Hi Gang all set to solder up the board intend on using the same order of assembly as V2 instructions. and that means starting with the capacitors. With the pDf that Lenny sent and the markings on the board I am comfortable as to location of components. I understand how tell the polarity of the each capacitor but getting the positive on the right track has me baffled. I checked the schematic and maybe I can follow the tracks to determine ground. seems a little risky. av888tor/gmail.com Mark Wyss
Hello! I'm new here and this is my first post. I just discovered this project and I'm very interested in the AOA and am looking at what it takes to construct one. I don't have much solder experience, but after looking at some youtube instructional videos, it doesn't look like it will take much practice to be able to do reasonable through-hole soldering. I have a background in software and shouldn't have much trouble with the software part. So I downloaded the hardware assembly instructions and looked through them. Looks very doable, but the title is "OnSpeed Generation 2.0v2 Assembly Procedure." The current version is Gen 2, V3, right? Is the V2 assembly document the same as the V3? Perhaps just an upgraded IC or two? If not, when will the V3 assembly document and BOM be available? I'm not really in a hurry, I'm just curious, and maybe a bit excited, and am interested in starting to acquire the parts. Sadly I'm not a candidate for beta tester. Though I have worked in software test and would love to help, I live kind of far from my RV-4. Like nine time zones. Long story, but I won't be useful to you other than to test the construction and bringup process. This is a very cool project and a big thanks to Vac and all the others who are making this happen! -jim
The board files found through this link : PCB fabricated by PcbWay.com (affordable and quick turnaround circuit boards) https://www.pcbway.com/project/shareproject/OnSpeed_Gen_2_v3_0.html shown on https://github.com/flyonspeed/OnSpeed-Gen2/tree/master/Hardware does not match the Eagle board file also found on github. The parts project on the same page does seem correct. Found out when my boards arrived. Should have compared the zipped up Gerbers against the Eagle files before ordering.
