It does make one wonder why, when the police lay out the range of firearms that a bunch of Gravy Seal terrorists bring to the beginning of their war against the government, it is never a table of Smith and Wesson oak stocked hunting rifles. It's because they watch too many movies made in the US and play too many shoot-em-up video games and want to play soldier. THAT is the reason that this type of firearm is being banned. It's not because of how they look but because of the type of people who want to own them and why they want to own them. I have absolutely zero concern that the government is ever going to come for my guns because I didn't buy them to feed into my part of the collective murder fantasies of the anti-government nutjobs.

I have always found this to be a funny argument.

"You have two guns that are of the same caliber, fire the same cartridge, have the same rate of fire, and the same killing power but one is non-restricted few one is prohibited. I should be able to own the prohibited one."

Why? You can get the exact same function from the non-restricted one. The only difference between the two is how they look.

I, a 40 year legal gun owner, believe that it is because of how people think the restricted firearm makes them look and how they think it makes other people feel about them.

How about this. This is an idea that I've proposed to people many times. You can keep those firearms but every part of the firearm, everything that goes into or onto the firearm, everything associated with the firearm has to be hot pink. Possessing a firearm or anything associated with a firearm that is supposed to be hot pink but isn't means you instantly and permanently lose the privilege of owning forearms in Canada. Selling or repairing any firearm or anything associated with a firearm that is supposed to be hot pink means you instantly and permanently lose you license to sell or repair firearms in Canada. Allowing any firearm or anything associated with a firearm that is supposed to be hot pink but isn't onto your range means that you instantly and permanently lose you licence to operate a range in Canada.

The only difference between the firearm now and in my proposal is the colour.

I don't give the first fuck what color the gun is that I'm shooting at the range. I'm prefectly happy to shoot a hot pink or neon green or day glow orange gun.

The First Nations have heard a lot of empty promises from a lot of vote grubbing politicians. They want plans, not promises, and Poilievre has no plans. His grievance politics and obviously impossible promises play well to the gullible mouth breather crowd but people with actual grievances see right through him.

I'm still touching grass. I'm touching so much grass that it clogged up my trimmer.

My son, whose report card I just got and found out that he made honour role, just came out to find me to show me a beautiful French rolling pin he made on the lathe. I just had to add string to my trimmer so I thought I would check in on how your rage is going. I see it's still going strong.

I hope that one day you can find real happiness like I have.

I will sleep very well after I have a shower to wash off all the grass I've been touching all day.

I really am sorry that you're so angry and miserable.

[–] MapleEngineer 1 points 1 year ago (4 children)

You're projecting. I've been checking in with you between whipper snipping around my wife's gardens. I've spent the entire day outside in the sun under a clear blue sky and now I'm watching YouTube videos and having a cold drink.

You really are a sad, angry, pathetic person. I hope you eventually find happiness.

[–] MapleEngineer 0 points 1 year ago (6 children)

That's what it takes to make you happy? Thinking that you've hurt someone? That is a truly sad existance.

I hope you some day find a way to be happy.

[–] MapleEngineer 0 points 1 year ago (8 children)

That's good. I hope you have a good day.

[–] MapleEngineer 0 points 1 year ago (10 children)

I hope you find a way to be happy.

[–] MapleEngineer 0 points 1 year ago (12 children)

I'm sorry that you're so angry. I really feel sorry for you. I wish you were happy.

[–] MapleEngineer 0 points 1 year ago* (last edited 1 year ago) (14 children)

So much anger. It must really eat you up inside. I'm sorry that you're like this. It's got to be very stressful.

What was I thinking?!?

In this video I take a crack at soldering a QFP-32 with the inexpensive Walmart soldering iron and the mystery Chinese solder.

 

Will it solder?

In this video I used the $15.88 Walmart soldering iron and the unknown Chinese solder that came with it to solder a DS1307 real time clock in a SOIC-8 package.

 

Will it solder?

In this video I used the $15.88 Walmart soldering iron and the unknown Chinese solder that came with it to solder 2.54 mm header strips onto a small adapter board.

 

In this video I go back to the beginning of my more than 45 years of experience soldering and buy a $15.88 Chinese soldering iron from my local Walmart store and compare it to a Weller PES51 pencil iron connected to my WESD51 soldering station and a Hakko FM-2027 connected to my FM-203.

