What Are You Building Today

...... For instance Q30,31 with 2sc3324, a sot23 smd part. ......

Warning!!! I’ve tested sot 23 even a 500V/0.5W piece. Three times it started OK, but after some time (several power ON/OFF and hours) without a warning one of Q30/31 has popped and corresponding resistor totally destroyed. Furthermore two ksc2690 (k216 eq.), one fjpf2145 (c3675) blown and damages to PSU. 

If you don’t know what you are doing (I obviously haven’t a clue) don’t change Q30/31. Let them be 2sc3675 (or fjpf2145 - I used it for more then six years now).

So I built I fire today...

This will eventually be a golden reference bias supply / doubler (because over-kill has no limits).

My probe apparently touched something it shouldn’t have. 

Quite the spectacular fireworks. My heart is still racing :)

Poubelle! 😁

One of the first words I learned when I worked in France.  Thanks for the pic.  Words couldn't have done it justice.

Attacking crowded smd boards with test probes are indeed risky business. My heart rate increases when I just think of it and sometimes my hands shake so it’s not possible…

Remarkably, most of the components survived. The current regulator, U1, was vaporized along with the set resistors. The main fire was from the bottom through hole resistor. 

Next step, Poubelle!

After that, I’m putting in a more robust current regulator.

Trying to make sure the next fire is bigger? :nate:

I was hoping for something quite the opposite, but one never knows :)

Made some simple clamps for the Shapeoko out of some scrap red oak. Don't have a finished picture because I don't have a flush-trim router bit to cut off the tabs. Still learning feeds and speeds so the finish is also questionable.

You inspired me to get off my ass and work on my first real mod for the Traeger, a magnetic cutting board to mount to the top of the pellet hopper.  I used the Shapeoko to machine a pocket into the back side of the cutting board as well as to make the recesses for the magnets.  Then used the laser engraver to etch Traeger's logo into the top.

I'll probably make a fancier version at some point but this will do for now.

slow n low...

Traeger's are a very convenient way to enjoy BBQ.  Nicely done!

Delivered this cutting board to my sister who is a lifelong quilter. *snip*E33BFB93-789D-474F-A2D2-335C9038556E.thumb.jpeg.ff793107b12d03943cf1d4611b656414.jpeg

Love the Traeger cutting board Nate! The magnets are a genius touch.

Love the cutting boards Al and Nate!

Nate:  I got this front folding shelf for my Traeger and love it.  Don’t know why it doesn’t come with the grill.

Shelly,

I'm planning something similar, just likely out of wood to accent the grill. If I get the manufacturing time down I'll make you a cutting board for your Traeger. 

Al,

That cutting board is gorgeous, well done!

That would be awesome (but of course not necessary)!

Since when is necessary a measuring stick around here? I'll shoot you a message with the dimensions that I need and we can go from there.
