Still waiting on ICs and stuff. Meanwhile I got the mechanical parts in and 3d printed the inputs for the switches and stuff. That is giving me a sense of order on the breadboard 😊

It took me most of the afternoon to get KiCad hooked up to github so that I could version control my project + "integrating" it with Mouser which is where I'm getting my parts (to ensure I get the right sockets, etc). Not sure which of the 2 was...

Then there is this guy 😂 What I have done so far is to 3d print some helpers like this one I also ordered some smd-to-dip for 0604 an 0805 capacitors and resistors of different shapes so that things like debouncing stay all in the same row...

I'm certainly a criminal here and Paul will probably cringe, but I've never cut that trace and I have powered boards with both sources simultaneously due to my application. (Normally powered via a 12 volt supply, but frequently powered via USB...

For wiring a semi-permanent breadboard setup, I recommend using the U-shaped jumpers like shown below that lay close to the board. The wire is heavier duty 22AWG and provides more solid connections. While a little more trouble to initially...

Treat the schematic as the single point of truth and build up the breadboard circuit from it, perhaps crossing-off nets from a printed schematic as you go to avoid missing anything? You can build up a wiring diagram the same way on squared paper...

There is software like https://app.cirkitdesigner.com/ https://www.circuito.io/ ... and others maybe that helps?

Cool. I’ll check it out!

Hi everyone! I just got stated with embedded and I suppose my starter project it is a bit big. It is a universal testing machine and uses over 30 of the Teensy pins plus there are other surrounding ICs and components plus a USB interface to a...

Simplicity. Embedded hobby projects usually don't have gazillions of files and name conflicts therefore namespaces are rarely used. Historically embedded projects did not use C++ at all because modern C++ with templates, std lib might bring...

DMM on continuity test it should see NO CONNECT. It only takes a tiny shard to complete when not wanted - that is not enough when needed :(

Hmmm... in the project that I'm working on, a universal testing machine, the stuff is simple, move this, measure that, record stuff, show some graphs and calculate some properties. Though there is a lot of UI and a fair number of inputs as in...

Hi everyone, I'm doing my first embedded project and I noticed the practice of programming mostly in C and scoping things out by using static declarations inside the cpp file. That was a bit unusual to my eyes. I was thinking of still using...

The ohmage is close to zero. I'll get that little tail out... need a pair of magnifying glasses, as soon as I get it out of the breadboard. Right now it is in a mess of wires :) Thanks!!

It still works - powered by USB that is good. Looking at the linked page it shows the right spot and seems it has been hit in the picture. One note there is: "Use a DMM to verify there is no continuity between the pads." Apparently there is...

Hi, Noob here! Objective: I want to program the Teensy 4.1 while powering it from the breadboard. Issue: I cut what I thought was the VUSB trace, but I'm afraid that is not the case given that when not in the breadboard and powered via the USB...
