Hammond Case Size Chart

I’ve been poking around at effects pedal enclosures again and thought it would be nice to have a chart to compare the actual sizes of the common Hammond-type 1590 series project boxes. So I made up a Hammond 1590-series Comparison Chart [PDF].

Hammond 1590 Comparison Chart

I used dimensions from Hammond and from a third-party lookalike (the boxes sold by Mammoth Electronics, in this case), unscientifically rounding dimensions to what seemed to make sense and then approximating those in Inkscape. The stated dimensions should be close enough, possibly 0.1″ off but usually less. The one exception is the height of the 1590LB boxes, which can differ almost 0.25″ from Hammond to others – I went with the larger 1.3″ dimension on that one. The actual size when printed should be close enough to actual size to get a good feel of how big it they are in addition to relative sizes.

The PDF will probably print more nicely than the PNG file, but both are full 8.5″x1″ letter page size – for dimensions to be accurate you’ll need to print at actual size, not scaled down to fit in margins at all.

Ruby Amp Build

Ruby Amp: Finished Cab without GrillOne of the things I have been wanting to do almost since I got an electric guitar – over ten years ago – is to build some of my own effects pedals. I decided earlier this summer (2012) that I am actually going to do that, by golly, and not just true bypass mods and control switchboxes like I’ve done in the past. Real analog effects circuits this time.

Then I realized that I wanted a way to test things at my electronics bench without lugging my mega-ton 112 combo up and down two flights of stairs and decided I needed a practice amp first. I could buy one of those, I guess, but I want to build stuff – why not that, too? And I managed to do it for practically free. Continue reading

Emergency Garage Release

We had a power outage a while ago, in the middle of which someone needed to get out of the garage and… couldn’t. The door that needed to be opened was, naturally, the one that wedges itself in slightly when it shuts, so it jams the electric opener’s emergency release.

Further investigation revealed that a good hard judo-yank will release it (with a bang), but not everyone can do that. So I made a release helper – because almost anyone can step on a lever. The pictures pretty much say it all – just hook the custom specially calibrated clothesline to the release pull and step on the board.

This is it.


Drilling Holes Without Spewing Sawdust

This is one way to drill a hole without getting too much sawdust all over the place, even using a spade bit.

Fencing your woodchips with masking tape.

Fencing your woodchips with masking tape.

I normally reserve creating sawdust and messy things like that for the Shop For Big And/Or Messy Things, far away from my office/computers/electronics bench. However, the Shop For Big And/Or Messy Things is really cold in the winter and I was feeling wimpy.

Consumer Fake Out: Your Nightlights Are Lying To You

This past week I picked up a couple of cheap LED nightlights at Marden’s ($1.99 for a two-pack) and had to take them apart, of course, as I am a self-respecting geek, and because I was at one time mildy obsessed with running LEDs off line power. I guess that hasn’t quite worn off.

This all has led me to two conclusions:

  1. American consumers are suckers
  2. Chinese are either idiotic electrical engineers or brilliant social engineers, or both

Actually, both of those are not entirely deserved, nor totally fair, but read on for the full tear-down. Continue reading

The Finer Points of Podcasts with RSSOwl

Since I’ve been using Google Reader for my feed-reading needs the last few months, I have been spoiled by Reader’s nonchalant handling of just about any feed I throw into it. It’s also available anywhere the internet is, which is very convenient for keeping breaks at work useful and non-boring. (The breaks that don’t involve food, anyway.) I also like the fact that “just about any feed” includes podcasts, so I have a convenient way to keep track of those at work as well.

Unfortunately, podcasts with Reader rely on frequent browser use – something I’m trying to limit – and a 6′ headphone tether to the computer. There is also no good way for Reader to sync with a portable device so podcasts can be heard sans computer with direct net connection.

My solution is to use RSSOwl with a couple custom filters and a custom batch script to sync to a removable USB device (my phone). Here’s how to do the magic and make your life easier.

Repairing A Mic Stand Adjustment Bolt Thingy

There’s got to be a better term for those little knobs that you tighten (or loosen) to adjust mic stands. And this is actually about making new ones for replacements. Anyway. A couple of these knobs stripped or went missing and here’s how I put wooden knobs on standard (cheap) hardware store bolts to replace them. Continue reading

On Vacuum-Pumping Water Out Of Large Things Filled With Water

If you, like I, have a boat full of water (and sticks, and leaves, and dirt, and other crud I was scrubbing out of it), then you also may not want to just tip it up and let all that trickle through the hull drain at a slow an increasingly clogging rate. Never mind the residue left inside the hull.

My trusty garden-hose siphon was not going to cut it this time, either. I could have used a bailer… but that’s just not as much fun. And no, thank you, I didn’t want to use my trusty Rainbow vacuum cleaner to pump a gallon at a time again (an often dicey and tedious prospect). And more splashy-messy. So I used good ol’ R2VAC2 as a suction pump/super-siphon starter.

When The First Idea Doesn’t Work…

When I put the headlight on the snowblower and then proudly wrote a post detailing my amazing methods and proclaiming “it works”, well, I should have waited because it doesn’t. It held up the light until I actually started the tractor. Then it slowly tilted because the clamp wasn’t tight enough and I spent that hour of snowblowing in between correcting the light angle.

In Which We Upgrade An Antenna

As I’m sure you all know and undoubtedly agree, the bigger the antenna the better it works. This is true of wide-band receive aerials, anyway, at least up to full wavelength or so (I think – my antenna theory is a little rusty these days). Most people don’t like ten-foot antennae on their car, though, so most AM/FM receive antennas are quite a bit shorter. I, however, being a fan of good radio reception and also of big antennae, decided it was time to upgrade the car again. Continue reading
