Squall Moan: Small Clone clone

squallmoan

Ahhh, where it all started.

I was jamming with a friend in his basement and he had a bunch of pedals, which I was noodling around with. None really stuck out to me until this little guy. If you want a sample of what it sounds like, there are plenty of test drives on YouTube. You may recognize its sound from Nirvana songs (only 90s kids will myeh myeh myeeehhh). read more

The Red Lama (Red Llama clone)

After making the worst fuzz pedal ever (that’s for another post) and Orange Ya Glad (which was fine, but didn’t add quite as much fuzz as I wanted and adds a weird buzz even when you’re not playing on some speakers), I just wanted a normal fuzz pedal. After doing a bit of reading, I found that the Red Llama overdrive pedal (by Way Huge) is a classic, and after watching a few YouTube demos, it seemed good (to be honest, people are crazy about the “different” sounds of various fuzz/distortion/overdrive that various antique/obscure transistors or configurations will give you, but they all sound pretty similar to me, and I suspect people think they’re hearing differences more often than there actually are).

Anyway, I wanted to tribute the original Red Llama circuit I was cloning, so I went for… read more

A spooOOOOoooky project!

bloodhead1

This is a fun one.

It’s also a testament to how nifty and easy it is to quickly whip up a project with Arduinos, provided you have enough of a “critical mass”, as I’ve called it before, of other stuff that you might end up needing. read more

A vegetarian experiment

Recently, my friends and I went to the NYC Maker Faire, and on the way back had a ~3 hour car ride. We got to talking about vegetarianism, saying how for the most part, despite most of us taking a devil’s advocate position at some point, we all agree that we don’t really have a defensible position for eating meat. Yet, we’re all fairly carnivorous. In fact, during the height of that conversation, we were going out of our way to get to a Five Guys burger place, so… the irony was not lost on us.

Anyway, we covered a lot of ground that I mostly won’t bring up here, because I’m sure it’s cliche and naive to anyone who is remotely involved in this. However, I thought there were a couple interesting points. read more

Getting back on the horse…er, Python

As of this writing, I just defended and I’m considering various options for what I’ll do next. That’s a whole other story, but the important part for this post is that, probably for whatever I do, I’ll be coding.

I’ve coded a decent amount in my life. I started with dinky web stuff wayyy back, then picked up a now-tattered and probably outdated “C++ for Dummies” book in highschool. I did small programs with that, as well as some silly things for crappy AVR projects I did. In college, I used mostly Java because that’s what the computer science classes I took asked for. Towards the end of college, though, I was working on my own research, and used C++ instead (why? I honestly don’t remember. Wait, I just did! My advisor had heard of some multiprocessor module for C++ that he wanted me to try, so that’s why I didn’t stick with Java). read more

Back to the blog and the NYC Maker Faire

Hey there, nonexistent reader! You may have (not)iced that I’ve been gone for a while. That’s because I just defended my PhD, and I was pretty balls to the wall busy for the last few months getting ready for that. I made a few posts here and there, but towards the very end I realized I really had no time for a blog that no one reads anyway. Maybe I’ll make a post about the whole before-and-after experience at some point.

Anyway, my friends and I just got back from a weekend trip to the NYC Maker Faire. Max has a friend who got us a few free tickets, which was sweet; they’re not inexpensive, something like 4500, which is genuinely not bad for a serious hobbyist, and was cutting decently thick steel. We saw a sweet firebreathing dragon built around an old pickup truck, that we all immediately thought came straight from Burning Man (and the people manning it reaaaally looked like burners (deep playa)). There was an ENORMOUS 3D printer, this style, but about 25′ tall: read more

A blast from the past: Canon control cards

A bit of background: our lab is kind of ancient. It’s also enormous; my advisor owns most of our hallway. The group was once very big (one of those 20-30 people powerhouses), but these days it’s fairly small (~6, plus a couple undergrads at any given time). However, we still have all the space from those massive days of yore, so a lot of the space is… well, let’s just say a lot of the lab space hasn’t been touched in a while. I mean, every room is still used, but there are definitely nooks and crannies that, if owned by a lab that had to be more economical with its space, wouldn’t remain as untouched as they are when I find them.

I poke around a lot. Often, actively searching for various equipment, but also just because I like to know where things are and explore. More than a few times, I’ve poked into some dusty cabinet and actually found fairly useful equipment that I’ve then used. A lot of physics/engineering equipment from 80s is still pretty useful today. read more

My first boat

IMG_6408

This is my first boat. It’s pretty silly, but was a lot of fun to make.

During the summer before my senior year of undergrad, I was staying at college and doing research on dilute gas simulations using Monte Carlo methods. My roommates and I had rented an apartment for the year (haha, holy hell…Worcester apartments are a special kind of grimy) and the lease started at the beginning of the summer. My roommates hadn’t moved in yet though, so I had the whole house to myself. read more

Low power Arduinos, part 1

pro_mini_led

As part of an ongoing project, I wanted to see how low I could get the power consumption of Arduinos to go. The reason is as follows. When getting back into Arduinos a few months ago, I wanted to try a telemetry project of some sort, collecting data remotely and sending it back. Ideally, the idea would be to collect data from different places and analyze the aggregate in some cool way, but that’s a story for another post.

The point I was going for, though, is that I wanted to put these Arduinos in places that wouldn’t have constant access to power, so that already means using a battery. Using a battery to power an Arduino isn’t a big deal (plenty of people do it for portable projects), but once you’re looking at long term powering without recharging, it’s a different story. read more
