This week, there were two main focuses that were zoned upon:
Biomedical Engineering: this sector focuses on advances in technology in order to benefit the health of the public. In our case, we were building a circuit in order to use different risk factors in order to alert someone of the possibility of Coronavirus.
Electrical Engineering: this sector focuses on the design and application of electronics, with a wide variety focused upon. In our case, we were designing and building circuits, the bare bones of electricity.
There were elevated challenges this week since Henry had Covid and it was a short week because of a holiday.
To start out, we had some experimenting with circuits. (See more below)
We made very quick designs with batteries hooked up to parallel and series circuits just to see how both of them worked. However, we could not leave power turned on for too long, since this process would drain the battery a lot.
On the first day, we were given a college admissions example to design. The short requirements were:
SAT OR ACT
AND
Physical Geo OR Psychology
By utilizing And/Or gates, we designed a circuit on Circuitlab that would model the outcome for these switches being active or inactive. All of the switches were in parallel, so each parameter's switch that was closed would be able to give a proper result.
Series Circuit
Series Circuit
The series circuit worked where the buttons successfully turned on the lights separately.
Parallel Circuit
Parallel Circuit
The Parallel Circuit was created so that both buttons would turn on the yellow LED, so that if one broke the other would still work.
After a lot of painstaking time, we had a prototype design planned in Circuitlab for the Coronavirus detection circuit. There was a lot of issues with trying to get it to function properly in Circuitlab, but after a bit of deliberation, we decided to just go ahead and build it, since everything seemed to be right.
We were able to get the 555 timer to work in order to pulse the green LED at specific times.
An early test of the chips.
We used a LOT of breadboards.
We were able to get our switches and lights working, with just a few problems here or there.
The circuit turns the yellow LED on successfully with one switch activated.
Unfortunately, because of our limited time, there wasn't terribly much specific documentation we were able to get down. We had to stay after class for extra time to finish this.
Circuit Board Test
Circuit Board Test
Our Circuit Board worked successfully. This was a combined effort with Group 9, since we were working after class hours.
