Need a handheld enclosure for 16x2 LCD

If you think bigger quantity, like in the millions, can this be ported to Bluetooth (or IRDA, or USB) and the 'handheld' item become a cellphone or old Palm device?

Bluetooth (or IRDA, or USB)

Then we'd have to write an app, and maintain it every time some new upgrade is released. Nice idea, but "No thanks". :)

I'm a big fan of IrDA, but a lot of phones don't support it. And again, that puts us back in a developer's seat, which I'd rather avoid. We already have RS-485 on the product. This is basically a tester for th e tech who has to install the system (to avoid requiring them to breakout a laptop and RS-485 adapter.) I know... old school, but it works.

Hammond Manufacturing makes a great assortment of both hand-held and desktop cases, both plastic and metal. Readily available at the major and minor suppliers...

A nice handheld case is this one:

Aurduino, etc. project cases:

Nawww... you want one that handles two 18650s.

At that qty 3d print the box to what ever specs and shape you need. Hammond boxes will probably run you north of $10 each.

He said ten a month, not ten each. These days $10 each sounds like it would be sure to be super cheaply built as well.

A solid, hobbed out box and seal. Keep the electronics and the battery safe and dry. Yeah... that's the ticket.

And I think china made 25 for us pretty quick turn and pretty cheap. I cannot remember the price. email on a different box. It was 5 years ago.

Unprotected 18650 batteries do not have an electronic circuit in the cell packaging. Because of this, there is always a danger of over heating, short circuiting, or over discharging. Unprotected batteries are also much lower in price.

I found these two on Pac-Tec.

I don't think either one of them is the correct size opening, but I can pro bably make it work? The volume isn't there to do a full-on build, but mayb e that's the answer? I'm still a bit shocked there isn't something out the re already, given how popular these little 16x2's are with the hobbyists.

Pactec has some nice enclosures. Bezels are hard to find, unlike 20-30 years ago when LED displays were common. They can be 3D printed, for small quantities. Here is an example with a 9V battery compartment:

I have a couple of their TR series.

I also have a couple of these:

No battery compartment, but they have a hole in the back to run wires into them. It shouldn't be too hard to use the two slotted mounting holes to retain a battery cover, and they are cheap, at around $2.50 each.

rectangular shape, it has an opening for a 1602 display and below that three moulded buttons. there are keyholes in the back for wall-mount. It looks like possilby intended for an electronic thermostat.

Very cheap but fails most of your other requirements.

IP42 seems ambitious on a device with a battery compartment and an RJ45, passing IP42 with a 1602 display would mean a window in front of the display or some sort of verandah.

Thanks, that's actually rather nice-looking. (for what it is.)

Plan-B might just be to get some graphic overlays from JRPANEL.COM and just cut a standard box to fit.

probably quicker than finding just what you want. Print in ABS & acetone smooth.
