I'm Back!

Lets talk about things I completely forgot about. Like this blog.

Its almost been two years since my last post, and much has changed since then. I've started and finished a few projects, while others have been pushed to the side due to lack of time. Lack of time is also why I haven't been updating this blog.

I logged on to blogger today after remembering that this thing exists, and apparently people have been reading it. This has inspired me to get back to writing, so lets get at it.

Let's start with project updates. 

I gave up on the ESQ-1 and sold it for parts.

I didn't have time to work on the guitar amps until recently. The SLO Clone is painfully close to working. I've learned a lot in the process of debugging it though. I also decided to completely re-cap the Fender Bassman. This is actually something that I have actually been working on recently (as in last week). Expect post about both of these projects in the near future.

Looking back on some of these posts is kind of a trip. My synthesizer setup looks very different these days. I've bought and sold a few pieces in the last two years. I also have a new found love for the Roland S-700 series of samplers. In addition to the S-770, I now own a S-760 and found a large sample library on eBay. Pianos, strings, and just about everything else sounds wonderful coming out of them. 

I've also started to work on a project not related to music too. I decided to learn how to program an Arduino. The first major Arduino project be designing and building swarming robots. I have a good idea about how to accomplish this and I'm working on a plan for the design, construction, and testing of the various components that will make up the robots. The name of the game is simplicity. The robots will follow two basic rules: stay near the pack and don't run into things. I ordered the first few components from Sparkfun yesterday and basic testing of a few design components will probably begin next week. Expect future posts about this project too.

That's all for now.

Ensoniq ESQ-1

I bought this off of eBay broken. Thought it would be a fun project. I still do, but it turns out it is more broken than I thought it was. It only plays the stock piano sound and the screen is messed up:

The ESQ-1 is a rad synth. It has digital oscillators and analog filters, three LFOs, a cool envelope generator, and a built in 8 track sequencer. You can actually program this thing to sound like a techno-type drum kit. It's sick. I just need to get it to work. I have a feeling, at the very least, I will have to get the EPROMs (the thing that stores the OS) reprogramed.

I tried a hard reset, grounding the battery (to reset the RAM), checking the voltages form the power supply,  and checking to make sure all the chips are properly seated. I need to go over everything and clean off any corrosion. If it still doesn't work I think I will have to send the EPROMS away to get re-programmed.

Since I took it apart, here are some pictures:

I'll probably get around to some more trouble shooting over the weekend.

New Things for the Blog

I've been thinking a little about the format of this blog and I have decided to set some kind of rough format. I'm hoping that this will force me to post regularly. Starting today I will have two new features.

On Mondays I will post what is basically an electronics 101 series of posts. This is mostly for me to review and remember stuff that I learned in college and promptly forgot, but also serve as a way for beginners to learn about simple circuits.

On Fridays I will have a post on skepticism/science, because reason rocks. I have already done two posts like this (here and here). Don't expect these to be super long essays, although some of them might be. It all depends on the amount of time I have. Some of the posts might be about things in the news, others might be about something cool I read that week and want to share. I will probably get stuff wrong too, but that's how we learn.

I enjoy feedback too, so feel free to post comments.

I'm hoping to start on a new project soon too, or at least finish some older ones.
