content: Do you have a specific questions to ask regarding electronics in regard to your dispenser?No one here is going to design this for you but most would be willing to offer suggestions regarding an existing design.

You decided to copy a nine year old project, passing it as your own idea.Quote from: savi on June 20, 2014, 11:31:46 amSo it turned out that copying that nine year old project wasn't as easy and simple as you thought. Tough luck.

content: i am going to design Automated medication dispensing system. for this i am using 3 Stepper motor, 1 DC motor, 3 Proximity sensor, 1 temperature sensor(LM35), 1 Fan, 2 LVdti want to design PCB for that ..please help me..i download PCB software(eagle).i have started but issue is what i need to draw schematic diagram..

content: Quote from: savi on September 19, 2014, 08:24:48 amCorrection....."youdreamto design a Automated medication dispensing system"......and before you do, you need to realize that some of the most experienced members of this board wouldn't touch that project with a 10 foot pole.Not to burst yoru bubble, but figuring out eagle is the least of your worries. My advice is to start small. I assume this is some kind of automated pill dispenser? Ya know, replace grandma's pill box with a machine that will dool out the pills for the day? Heck, even that could be deadly. I like your grandma! I don't want you to kill her if you mess up the build!

content: I kind of hesitate to keep this thread alive by posting to it it but oh well...You have not given enough information (the link in the first post does not work for me anyway). So you got 3 stepper motors one dc motor 3 proximinity sensors one temperature sensor and 1 fan. What should these components do. What are their specs. Slap 24V to the fan and it will run or burn if thats too much for it. Stepper motorts will turn when you give pulses to them but how much should they turn what kind of load do they face. What is the purpose of proximinity sensors. You should give some info about what the mechanical design is. What is the power source for the cirquit. Direct line AC, batteries or something else? how much voltage and current does it give?You say you have no experience in PCB design because of "shortage of time" Well how much time you do have. because if it is only 2 weeks you are going to fail unless you hire electrical engineer to do the design for you.PCB design is only the last step. You need to learn to design circuit (schematic) design PCB and program the microcontroller (learn C). There are tutorials for all of these of course. But for all of them together with no starting experience i would recommend EE program in some university. Which seems to be what you are doing. You should tell your teachers that you are way over your head in this assignment and ask them what are the proper entry level courses for learning the skills mentioned above.

content: Savi, this forum is amazing and populated by many talented persons with a lot of knowledge (of course not me!), but It feels like you not even know how to start and you're asking for some kind of "free lunch" ready-made schematic for you're project. (maybe I'm wrong)If so,Quote from: george graves on September 19, 2014, 08:31:54 amis damn right. It's dangerous.So if you're new to this kind of projects, follow the advice to start small.

content: I'll design the board and program the microcontroller for you, under one condition:Once it's complete and working, you have to fill the dispenser with a bottle of each of the following: hydrocodone, lorazepam, carisoprodol, clonidine, diphenhydramine and amitriptyline.Now, you have to test the dispenser by activating it and consuming what it dispenses until it's out of pills.Did it work? Celebrate by drinking a fifth of vodka!Let me know if you'd like to take me up on this.Sent from my Smartphone

content: I do not think he will be in any condition to drink the vodka after that cocktail. Only thing you left out was some sidefanil, to keep him from falling onto the floor.
