So I got the raw 3d MRI source files from the hospital. Then I got the software needed to view the MRI in 3d. It let me rotate, slice, and even colorize the images. So **I** generated these images from the raw MRI. It shows my kidney, heart, and skeleton from 4 different angles fully colorized. How cool is that!

I also included some of just the heart and kidneys on its own from the same scan.

An Advanced SWR meter I built about a month ago. It calculates phase shift so can compute a complex impedance and complex SWR, something most meters cant do. Schematics included.

@snder By the way this project forms a third company under cleverthis.com. This one you likely wont be getting involved in because its hardware and a relatively small project. But just wanted to show you part of what is under cleverthis

I've finished writing part 1 of "OcapPub: Towards networks of consent", which is to say the "Conceptual Overview" section gitlab.com/spritely/ocappub/bl

There's a lot there already, and we haven't even gotten to Part 2, the "How to Build It" section yet. I'll begin work on that tomorrow.

What's here already is more or less an explanation of *why* OcapPub is taking the particular direction it is taking, and why other approaches run into serious problems.

I passed out pretty hard last night with my notebook and pens still out on my bed. Rolled all over them last night :(

So I recently got a few thousand boards printed up for my protoboard design. Tested them on a few circuits and im amazed how well they work. I'm writing the datasheet now and we will begin selling on digikey, mouser, and many other big names soon.

In the meantime any EE people out there want a free board? We are going to hand out a few hundred for free to get people interested.

Here are some past posts I made about it for some background info. I've also attached an image of the final boards.

After several more hours of cleanup the Prototyping SMT board I've been working on is finally done. I attached both sides of the board below.

Here is a link if you want to order a few for yourself. If anyone is really interested I can even send a few out for free to try it out: dirtypcbs.com/store/designer/d

I havent decided yet if I want to make this open-source. I probably will.

It can act as a simple breakout board for either a single SSOP-20 or x2 SOT-23-6 chips. To use it as a normal breakout just use solder to bridge the 20 connectors on the right and left and sides of the board and it will be a normal breakout (which each pin on the chip going to one of the header pins directly).

Here is the full description.

However there is also a SMT grid on the front and back so you can solder a full circuit onto the chip and arbitrarily have any point in the circuit wired to the various pins. Which makes for very handle little modules you can solder up and reuse.

I also added two power rails for ground and VCC down the middle with vias to both sides of the board. I also added other connectors around the edge that add in vias and wires connections to the opposite side of the board. Should be very useful.

One other little hidden feature is the spacing. Most of the pads are the perfect size to fit most two terminal SMT components (x4 0603 components can solder onto a single pad). But because the pads down the middle are offset it is also very easy to solder on SOT-23 connectors that have 3 terminals. So you really can solder almost any sort of SMT components on here.

Next step will be to build a larger protoboard that can accept modules like this and similar to create more advanced circuits.

Attached are images of the top and back of the design.

An image showing how the protoboard I designed is laid out as well as a picture of the printed board and my Frequency Counter design soldered to it as an example. I also attached the schematic for reference.

Anyone know why I just got some random 300 some followers from weedis.life? They seem to be nonsense accounts of some kind. The notifications are very annoying. Anyone one else have this problem?

@Stoned2TheBone any idea what is going on with your instance?
