On the Breadboard

May 30, 2016

Maybe this will be a recurring series. It should be possible if I’m actually Making Things.

Bazz Fuss

Information about the Bazz Fuss can be found here.

A few years ago I tried out the Bazz Fuss and was very disappointed. Being careful with transistor and resistor choice seems to be much more crucial than People on the Internet imply.

I actually fried one transistor by using a variable resistor that was allowed to vary down to zero. Was quite amusing to turn it down, then up again, only to find the tone was drastically different. Somewhere in the middle of this process I made an instagram video. Bazz Fuss fried video.

The “best” version I created consisted of a clean boost followed by a standard BF with high gain, then a tone stack, then a BF with lower gain and emitter degeneration added. This allowed bizarre octave-up effects with tone high and big muff-esque tones when low.

Double Bazz Fuss with Tone video.

Chance that I’m develop this further? It *was* pretty high before I built the next Thing. Now, slightly less.

Harmonic Percolator

The Interfax Harmonic Percolator is an legendary (or at least notorious) fuzzbox mostly associated nowadays with the music of Steve Albini. Albini has several youtube videos on the subject. There’s some info here.

Tried out a Harmonic Jerkulator, an all silicon Percolator clone developed by Tim Escobedo. Details available here. It sounds amazing. It doesn’t sound Albini, but neither do “faithful” clones or any other variant I’ve heard, so whatever. Sounds like a germanium fuzz-face to me except despite being boomier it never gets muddy enough to where you can’t hear all the notes.

Chance that I’ll develop further? 100% chance I’ll youtube it, 50% I’ll box it up, 20% I’ll try and market it.

Ruby

The Ruby amplifier, from runoffgroove.com.

Built this LM386-based 0.25W amplifier. It sounds suspiciously good. Even when plugged into my upcycled computer subwoofer. I’m definitely gonna box this up. This is an extremely high-margin Thing if it were ever to be Etsy’d.

100% chance it’ll get boxed up. I’ve never sold on Etsy before so … if I ever decide to this’ll probably be the first thing I do.

Anyway, those are the three ideas I’ve been monkeying around with over the past week.

Wood

November 5, 2014

So I built a guitar amp sometime in the past year, but it’s just a naked chassis and I’ve been meaning to make a head cabinet for it.

IMG_1065.JPG

When my parents built their house they used reclaimed hart pine flooring that my dad recovered from an old house on my grandpa’s property. They had some left over and it’s been sitting in a pile in my dad’s shed since 2001 or so.

This is wood from trees that were cut about 100 years ago, from the centers of old trees, from the first trees to ever be cut from these forests, or so I’ve been told. It’s still just pine, right?

I took four boards to try and use for my amp head cabinet.

IMG_1066.JPG

They’re covered in ancient dirt and dust and paint too. I’m afraid to sand the paint off because of lead, so I got a crappy block plane to try and plane it off.

IMG_1067.JPG

It took a lot more effort than I expected just for that little bit and to be honest I might as well be planing with a chisel. So I might have to take it outside and sand off the paint with the vacuum running before I plane it. The wood is really hard and the plane keeps getting stuck. This one is hard to adjust–you have to get it where you want it then tighten a wheel but if it’s not in the right spot you can’t nudge it any, you have to start over.

It might work better if I sharpened it, so I probably need a way to sharpen it. I figure my actual next task is to make rough cuts to the right size before I waste any more time with the plane.

Whale Boost production
Two chassis are tooled, labelled and finished. Circuit board design needs to be reviewed, then boards populated, then everything assembled. I’m estimating two hours for each step. I’m wanting to have both board designs reviewed by friday.

Son of Screamer variantDo not work on this until Whale Boost is done.

Arduino Synth ModuleDo not work on this until Whale Boost is done.

Baby Whale Amp
I want to implement a tone bypass, to replace the useless preamp plate starve. I also need to design and construct cabinetry for the amp. I’m looking at an hour of planning the bypass, then I need to source a DPDT switch. And install it. Planning this should take 30 minutes. Installing up to an hour. I hope I have a suitable switch laying around, otherwise sourcing will be annoying. I want to have the switch in hand by Saturday.

For cabinetry I need to make measurements, come up with a design, then build it and finish the wood. I’m looking at an hour of measurements, two hours of designing, and then god knows how long with the rest since I’m not a woodworker. I’m going to make those measurements by Sunday.

School Project
I’m on a team with three others on a project. We have to select a project by Monday.

Exciting post with multimedia for all of these things coming very soon.

Early April Update: WordPress glitchy bullshit; RSS; school–drugs–psychiatry; dogecoin; DIY update

April 1, 2014

WordPress Reader Sucks: Apparently the reason I’m not showing up in some peoples’ readers is that when I changed my name, it left you all subscribed to my OLD name and not following my new name. Yes, EVEN THOUGH it says you are following me in your reader, you have to click unfollow and then click follow again. Basically, this is the deal: never ever change your wordpress name. Not only will you lose all your followers, it will LOOK like you didn’t, and none of your followers will think there is any problem.

RSS: Of course, if everyone just followed via RSS instead of via WP’s built-in Reader, this would not be an issue at all. The fact that RSS is a dying technology angers me to no end. My suggestion is to subscribe to everyone ever on RSS. Get a deskop-based RSS reader or if you want, a cloud-based one. With Google Reader having bit the dust IDK what the best cloud-based ones are anymore.

Mental Health: Life is basically terrible. I had to confront my teacher today to give her an explanation about my absenses and late assignments because they became too great. She was sympathetic and we bonded over our hatred of the Office of Disability Services personnel. Now, of course, I have to complete three assignments in the next two or three hours, but the actual source of the actual paralyzing anxiety is actually gone.

