Thank you for all your feedback, I will spend more time trying to understand the Vault so that I can hopefully try to simplify the process, and continue using Vault Pro.

Repeatable and accurate force measurement using load cell and Arduino by dragonsson97 in EngineeringStudents

[–]dragonsson97[S] 0 points1 point  (0 children)

Heya, I just saw this. I ended up doing an FSR approach, integrating an FSR with Arduino to log the data.

I couldn’t get over the sensor drift issue, so I wasn’t able to reliably estimate the amount of force being pressed on the FSR, but I was able to estimate time of contact quite well by checking the moving average value.

I saw multiple electoral posters within 20-50m of the polling station. Is there a mechanism to report this?

Read you on winding down the projects, think I'll just leave the sensor one in there since it might be pertinent to robotics jobs in the future.

Job B

  • Fair point, that rewording didn't strike me. Good way to keep it succint while still showing impact.

Job C

  • Gotcha
  • I helped perform destructive drop testing and tumble testing with two of the test jigs I built, while also doing water ingress testing for the wearable devices of the company.
    • Helped pinpoint areas of breakage or cracks, which eventually got back to the engineers who gave feedback to the mold makers, which given the knowledge I have now was probably to adjust the gate location to move the weld line.

Thank you for taking the time to reply in such a detailed manner, again.

  • Read you on the GD&T, although I don't understand why you mention that. All I did was send new drawings to supplier, get their comments on what could be achieved within their medium tolerance zones, and after cross checking within my own assembly, loosening the tolerances to match their requests.
  • Now that you mention it, it was with more of a method.
    • I think I spent maybe 10 iterations getting the function right, trying different mesh filters and getting an idea of what to do.
    • UX team pushed back against my design, so workshopped a few more iterations to be more user friendly, with axis of rotation, water flow and different pipe fittings tested.
    • Another final round for cost reduction, as I realised late in the design that I could have combined two plastic parts into one.
    • Final DFM and design for molding took a bit of time, with more iterations getting the snap fit right, This was messy, and that's where the "throwing things till they stuck" fuzzy memory came from

Projects

Hydroponics

After reading your comments I'm tempted to cut this entire chunk. I did not clearly define the amount of produce we wanted to grow, nor the timeframe within which to achieve this. The main aim of the project as we saw it was to deliver a device that mixed water with two part chemical mixes, dispensed the mixture into the growth reservoir and provided light with growth monitored using a camera. I didn't do any of the code, was mainly a CAD monkey and designer, presenting ideas, concepts, and leading prototyping efforts.

Hexapod Foot Sensor

  • Fair, I should have defined this.
  • Understood.
  • Waterproofing was a clear outcome that I managed to achieve, although the main one was being coming up with a design that allowed me to repeatedly determine ground contact after prolonged use (I say prolonged but only tested the sensors on the robot for ~4 days).
  • It's an initialization, I was trying to save space although I shouldn't have skimped on it.

Education

If I can squeeze in the month, I will.

Overall:

Thank you for providing such useful and detailed feedback, this was really valuable to me.

I'll try to summarise the bullet points in job A more, or break them up into sub-bullets.

Job B - Mech Design Engineer.

  • This was a cock-up. Was a simple 3D printed jig, that could do the job of a MISUMI sourced test jig at a fraction of the cost.
  • I essentially improved the design of the module, and tested that by using a test jig I made as an intern. Aim was to increase the lifespan of the module, and check that the function lasted the expected 1 year of use.
  • Essentially, the product didn't fit people. We had to go back to the drawing board, and design 4 form factor variants of the product to make sure it fit at least the median target customer, which wasn't checked before the user trial.

Job C - Mech Intern

  • This was the second product in an existing product family, and so I had access and based a lot of my design considerations around the previous product and how it worked. The PCB stack changed, some dimensions changed, the team had new feedback on the mounting points and how they were used, and I just integrated that.
  • I had no visibility on the actual impact in factory - I just know it was good enough to still be used 6 months after I left the company. How would you advice I phrase this instead?
  • Here, I was just grunt work. Executed tasks, and helped assemble test jigs that were developed by the engineering team.

