And designers who actually understand how to design useful and well-behaved products, web sites, etc. It really seems like things get crappier year after year. Or maybe my tolerance threshold simply gets lower with age. :-DD

And after a bit of lurking around, I found something worse.

The so called 10Gbps USB controller derives from an 8Gbps PCIe lane, and the same controller also has a 5Gbps port which was not clearly marked.

If you want to advertise on speed, make sure you note it that when you use this port, don't use xxx port, and they failed to do so.

That's why my test shows bandwidth rivaling on the two ports that were not rated the same speed -- supposedly they didn't come from the same controller -- wrong.

I really don't like the way Apple ecosystem treats people like babies. I would be very appreciating if they publish a topology map, i.e. which port comes from which controller, which has how much H2D bandwidth allocated in TBT3 controller.

I am glad that OWC published their 14 port dock controller chip information, and since OWC cloned TS3+ dock, I'm confident that they use the same topology. Thank you for not treating us like babies.

drescherjm they're not bad power supplies... just be very careful of the preset buttons!

if you're not using presets, go through ASAP and set them all to 0V.

I was working with someone the other month and they had a prototype rigged up with a bunch of these supplies... they reached down to turn the outputs off on the different supplies, and managed to hit the preset button next to it instead. The preset was set to full 30V and full 5A CC. The circuit it was wired to was designed for a maximum of about 6V.... not a happy accident.

Thanks a lot. I just got the supply and the defaults were 30V for two of the presets. I definitely would not want that.
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.

Weird. I have the same one, and on mine, pressing a preset button automatically turns off the output.
I thought I remembered the same, so I made sure to double check. The dual channel model turns off the outputs when another channel is selected. All similar supplies I've seen in reviews turn of their outputs when another channel is selected too.

Does your supply turn the output off when switching the channel?

Some more far-east junk, I've been avoiding this BGA problem for the last 20 years, now my sight is starting to fade I'm finally giving it a try. (I have some dodgy DDR RAMs on a Samsung LCD TV to try this on.)

A set of Felo E-Smart insulated screwdrivers.  The daughter-in-law asked Mrs GreyWoolfe what I wanted for Christmas.  She asked me and I said a set of insulated screwdrivers.  Mrs GreyWoolfe reported back simply a screwdriver set.  So since they didn't know what kind of set I wanted, the son and daughter-in-law gave me a Visa gift card.  We just exchanged gifts a couple of weeks ago due to life getting in the way.  So I found a set I liked and purchased it.  Very nice set.  The bits lock up pretty tight in the handle and a simple button push releases the bits.  I have been known to change switches and outlets without bothering to turn off breakers.  Hopefully, these will minimize some shocks. ;D

Good point! Thankfully it does so I don't have to worry as much.

Bought a Cordless Bosch hot glue gun which arrived yesterday, this is a great unit and works so much better than my $7 ebay pos! it heats up 15 seconds instead of 5 minutes and charges from micro usb which is super handy!

Nice, didn't know these were that much faster.
Now I will wait till they equip it with the extra long tube for ultra precise dosing.

Like this one :

Your link doesn't work for me but I found the dosing to be very precise and it made a lot less mess than other guns I've tried due to the retraction mechanism.

Looks good, I like the cordless better tho as the cable was always being in the way in my previous gun.

Yes that is a big salespoint.
But if I understand correctly it only heats up when you press the button, so it is not directly ready but you have 15 seconds?

No it has a power button and it heats up when you turn that on. The temp indicator flashes while it's heating and goes solid on when temp has been reached.

I see you're confused, it is because the board has no rust at all and looks pristine.

But what is it? A high speed digitizer module?

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

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.
