Clock project for sophomores

So proud of my sophomores today, they all chose the Digital clock project. Is is very advanced project for there grade level and they did a great job bread boarding the circuit, milling out the PCB and final assembly. We all learned how to mill out a PCB on the T-Tech 5000, this was a brand new machine for the group and they did great! Hope to see more independent projects in the future.

Student Made Video

Very proud of my seniors, they worked on a time-lapse video for the shop to demonstrate a project in exploratory. This kit in an inconspicuous place with light shining on it and it remains perfectly silent, however, as soon as the light is turned off the kit emits a high pitched irritating tone! When they turn the light on again to look for the culprit it keeps silent again! Easy to build and loads of fun to use.

A fully detailed instructions on how to build this kit is on the link below

Breadboard power supply project

This project is for the sophomores, below is an example.

Here is a very simple breadboard power supply kit that takes power from a DC wall wart and outputs a selectable 1.2 to 12 Volts regulated voltage. The .1" headers are mounted on the bottom of the PCB for simple insertion into a breadboard. Pins labeled VCC and GND plug directly into the power lines.

There are two pins available within the barrel jack footprint. Any stripped +/- DC supply can be connected instead of the barrel connector.

NEW SMT Project

Hello, great start to the new school year. This post is for my seniors. Thanks to our advisory board we now have the equipment to build and repair Surface Mount Technology. Over the summer I have developed a SMT blinking LED kit, this is so we can learn more about the SMT soldering and repair process. Hope to have a great year, your partner in success MR. J
