Firefly 2016


This was my first net-negative experience at a burn or con. The things I learned will have positive value in the future, so eventually I can look back and say this weekend was worth it, but I don't know how long that will take. I've finished burning a lot of bridges and made some new friends. Firefly is still the best regional burn I've been to, despite its flaws, and I'll probably return if they let me.

The Good

I got to spend some part of a couple of days camping with some of the people whose company I enjoy most. This is a welcome reprieve from what has been mostly solitude on the west coast. There were friendly conversations as well as good hugs and cuddles. Due to some things mentioned in sections below, there's a good chance I'll get to spend more time with those people fwen I return to Firefly.

Consent violation accusation

I've just heard third-hand, through a grapevine comprised of at-least-mostly bay area people, that "someone has complained ... that you were insufficiently respectful of sexual consent boundaries", and this is resulting in me not being welcome in some spaces at an event.

I don't know who is accusing me. I don't know what they are saying I did. I don't know when or where it happened.

I don't know how much of a game of telephone is going on here. Is this another case of someone labeling me "rapist" based solely on conversations about consent, as happened a couple of times in Boston, and then someone else taking that label at face value?

I've been sexually intimate with four people on the west coast since moving here. Two of them I am still dating and fucking (intermittently), and both seem quite happy to seek out my company. The third asked for a demo of a fucking machine at Dark Odyssey Surrender, and seemed to enjoy the experience and leave happy; I don't know her name and have no idea how to contact her to apologize. The fourth seemed the most likely source of the rumor, since she ended our sexual relationship, so I sent her an attempt at an apology. She coaxed the story from me and explicitly denied it.

If this accusation is following me from my road trip, or Chicago, or Boston, or Atlanta, then I am at a complete loss for how to proceed.

Sparr's weekend at Frolicon 2016

This is the second half of my post-con writing, following a con report style post that's not specific to my experience.

I went to Frolicon this year, after skipping the event last year for logistical reasons, and not otherwise having been to Atlanta for a couple of years. It was a fun weekend, quite full of social and play time with friends and acquaintances, old and new.

Frolicon Con Report 2016

This is the first half of my post-con writing, to be followed by a post about my personal experience and weekend.

Overall, Frolicon is still Frolicon. Circumstances required the venue and date to change this year, which upset a few people, but didn't ruin the event. Every convention has growing pains, and it looks likely we'll weather this one just fine.

Collapse )

All in all, definitely still a convention worth going to for those kinky and/or geeky.

Would you kill me for $100?

I wonder... if I made "all of my social network Friends/Circles/etc" a beneficiary of my life insurance, how big would the shares need to be for someone out there to have enough motivation to arrange my death? Is there someone on my friend list who would kill me for $10? For $100? For $1000?

Sparr Bought A Bus: Week Five

Some Burning Man stuff took time away from the bus this week, but I still got a few things done.

I got the first half of the bed frame built. The cantilever supports are welded and temporarily installed, and there's a platform on top for my current mattress folded in half. I am no longer sleeping on the floor, which is nice. I'll have to take it apart to grind and paint/powdercoat, and to assemble the second half once I can get the heavy duty slides I'm trying to order. While it's apart I'll try to adjust the fit of the supports so they align a bit better.

I decided to temporarily cannibalize the handrail parts that I removed around the first kitchen location. I used them to add some horizontal members to the overhead rails. Now there are enough pieces to support bunk beds or shelves up there. I went with shelves for the short term, with enough free space around them to still grab the rails.

The new shelves are holding most of the long items that I had crammed under the table and seats previously. Wood stock, ladder, brooms, etc. I didn't put the steel stock up there yet but I will. The space under the bed is a good fit for three big storage bins, and the front folding seats have room underneath for four small storage bins. Between those locations and the rear window, I've gotten a lot of stuff out of the way that was slowing me down previously. I also put the hot air balloon and the fourth solar panel into storage.

I started making cardboard inserts for the windows, for privacy and stealth reasons. They are 100% opaque, obviously, so they should be excellent for both. Unfortunately I'll have to remove and reinstall them if I want sunlight through the windows during the daytime other than through the front window or roof hatch. That won't be so bad once I have LED lighting inside. To go with the window covers, I also need to get blackout curtains hung at the front, and to disconnect the light above the front door. I went with white cardboard so that I could get some artistic friends to decorate them eventually.

