Day of Depression

25 02 2014

I’ve sunk into a bit of a depression low yet again. It’d be great if I could find a way to just get rid of it. I am on medication and I think that has made a bit of a difference to how low I can sink. I managed to get a load of clothes washed, hung out and brought back in, made a decent healthy meal and got a load of dishes washed today, which would not of happened if I weren’t on any meds. I would have just laid down and gazed off into oblivion all day. Still, it’s a real drain and super annoying. I wish I could just function like a normal human and be as productive as my spirit wants to be. There is so many things I want to do but can’t because the depression just saps all of my energy. I think self-esteem issues and self-acceptance lay at the heart of what’s causing it, but I have no idea how to verify that and regain them if possible without spending money I don’t have on counsellors etc.. That’s all for now, hope everyone had a bit more cheery day than me.

Long Time Coming

13 02 2014

Hey, it’s been a long while since I’ve been on here. To be honest, life got in the way, including uni, knowledge of my impending death (don’t worry, it’s been sorted out for now), depression and kids. I haven’t done anything new since my last post but am hoping to simplify my life a bit so I can fit something in. From now on, I’m going to treat this as a type of diary and just write about my life. Hope you can join me for this journey.

Production Grinds to a Stop During Holiday Period

23 12 2012

Christmas has meant I haven’t been able to spend any time on my projects. Progress will resume in the new year.


30 07 2012

So I haven’t fallen off the face of the Earth or anything, mainly due to the fact that it’s round. But have experienced a change in direction. This post is going to be a bit of ramble but I will try to make things as clear as possible. The main thing that has happened since my last post is that I have decided to shelve the Open IC project for the moment. This is due to a few reasons

1: I found that a group of people have been attempting a similar thing.

2: I have fallen victim to the dreaded procrastination virus and

3: I have taken on two new projects that I have been wanting to do for a long time and that I have more determination to finish.

The first of these projects is the one I have been focusing most of my attention on as of late and that is developing a high altitude balloon launch platform for rockets. The second is an electric assisted enclosed recumbent bicycle. So, for now at least, you will be seeing updates on these two projects as they develop. The next few posts will be a catch up on my progress so far.

Hope you stay tuned for more.

Open IC Preliminary Testing

28 02 2012

I have been looking into the processes used by the large IC manufacturers to do photolithography. It appears that they use a coherent light source, usually in the far UV spectrum from what I understand, that is shone through a mask of what the current layer being etched looks like. The light that is let through then passes through a series of optics and mirrors that shrink the image down to the size they are after.

Since we are talking about UV light here, the optics would have to be made from quarts. This is due to the fact that standard optical glass is opaque to UV light. This makes the optics very expensive. My idea is to discard hopefully all of the glass and replace them with convex and concave mirrors.

Also, Instead of making up a mask for every layer, I had an idea that a laser of a suitable frequency could be used in an assembly similar to a CNC laser cutter and switched on and off in a manner that would result in the appropriate areas of the photo-resist being exposed.

To test my ideas I am going to dust off my old Newtonian telescope and make a small CNC laser plotter from a couple of old CD or DVD drives. I will then shine the laser down the barrel of the telescope and put a photo sensitive PCB near the lense to see if I can get good results from visible light and to get an idea of what the limitations of this approach will be. Will post more when I have a design made.

Open IC Project

28 02 2012

In recent times it has come to my attention that there is a severe lack of open source integrated circuits available. Even open source transistors and logic gates are nearly impossible to find designs for let alone available for purchase. As such I am throwing my towel in the ring and am going to help out.

I have found that there are some design files available that have been made open source for micro-controllers but, if you want them, you have to either emulate them, make them on an FPGA, or pay a hefty some for an IC manufacturing plant to make you a small run of them. Since the design files and software are available, I am going to start on the design of an open source IC fabrication set up using the traditional photolithography process. I have no idea if this will be feasible but if you don’t try then you will never know.

Here’s to progress.

Some Inspiration for this Site

These are a couple of videos that have inspired me to make a contribution to the open source community.
