3d Printer Part 4

I discovered I have a bunch of 74ls08's laying around and those are AND gates- bonus! That make's it simpler- see my new diagram(just imagine those inverters are not going to be NAND gates hahaha)


Here's what it looks like blinking in sequence as it should(too bad I didn't get the other chip in the picture- whoops):


Maybe tomorrow I'll wire the motor to it.

vBonsai -Video Tutorial at the Bottom!

A menacing looking vine grown on my phone from an algorithm I wrote for my next android app:  Here is the same algorithm with branches, texture, and leaves! I drew the leaves in Microsoft Paint, but the bark is real bark from a picture edited in Gimp for the shadow, seamlessness, and color(And you can't see if from here but the bark of that tree was covered in cicadas). Note the draw function knows when to 180 the shadow in the right direction so shadows aren't on the top of the branches. Not all of the trees look this good. Many are scraggly or unbalanced. Meh, it's a work in progress! YOU HEARD IT HERE FIRST! Got the gameplay mapped out. You will grow your tree from a seed and care for it and shape it to your whim using real(virtually) bonsai techniques. Watering and feeding schedules will be determined based on seasons and whether or not the tree is in training(stress) and health, etc Most recent emanation:  Whew! The ...

I think I have 200 accounts scattered all over the internet including 10 or so forums, 3 facebook accounts, a twitter account, google plus account, like 10 emails, 50 places I have ordered from- on and on! Why not add a sqeeqee account? I am not going to say that I am too lazy(as it is en vogue to say so) to check it out because I am not. I just have other priorities. Such as writing about something I am not going to research and know nothing about. Now THAT is important! That being said, I know mostly nothing about Sqeeqee.com. What I do know is that it is yet another social network that seems to be an amalgam of facebooklike features and ebaylike features and several others I am unaware of. I found it as the result of my marketing efforts for FlaTank and joined up. The appeal that it has for me is that it is still in beta testing. I am still seeing php errors in the ranking box sometimes and the claim to be 99% error free at this point. Usually stuff like this escapes me unti...

3d Printer Part 14

Tonite, I modified a few reset buttons(dpst) from old computers from normally open to normally closed. Those switches work nicely because they come with the Dupont plugs that fit my RAMPS shield. They are going to be used as end stops(currently I'm just using jumpers) The end stops are needed to establish an origin in the Cartesian geometry the printer uses to to determine where to put plastic. It won't be to long before I can start calibrating and then I can run the slicer program. Before I do that, I'm going to move the gantry back a couple inches because in my lack of planning(true intp), the build bed doesn't get enough travel under where the j head is going to traverse. I get the slicer dealie running, that'll be a cool video! Imma have to find some nice funky music for it. I know I didn't mention I was going to do this but hopefully I can put together the protection circuit for my sound-card oscilloscope this weekend. I've wanted an o...