Drugs, Typography: Today I took half a NuVigil at 4:30AM and a whole Klonopin at 7:30AM. Class was at 8:00AM. To the chagrin of most of the other students, I spoke more in class today than usual. I blame drugs. Everyone else was basically asleep while I interrogated the professor about different style-guide’s recommendations for dash typography. A reader may have noticed that I am a big fan of using dashes instead of parenthesis. My professor recommended using a dash in that way about once a page or so. Dash usage is a habit that can get out of hand really quickly.

About class. Did I mention I missed a full week last week? I couldn’t do anything! I’m considering upping my Vibryyd dose but I have an appointment in a week, so I might as well wait until then to discuss it with the pro. Thank the gods for the “emergency” drugs.

Dogecoin and Cryptocurrency Day-trading: I currently hold 23,000 Dogecoin, which has been sitting at an ask price of 121 Satoshi for a few days. The price reached 120 the other day but never touched 121 and I’m very disappointed. It’s now trading at 111 and 110, so I think I’m going to play market maker for a while today before placing another high ask, maybe at 118 or so. I bought at 114, and the price is almost 100% guaranteed to reach 115 eventually, so I’m not worried. I am not currently doing any automated trading.

DIY projects:

  • Single-transistor-dirtbox: I populated and drilled the board I etched. There is too much gain and the transistor saturates with almost any input at all. I replaced the 1M miller resistor with a 500K potentiometer. At 500K it sounds close to what I envisioned, but when reduced the miller capacitance dominates and an odd effect occurs: the lower the gain the more high frequencies are rolled off. I’m thinking that I like the actual idea of this kind of effect, but the pedal overall is now too dark. I’m thinking about adding a treble-boost cap in parallel with the top resistor above the diodes, and also reducing or eliminating the capacitor in parallel with the diodes. That way the pedal will still have idiosyncratic controls that inspire through their simplicity, but will also be usable. Also considering changing those resistor values to add more distortion anyway.
  • Champ-inspired tube amp: I love it, it’s great, the few glitch aspects of it are relatively minor. I still want to paint it, which will be a pain since everything is already bolted on. I’m thinking about replacing the epoxy’d in standoffs with screwed in standoffs, for no real reason other than the epoxy keeps breaking. Possible additions include adding a power brake–if I do this it will be done shittily, with just some wirewound resistors. I also need to redo the speaker jack wiring so that the output transformer is less likely to be damaged in the case of a cable malfunction. Also I want to build a cabinet. My dad has some leftover hart pine from building floors in his house like ten years ago that have just been sitting around for eons. I don’t know how to work wood. I think I can figure out the joinery–basically I will just hack stuff together and if it doesn’t work, use metal brackets instead. It’s the sanding and finishing that I’ve done the least work with. How exactly does one finish hart pine? I suppose it would be a shame to paint it or cover it in tolex, so I’ll just leave it looking like some expensive antique furniture, lol. Is staining ever used on pine? If so I might be able to do something cool. I’m thinking about naming this amp the “Baby Whale”, by the way.
  • Found Amp: I found a $60 Ibanez practice amp by the side of the road. It turns on but does nothing but makes a loud buzzing sound–this is probably because the power cable is missing the “earth” pin. Someday I’ll fix it, even though it almost certainly sounds worse than my Roland Microcube (which is of similar wattage and speaker, but is a modeling amp) or either of my Peavey Combos (which is of a similar solid-state design, but are much higher wattage and have better speakers).
  • Found Chassis: I also found a tubedepot.com blank amp chassis. It’s about four times the size of the one I used for the Baby Whale. I supposed some day I’ll build an amp into it. Maybe something Plexi inspired? I’m honestly not sure that I would ever want an amp that uses a quad of power tubes. I love the 6V6 in the Baby Whale, so maybe I would go for a dual 6V6 or dual 6L6 design. If I gigged in a room big enough to warrant a quad, I’d be mic’d up anyway … right?
  • Antique Radio Restoration: I have made no progress on this. One thing I need to do is purchase a set of “all american five” miniature vacuum tubes from ebay. Apparently a full set of five can be had for ten to twenty USD. One thing I learned about the five-tube design is that the use of these particular tubes is what allows the lack of a power transformer. The tube filaments, when placed in series, demand a total of precisely 110VAC. Guitar amps usually use a power transformer that drives all of the tubes at 6.3VAC in parallel. In this radio all five of them are stacked so that the total voltage is what matters, and it has been designed so that the total is the same as the standard line voltage. IDK why this is considered to save money, however, since there are two isolation transformers present that I would omit if designing this radio myself today. Perhaps high-voltage quality capacitors were not available or reliable in the 40s. This radio might also need woodworking.

So basically I have made tiny amounts of progress in a wide variety of things. It could be worse. Which of these topics would you like an in-depth post about?

(I.e. What do you want to see pictures of? Getting my recording studio running again would be yet another project, so sounds must have to wait.)

PCB Etching and Guitar Rewiring

March 21, 2014

Supposedly this is everything I need to etch a PCB.

20140321-222208.jpg

Also I’m rewiring a guitar. I already “dewired” it, lol. When my friend Travis moved he let me have it. That was almost a year ago I’m just getting around to fixing it.

20140321-222506.jpg

I might need to sand some of that flaky looking wood? IDK.

Not sure if there’s a way to get the rust off some of this hardware other than by buying new. Also three wood screws are missing.

20140321-222633.jpg

It looks like the rear cavity was shielded with conductive paint but much of it has worn off. Redoing that might be unnecessary though. If I did I would use copper tape instead.
