Seeking Your Feedback on Upcoming Experimenting Challenge -- Waterproofing Electronics

rscasny

I am preparing to launch in October an Experimenting Challenge focusing on waterproofing electronics, featuring waterproof connectors and a customized watertight enclosure.

I wanted to tell you about it. Give you some facts, and let you see what I have looked at thus far.

I also am seeking your input as a sort of wishlist. That is, What would you like (or should be) added to the challenge's kit in terms of electronics, single board computers, accessories, etc. Now's the time to provide me your input so I can determine my budget for the program. Of course, there will be some great prizes as well. (BTW, you can also offer ideas for prizes: grand, runner-up, third prize.)

Here's what I have:

Waterproof Connectors

The IP ratings of these connectors vary:

  • IPX4 – Protects from splashing water, no matter the direction
  • IPX8 – Protects when immersed in water over 3 feet
  • IP67 - "complete protection against dust over extended time" and "protected against short periods of immersion in water while under pressure between 15cm and 1m.

Watertight Enclosure

  • Enclosure Material: Polycarbonate
  • IP Rating: IP68 - total protection against solid ingress and total protection against water ingress, up to and including complete submersion below one meter and for more than 30 minutes.
  • NEMA Rating: NEMA 4, 4X, 6, 6P, 12, 13
  • External Height - Imperial: 2.36"
  • External Width - Imperial: 5.51"
  • External Depth - Imperial: 5.51"
  • Note: I chose the size; however, feel free to suggest another size.

Customizing Watertight Enclosure

I am having the enclosure customized. The manufacturer will cut the holes for the connectors. So, it would be helpful to know what connectors you would like to use:

The Wishlist: Other parts to include in the challenge kit

Obviously, we want to mount a PCB in the enclosure. Cables and mounting hardware might also be needed. What is mounted in the enclosure can vary; that is, what is mounted within it can vary from participant, since the focus is testing/experimenting with the viability of these waterproof/tight devices. So, what to add to the kit, is based on your need, interest and/or creativity. But all participants will receive the same connectors and enclosure.

Your thoughts?

The community always offered interesting ideas that often change what we offer in the kit or how we frame the challenge. So, feel free to post a comment with your thoughts.

Thanks.

  • I recommend providing kit with all posible connectors because user can decide which will use and which will not use. For example if only USB will be provided than contestant requiring DSUB will not be satisfied. In opposition when all connectors are included then user will use DSUB and just do not use USB if he do not need it.

    For reward I recommend using concept of choice from two options like it was in older design challenges like Experimenting with Thermal Switches. In all recent contest reward is some kind of iPad which is nice but I already won one ipad and for me winning second iPad makes this competitions less attractive. Choice from consumer grade electronics (for example iPad, laptop, gaming console, VR headset, ...) and electronics design helpful device (for example oscillscope, arbitrary generator, advanced soldering station, ...) is good compromis I think. Budget usualy allows providing even very advanced rewards.

    We can go with test equipment. We have for some programs in the past. In the last year, I've sort of felt people like the consumer electronics, but we can change up. Thanks for mentioning.
