Anyone have a favorite surface mount power module?
Requirements:
-SMD
-No other components required for functionality (no resistors, external caps, filters, etc)
-5v, 500-900mA output
-12v input

Reprinting a lampshade I designed ~8 years ago. This time I printed both pieces in PETG with a 0.8mm nozzle. The first time, the clear was PLA and 0.4mm. The green PETG was still wet despite drying it, so I will need to reprint it.

An interesting fact is that both the filaments used were either originally intended to be used for this print, or were actually used in the print. I still had the rolls all these years later. The clear is almost gone, but I still have quite a bit of the green left.

@azonenberg I think that it was you that had come to a conclusion a while back that relatively cheap o-scope probes had a reasonably high bandwidth ~350-500MHz if I remember, but I cannot find the post. Was this you that had been playing with this and had come to this conclusion?

What can you do for ~$3 in filament? Custom print a shelf to hold your NAS, Router, and Doorbell Base Station.

Over Christmas break, I was able to clean up all of our wireless networking space such that it is a much cleaner installation and in a better location for speed and space utilization.

Am I the only one that uses drawing to maintain focus during classes or talks? I find it helps me to focus on what is being said while being able to ignore other outside distractions. This was my latest sketch of my Santa hat and an ornament on a wood floor.

Continuing with my concept development for an RC 1:72 BMT Defense SSGT submarine.

I have found a clean path for wiring as well as making the fins and propulsor shroud separable. The only compromise is using externally visible fasteners for the shroud.

No one yet has commented on my error in units labeling. One of my college professors would have marked the problem 50% off for that error. 🙂

Today's efforts. BMT Defense SSGT concept had a rotor between structural components. Challenging for a 1:72 model!

Needs to be:
-Structural
-Separable for assy and maintenance
-Pass wires for control
-Water tight

Not a trivial task.

Had fun over the last few days laying out a hull plane installation for an RC model of the BMT SSGT concept from a while back. I have three different models that will all need an installation like this. I find PowerPoint is a great tool for quick layout.

Sometimes it is the small things. I was able to design cup and handheld scanner holders for forklifts for some friends. Here is the latest batch for them. About 18hr and 750g of ABS for two sets.