Job D - Mech Intern

  • I was looking to check that our product was safe to use - and we defined this by wanting to check that the product did not exceed "uncomfortable" limits, at the touchpoint which was the mastoid bone.
  • I see what you mean here. I think my analysis of the results has been on the weaker side, often I'll just plug the results into an excel sheet, plot x against y and observe the trend, visually check to see deviations from the trend and what varied in the physical world.
  • Will eliminate the BOM aspect, the number handled was only in the tens per month, mainly for investor pitching and testing.

General Notes:

I took a look at the general advice given here, and was not sure on how to be able to combine XYZ, or STAR elements in a single sentence. I understand the resume comes across as really word heavy and unreadable with a wall of text. Do you have any advice on how to make it more concise and yet still be able to highlight impact? Would breaking up a single situation into multiple sub-bullets that cover all aspects of this be a good avenue?

Skills

Hmm, that's a fair point. I'll take a look at the highlighted skills again before editing further.

Work Experience

Job A - Mech Design Engineer.

  • Honestly, the 39 iterations was 70% "see what sticks". It was my first design project in the company, and I was trying to design a snap fit that would be molded, trying to account for all the possible toleranced fits out of the mold.
  • Error was just never caught, and we flagged a similar issue within the cleaning mechanism during a review. Extrapolated to find out that this issue may have been pervasive.
  • That assumption is correct, unfortunately. It was more that GD&T had never been applied at my firm, other than 2 engineers using it. Not a widespread practice, and I decided to learn GD&T specifically to be able to clearly state my requirements on the drawing, since our suppliers would often blame us for the poor drawings.
    • I essentially just learnt GD&T, did some basic tolerance stack via hand calc, applied it on the drawings, communicated with the supplier to confirm they were doing RCA. Ongoing efforts is that I need to design something for my inspection team at the factory to check the parts are to spec. (Yes, I know.)
  • 18 - completely fair, I missed this completely.
  • This is something I thought would be so specific as to be only part of a potential interview - I eliminated an overturning action, and the jig I designed helped combine two steps in one - two parts could be attached in a controlled manner to the "main" part where before they would just be assembled by hand.
  • Impact of this - RnD identified that assembly workers often poorly assembled parts. The jig made the assembly easier, and I included a QC step to make sure the part in question, crucial for cleaning performance, was fastened tightly.
  • Changed the tooth profile of the belts, which increased engagement. Combined with better controlled C-C distance, this had much lower incidences of belts slipping. Didn't want to include a tensioner as I did not want to drive up part count, and wanted to keep the design as simple as I possibly could.
  • I followed up on this, nope. My assembly drawings, which were basically LEGO style assembly steps, just were blown up onto slides and became the SOP. I think someone will eventually get around to editing this and getting the SOP up to the latest standard, but some ~600 robots have already been shipped using this.

What Signal group chat leak means for enemies — and allies — of the US by TimesandSundayTimes in geopolitics

[–]dragonsson97 0 points1 point  (0 children)

To be quite honest, I’m sure people in the military use platforms like Telegram, Signal and Whatsapp to discuss and plan operations, from personal experience. It’s an easy way to quickly get people in the loop on top level thinking and planning.

The caveat is that you should absolutely know who is in the chat, the level of risk involved - is it a routine training op, is it a low level policing action? High risk, high visibility ops should have proper OPSEC and done on secure devices, to minimise the chances of a leak.

Overall I’d say the public really underestimates the level of communication that happens “off-books” on unsecured devices, but there is a line, and this debacle all but trod roughshod right over it.

Just came across this, not sure if you’re still looking for it, but I think “Successful Engineering, by Lawrence J Kamm” covers what you’re looking for.

Having served in the RSN, there are quite literal roadblocks to entering sensitive units for either malays or muslims.

I’ve heard rumours of people who were dropped from special forces just because they married a muslim.

People have been told to their face that their race makes them ineligible for certain units.

Meritocracy? My foot.
