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…

Small Plastic Shelf Bracket
During moving some furniture we lost a bunch of these tiny brackets that insert into the sides of shelf cases. 3D print to the rescue. Modeled in FreeCAD. Printed in PLA+.

Outside Light Mounting Spike
Another 3D print I designed in FreeCAD and printed for someone else. These things break all the time because they’re pushed in to the ground and are fairly expensive to replace so 3D printing is a good option. Printed in PETG.

Sink Drain Stopper
3D printers are an endless source of usefulness. My ancient bathroom sink drain plug lifting mechanism broke such that it was always stopping the drain. I couldn’t leave the plug out because if you drop something in the sink, down the drain it goes. So I made a plastic version sized slightly different than the…

Honda motorcycle OBD/k-line interface gear indicator
I’m building a gear indicator and information display for my CBR500R. It uses an Arduino Pro Mini, Nokia 5110 display, and hooks in to the Honda diagnostic connector under the seat. Protocol is a custom OBD k-line format. Here is some useful information on the protocol used. The first version I created used 2N7000 MOSFET’s…

Motorcycle Stand
I used FreeCAD to model this simple motorcycle stand before building it. It’s made out of 2×4’s with glue and screws. I think it could easily hold a whole car up.

FemtoWii
This is a small 25mm by 30mm MultiWii board I started designing a while ago. I haven’t had much time to refine or test it. I did create a prototype board but that’s about it. The intent was to create a board small enough to be used on micro quads, helicopters, and planes. I’m providing…
