It looks like wavy-gravy power traces going from the heat sinks to the front. What the hell

Power traces or nice smooth differential lines?

Got to love the high speed acquisition porn!

Some precision gear in pristine condition and for peanuts (HP 6113A).

It is a bit off, but I really can't complain... It does not have any calibration sticker, and its date code is 27th week of 1981.

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

I don't know! I never seen anything like that on a modern high density multi-layer board.  They look like the old hand drawn traces style.
You are probably right, they are signal lines as there so many of them. Strange.

I did a T shape engraving on a Toshiba flash chip with my new Cubiio toy laser.
The left is a failed attempt with bad focus, and the right is a perfect T with crispy but slightly burned edge.



The built-in rasterizer was way worse and it will guarantee to mess up some corners.
The T shape shown here is based on my own rasterizer using only G01 X and G01 Y code.
The firmware implementation of G02/G03/G01 X Y motion is flawed and is guaranteed not to work precisely with small feature sizes.

You shouldn’t burn an F word in Chinese, it’s very rude.  :-DD

Not the best photo... Should I buy a 335D and calibrate it myself? Need to order all the aluminum electrolytics and replace them but mostly in good shape and stable.

New keyboard and mouse for the shack. Needed a few more buttons to make CAD work easier and the old keyboard has seen much better days.

How did you even get it for 2k? The list price is over 7k. Thats some serious negotiation.

Lazy bugga for not rolling your own timer you could have got the parts for maybe $3-4 :-DD I have memories of 555's alone being nearly $2 each as a kid.

I just got a SDS1104X-E to go with my bench power supply I purchased last week.

I have BS degrees in CS and EE both in 1996. Since this time I have worked for the same medical imaging research team primarily as a programmer. Now at 47 I am trying to get back into electronics projects.

a lot of second-hand Fonera mini routers. One has been overclocked, so it needs more heatsinks and a cooling fan :D

Picked up a Fluke 189 for $123 shipped, thanks to an ebay promo, an auction with a weird ending time, and a little luck.

A silly expensive battery for a SMIQ03.



I'm OK with manufacturers using expensive, non-standard (ie. I don't have a box full of 'm) backup batteries but then I *demand* that they last forever and a day. Not shorter than a PC with a CR2032.

Why dont you just put in a 1/2 AA holder and then use the normal 1/2 AA lithium batteries?

I did this retro fit to my old Mac SE which had one soldered in.

eg https://store.retrofixes.com/products/macintosh-se-pram-holder

The impossible often has a kind of integrity which the merely improbable lacks.
