Goings On

Sunday, May 31st, 2009

As much as this blog would indicated due to the lack of posts lately, I actually haven’t been slacking (too much) in the blinky flashy world. I’m still waiting on the Ren2DMX boards and the pixel boards, so that will be some stuff to assemble once it arrives. In the mean time, I did some more tests on the LEDs that I will be using in the pixels. I tried using 6 of each color this time to give a better representation of what they would look like in the pixels. So far they seem like they will be bright enough so I’ll keep my fingers crossed. I ran the LEDs for several hours because In talking with Tim Y. at LUO, some have the potential to work at first and then fail. Not looking forward to debugging and desoldering LEDs, I wanted to get some run time on them first. I tried the LEDs in the containers I’m hoping to use for the show, they look OK, but the arrangement of the LEDs on the breadboard isn’t the same as the pixel, so there were hot spots of the different colors. I’ll wait until I get a pixel assembled before posting pics.

The 300′ of 12/3 Cable I ordered off eBay came this week. It arrived in great shape, but to be certain that I got 300′ I ran it across the warehouse floor to measure it. This caused it to get all dirty, oh well. It’ll get clean again once it’s outside in the rain. Seems like good cable. I’m slightly worried that it isn’t SO, but rather, general purpose, but I knew that when I bought it, and it is only going to be outside for 2 months, so hopefully it’ll be ok. I was able to fit all 300′ on an old hose reel which will be nice for storing the cords once I make them.

I also started work on my temporary sub-panel. I’ve got the breaker panel and all of the receptacle boxes mounted. I want to get the SSRs mounted before I begin wiring, but I can’t really do that while my daughter is sleeping so it severely limits my opportunities for mounting them. I also got the input cord attached and ready to go. The 6/4 SOOW cable is NICE cable, but it should be at $3 a foot. Good thing I didn’t need 300′ of that!

Pixel News

Sunday, May 24th, 2009

Heard back from JEC tonight, he’s expecting the boards this coming week, so hopefully they will be in my hands by next week. I’ll try not to get too excited until they are here, but it’s kinda hard… Time to dust of the soldering iron!

PICs are here… Waiting for boards!

Saturday, May 23rd, 2009

The PICs that were on backorder from Mouser for the Pixels arrived today. Now I have everything I need to make me some Pixels… everything except the PCBs! Think I might email JEC tonight to see if he has an updated ETA.

Not much going on

Friday, May 22nd, 2009

Haven’t made much progress on the blinky flashy front. I’ve been playing with sequencing a bit more, but am still hesitant to dive right in as I haven’t quite finalized the layout of the display yet. I found some 12/3 outdoor wire on eBay yesterday which appears to be the military equivalent of SO wire. I got 300 feet for .46/foot shipped. Seemed like a good deal considering the local hardware wanted 1.15/foot + tax. The plan is to use this to feed the controllers from the subpanel. The 12 gauge is overkill for the 15 amps I am currently planning on pulling, but if I ever decided to move a board up to 20 amps (which I may as I currently have one whose calculated load is 14A), I will either need to run another complete cord or use heavier cord, which is the reason I went ahead and got the 12 gauge.

Actually I just went and looked at the chart again, and the 12 AWG will only handle 20A up to 50′. Fortunately the controller in question won’t be that far away, but still good to know. I also see that the 12 AWG is only good up to 10A at 100′, which one of the controllers will be, kind of disappointing, but that controller isn’t near 10A yet, so we won’t worry about it just now. I’m glad I got the 12/3 after all.

The sub-panel is under way. My dad is going to use his plasma cutter to put a hole in it for the wires to come out. After talking it over, he talked me into letting the panel lay on its back in order to keep it more stable. We are going to build some sort of frame on it to allow it to be moved around easily because once all the pieces are in it, it is going to have some weight to it.

I’ve also begun looking for solutions to locking the controllers and sub-panel in some fashion. I’m leaning towards cementing an eye bolt at ground level so that I can mow over it during the summer, or mounting some sort of hasp, so that the hasp covers the screws when it’s locked to the house and locking the stuff to that.

Light Up Ohio 2009

Sunday, May 17th, 2009

I’ve been to conventions and stuff before, mostly for the grocery store, but I must say this Light Up Ohio was one of the most enjoyable things I’ve done in a long time. I’m sure it was because it had everything to do with my new hobby (eh… habit) and the entire day I was surrounded with knowledgeable people who have the same habit.

All of the presentations were very interesting and I learned something from each one of them. The food was EXCELLENT. We had Gregg Jones’ pulled pork and it was fabulous. I got a cool shirt and bought a hat (forgot to get pictures to post), but the best part for me was the prizes. I NEVER win anything, but I actually won two pretty cool things. I won my choice of a lighted wireframe from www.christmas-leds.com. I chose the cool white LED snowflake. It was what stood out the most to me, but now I think I’ll need to buy some more! I also won a penguin blow mold. I’ve never really been into blow molds and this is my first, but after seeing it lit and looking at it more, its starting to grow on me. It doesn’t hurt that April loves penguins, so she was excited about it.

