content: Hi, I am an industrial designer, graduated from Brunel University, UK, 2004. I am embarking on a project to make an exciting ice cream brand. I have designed and manufactured a prototype instant ice cream machine that makes extra yummy ice cream in about 60 seconds per portion. I have hard wired all the motors and valves into the machine.I am now making ice cream machine mark II. This will be mounted to my ice cream cart so I can go into public areas and actually sell my ice cream. The current prototype is controlled by 4 switches and 2 voltage regulators pots. It’s a bit like playing a musical instrument (Badly). I'm looking for someone who has the equipment and is willing to make a PCB and PIC programme so that my machine can be fully automated. I’m a start up business so have very limited funds if you interested in helping custom creams become a success I would be able to pay a modest sum to who ever is willing to help with prospect of further paid work when I start trading and have real capital to make my Mark III machine.I have basic knowledge of electronics. I actually designed, made and programmed a very similar set up 7 years ago although back then I had the luxury of university lectures and technicians to help with the code and schematics etc. I know how to communicate exactly what I need it’s a pretty simple project for someone who has good knowledge of PCB design and programming.I will now try to explain what I need in whiting as I don’t think I can attach a diagram to this post.I have 4 inputs and 5 outputsInput 1 Push ButtonInput 2 Push ButtonInput 3 Push ButtonInput 4 Micro SwitchOutput 1 12v DC motor 660ma MaxOutput 2 12v DC motor 660ma MaxOutput 3 12v DC Maxon Motor and Control amplifier (analogue control 0-5v)Output 4 12v DC solenoid valveOutput 5 12v DC solenoid valveI have the PDF data files of all components I can send and detailedI would like to use a 12v leisure battery to power all of these components. The programme will need to turn each of the 5 outputs on for certain amount of time depending on what push button is pressed. The micro switch is a position locator for a cam.For full details or to talk to me about this request please email me using customcreams@gmail.com. I am based in Berkshire UK but am willing to travel to meet and talk face to face about this project. Any suggestions would very much be appreciated.Thank you for reading this post.

content: For a one off (and even a few off) job like this you would be better off with one of the small PLCs like a Siemens Logo.

content: For simple stuff like turning on a motor for a certain amount of time after a button is pressed, I suggest looking into Time-On Delay Relays, and Time-Off Delay Relays. The micro switch, if used to turn of a certain function, could be wired in series, or a time-off delay. So far, although I do not know the details intimately, seems like it could be done without the use of any micro or plc based system. Feel free to pm or post more details so I/we can assist better.
