This week, our group continued with the design of the electrical system. Under Scott Jackson’s supervision, we were able to construct a prototype counting system consisting of a photosensor epoxied to a clear pipe and attached to an electrical circuit constructed on a breadboard. This circuit was nearly identical to the one in the original schematics.
Confident that this design is effective, we have placed orders for the materials required to construct a full scale sensor system. These purchases are being made through Scott Jackson as he has the contacts to get the necessary equipment such as the counter, mounting platform, and various circuit components.
With the electrical system nearing completion, our focus turns to the housing system, and how we will attach the fish counter to the Capilano Trough. For this, Justin will be visiting the hatchery on Friday to make more observations of the site. Key things that we are looking for are whether the trough is magnetic (allowing a mounting system that employs magnets), and its overall dimensions so we can design the funneling system and if necessary, design for clamps to hold the counter in place. The funneling system is the method by which we will divert fish towards the pipe with the attached sensor system.
We’ve also learnt that the time the fish want to move is between 1.5 to 2 weeks, so we have decided to design for an operating period of 3 weeks, allowing plenty of time between recharging.
Once the order comes in, we will move forward with constructing the hatchery fish counter, while under Scott Jackson’s supervision. This is in accordance with the instructions of Mark Rigolo, PEng, Director of Laboratories in the Civil Department, who has approved our safety plan and procedure.
This is impressive progress! Congratulations.
Good to see that you are on-top of the safety issue.
In addition to constructing the device for the hatchery, will you be delivering other items to the client? I’m wondering this because of the impressive schematics you have posted this week. Although it’s not part of the expectations for CIVL 202, would you be able to send me copies of any files you are planning to provide to the client?
Also, in an attempt to get you to set back from the design and construction details of the project, and in consideration of CIVL 202, which is a “technology and society” course, do you think there are societal issues associated with your project? If so, (I would probably argue that there are such issues for your project – habitat preservation, etc), do you think that the engineer has a role to play respecting the relevant social issues surrounding a project?
Again, congratulations on this progress. It looks like a lot of fun to me.