I took away many ideas, namely the portable hole and JUMP pole that Walter and Jackie presented. I am going to try my darndest to have a mega tree in 2010 based on some of their ideas. (Oh darn, that means more controllers and lights!!!). I also got an idea from Dave Jones about an FM transmitter using an Arduino that I’m tempted to try. I still really like the EDM units, but it is tempting to roll my own and from what I hear the quality isn’t bad.

I mentioned in another post a purchase that I arranged to pick up at LUO. I bought a electrical enclosure for $20. The enclosure is very nice (and heavy!). It is 2′ x 2′ x 8″, and should be plenty of room for both the breaker panel and the outlets. The plan is to put a single 3 or 4″ hole in the bottom to run cords through and the rest will stay as is. I’m also going to paint it gray so it doesn’t stand out so bad. What’s nice is it has a mounting plate in side that everything can be mounted to so I’m not perforating the outside to get things mounted well. It isn’t technically rated for outside, but it has nice seals on it to keep dust and moisture out, so I think it will do just fine. I’m probably going to put some sort of rain cap over the top to keep the water from running into the door, even though I highly doubt it would get it, I’d rather be safe than sorry since it isn’t “rated for outdoors”. Thank you Gary for hooking me up with that! I’m hoping to find a cheap 2 wheel dolly to mount it to to make it easier to move around. If I can find one cheaper than making a treated lumber stand, I will just weld some supports to it and use the dolly as the stand. Otherwise I will have to come up with some sort of stand that can be easily moved. By the time the equipment is mounted and the stand is added, it’s going to have quite a bit of weight to it as it already isn’t very light.

All in all, LUO was a great experience and I hope to be in attendance next year.

LightShow Pro: First Impressions

Monday, May 11th, 2009

Over at DLA, they’ve been talking about some new sequencing software called LightShow Pro. Although one of the reasons I went DIY was because I refused to pay for sequencing software, namely LOR, I decided to give the demo/release candidate of this software a try. I’m going to give them the benefit of the doubt for several reasons: 1) It’s still a release candidate, and therefore not finished. 2) I haven’t spent much time using the software, nor have I seen many tutorials on using it. 3) The laptop I’m running it on isn’t the fastest thing in the world, but at the same time it keeps up.

Anyhow, first impressions: I’m going to stick with Vixen. I like to judge software on how usable it is without a manual. I like to think I can maneuver myself through software pretty darn well (I’m no novice is what I’m trying to say), however LSP seems to have a bit of a learning curve to it. I created a test sequence and added a DMX controller, and really didn’t get too much further than that. The software seemed to bog down and I couldn’t get any output to the lights at all. I couldn’t immediately locate a “test channel” feature and was having trouble getting the effects to draw, and ultimately gave up.

I think the software has a lot of potential, but some good tutorial videos and documentation will go a long way to making it easier. The preview drawing seems infinitely nicer than Vixen’s, and some of the effect generators like the chase (which I couldn’t really get to work) sound nice also. I like the “variable period length” as you can define your effect, and then drag it to get it to line right up with the exact point in the song you want it to. Having said that, I also think Vixen has equal potential if some documentation for the various plugins/addins were created. I’m hoping to do some of this myself, but there’s only so many hours in the day.

In other news, I think I made a deal last night on Planet Christmas that will make my temporary sub-panel much easier (and cheaper) to create. I’m supposed to pick up the enclosure at Light Up Ohio on Saturday, so assuming all works out, I’ll give more details and pics once it is here in my basement. I don’t particularly want to jinx the deal by discussing the details now (no it really isn’t that big of a deal, I just don’t want to get into it right now).

Arches: Take Two

Friday, May 8th, 2009

Last night I put my newly laid Leaping Arch plans into action. I made several changes, some of which I mentioned in the previous post, but I will recap them here.

The Arches are made from 10′ sections of 3/4″ PVC electrical conduit (as opposed to the 1/2″ I was going to use). The main reason behind moving up one size is so that I could insert a piece of 1/2″ metal conduit inside the PVC conduit. When attempting to wrap the test arch on the 1/2″ conduit, it became quite flexible and unmanageable once a few strings of lights were on it. It was difficult to twist, and towards the end I was actually rotating the lights rather than the conduit. It didn’t make for an enjoyable experience. With the 3/4″ conduit that has a 10′ length of 1/2″ metal conduit, the entire unit becomes quite rigid and manageable.

I also decided to use 7 channels per arch rather than 6. 6 would have been nice because 4 arches would have only used one controller, but the more I watched arch videos the more I liked having the odd number of channels. With 7 channels, and 4″ of blank space to keep the lights out of the grass and snow at each end, each channel ended up being 16″. Wrapping a 100 count string (24.7′ according to the box) tightly, but not too tightly, worked out to almost exactly 16″.

We (being the wife and I) decided to scrap the two color arch idea and use the channels to have more arches. I think the “awe per channel” (yes I made that up) factor is much higher with more arches vs. more colors.

