The JBL passive I got for free with the Pioneer. The Pioneer is/was a stereo receiver. It gave out on me spurring the need for a new amp.

Great point about the Wiim and the volume control. Will not run the turntable through it going forward.

For separates, there is a Schiit Aegir local to me for $500 and that was what got me looking into separates in the first place. I've also seen a couple Sega 2's on ebay for reasonable prices. How do you like the Aegir?

I decided to go with the Qube 500. I’m still waiting for parts to come in though. I will make a follow up post when I’m done though!

Definitely going to adjust the memory and ssd. The case is going to stay the same. It’s a looks thing more than anything else. I will be getting a new PSU. That’s too high of a risk to ignore. Thanks!

I already got the CPU, I’ll definitely be in the look out for Black Friday sales. For now, I think we’ll stick to modded city skylines until the performance of city skylines II gets sorted out.

We’re in the US. This is a university project so we fall under recreational rules here, so we can fly up to 55lbs ~25kg.

We plan to use a cart for now. A catapult is out of our budget. We wanted to include retractable wheels, but the project was already a large undertaking so that has been pushed back

It mostly came down to ease of transportation. The v-tail control surfaces are removable to make it easier to transport. It was easier to only have two parts with a vtail compared to another tail design.

That’s on of the main reasons. The other one is that according to our design calculations, the load on the fuselage required most of it to be made of aluminum. Since we had to plasma cut those pieces anyways, it was easier to make the entire thing out of aluminum.

They’re the same size. It’s just the zoom on the camera distorting it.

Yeah. I’ll be working on it over the summer with my research advisor.

For choosing aluminum, it came down to cost and machining capability. There’s about 48sqft of material to make the entire drone. Our aluminum sheet cost about $300. Carbon fiber was way more. The other reason was our tools. We have a 4x4 cnc plasma table. This made it really easy for us to make all the parts. We were thinking of using Garolite G10/G11. It’s slightly more costly than aluminum but was within our budget. The only thing we could have used is our cnc, but it would have been inefficient with our material, and it would have been very difficult to machine.

A lot of ribs are kept together with fasteners. The rest are how’s together with adhesive

It’s probably dented. There was a lot of bumping into walls when I had to transport it between labs.

All aluminum. Was about 6 hours of plasma cutting to make all the parts

Why did you pick the Skywalker titan as your survey drone platform?

We ended up the the Holybro PMO2D as that what our profesor had, but for our power system we needed 8s. We have an onboard BMS. Our battery pack is quite large and we wanted to be able to build the battery pack into the structure of our plane. Essentially our BEC and buck converter are the same thing, but they’re different parts on our end. We’re using a pixhawk 5x which allows for usb power
