heatsink to avoid throttling the cpu early on the sponsor of this video altum designer is one of the most advanced pcb design softwares on the market altium has some pretty advanced features which enable collaboration among multiple team members so there is no wonder they are a popular choice in the professional pcb design world check out the link placed in the description below to sign up for a free trial of altium next up i got another one of these small panel mount pir sensors and the circuitry inside these is very simple something like a capacitor divider to provide power to the pir sensor and then the output from the pir is used to trigger a triac but my goal here is to use one of these as a switch input to a smart relay flashed with tess motor so i would end up with a motion activated relay that i could also use to control a light but at the same time have these smarts to control it over mqtt and add other factors into the mix like the ambient light level or varying the on time stuff like that that i can build into my home automation service i know it's not an ideal solution i should probably just use a separate zigbee pir sensor and a separate relay for control or maybe just design my all-in-one mains power dsp NUMBER_TOKEN plus pir plus relay which i might do at some point but until then you'll find the link for all of these products shown in the video description below next up i got a couple of different models of these clips or mini carabiners and this one has a parachute cord style lanyard with a small uh clip on the end while this green one has the belt attachment type of velcro belt so you would carry this on a belt and maybe clip some accessories that you need to carry around these can be handy for those that go camping or hiking in the wild and they do cost so much less when getting them from aliexpress as opposed to the local sports or camping shops you can probably get three or four of these for the cost of getting one locally in a previous mailbag i showed that large din rail type enclosure and now i also got its smaller brother which is probably half the size and can be suited for uh smaller projects like you can build some espNUMBER_TOKEN automation type board that would fit inside the smaller enclosure and clip it to a din rail it's the same average quality plastic they claim it's fire retardant i'm not sure i haven't checked that but generally it it does get the job done as an enclosure especially when you consider the low cost of these units i also ordered this similar din rail mounting style enclosure but this is from a different seller one that specializes in enclosures on aliexpress and let me tell you that this one just feels like it's higher quality the plastic feels a little more flexible uh this one feels a bit more brittle and there's greater attention to detail here like they have these metal threaded inserts for the screws there seems to be a higher quality finish on the mold on this part so you can basically tell immediately that this enclosure is higher quality however this comes at a cost and i probably paid something like two and a half times the cost of the cheaper enclosure for this one but i thought this would be nice to have for a future project it has this smoked
