Forget Me Not: Episode 11B - Soil Sensor Design
There is no major progress from my last post. I'm waiting on parts. I mentioned previously that I used a portion of my budget to stock general parts like:
- Resistors
- Capacitors
- Inductors
- Fuses
- Connectors
- Diodes
- Transistors
- and the like
However, I waited until my second order to purchase these items because I needed to acquire the major components of my design first. Here I should add an obligatory kudos to dragonstyne (Steve) for his insightful comment to me when I revealed my initial Gantt Chart (project timeline)
He was completely correct, and I think his comment shows his experience in procurement. I think everyone involved in RoadTests has noticed the comments about heavy volumes at the warehouse and expected delays. Delays are a part of engineering, and a good engineering plan can be adjusted to account for delays. The guy I work with just ordered some vacuum pumps and the lead time is 1 month. It didn't phase him a bit and he adjusted the timeline so everything will still be on schedule. However, I think my inexperience in project planning shines through here because my project doesn't have this quality. I've been working in industry for 1 year and 4 months now, and none of my projects have been on-time.
If I recall correctly, somewhere between my first and second order Newark initiated the same day shipping policy. I think this may be causing the RoadTest delays, but that's pure speculation. There are 15 days left in the challenge, and I haven't been able to work on the air conditioning switcher yet. I want to produce a document for this design as well, so I have to decide when to stop designing and start writing. The purpose of the document is to completely, and transparently release my work into the public domain.
