Check out my new(er) cd robot project here. I grabbed an old scsi changer machine from ebay and have been working on adding serial connectivity to it. If it works, it will be a much simpler route!
One of my “always in my head” projects is a CD changing machine. I have seen the myriad of other projects out there, and this always captivates me, in that it is just out of reach, but it seems to be a fairly simple concept. I have been thinking and sketching on this one for SUCH a long time that I have decided to post it before it is fully polished up.
The basic premise is I have an arm that swings up and down mounted on a platform that rotates 180 degrees. Both of those are positioned by hobby servos. On the tip of the arm there is two vacuum aided suction cups and some hdpe tubing.
So it has been over 2 years since I started my project motorcycle. It’s a 71 honda cl350. I bought it in boxes and slowly put it together with the help of a friend over the last 2 years.
Last weekend I actually got to go out and ride the damn thing! I have to admit it was a little frightening, because it’s been 2.5 years since I last rode a bike, and even that was only for a 3 day licensing course. All in all it rode well, and most of the problems were with my shifting ability, or my riding ability.
The one issue that I did have was the bike continues to rev high after putting the clutch in. The only way I can get the revs to come down (at a stop sign for instance) is to downshift and brake all the way down into 1st gear. If I get it down to 1-2k then it will generally stay there.
So this post is a big shout out to Sparkfun Electronics. Not only are they an interesting shop that has tons of stuff I would love to tinker with, but they give really good customer service as well!
Recently I ordered a bunch of stuff from them, including a few temperature sensors, thermistors, and an rf transmitter/receiver pair. I ordered, they shipped, and then fedex delivered it to my front porch where it was promptly stolen. I was super bummed to come home and find nothing. I had the whole afternoon off and I was planning on putting in some serious geek time in the basement. Needless to say, fedex dropped the ball by leaving it at my front door (on a busy street, less that 3 feet away from the sidewalk) and some jerk ended up with an envelope full of stuff they probably promptly threw away.
I left a message on Sparkfun’s site and filed a claim with fedex. Paul Robinson from sparkfun got back to me fairly quickly (he even tried to call(!), but I wasn’t around) and they shipped out a replacement order.
I was initially really down about not having anything to play with over the weekend, but this is honestly the best-case-scenario considering it wasn’t sparkfun’s fault that the package was stolen from my porch.
So thanks, sparkfun. I appreciate it, and keep up the good work!
Two more things for icing on the cake, my package arrived today(YES!), and I asked Paul a question about hackerspaces in boulder during our emails about the stolen package. He said he didn’t know of any but would pass it on to someone who would. Yesterday I received an email from Nathan Seidle, the CEO. I love the fact that their customer service provides service, I love the fact that they wanted to make it right, and I love the fact that their ceo took time to answer my question.
