Hahaha I think you both are borrowing pis from ME, not the lab 
An interesting thing we noticed is because you ARENT printing your TPU in the tropics , your prints are a lot smoother , but because we tuned ours for the crappy printing we had, your ties tend to be looser than what we calibrated for
Laser Cutting Parts
I am using a Trotec Speedy 400 CO2 laser cutter for my acrylic parts. I ordered 3mm PET acrylic to cut my parts but I quickly found that out cutter left a yellowish hue on the edges of the parts and slightly melted the material. I am sure I could dial in the material settings for the laser cutter but I opted to cut the rest of the parts with scrap acrylic we had around our lab.
I used Adobe Illustrator to edit the .dxf files. I noticed that target.dxf has a random scribble on layer three of the file. Seems like a mistake so I remove it before editing the file.
Another thing I noted when using the Adobe Illustrator was that when I imported the target_material.dxf and plexi_front.dxf files, was that the design goes off the workspace. When I sent the files to the laser cutter, I didnt initially notice that it cuts off part of the design. So I ended up with 80% of a felt target. I ended up copying the designs to a larger workspace to fix this problem.
Assembly Update
My Mothbox is complete!
The overall process took about 5-6 days of work to build. It would have been completed sooner, but I was only worked on it a few hours each day. Most of the time that went into the assembly was the laser cutting and 3D printing. the actual assembly of the components could be done in an evening. I recon someone who had all of there materials on hand and proficient with all the necessary equipment could fabricate a Mothbox Pro in a day or two.
A few notes on the final assembly steps:
I opted to use heat inserts for attaching my plexi front to the outer shell like I did with the PCB. While screwing the plexi front on, I managed to sheer one of the heat inserts out from the out shell and had to take the plexi front off to reevaluate. I tried widening the screw hole a tad and inserting a M3 heat insert but that took sheered out. I ended up hot gluing the insert in and called it good enough.
I would say that if you are to use heat inserts rather than screws, defiantly look at the outer shell STL file and confirm that your heat inserts are compatible with the screw hole diameter. I would have made the screw holes slightly smaller.
I had to use a glue stick to attach my felt to the target because I unexpectedly ran out of spray adhesive.
I also had to go back and cut out another 2 arms. The photo of Mothbox Pro parts shows 2 arms (after looking back at the photo, they might be stacked on each other) but it isn’t until I got to the External Parts - Arms step where is mentions that each arm consists of 2 arm pieces.
I cleaned up the zip ties that were covering a few of the LEDs on the PCB.
I am also a HUGE fan of the TPU reusable zip ties.
I tested out both the LEDs and Mothbeam and they seem to have no issues!

Setting the Time
I am looking to deploy my mothbox in my backyard tonight to see what critters I attract.
I have everything set up to run over night but the one issue I am running into is trying to set the time “using the internet”. I set up my iphone to display a hotspot showing DINALAB with the password iloveyardpigs, as per the instructions. I was in the DEBUG mode and had changed my timezone to US/Pacific yet I still couldnt get the mothbox to connect/ display the correct time.
I ended up setting the time manually so I could get some photos tonight.
Curious if anyone knows if I am setting something up wrong or forgetting something obvious. I dont have the RTC battery connected yet, should be coming in this week. I don’t think this is the issue but it could be!

I also struggled to get my Mothbox to sync the time initially. If I remember correctly my issue was that I didn’t have the Mothbox set to ACTIVE mode - even DEBUG needs ACTIVE to be enabled first. Otherwise it turns off (red LED on Pi) before it gets a chance to connect to the WiFi hotspot. The other thing to check is to make sure you have the battery fully charged before you start!

Thanks garrit! I was able to get it to connect. I tried again with a fully charged battery and made sure the display showed “DEBUG” mode. I am pretty sure when I was trying to set it in the past, the battery wasn’t fully charged. Thanks for the help!

First Usage
I went into a park behind my house for my mothbox’s maiden voyage.
I added another mothbeam for a total of 2. Both of them are configured to be at “minimal power” and I was surprised to see them at different intensities. I plan on redeploying it tonight with them both set to the “standard bright” mode.
I had an issue with the internal pi clock since I have been setting the time manually and still havent received my RTC battery. I ended up taking photos from 12am to 10am instead of the 7pm to 5am schedule I intended. Since then, I have been able to set the time using the internet, and am making sure not to turn the battery off until I collect the box in the morning to make sure the clock does not shift.
Unfortunate, due to crazy winds last night, moth activity was quite minimal. I managed to capture a mosquito though! very exciting stuff.
Going to deploy again tonight. Its going to be equally as windy and a little rainy so we shall see.
Congratulations! You are rocking it! When i get more time I will look through all your awesome documentation! But wanted to say, way to go!
Also 2 things
1- while you are waiting you can try to use the post processing workflow to go through your data and see finds that mosquito for you automatically!
2 - you can toss some of your original images into this folder and we will add it to our training data set that we are going to make the next version of the machine learning detection model from.
Just toss in some of your images that have bugs on them into this folder and we will handle the rest
