Card Access to EPICS Design Build Lab (ARMS B103)
by Martinez, Jorge L 07 Mar '18

07 Mar '18

Dear EPICS students, My apologies, Purdue is upgrading the card readers and the one for the Design Build Lab was changed ahead of schedule. While the new card reader is programmed, please use the card reader in the Unclean Room (ARMS B097) to access the Design Build Lab. We are hoping this inconvenience won't last long, as the plan is to have all readers changed by the end of the week. I would like to take the opportunity to let you know that with access to the "Unclean Room", all spray painting should be done now in B097. Please ask for help when needed to show you how it is turned on and off. Please do not use the fume hood in ARMS 1098 any longer for spray painting. We will be relocating one of the flammable cabinets from 1098 to B097 to help with storage of spray paint. You can still use the fume hood when dealing with other chemicals requiring ventilation while handling. Thanks, Jorge Martinez EPICS Lab Manager Neil Armstrong Hall of Engineering - Room 1210 Purdue University 701 West Stadium Ave West Lafayette, IN 47907 +1 765 494 0629 +1 574 214 9450 (mobile) mart1419(a)purdue.edu<mailto:mart1419@purdue.edu> https://engineering.purdue.edu/EPICS

Re: [Epics-india] EPICS India: Acrylic

[cid:947b7771-9470-411e-adc4-639996bbc0c8] [cid:cbf6bb26-57e0-4462-8dbb-7b0b9e184cf4] Hi sir, I wanted to give you give you some additional information about the email we sent out earlier. Our team has finished prototyping our design and with our reviews from the past design review, we are hoping to deliver within the next 4 weeks. Thus, the primary priority is time. We need a device that looks like something in the pictures attached. (The models aren't dimensionally accurate) It is just a very rough sketch of what we are hoping to achieve and the two options we have to make that would be to 3D print them (in parts, with a total of 5 individual parts) or use acrylic sheets and shape/cut them with laser. Right now, we are looking at both the options while we work on the accurate 3D model and go with whatever option we find to be the least time-consuming. We decided to email you as we were told by the EPICS office that you could let us know if there are any acrylic sheets that are already available for use. From our calculations, we will need a minimum of 2x (1m *1m) sheets. So we are looking for sheets around that sizing. As for color; we are leaning towards white/black/silver (or grey) but we would opt for whatever would take the least amount of time to get. So the purpose of this email is to get a general understanding of how long it would take to get the material we have mentioned above so we can decide between printing them or cutting them. We would like to thank you for taking the time to read this and greatly appreciate your assistance in this matter. Thanking you, Rahul Maheswaran Project Manager | EPICS INDIA ________________________________ From: Martinez, Jorge L <mart1419(a)purdue.edu> Sent: Sunday, February 25, 2018 2:58:04 PM To: Zaina Mae El-Demerdash Cc: Rahul Maheswaran; Lauren Nicole Comer; Alexis Jane Marks Subject: Re: EPICS India: Acrylic I am assuming the acrylic is not needed for 3D printing, as we only use PLA. We should have enough PLA in the lab for 3D printing. At this point there is no acrylic in back order. The best route would be the team ordering what is needed. Lead time would depend on size and vendor. There are multiple sources, and the material is very common. Has the team determined what is needed? Please see me if you want to discuss further.

Tasks for the coming weeks - EPICS INDIA Spring 2018
by Rahul Maheswaran 24 Feb '18

24 Feb '18

Hey everyone, Great job with the design review and all the comments we received. This is a sum up of all the things I mentioned on the groupme, but I will make it clear and put it up here so that you can save this mail take a look at it if you are unsure. I will apologize if everyone feels overwhelmed by the number of things you are responsible for, but we need to stick to our schedule and take into all the complications that we will face during the next steps. Next steps : Modeling the new casing - Zaina and anyone else who wants to help her. Please drop an email to Mr. Jorge about the acrylic (email : mart1419(a)purdue.edu<mailto:mart1419@purdue.edu> ). Since this is going to eat up the time we have, we will be working on the final model WHILE we get a final word from him. If autoCad is not working, try sketchup. You can get assistance from Kelsey if you run into any issues or need some oversight into your design. If SketchUp doesn't work, then we have Solidworks and so on. Note: I am positive with the 3D model printing as we have the resources at our disposal and we will only need the modeling to be completed. If you think otherwise, let me know why. ATTACHING THE CASING: HEAT INSERTS FOR 3D models looks promising and easy to use. Printing the casing - Rahul I will be responsible for printing all the pieces and we can all work together in attaching them. We will be using the heat set inserts made for 3D printing, along with a screw and attaching them together physically. This is cost effective and less time consuming than making snap-fit joints Wiring the new model and building a backup circuit - Rahul - Once again, I will take responsibility for this and make sure we have the model working. Website - Lexi - You will need to get the website updated ASAP Testing - Lauren - Lauren, I need you to email (ASAP) Prof. Carla Zoltowski(email : cbz(a)purdue.edu) and ask her if we can go ahead with the testing process(not sure if she will contact them for us or she will give us the contact information)/ get any contact information so we can contact them and check the availability. This needs to be planned well ahead of time so we can get everyone's availability and start getting the model ready for testing. Worst case scenario, we will be testing with the wooden prototype and we can account for the feedback in the final model. Safety - Lauren/Lexi - I need the both of you to look into what sort of safety regulations we will have to worry about (if any) and start coming up solutions for it. We around 4 weeks before scheduled delivery and we need to get all of this done before that. I know everyone has exams coming up and classes are getting hectic, but we will need to plan every single step out in advance and execute it effectively. Each person should start working on their tasks and make sure you have a back up/ Plan B/C for each step. If one of those ideas don't work, move to the next one. Time is precious. If anyone has any other question, please email me or text me. Thanks, Rahul Maheswaran

Fwd: EPICS India: Help with buttons and Arduino

I’m guessing you have the wrong circuitry. It’s a bit hard to explain, but I’ve attached some picture of the buttons from the project we are working on. Generally it should be set up like this: Input: Positive pin, front pin (the one sticking out in front) Output: ground pin, bottom pin If you are using a resistor it should be connected to the bottom pin as well This is the setup for a basic button circuit. In the picture I sent you, the input is # 13, and the output # 6.

I just wanted to let you know that it's highly possible that the problem primarily revolves around the button's leads. Our initial circuit was using a simple tactile Arduino button (the tiny black ones) The circuit response was as expected and everything worked fine. The issue we are having is that after wiring the button to the circuit (a simple one, as seen in the code attached) when we use the serial monitor to monitor everytime it's pressed, it either goes haywire or doesn't register at all. When we replaced the same button with the tiny one, it works fine. I'd really appreciate it if you could take a look at the code attached (picture) and let me know if you spot anything wrong outright. Just to make it easier for you understand, the code attached involves an Arduino and the button only. It will increase the count from 0-4, by an increment of 1, every time the button is pressed and then resets to 0 and loops all over again.

They should integrate into your circuit without a problem. I’ll admit that if you don’t have a lot of experience with circuitry, pushbuttons with LEDs can be tricky. It’s a little hard for me to help you any further through email because the problem is likely in your code or circuitry. My advice would be to build a simple circuit with one pushbutton and basic code in Arduino. That should give you a better idea of which leads should be connected to where. Alternatively if the LED is flashing at all or just seems wonky you may have the leads switched or may need to add a resistor. It’s hard for me to be any more specific through email not knowing what exactly the problems are. If you are still having issues integrating, I’d be happy to take a look at your code or circuitry if you send me files/pictures. Please feel free to ask any follow up questions you have.
