  • 3D-printed 4-in-3 HDD bay

  • Feit SEC3000/CAM “bricked”

    Recently had to repair a bricked Fiet security camera. If too long of a WPA password is used it will cause a buffer overflow and the camera will crash which results in an endless boot-loop. There doesn’t appear to be a way to recover from this condition without getting serial access or access to the…

  • Adding a serial header to the Wyzecam V2

    I have been meaning to try the open-source Intergenic bootloader for years and only just got around to it. This bootloader allows 1080p mode when using Dafang-Hacks. When messing with the bootloader it’s a good idea to have the serial connection ready for debugging or recovery so I added a header that is easy to…

  • QEMU/KVM GPU Passthrough

    Was getting BSOD trying to pass through a 280X to Windows guest. Using an added PCIe root seems to fix it. Using the i440fx machine in QEMU also seems to fix the BSOD. I need to benchmark that against the PCIe with Q35. Standard options for the various modes using Q35 QEMU machine: BIOS Default:…

  • LeCroy Oscilloscope Memory Cards

    This article is related to so-called “memory cards” (MC01) or SRAM cards. Mass storage cards (HD01) generally Just Work if your scope supports them. I want to attempt to solidify information surrounding the use of memory cards (MC01 SRAM) in older LeCroy oscilloscopes such as the LC series, DDA series, 93xx series, and 94xx series.…

  • 3D Printed Motorcycle Gas Cap

    I lost my fuel cap during a night ride so I designed and 3D printed a new one. Designed in OpenSCAD with the threads.scad library by Dan Kirshner. Printed in PLA+. I wasn’t sure if the PLA would hold up against gasoline but so far, so good. My printed version is a little different design…

  • 3D Printed Zipper

    My motorcycle jacket is well past its end of life but I keep it on support. The original metal zipper slider (aka car) started bending internally until finally it wouldn’t work any more. I replaced it with a 3D printed version. Modeled in FreeCAD. Printed in PLA+. I planned to print in something else but…
