In this article we’ll discuss using your character turnaround to create a base mesh. While I won’t be explaining in detail how to use Blender – that’s beyond the scope of my experience – I will be introducing important terms and concepts that you can then use to find more knowledgable sources of information. So let’s get started.
Welcome back! So you’re interested in making you’re own custom Halloween costume. If you weren’t able to find some Pepakura models already created, you’re going to need to design and model it yourself. Unless you’re an amazing sculpter who can imagine a great 3d object in empty space, you’re going to want some type of 2d references to work from. Doing some prep work up front can save you a lot of time down the road.
Hi there! I’m relatively new to W88 and was asked to blog a little bit about some things I have going. I have an Arduino sensor project I’ll be writing about later as it gets a little further along, but seeing as Halloween is right around the corner, I thought I’d start with designing and creating your own Halloween costume.
The design I’m going to be shooting for will be made out of EVA foam and should be relatively inexpensive, pretty durable, easy to work with, and not require a whole lot of tools. However, I’ve never done this before so these posts may just be a documentary of my crashing and burning.
This is another breadboard setup to test a component – in this case an LCD display.
This was another submission by Workshop 88 member Jim Williams to the What’s on Your Breadboard series. (Seems like Jim has an awful lot of breadboards.)
Workshop 88 was gifted a large set of these LEDs in a green plastic dome. Jim posted a photo of a breadboard he set up to get the LEDs to go around in a circular pattern. Thanks, Jim!
Last Thursday I read on Dangerous Prototypes forum about doing making PCBs by printing on vinyl and heat transferring to PC board, then etching. Vinyl was reported to transfer 100% of the toner easily, better than the sheets designed for the purpose. Since I was in need of a board, Andrew had recently gotten some vinyl at the space, and there’s a laminating machine there, it seemed worth a try.
The process is simple: laser print the circuit on some vinyl sheet that’s glued to a piece of paper, then run both the printed piece and a blank board through the laminator to transfer the toner to the copper. Paul Reich just finished a circuit board design that looked pretty challenging to etch, so that seemed a good test.
Initially I worried that putting the vinyl through the laser printer might be a little risky. Running a few small patches through didn’t show any obvious issues. The vinyl for the vinyl cutter isn’t ideal: it could be a little thinner and it’s nearly opaque so it’s hard to see whether the image is on the board.
The first quick test was quite encouraging.
Although far from perfect, in the areas that transferred the detail was quite good. Since the board hadn’t been cleaned and the board was only run through the laminator once, results were better than expected.
Saturday back at the space, I thought to try some other materials instead of borrowing the supplies for the vinyl cutter, and try some ways of cleaning the copper. Browsing the hardware turned up some Con-Tact low-tack shelf paper that seemed to be vinyl, as well as steel wool and polishing compound to clean the copper.
The shelf paper didn’t work out, as it didn’t stick to paper enough to go through the printer. Steel wool and polishing compound both appeared to clean the copper pretty well.
After some further experiments, Paul and were able to make a couple of double sided boards that were good enough to use for some of the tests we were hoping for.
Workshop 88 member Doug Bradbury showed off a simple “stoplight LED” project that he had on a breadboard as a leftover project for work done for a client. Thanks, Doug!
What’s on your breadboard?
Workshop 88 member Jim Williams shared these breadboard photos for our “What’s on Your Breadboard series
This board had a electret microphone with preamp on it, for use in an arduino class that we ran. As you can see, he eventually put the circuit onto a PCB.
The second breadboard shows that sometimes a breadboard is just a convenient way to connect one sensor to an arduino. In this case, it was an ultrasonic rangefinder that Jim wanted to test with the arduino. He reported that it worked well.
“The camera is too new to hack, so I made a holder out of 1/8” plywood for an RC servo that would slip onto the camera body and could be held in position with a couple of thumbscrews. An Arduino micro controls the servo and handles the timing. The project is still in the breadboard stage. I’ll probably add an LCD and either an encoder or joystick switch so that I can change the time interval when I’m on the road.”
Thanks, Lew! What’s on your breadboard?
