Project Name<\/strong><\/h2>\n\n\n\n

Receiver Box \/ Start Logger<\/p>\n\n\n\n

Customer needs<\/strong><\/h2>\n\n\n\n

Our customer needed an enclosure for a Raspberry Pi<\/a> 3B+ with a Witty Pi 3 hat and an Adafruit PiTFT stacked on top. Furthermore, he needed two USB ports and a Micro USB power port to be accessible from the outside, as well as the PiTFT touchscreen and 4 hardware buttons. In addition to the Pi, the two hats, and the two other components to go inside there needed to be two holes for banana plug connectors that came with specifications, which will connect to a small custom circuit board (with Gerber files), as well as an Arducam CSI-HDMI extender where the female HDMI port is accessible from the outside and the CSI cable is connected to the RPi camera connector. <\/p>\n\n\n\n

Quantity needs is for 1 prototype, but once the prototype is approved, anticipated volume of 100 in first 6 months<\/p>\n\n\n\n

The customer had some rough designs for all of these. The original design consisted of 2 shells screwed together. This design could be a good fit for our process, but not really cost effective and would require a some unnecessary workmanship. here is below the first design idea from our customer:<\/p>\n\n\n\n

Since the enclosure will be used in a very wet environment, we first thought to design the enclosure watertight but our customer has other requirements: The receiver box does not need to be watertight, but since it will be sitting by a swimming pool, it should be at least splashproof and rainproof, if possible. I’d also like to have the ability to mount this to a pole, so a 1\/4″ 20 threaded hole would be good so I can mount it if needed. Instead of a Witty Pi 3 board, I decided to go with an RPi UPS hat (<\/em>https:\/\/www.pishop.us\/product\/raspberry-pi-ups-hat\/<\/a>) instead, with the Adafruit PiTFT (<\/em>https:\/\/www.adafruit.com\/product\/2423<\/a>) stacked on top. The battery intended to use is this one: <\/em>https:\/\/www.batteryspace.com\/li-ion-18650-battery-3-6v-13-4ah-48-24wh-7a-rate-4s-s-ncr18650b.aspx<\/a>. The dimensions are 2.9″ (74mm) x 2.66″ (68mm) x 0.8″ (21mm). UC-392(B0091) v2 is the CSI-HDMI board, and I believe the PCB1 board is the signal conditioner. The two screws from the banana plug connectors go through the holes on that board. <\/em><\/p>\n<\/div><\/div>\n\n\n\n

An electrical engineer had also taken a look at creating a hat for the RPi that combines the LCD, the UPS hat, the signal conditioner as well as the CSI-HDMI board. The goal is to be able to revise the enclosure to simplify it without having to pay another setup fee.<\/p>\n\n\n\n

As for color and logo \u2013 I would like the plastic to be white, and the logo either printed on it in blue or engraved.<\/p>\n\n\n\n

2 circuits boards were ordered and sent our way:<\/p>\n\n\n\n
