volts for the loads (motors, valves, LEDs etc), and one for the low power electronics (sensors, motherboard etc).






I mounted the motherboard on the back of the machine Then i got an old PC PSU and opened it... ...and i removed all the entrails
After cleaning and drilling the base of the PSU... ...I screwed it under the motherboard I covered the PSU and i screwed another 5V PSU

      • Still watching this space every other month only to find the project still not being updated. Hoping to see some progress soon. :)

      • re si, nomizo the "redux" version should have an optional milk stage too for those of us who prefer it a bit easier to drink :)

      subscribed on YT, keep up the good work!

      • @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 ,

      Great work . From where did you buy the worm gear extruder ? Can you give me a website for that .

      Many thanks

      • 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

      • @Fung no of course not. i will have different programs for different sizes. there are 4 sizes of cups (in respect to the volume)

      • Do the cups which being used are restricted to the same size and same volume? (ie other cups are not allowed?)

      • Congratulations man!
      Awesome machine!
      Can you tell me, where did you find the 'worm' thing
      for the dispenser mechanisms?

      • 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.

      • Why does PIC16F1937 have 2 Vdd's and 2 Vss's?

      • 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.
