gocco failure

printing stuff and doing stuff

i haven't put any effort into redesigning the blog, but i have done a bit of printing. this is my first foray into multiple colors. it's also my first use of the glow in the dark ink i picked up from blim a few weeks ago. i'm not sure what to make of the actual design as it's not quite an instant masterpiece, but from a technical perspective i think it's a good first crack.

made stuff/did stuff

the fruits of my make stuff/do stuff event. it's not a complete success as i'm not happy with the quality although i've pin pointed my mistake. the issue are all the little spots on the image. my mistake was converting my adobe illustrator file into a .jpg prior to printing. even though i used a relatively high resolution i introduced some small spots that are barely noticeable on the print out, but become a big deal on the gocco screen.

what i accomplished this weekend:
- i coated three screens for printing (not the gocco variety) yesterday and should be making some images later this week.
- i bought some uni-ball pins as i lost my other one. this may not sound exciting but they are way more fun to draw and write with than a normal ball point... trust me.
- i got some white gocco ink at blim, unfortunately they didn't have black, which is what i set out to find.
- i got a little water color set.

what i want to accomplish this week:
- redo my blog layout/graphics. i'm sick of this blogspot theme.
- make my new screens.
- find a good t-shirt supplier.
- kick it old skool... that's right, old skool

gocco a go-go

come make gocco prints with me on saturday, may 2nd! check out the facebook event

i love the smell of two-stroke in the morning

not a whole lot of making and doing these days, but today i finally got around to cleaning the exhaust on my puch sport mkII. an hour of jet black hands later and it's 5 mph (8 km/h to my metric friends) faster... sweet. i also took apart the carburetor, but it looked spick and span, so there was no work required. now to get it registered so i can get back to the mopedery.

success!

problem solved. it turns out i didn't solder one of the output wires in the correct spot. unfortunately it was going to be a really tight fit to get it all in the altoids box, plus we didn't have the proper tools to modify the box. so, we ended up finding it a temporary home in an old ipod box. it'll have to find something better, but for now it does the job... making stuff louder.

cmoy pocket amp

so, my buddy cameron wanted to make a pocket amplifier to use with his ipod (you can never rock too loud... unless you blow an ear drum, which is too loud). he found this well done tutorial over at tangent soft. we got the supplies and started assembling on my bread board. the problem is i haven't touched a real electronics project since university. this was one of several factors that led to a series of problems. here they are in chronological order:

1. one of the capacitors blew up when i put it in backwards
2. the volume knob (potentiometer) was a linear pot and was only for one channel.
3. the voltage splitter went all crazy when the headphones were plugged in (i.e it sounded terrible)
4. once we soldered it up the right channel wasn't working properly.

the capacitor fix was easy: don't be an idiot. the volume knob took some more work as i had to trek all over town trying to find one. when i finally did find one it was super old school with no schematic online, so i had to sort out what pin was what myself. that is probably easier for someone who knows what they are doing. cameron solved the voltage problem. apparently he has very low impedance headphones and there was a significant offset current (i.e. the amplifier needs a certain voltage range to operate and the headphones where mucking it up). so, a couple of electrolytic capacitors later the problem was fixed. we haven't fixed #4 yet, although i should have some time today. i'll keep you posted. here are some pictures of the progress:


it was one of those black capacitors that blew it's top.
