 It has been too long since I updated this blog space - about 10 months or so; i actuality, the last zikzak hackery was probably 6 or 8 months back, as I started to think about making a case for it, which led me back to the idea of a 3d printer .. and to buy one, or make one from scratch? I ended up tooling around with designing my own CNC machine (cutter) and combine it with a 3d printer (additive) - they'​re really the same machine design more or less, where you cut with one and draw with the other, but the same x-y-z machine, right? Well turns out with CNC you make waste, and little bits of wood or metal are flying off all over the place so you need a vacuum and a shield, and its noisey as all hell. Awesome to be sure, but just not as useful for me, right now. Also, its a lot more stress on the machine to do CNC (lateral grinding) than to just draw out a bead of plastic. Of course, drawing plastic is a whole world of pain too -- thermal control is a nightmare, to heat and cool at just the right spots (cool on top, so molten plastic doesn'​t spooge out of your assembly; hot inside, so it flows; cool again, so that it doesn'​t melt all over the place and puddle, when you want it to stick; then heat underneath, so it doesn'​t cool _too quickly_ ... ugggh). In the end, I built a incrementally better and better 3d printer, and then started merging in pieces from kits since I got less interested in designing my own printer to actually wanting it to be productive... so now I've got a beast half frankenstein thing of mine, with some really nice kit parts to make it work. So there, that was last winters project :) Then summer came.. and well, with a 3d printer, and summer, what things can you do ... so I designed and flew a tricopter and quadcopter. Designed and fly RC machines is really tricky stuff.. but success! ​ I suck as a pilot, but the blasted things work. It has been too long since I updated this blog space - about 10 months or so; i actuality, the last zikzak hackery was probably 6 or 8 months back, as I started to think about making a case for it, which led me back to the idea of a 3d printer .. and to buy one, or make one from scratch?

 --> so time perhaps to make some lame little keyboard demos .. show typing with characters appearing on the glorious 8 bit screen? or maybe a lame '​piano'​ demo like the old 8bit machines always had in their manuals to type in in BASIC.. type a '​a'​ to hear an '​A'​ tone, etc. Hmm. --> so time perhaps to make some lame little keyboard demos .. show typing with characters appearing on the glorious 8 bit screen? or maybe a lame '​piano'​ demo like the old 8bit machines always had in their manuals to type in in BASIC.. type a '​a'​ to hear an '​A'​ tone, etc. Hmm.
