After the country made vaccines illegal vaccine related death declined. In fact if you compare all countries where vaccines are illegal you will find vaccine related death is almost non existent. But in other countries where vaccines are legal vaccine related death is in the hundreds every year. I think this clearly shows why vaccines kill and should be made illegal.

This is what people who are anti-gun sound like. Do they even realize how absurd and how much lack of understanding they have when it comes to interpreting data and statistics?

So far on #QOTO we have brought the following services up, I want to know what you want to see next. All of these services are free and open to the public for open-source and collaborative non-commercial ventures.

Here is what we have up so far:

Modified #mastodon server - https://qoto.org

#NextCloud server - https://cloud.qoto.org

GitLab server - https://git.qoto.org

Servers we intend to bring up:

#Pixelfed

#FunkWhale

#PeerTube

#Discourse

#Halcyon

Let me know which of the above you'd like to see next. Also if you have a suggestion of a service we didnt list let me know and we might just host it for you if it would be useful for others.

Big things happening at #QOTO I wanted to update everyone on.

So as most of you know I had a year long back injury that put a lot of QOTO plans on hold. But I've been healed and working on bringing much of that vision to reality.

As of a few weeks ago a few close friends and fellow engineers wanted to join the team. I am currently sitting with 3 other new engineers and we are working on bringing up several instances including peertube, nextcloud, gitlab, discourse, and of course a newer version of QOTO. A full collaboration suite for others in STEM and the open-source community. All for free to its users.

This launch will coincide with several of my other projects many of you follow including protowaffle, ROES, Graphactor, Aparapi, Ferma and many others. We will host all the source on QOTO as well as make it the source for future software announcements related to those products.

Stay tuned for me.

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.

My favorite alloy is copper-gold alloy, here is why:

Copper is dissolved easily by acid where gold i not. Therefore if you rub any such alloy with acid you can eat away the copper leaving just the gold. This creates a similar effect as gold plating where a thin layer of pure gold is on the outside and the whole object looks like pure gold.

Of course gold is soft so even though the whole alloyed object is pretty strong thanks to the copper the thin outer layer is soft and wears away over time easily. When it goes from gold back to a rose-gold copper color just rub it down with a little more acid and it turns gold again.

Its much cheaper than pure gold but looks just as nice and is easily cleaned up. Its really win win in many ways.

Interesting note, the romans used to use this for their armor. Since they would clean it off with acetic acid from vinegar it looks like pure gold and thus was impressive on the battlefield to see. The gol shine would wear off fast from battle but was easily restored in the next cleaning.

Love this Gal's solar weather reports each week. Since I do a lot of Radio propagation stuff I really need to remain up to date.

Still one of my favorite #Astrophotography shots I ever took. It shows the core details of The Great Nebula in Orion. You can even see the 4 separate stars in the trapezium.

Attached are some older pictures of blackholes that predate the one released today, they are real, not simulations. Enjoy.

Just a reminder. Today's "first-ever" picture of a blackhole is not the first-ever. We have countless pictures of blackholes. This is just the first time we have been able to resolve the event horizon such that it takes up more than a single pixel. But like with all blackholes the blackhole itself is invisible and all you can see is the gravitational lensing around it. Something we have had for decades now.

It isnt the first ever photo of a blackhole, it is just the highest resolution of a blackhole we have.

Now that I finally got my Electrical Engineering workbench in place I had some time to work on coding up a e-ink display. I finally got it successfully displaying images. This display is 7.5 inches and can do red black and white.

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.

The first draft of the PCB protoboard I designed arrived. It is more beautiful than I could have imagined.

There is a sort of beauty in the order and chaos of a prototype design.

Just finished soldering together this frequency counter frontend.

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: http://dirtypcbs.com/store/designer/details/freemo/6230/smt-smd-prototyping-board-tssop-20-sop-20-sot-23-6

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.
