But I’m also a bit worried—can this setup be trusted with my phone? Is it safe enough, or should I be concerned about risks like overheating or damaging the battery?and I’m wondering—can this power bank be brought on a plane? 1 0 replies

How do you compile Engineering Drawings with non-smart part numbers? I've worked in several industries and always had a pre-defined smart part numbering system established. This has always allowed me to create parts, assemblies and drawings that nested easily and understandably when I released packages of drawings for production. I'm currently working in a business and part of the team trying to make a major upgrade to our Engineering processes, part of which involved standard part numbering, controlled by Vault Pro. In order to accommodate all departments who, historically, have all utilized their own file naming practices, we have... 1 11 replies

Viability of Engineering Journals I'm currently in a senior design project where one of the requirements includes "live journaling," or just writing down everything you are doing / thinking about WHILE you are doing something / thinking. While this gets live accounts, it greatly interrupts my workflow if I have to constantly to write stuff down. I understand the potential necessity of such journals because when a replacement comes, the replacement can read through the journal and potentially be quickly up to speed for the projects that are being worked on and consider... 3 0 replies

Calculator for engineers of a certain age... As I get older, I find it a pain to get out the graphing calc with a hundred teeny buttons for every little thing, and I don't always have my computer nearby. Is there a desktop-style physical calculator that's just there in the real world and that I don't have to open a damned app or navigate to just to do basic stuff? Maybe some basic scientific notation and unit conversions? You know the ones that tax accountants have that have a couple extra functions useful to them? Like... 5 20 replies
Software Engineering Related Fields and Regulation Hi Everyone, I have a traditional education in Chemical Engineering and Applied Mathematics. In the early 2010s, I mistakenly believed that software engineering and computer science were not "official" engineering fields like civil, electrical, mechanical, or chemical engineering. This perception stemmed from the absence of a physical component and a focus on different mathematical disciplines. For example, traditional engineering heavily relies on differential equations and classical physics, whereas software engineering emphasizes discrete mathematics, algorithms, and graph theory. Now, working in the software industry, I've come to appreciate the rigorous... 2 0 replies
Engineers on Industrial Sites I am just wondering what other folks work place processes are for confirming compatability of parts. We have an overhead crane that needs a new hook, procurement person 1 reached out to the OEM for a quote, OEM responds that it is no longer available and proposes an alternative but asks for a confirmation of the equipment number. Procurement Person 1 fwds the email to Procurement Person 2 to review. Procurement Person 2 fwds the email to me to answer. There has been no processing showing what we asked... 1 0 replies
How do you guys organize all the daily tiny fires that come up? Looking for a free software solution or other solution for this. I have my main projects I work on that are easy enough to track. But I constantly have people coming in my office asking for little things here and there. But it's constant. I try to write it all down but then sometimes the paper I wrote it on ends up in the garbage. How do you guys organize all your tasks? I'm forgetting things when people bring me 50 problems a day.

Does anyone else feel like they waste their time because half the things they do even if requested get pushed aside? I personally do a lot of automation of reports/actions for a tool I support to help my team and provide transparency for quality goals. However it feels like everytime I put time (hours-days) into actually developing a solution it gets waved away/shot down by a more senior engineer.....even if its something requested by them, usually because the tool honestly has some shit design (no api overwrite for things that can be done manually using the UI prompting workarounds) honestly makes me wonder "WTF am I here for if apparently... 5 19 replies
Looking for ways to automate adhesive weight measurement in Lamination (water based Ahesive) Hi everyone! I work in the food industry, where we manufacture bags with bone guards designed to prevent meat bones from cutting through the material. Our process involves applying a film onto a polyethylene roll, which is later converted into bags during a subsequent step. To ensure proper adhesion, we validate the process using two tests: measuring adhesion strength and checking the adhesive weight to verify proper application on the surface. I’m looking for ways to measure the adhesive application automatically during the process. However, the challenge is that... 2 5 replies

Sourcing BLDC Motors for a Robotics Startup Hello everyone, I run an early-stage healthcare robotics startup, and for quite some time we've been facing a challenge in sourcing actuators for MVP development as well as for initial client-units. Specifically, we need geared, high-torque, pancake BLDC motors (similar to MIT Cheetah for reference). Until now, we’ve been using motors from a Chinese brand called MyActuator. To be slightly more specific, we are talking around 20 Nm (geared). We’re looking to transition to a European supplier, and we’re only interested in the mechanical part - we build our... 4 6 replies
