I don't know much about SAN vs MABS. I'm not really a plastics guy, yet... I've made panels before from machined acrylic and now I have a requirement for a panel with a shape that doesn't lend itself to machining very well and I've found myself in the midst of finalizing the design on an...
I'm working on the design of a plastic part that will be painted black in a matt finish. What should I specify for the surface finish? SPI C-1? The reason it being painted is because its a backlit display panel so it will need to be translucent to carry light to text and graphics. Clear part...
I'm working on the design of a control panel that goes in a vehicle that is approximately 6" square with the front face having a 2" by 6" area being flat that will be an arms reach from the operator. The part is going to be injection molded. On the reverse side of the flat area there are...
I played around with a demo version of David Laser Scanner using a cheap webcam and a projector a few years ago I was using a really cheap webcam so the results were not that great but looked promising. I have an upcoming project where I need to make a design work with an existing product. I...
Thanks for the feedback. I agree with both of you. My first choice is micro usb. I really like building off of standardized things that work and people use/readily available. Since my choice to use micro usb was vetoed because of concerns with debris getting in the usb port and not wanting the...
Hi,
I'm working on a consumer device with a small rechargeable battery. I have just enough space for a micro usb/usb c connector. I would like to use a magnetic detachable connection. Rather than coming up with something from scratch does anyone know of any open format designs with a similar...
I added a graphic to the original post, its just a crude mach up that is similar to the design I am working on. Let me know if its not clear and I'll clarify with a better drawing.
Now that you mention it I think you are right. 70 shore A is probably way to hard for this to slip on. As far as I...
I'm finishing up a design for a consumer product that someone else started. Can't share the specific details unfortunately. I have a nylon part that has a 35mmx49mm footprint with a radial brim flush with the bottom that sticks out 1mm and is 4mm tall (from the bottom). All the corners have a...
I misspoke in my original post and have since edited it. The desired function is to have an LED turn off when a magnet is close and turn on when the magnet goes away.
The TI application note IRstuff shared has a super impressive battery life. Unfortunately as far as I can tell reading the data...
Adjusting the location of the reed switch would be troublesome to incorporate into the design but an adjustable iron pole could be a great solution. Thanks for the idea!
Yes I agree a very tiny budget hence why a reed switching is currently being used. The only plausible solution I have come up with is using a reed switch in conjunction with something else where the reed switch turns on when close and the digital logic does the fine triggering. This seems like...
I am working on a product that is currently using a normally open normally closed [edited] reed switch that when a magnetic field is present turns on off [edited] a small LED. I was told other types of sensors like a hall effect sensor was looked into but the longest battery life that could be...
There was no spec other than "3/4 hard bronze" and there is no asking because the last guy is no longer working the project. Now its my responsibility to get this right so I want to make an informed decision.
I am looking for some recommendations for an electrical contact material.
I am basically picking a design change from prototype to production where someone else left off. I am re-designing a small sheet metal part that needs to also function as a spring to keep electrical contact with a watch...
