It been some time since I’ve updated this blog. While I have designed and made quite a few things, it’s been at the very bottom of my list to update this blog. Anyways, here are a few things I’ve worked on or am working on.
New RTJ gage
So, in an effort to simplify the manufacturing and generalize the usage of the gage I have redesigned it. With 3/4″ of travel it will allow for the use of almost any attachment along with the balls that typically fit something like this.
Still will take some time to actually manufacture it but whatever.
A quick gage for a customer
These were commissioned from a customer for the quick checking of a particular size on a production job.
Nothing too spectacular there.
I’ve worked on a few other things such as the forklift safety system. This device was meant to be attached to the forklift and engage a horn when the forklift went to fast. It was completed but the company no longer required it.
Anyways, time to start some more interesting projects in the future.
I found I kept making and drawing tile sets for little games I wanted to make and I found it time consuming. some engines require a bit of padding around each tile so that when the drawing is scaled, the next pixel isn’t shown from an adjacent tile.
I quickly wrote it in freebasic in under an hour, there’s an EXE in there too if you don’t want to use freebasic or look at the source. very little to it and everything is straightforward. The program will generate a blank tileset with both borders and internal padding indicators. I may write a program sometime that will automatically pad the tiles as needed from an existing set.
In my time making things for my YouTube channel, I’ve made a little series of videos detailing my creation of a crummy pong game. Fact of the matter is that I haven’t done some serious programming in some time so I needed to wet my whistle so to speak. You can play this game here. Quickie Pong!
So, for anyone who wants to view them, here are the videos for anyone’s perusal. Oct 1, 2016 is when the 3rd video is published so, if anyone cares, that’s when it is available.
Anyways, hopefully somebody enjoyed that. If not, you;re welcome to like and subscribe anyways!!! Again, go to my channel 🙂
I’ve decided to start a new Youtube channel simply because I feel as though adding my projects and the things that I like to a video channel will drive me in ways I hadn’t had before. Thus far, I have 0 subscribers (aside from myself) and I’m genuinely curious to see how well I can make a Youtube channel work out. I believe I have some interesting things to share and some boring but popular things to share as well and a new Youtube channel that explores all those things.
Not the most graceful URL but I will get a better one once I get some subscribers and I’ve been around for a while. I will explore things that I do such as electronics, gaming, machining, photography and whatever else I come across.
Here’s a video detailing something mundane, my calculator collection.
So, feel free to look at my channel, subscribe and like a video or two. 🙂
Well, I was looking at my site and noticed that my last entry was November and it was the very project I’m starting to finish right now.
This is my Remote indicator. It’s a tool I developed after having found that standard indicators are a pain in the ass in some circumstances. While you can bash something together with off the shelf parts like say, a Mitutoyo digital dial and a SPC box, that option can be pretty expensive.
Now I’m going to start developing the next version while I test out this one. The next one will be slimmer, more efficient and more attractive. There will be an optional Infrared communication port for it so when it’s sitting inside a deep bore or whatever ,it can still be read.
My new office is filling up, now I need to move some of my test equipment in and start developing. Truth be told though, I have been developing some interesting things and soon I will post them here on the blog again. It’s been a while since I’ve felt like posting about the things I make but it’s always a good time to keep a good record of the things you do.
For the last year or so I have been collecting various postcards and images from Edmonton’s past. My collection isn’t that wonderful or anything but I have some neat pictures nonetheless. Since my favorite thing is to do a comparison between then and now, I will also include some Google Earth or Streetview images.
I find those kinds of comparisons pretty cool. Here’s another comparison from another postcard from the 50’s
And now, I’ll simply post some images from Edmonton’s past that I have a bit of history on
Anyways, I hope people enjoy these as I have many, many more to post. I may try to research the images a bit more closely and give some history on them.
It has been a long time since I wrote a game. This one just took me by surprise as I was playing Flappy Birds for the first time. Having heard that the author pulled it. I wanted to make my own version but different.
Pulling from Super Mario Bros. and Flappy, I came up with this. I started writing it at work today and am now finishing up the levels. Hell, I even made a little title graphic.
Well, it took me about a day to write the game but the levels are another thing. I will update the game as I finish the levels and hopefully someone, somewhere enjoys this game.
Some recent developments, whether they are fruitful or not, have got me thinking seriously about the design of 3D printers, their use and some of their current drawbacks.
Additive manufacturing has come a long way even in the last 15 years when it was just a novelty and not useful for much more than rough prototypes. While 3D printing will probably never supplant ‘subtractive’ methods such as turning and milling for most things, I believe it will be a real boon for strange, esoteric and one-off parts with limited mechanical demands.
This got me thinking about my own design and what I perceive to be some of the issues with current machines all the way up to commercial machines. A couple of those issues are of concern when making a upper-tier hobbyist grade machines for making prototype parts.
These two things are, the effects of gravity on the part when heated or produced, and the effects of uneven heating throughout the process of printing a given part. This will not only increase accuracy but reduce the need for support structures while printing.
Here is a rough pic of my idea for a 3D printer:
Having a heated suspension fluid eliminates the wow caused by uneven heating and the droop generated from gravity when the part is properly heated. By keeping the liquid level slightly lower than the workpiece you can still generate lattices without the fear of them filling in. The inflow and outflow should be computer controlled via electric pumps and valves, this way the fluid can remain hot without having to heat the whole enclosure. Draining from the bottom will partially help ensure that the cooler fluid is drained first. You could even add a filter to remove detritus.
For the fluid height sensor, I would probably try to tie it in with the nozzle height somehow without interfering with the work envelope. The level would need to be maintained very accurately in order to ensure maximum efficiency. For this sensor I would probably use my old design for a viscometer with the two Piezo discs, instead of measuring viscosity, I would just check for fluid contact, for this purpose it proved to be very accurate and resistant to fouling.
For the fluid, it should match the density of ABS fairly closely. Mineral oil or Propylene Glycol might be good candidates. The idea is to have a fluid that is non-toxic, non-flammable, somewhat viscous and chemically inert with plastics.
Fragile hollow objects with no holes (a ball) may become deformed due to fluid pressure. though this would require quite a bit of depth to achieve. Not to mention that the item would want to float.
Structure needs to be very rigid and acceleration and deceleration needs to be toned down as to not allow the fluid to slosh around which could shake the part loose during printing.
potentially messy with fluid being added to the mix.
mechanically more complicated and motion components need to be at least resistant to fluid being used.
Fluid would probably need to be changed with different materials. A fluid denser than the plastic being laid down may cause issues.
Stronger binding to the table is required especially with lattice heavy designs, floating will occur.
Anyways, that’s my idea, posted for posterity. Maybe someone will find it interesting or foolish.
