There was some discussion in a previous post about the pulse dampers causing some pressure related problems when placed directly on the rail.

I added four high speed pressure sensors onto the inputs and outputs of the fuel rails, and I think that should enable me to see if such problems exist. I should be able to sample these sensors at 500hz (2ms), which might provide enough resolution to see oscillations. If needed I can swap in some faster sensors.

I must admit the intake manifold looks better than I thought it would.

With the footers poured, construction of the forms for the foundation wall are underway. Yes Neil A. Switzer, I have notified the NSA that the battleship is nearly ready. 😉

Mmmmmm.. Gold. Nice that the Injector Dynamics hats happen to be gold for these ID2000. That Paul Yaw thinks of everything. Radium pulse dampers as well.

I put up a second video about the Subaru build. 11 mins you will never get back! I will be doing videos of the entire build, install, and calibration, so if you are interested, subscribe as I won’t post them all here.

I have a reasonable number of meetings that involve people transmitting data at suboptimal baud rates. Doodling has always been a valuable way to provide some mental exercise and increase my retention of the important bits.

I have always tended towards doing designs during these idle times, and in particular I like designing microprocessors. I find that post-it notes are a good way to organize hierarchical design, and makes it easy to pick up a design months later. Sometimes I’ll do something novel like a single instruction design (‘mov’ obviously), something like a 128-bit VLIW, a yet another MIPS knock off, or in this case a very compact 8 bit design that can be implemented in a reasonable number of old school 74 series gates. Sometimes I’ll just write out stuff in VHDL, but doing old school Kmaps has its place.

It is really simple stuff, but I find it very relaxing and calming.

What do your doodle designs do?
