What's a good PCB layout software for a beginner? Autodesk EAGLE seems too complex for my dumbass and Fritzing is no longer being mantained and crashes on me a lot.

After my latest solder tip literally crumbled in the middle of a project, I'd like to know what tips y'all use and how you take care of them.

Is it possible to get micro USB sockets that simply have 2 pins for power that my dumbass could reliably solder? Is there a magical keyword to find these on eBay?

Ambrose Burnside posted:"loss leader to undercut their very similar and more established competitors" i would imagine I ordered a handful of components: some pots, ICs, caps, and other small components in addition to 3 rolls of hook-up wire on Thursday like 4 AM. it arrived today (Friday) a little after noon. All these things could probably fit in a 8"x8"x4" box or so with plenty of space for packing peanuts or whatever. The items arrived in 2 different boxes: a 10"x8"x4" or so box and a 8"x12"x12X or so box. Every item was in its own fairly large anti-static bag and individual ICs (I only ordered 1 of each) were in a separate rigid tube that are at least 8" long. Edit: One of the components was a DIP socket that is in its own sealed box that's larger than a ring box that is also in its own antistatic bag.

Shame Boy posted:Try ordering some TQFP packages from them some time, it's insane. I order like, 10 ATMega chips and they send me this massive tray, like 1ft by 2ft, capable of holding like 200 to 300 chips easy, and made of that really durable plastic that milk crates are made of. This is then secured with three thick straps, vacuum packed in an antistatic bag and put in a box with a bunch of packing material. drat those trays eeem handy. Might be worth it just for those.

This is a kind of unrelated aside but that tree figure reminded me of a toy I had when I was young that had a green translucent material on the top of the head/stump and the eyes. I think it was supposed to catch light and slightly give off a green glow. Maybe it was glow in the dark.

I think there's a BigClive video where he takes apart a lithium battery and it ignites. Thankfully he was putting the pieces in a metal dish but burning pieces were still going all over his workbench and around more flammable stuff.

I think that BigClive video with the battery is the only time I've gotten earnest concern from his voice. This includes the video where he was shocking himself with mains voltage as he stepped down with resistors to see if he could let go of the conductors.

Maybe one of you guys could clue me in on a search term to find a connector I need to do a simple project. It involves several RGB LED strips radiating from a central point, much like a clock or compass rose. I need a right-angle male header to connect every other pair of strips to each other so they are all in one series. Here's my crude MSPaint of what I"m talking about : I've tried searching for "stacked right-angle headers" or "linear right angle headers headers" or "flat right angle headers" but I'm not finding them. Surely they must exist. There is probably also a waaay better and smarter way of accomplishing this. edit: Forgot to mention that I can't use right angle connectors meant for LED strips because the ends of the strips are nowhere near each other.

poeticoddity posted:https://www.digikey.com/products/en...e=1&pageSize=25 Wow, that was fast. Thanks! For anyone else that might need these: these Digikey results lead me to a model number to look up which lead me to the ebay keywords I needed which in this case is "triple row right angle headers." I use eBay because I'm cheap as hell and buy headers in 40 pin strips and snip them to the size I need. Unperson_47 fucked around with this message at 04:12 on Sep 17, 2019 |

I've tried this but with homemade "solder paste" made of powdered graphite mixed with various glues, epoxies, and even acrylic paint. If you add enough graphite, the resistance is actually really low and you can paint circuits on paper and such. I applied the glue with a syringe and it hardened in the grooves. It worked but was messy as hell. What a dumb goose chase project that was. I'm one of the most beginner level people in this thread when it comes to electronics so I didn't want to invest in an etching kit, even a cheap probably garbage one just to play around but I do have access to a 3D printer. Nothing I would make would be complex at all. Here's the STL for a simple board for a Raspberry Pi weather station I made with it: Right is for the Pi. Bottom left is for a BME280. Top left was for an ADC that was connected to a wind speed and direction board I also made that used reed switches. It was even more of a mess.

I'm trying to 3D Print some frames to place over LED strips. Any ideas for ways to stop the light from bleeding through the material? Even 100% infill doesn't really help. It's so small that adding metal reflectors seems really difficult. Is there some kind of paint-on metallic paint that reflects 100% of light? This is similar to the LCD-like segmented numeric digits y'all were talking about a few pages ago so I figured I'd ask. edit: I'm going to try just adding some black acrylic paint and see what happens.

I think I want to get into learning how to program microprocessors to make standalone PCBs for little electronic projects and stuff so I don't have to use a RaspberryPi or Arduino and everything's contained to the PCB/perboard.. I don't plan on doing anything extremely complicated (at least not at first); just little LED doodads for now. Obviously. I have no idea where to start really and wonder if y'all could suggest some resources.

The Qt Py is a grown up and shrunk down Arduino that can also run Python (and drive an I2S device... and has capacative touch sensors... and a 10-bit DAC... and and and). Yeah I made a typo myself (or really just used the wrong word) and meant to say I was looking to start programming microchips, not microcontrollers. I was mostly just looking for something of a way smaller form factor really. Everything I do is just to tinker and play around in my free time and I'm not looking to use the least power possible or anything. It seems like what I'm looking for and I will have a lot of fun with it. edit: Also I apologize for editing so much. I am bad about typing things before I have my thoughts all together.
