  • I saw just the pan-tilt hardware with motors on df Robot and always wondered what it was for. The screw holes and clip assembly up top looked like it was specifically meant to mount something ... I guess the pi cam was it. Im going to try and get it to aim something different ... But I can attest to the hardware though. It's extremely lightweight and the motors have a gear assembly giving them decent torque for being plastic. Probably very useful in drones or robots because of the weight. Seems reasonably rugged for what it is too. I like it.

  • Well at least we know it passed QC ...

  • Yeah not a good heat conductor ... very much an insulator. I use this stuff extensively in my workplace. Its the equivalent of duct tape in how its used in semiconductor. We put this stuff through metal sputtering tools (high temperature, plasma, and bakes), high vacuum, HF and sulfuric acid etching, it blocks photo litho exposures but is still see through enough to align to something underneath if need be, blocks off reactive ion etching, and is otherwise a great electrical insulator. You can freeze it, its adhesive is not water based (its silicone based) and doesn't require preservation at low temperatures. We even use it for pull strength testing for ball mount pads sometimes. Adhesive cleans right off with IPA or acetone.

    A post below mentioned its use in High vacuum systems, and yes is true that it will give off some gases from the adhesive. A miniscule amount and perfectly acceptable in most situations.

  • That's because they hope youll take their version and spread its infectious non-standardization around out in the business sector. Effectively forces businesses to purchase expensive cad suites because its what you were trained on in college. Its all a big racket. It seems like a deal to you but itll gouge the business you work for later on down the road to make up for it. And your pay will reflect it in some way. Its all one big circle. You should see how much licenses are for businesses to use that same software. And its just XYZ data management! Windows, for example, as a software is infinitely more complicated and costs 1 or 2% as much.

  • I'm wondering some of this also. The hookup guides have been useful as far as individual boards go ... but if you were to stack like the entire Starter Pack, Sensor Pack, PWM, and UART all together ... theres bound to be ones that don't jive because of pin count or something. And as you mentioned ... that's potentially a lot of interconnect and possibly signal loss?

  • These ones sold at Circuit Specialists (https://www.circuitspecialists.com/extruded-aluminum-enclosure-2506h-43.html) say they are designed for 2.5" cards, which is the width of these breadboards. The length though will leave a little play of maybe a half inch. Maybe not a bad thing though if you are looking to mount any type of pot or switch on the front panel.

  • Make them in standard card sizes so people can buy extruded aluminum boxes that have slots they can actually fit in. There is some kinds of Euro standard floating around for PCB card dimensions that most slotted box manufacturers are sticking to.

No public wish lists :(
