Welcome to calumhealy.ie
I am a software development graduate. Having earned a Bachelor of Science, I am currently looking for work while also taking time to learn new things, particularly in relation to my projects below.
This website showcases my projects, ongoing work, and fun things such as my photography.
(This website is currently still under development :) )
Latest Project Updates
DIY Computer
I tested having two OR gates (NAND gate combinations) outputting to the same line, feeding into a third OR gate. As you can see in the images, only the inputs of the second gate are on, but the outputs of both gates are on. This is the setup for the test. Neither input LED for the first gate is on. However, the final output LED does not turn on all the time, but only when both of its inputs are on. This suggests a voltage issue, which is also seen in the dim first output LED. The rough circuit diagram is shown (simulated in Logisim). This test will need to be redone or redesigned, as the results from this setup were inconclusive.

A Cool Photo I Took Recently
Plane In The Sky
I took this photo in Munster, some time in January, but I can't remember exactly where or when, and I didn't record the aircraft type or airline at the time, so my best guess is this is a Boeing 787. As for airline, I have no idea. A cool photo, considering this plane was probably at around 38,000 feet of altitude.
