smander.com - CE for Makers

Meet me in May, in Prague -czechia, Vienna - austria, Berlin-germany and Lecco-italy. Of course I have @E14Community and @SmanderCom swag with me.

@yacineMTB Most accept pyVisa commands , here is how to do it: youtu.be/1HQxnz3P9P4?is…

I need an oscilloscope for FPGA dev. Is there one out there that I can control through a programmatic API or do I need to build my own

@eevblog To often certification/testing cost gets overlooked. It's part of the cogs /part of the dev cost.

@robin7331 @fishPointer I second wera, the budget alternative for me is multicomp, was worth getting the main ones i use in good quality

@fishPointer Non electric? I‘d always prefer a full screwdriver instead of wobbly changeable bits. Get a set of Wera drivers for philips, torx, flat and hex. Keep your set for the fancy stuff you only need twice a year.

what is the best screwdriver set? this one sucks

@1llegalEngineer @i2cjak Nah its mostly just vintage tubes , a bit of rf, but that osram lamp might be the only HV/HC stuff

@SmanderCom @i2cjak Do you have any high current stuff? Need it right now and willing to pay

every mad engineer post: "does anyone have this extremely dangerous piece of lab equipment for making gamma radiation? danke. also the customs officers will execute me if they see you shipped it to me"

@1llegalEngineer @i2cjak You are the one lighting the stove.

@i2cjak Bro did you need to cook me like that😭

@1llegalEngineer @i2cjak Muahaha! I'll catalog and list some of this stuff. Eventually. Likely end of the year. And yep one or two sizes down from the photonicinduction/styropyro ones. So hold please.

@SmanderCom @i2cjak Hi is that an Osram Xenon light? Willing to sell it? Also interested in any power electronics you would be willing to sell

@reprinted3D It all boils down to: are your parts acting as expected or are they typical cheap crap ? in such a case anything can happen. At least limit the psu. Cheap buck converters are also often an emc nightmare in case the thing is glitching you know where to look.

I'm connecting this to a WebCam to provide power only. It's running off a diffeent buck converter, drawing power from the printer's PSU at the moment. This will be independent of that PSU, and I just figured it would be easier to use a USB power-only cable from the PSU to the camera, than to wire it directly into the lugs on the PSU.

Question for you smart people: Which pads do I connect if I want to supply 5V power on this connector? I would think the D- and D+ (cause "+" and "-"), but there's also a "V" (for voltage?) and "G" (for ground?), so I'm confused.🤔

@i2cjak Not needed, but thanks for the heads up

if you route traces on the inner layers of your 4 layer boards i have zero respect for you

@reprinted3D If the device expects negotiation it may refuse function. With the cc lines via 5k1 you'd set it at 5V@whatever amps available. Your supply should be at least current limited. In yoir config its up to the device to not kill itself/start a fire. Usb wants control from both ends.

@SmanderCom If I've got power coming out of a buck converter at 5V into this connector, would I need to be concerned about that?

@Icalbert101 Scan the shell with a flatbed scanner and trace the compound curves.

how do you model something that doesn't have a single straight edge?

@DanielBogdanoff Let him learn.

BRB getting my popcorn out

The first GetSmandered participants are flowing in! Congrats on comitting to get your product to the EU market compliantly safely! #opensource #CE

@MarlinFirmware @lcamtuf We do.

@lcamtuf Cull enough of our fancy features and our 3D printer firmware can run within 32K of Flash and 2K of RAM. Well, older versions anyway. We hope somebody somewhere finds this level of efficiency useful!

I'm speechless, that's not even enough for node.js

@no1089 Its more likely a "our product is not compliant and we know it-please no reporting"

@SmanderCom Haha, they probably thought it was worth a shot! Not that I think enforcing Aliexpress warranty for a <€3 item will get you anywhere.

Random Aliexpress find of the day I like this warning: "Product restrictions: this product is specially designed, difficult to assemble, limited in size compatibility, and can only be purchased as specified by professional engineers."

The emails have landed.

Applications will close soon.