I wasn’t in the mood to sit on the floor and wrap arches last night, so I set up an arch wrapping rig in front of the TV here in the basement. The rig consisted of a small ladder and a chair. The ladder held one end of the arch while the chair held the other. To each, I attached a 1 1/4″ PVC coupler with wire ties. The coupler received the 3/4″ conduit and kept it in place as it was rotated to wrap the lights. Once I got into a rhythm, I was able to do a channel about every 10 minutes.

One thing that helped speed up the process is that I elected not to extend the plugs by cutting off the end after each channel was wrapped and soldering in a piece of SPT2 to extend the plug to the end of the arch. The main deciding factor in doing this was that everyone was in bed, and the heat gun that I have for shrinking shrink tube is rather noisy. In addition it allowed me to actually finish the arch last night, whereas if I was constantly stopping to cut off ends and solder them back on, I probably wouldn’t have gotten done. Another plus to doing it this way, is that if a string goes bad, it should be easier to replace. The plan right now is to make up extension cords with the SPT2 and just wire tie them to the underside of the arch where they won’t be seen very much.

One modification that I needed to make to the system, was to take a plastic lid from a deli container and cut a hole in it to slip over the end of the conduit. This was to keep the lights closest to the ladder (the first channel I wrapped) from catching on it and either holding up progress or damaging the lights.

I would have actually gotten done in time to post this last night except as I was completing like the 2nd or 3rd strand, I got to the end and the wire going from the plug to the first socket came out of the socket. I had to pull out the contact and try and get the wire reattached. It didn’t want to crimp, so I got out the soldering gun and tried to solder it. As you can see from the picture, it wasn’t the most attractive joint, but it seemed to get the job done. Had I been here at my work area, I think I could have done a better job, but on the spot repairs in front of the TV, while trying to keep solder off the rug, doesn’t lend themselves to nice looking joints. I don’t think the wire came out because I was wrapping them too tightly. I think it was just that way from the factory.

Tonight I’ve been playing around with sequencing. I created a new Vixen sequence with actual music (Standing In Motion by Yanni) and have been messing with different arch effects in time to the song. If anything it has reinforced the fact that it is going to take FOREVER to sequence the songs and I’d better be finalizing everything soon and start sequencing at least by the end of June. I also need to play to see what types of effects look best and which don’t.

I’ll try to get some video of the two arches in action (I still have the 6 channel arch assembled) if I have a chance tomorrow.

A Boost to my excitment from the Blinky Gods

Tuesday, May 5th, 2009

I finished labeling the rest of the Ren24s last night so as far as I’m concerned all 96 channels of Ren24 are now D-O-N-E! I’ve been kind of bummed lately though because I didn’t have my Ren2DMX boards or my pixels, shouldn’t really bum someone out, but for some reason it was… I think it was just the not knowing part. Tonight Frank e-mailed me to let me know the Ren2DMX boards will be shipping out tomorrow! Yea Frank! I figured he would come through, but still, not having heard from him I was starting to doubt. Anyhow, that has renewed a bit of a spark in me, and I’m ready to move on.

I need to get cracking on the arches and I’ve been giving them some thought. I think that I’m going to scrap the blue and stick with just white to give back 12 channels. I’m going to use the extra channels in addition to 4 I think I can steal from another controller to give the arches 7 channels instead of 6. Everyone kept saying they look better with a single channel at the top and the more videos I watch, the more I think they’re right. With 28 channels and 7 per arch, that gives me 4 arches rather than the planned 2 which I think will look better than just the two. Tomorrow I’m going to snag a piece of 3/4″ pvc conduit and a piece of 1/2″ metal conduit to go inside while wrapping to keep it more rigid. I’m hoping the extra diameter in the 3/4″ will help fit the extra channel in better as I just got 6 to fit pretty well on 1/2″.

I’m not sure yet what I’m going to do with the 12 sets of blue that will now be surplus if I go with this plan, but I’m sure I can some up with something!

Labels Have Arrived

Friday, May 1st, 2009

The Avery Permanent Labels that I ordered off eBay came yesterday. I would have posted about them yesterday, but someone forgot to renew the inolleb.com domain (see previous post). I ran them through our Brother color laser printer at work, and they turned out pretty good. The colors appear bright and the labels have a plasticy feel. The adhesive appears to be stronger too. I took one of the labels and put it on a spare case that I had and then poured water on it. The printing didn’t run, fade, or do anything, and the label remained stuck to the case. I made channel markers that are supposed to hang off the wires like little flags. I found it is pretty hard to get the two ends matched up perfectly, so I might try to find another way to label the cords in the future. I put a label on the inside of the case because when I work on them, I like to take the door off, and then I don’t know which controller I have.

Oops

Friday, May 1st, 2009

Apparently someone (me) forgot to renew the domain registration for inolleb.com. My apologies for those of you that tried to view the site and were instead redirected to a site full of ads for porn sites and what not. I renewed the domain for 5 years, so you shouldn’t be subjected to such a thing for at least 5 more years.
