A Raspberry Pi Case to solve

Amazon delivered today Bomei Polyimide Tape https://www.amazon.ca/dp/B08Y8L2W6D?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 It is what Amazon search returns if you are looking for Kaptop tape, the productShabaz suggested.

I purchased 10mm width rools. My calipers measure 11mm on the width of the SD card had sitting on the bench.

Folded the tape to form a pull-tab on an SD card. The tape thickness measures .10mm on my caliper where my cellophane tape measure .07mm

I used some tape to make a few tabs and discovered folded lengths greater than 20mm, not including the portion attached to the card, is ideal for making a right angle fold so the card can be inserted with the Pi case flush against a surface.

I experimented with a shorter length and that only resulted in new swear words. I confess even with the longer length, the card catches the card holder bracket but it was still a struggle to insert. I need smaller finger to push the card all the way in through the case hole. The tape is a work around. Taking the case off the wall to replace a SD card is a pain.

Let hope power bumps that take out cards are in short supply.

Hi Sean,

There's some Linux hardening that can be done, to make it less likely to corrupt on power failure, however your org will probably need to hire a Linux expert to assist with this, if they wish to do it properly. It's a common thing to have Linux inside apparatus that may lose power, and it's a different skill-set compared to software developers creating desktop apps. Bearing in mind that it costs a lot of money to have someone manually pull out microSD cards whenever there is an issue, it may well become cheaper to make the Linux and app installation more resilient to reduce the need for manual intervention.

Another approach is to add hardware to be able to ride out intemittent power outages/brownouts. I don't know how often it occurs and for how long, since that may impact the possible solutions.

What are the Pi devices used for incidentally? What specific app is running (if it is not sensitive to share this detail). To be fair, it is technically misuse of Pi's, they were not intended to be used in corporate networks, is there much cost or energy saving in using them over other options?

The corrupt card is the first I have experienced since using the first version of Pi. I've screwed up SD card just unplugging the P.S. but never had it happen in a production environment.

The failure after the power bump was associated with network services on the pi. The Pi would not establish a network card. The Pi came up but no network. A light came on but no winks or blinks. A simple re-image and network restored. I did replaced the SD card for the re-image jsut to be safe.

I've been using Pi's for low cost monitoring Network UPS servers. I have some UPS deployed that are not associated with Windows computers. The Pi's monitor them, giving me some reporting.

The major production use in the company network was Pi 5's as pihole servers. That was just recent. One of these servers was taken out in the power bump. There is one redundancy and third a fail safe option so users don't lose DNS completely. It didn't come to the third option.

The Pi's share a UPS but this power outage/bump used up that backup and even drained all the emergency exits lights. I showed up at the failure with one bulb in one light working. Cellphone flashlight got me in and out of the building. Power was restored 5 hours later. 

Having to troubleshoot the card issue was an nuisance. Not being able to remove the card without taking the case of the wall, gave me reason to swear. I would gold, silver and bronze if swearing was an Olympic sport.  It took me less than 15 min to restore the downed pihole server once I got the card. In the grand scheme of things I shouldn't be concerned.

I'm proactive. If this happens again, I was looking at being prepared. If I continue to use Pi's then I need to anticipate the problem. A different case, I hoped was the fix. Not the case:) The tape works. The kaptop tape will work longer, I'm think since it is temperature resistant it won't give out when I need it.

Thank you for sharing your insight. I try to avoid creating problems. The network is for small company. I suspect if an IT company took over the management, my solutions would be replaced with enterprise alternatives and a larger cost to the business.

 colporteur , if a PI is so sensitive to power mishaps, maybe not the best choice to monitor UPS health?
