Student Chronicles

The last circuit that I worked with was the Microcontroller Project Alarm Clock which was submitted this afternoon. It was supposed to be an alarm clock but we didn’t get to finish the program for the PIC16F84A. We only came up with a digital clock.

We stayed in Eric’s place yesterday to finish the circuit we have started couple of days ago. The first circuit we constructed was rushed because we need to show our hardware last Thursday. We were given until Monday to finish the software, which is quite difficult to program. The circuit we finished was not that good. We have to spend the whole Sunday afternoon to trouble shoot all the faults in the circuit. A lot of the contacts at the back of the circuit were shorted. Opep worked on the trouble shooting task while Eric worked on a new design. (And I went sleeping ‘coz I was not doing anything.)

Around 8pm, we decided to create a new circuit because we thought that the old circuit was hopeless. We had to rush back to school to get the design printed since there were no laserjet printers available nearby. After few hopeful attempts of getting the tracing paper fed into the printer, we were able to print our design.

We used up two cuts of presynsethized boards for the circuit. The first one failed, either the developer solution was too concentrated or the light exposure was not enough. The second one was successful and we were able to start working on the circuit. We stayed there ’til midnight. I was the one who worked on the soldering of the components but I left before midnight and Eric had to finish the project.

We were able to submit the project the following but we didn’t get to finish everything. There were some features that were not applied.

Note: This post sucks. I’m sleepy while writing this. I have no plans of editing it either. Pasensya na po.
