Divergence Meter Project

Edit: It’s complete! Click here to go see it!

I’m currently making a divergence meter replica based on this guys design

Though of course I have added my own twist to it and have some added features.

The main differences are:

  1. Additional Features:
    • 5 switches possible! Could be less if you tweak the software
    • Buzzer/Speaker output 😀 hurray for alarms in the morning
    • Light Sensor to detect night time to conserve power and extend Nixie tube life (could probably act as a basic motion sensor with some software magic)
  2. Improvements/Slight changes:
    • Should be able to fit 2x9V batteries instead of one so more portable cosplay time 😀
    • Should be able to fit 2xAA RTC backup battery so it keeps track of time accurately for theoretically over a year.
    • Interrupt based instead of Polling to conserve even more battery
    • Uses the larger but cheaper and more available version of the HV5622
    • Integrated switching power supply instead of a bought module
    • Uses an AVR instead of a PIC (I chose it because it can be reprogrammed by AVR tools and a PICKIT2 if you happen to have any of those)
    • Mostly SMD parts to make look all good when your showing off the innards XD
    • Miku silhouette included
  3. Limitations:
    • Can only use the DS3232 RTC and not the DS1307

Other than that it should be largely the same 🙂

Here are some not so 3D 3D models :3

Main Board 3D Model:

(I didn’t know what to add in the battery area so i just stuck a Miku silhouette in there :3 )

Nixie Tube Board 3D Model:

Just to let you know I don’t even know if I can do this, so don’t get your hopes too high lol I just wanted to share this with you all~~~~~ I got most of the parts but I’m currently waiting for the PCBs to come from the fab so after that I’ll begin assembling it 😀 I hope in time for the summer anicon so that I can show it off :p oh and if you want you could give out some ideas that I can implement in software (not in hardware cuz thats already set in stone)

NOTE: The divergence meter is a fictional device from the anime Steins;Gate, it’s used to calculate the Attractor Field of a universe/timeline so that they can be differentiated. For more information go to http://steins-gate.wikia.com/wiki/Divergence_Meter

Playing with JavaFX

It’s time to learn how to make GUIs for my programs and I was thinking if using Swing till I found out there was a newer package for making GUIs and here I am trying to learn how to use JavaFX. I guess I will start with a simple phonebook program and work my way up 🙂 I use IntelliJ for my coding and honestly it is way more awesome than Eclipse.

And yes followed some tutorials so very unoriginal, but hey at least it’s a start.

Blast from the past hardware: ZIP Drive

This is a series of personal thoughts about the old hardware that we have in our hands.

One day my professor gave me this old box ( He was cleaning up his office since he was about to leave :c ) and inside it was some ancient hardware, maybe most of you recognize Hard Drives and DVD Drives, some of the more luckier ones the Floppy Drive, but I have something even less common —– the ZIP Drive. Yes it maybe more new tech than the Floppy Drive but it is still pretty old and  more rare than it.  Read More