I have said that you can use the cheapest soldering iron to solder SMD devices like SOIC-8s and QFP-32s. In subsequent videos I will attempt to solder pin headers, a DS1307 real time clock in a SOIC-8 package and a LGT8F328P MCU in a QFP-32 package.

The goal of these videos is to make clear that even beginners can solder modern SMD devices using basic soldering equipment that is readily available locally to most people.

The other day I went out in the morning, drained and rinsed the ducks pool, and put the hose in it to fill.

That evening around dinner time I went, "FUCK!" and ran down to find three very happy ducks and turn off the hose.

So I added this automatic filler. Now when I rinse the pool it will fill to a couple of inches from the top and stop.

One of our Bronze Orlopp toms reaching through the fence to steal the duck's feed. They really aren't starving. They have a 35 lb feeder full of turkey grower pellets they can access 24 hours a day. It just tastes better if you steal it from your neighbor.

 

When I first started using AVRs I bought a couple of UNOs. I needed something smaller that I could use inside controllers for my machines. I moved to the ProMini and it served me well for two or three years. I got a couple of Nanos in Hacker Boxes and really liked them. I like the built in voltage regulators, the USB port, and the ICP port. I used Nanos for a couple of years then needed something bigger. Now I'm using the ATMEGA2560 Pro Mini. It's got enough IO to run my entire room.

I've recently switched from Bascom AVR to Great Cow Basic. I'm thinking that I may need to mode to a PIC based MCU.

Does anyone have a favorite PIC based MCU board similar to the ATMEGA2560 Pro Mini?

This little power supply board plugs into a ProMini shield stack or the ProMini Backplane boards that I designed. It's basic but it has a couple of nice features.

In this top view:

A - Power inlet

B - Screw terminals for offboard switch

C - Jumper across switch screw terminals

D - Reverse current protection diode

E - 5V regulator

F - 3.3V regulator

G - 3.3V/5V on Vcc rail jumper

The switch screw terminals let me use an external switch to turn the power supply on and off. If I'm not using an external switch I can use the adjacent jumper to tie the power supply on or I can put the jumper on and take it off to turn the power supply on and off.

The power supply puts the supply voltage from the power connector onto the Vin rail on the ProMini Backplane board. There is a jumper on the next slot over to allow me to take Vin off that socket so that I can put the ProMini in there and not have it powered all the time.

You can see two round pads between the white power inlet connector and the green screw terminals. This is an optional 2-pin header that sends regulated 3.3V and 5V from the power supply board down to the ProMini Backplane board to supply screw terminals to allow me to power offboard sensors or other devices easily.

You can clearly see the extra 2-pin connector in this bottom shot.

This board was designed in DS PCB before I switched to Pulsonix. I had them made by All PCB and assembled them by hand. This was a fun little project and I use these little boards quite often.

Here it is in action. The PSU board and a ProMini installed on the left ProMini Backplane board. You can see the 5V, GND, and 3V3 screw terminals to supply offboard power. I've also got two Backplane boards daisy chained together. You can also just see the 6-pin ICP port to the left of the screw terminals.

 

I needed some LEDs so that I could track what my data lines were doing. I started with a bunch of LEDs and resistors on a breadboard.

From there I made up a small block of SMD LEDs and resistors on a piece of proto board.

Then I moved to an actual prototype on a dedicated protoboard.

Finally, I produced the finished product. BLINKY LIGHTS!

The friend who I work with can design a board entirely in software, we use Pulsonix, without every making a prototype, send it for manufacture, and get working boards back. Even when I build multiple prototypes I often end up with boards that need FECs to make them work.

When I started soldering everything was big and had leads that went through holes in the board. You inserted the leads, bent them over to hold the component, flipped the board over, soldered everything, and trimmed off the excess leads.

Now I'm soldering things down to 0402 SMDs (1/4 the size of the smallest component in the picture) using a needle point soldering tip and a microscope.

A pair of 2N2222 transistors, one SOT23 and one TO-92.

 

This is the setup I used to calibrate the vacuum sensor. The vacuum line connects on the right. The right T is the vacuum sensor. The left T is a vacuum gauge. The ball valve allows me to easily release the vacuum.

I use the vacuum transducers to monitor the vacuum level on the pump side and the collection (tree) side of the vacuum releaser.

 

This is the breadboard prototype of the first iteration of the industrial controller that I use to make maple syrup and that I call the SapMaster.

The Arduino Nano version ended up in a PVC project box from Turkey.

The Arduino boards is on the left in this photo.