Intangible progress... I got 15+ people aboard for mobile social activity while I was giving them all rides after a party, to hotels and after-parties. Swapped stories with a few of them, cards with a few more. This is definitely something I want to do more of, especially once the passenger areas are more hospitable.

That's all for now. Plans and priorities haven't changed, otherwise.

Sparr Bought A Bus: Week Four

I am approaching the end of the first month with the bus. Progress has been slower than I'd like, due roughly equal parts to my own laziness, sparse class offerings and a scheduling snafu at TechShop, first drafts of some of the projects not being acceptable, the bus being crowded with stuff due to lack of storage space, and slow delivery time on some of the components. I'm hoping to address at least three of those things in the very near future and speed things up a bit, due in no small part to having received my first parking ticket last night. The nominal reason for the ticket was a street sweeping violation, but they tacked on my lack of license plates. That triggered the start of a 21 day deadline to get it registered and avoid a $121 fine. Despite all of that, I am still making progress, and the space is starting to feel slightly more comfortable with each improvement.

The solar charger seems to be working, despite my not having a way to monitor the battery yet other than a multimeter. I managed to drain the batteries from 25.4V to 25.0V with all my gadgets running overnight, including the lights and fans for a few hours, and it was back up to 25.5V when I checked it after some sunlight. Note to self: Get a low battery alarm.

I built a prototype for the kitchen. It doesn't fit/work well. That's detailed in my previous post. I got most of the rest of the connectors to assemble the whole thing, wherever it ends up going. That included the foot pump for fresh water, the propane regulator and hose and adapter for small bottles, and a few other things.

I partially removed one of the window frames so that I could get behind a wall panel. A significant fraction of the window frame screws are seized with galvanic corrosion (steel screw into aluminum frame). I stripped a couple, and drilled one out. I gave up when I needed to drill out a second one, and will return to that experiment when I have a screw extractor later this week. I did get enough of the frame unscrewed that I could pull it and the wall panel away from the wall. That gave me a glimpse of one of the structural extrusions that I want to use for the table and bed frame mounting. Knowing where that member was allowed me to cut a small hole in the wall panel to get direct access to it.

Good news, the structural member below the windows seems to a similar extrusion profile as the ones in the ceiling holding the handrails. Bad news, it's oriented such that the load bearing channels face up and down, not toward the interior of the bus like they do for the vertical members between the windows. There's an ancillary smaller channel in the useful side of the extrusion, but I don't have nuts that fit it. I've ordered some that might, and will probably end up machining them down to fit. In the long term, this means I need to machine or waterjet cut some adapter plates to make solid mounts to the underside of those members for strong connections, and machine some T-nuts for the smaller channel for lighter connections. In the short term, this means I'm drilling straight through the side of the channel and using screws, effectively treating it like a 1/8" thick piece of angle aluminum. I feel better about this plan given that at least one of the existing installations, the rear upper level retaining walls, also used this connection method for one of their four attachment points.

I bought steel for the table, shower frame, bed frame, etc. I went with a variety of sizes (20ft each of 1x(1|2)x0.125 bar and 1x1x0.125 angle and 1x(0.5|1|2|3)x16GA square tube) which might leave me short for a couple of the final products but gives me plenty to practice with and make prototypes. I got some 1.5x1.5x18GA perforated angle for prototyping connections between my steel tubes and the bolts into the extrusion railes. I also bought a bit of lumber for the table, some 1x2 for the edges and 0.75 plywood for the tabletop.

I built a wooden tabletop and it came out pretty nice. Better than I expected for my first try, not nearly as good as I'd like for the long term. I didn't finish or paint it, and might not if I'm only keeping it for a month or two. I ended up using a lot of small screws to semi-permanently attach the table to the wall, rather than the temporary attachment I need in the long term to use the table as an alternative bed surface by lowering it. I need to investigate attachment methods for the next attempt at a table, since off-the-shelf door hinges aren't going to work as well as I had hoped. I'll probably just buy a commercial restaurant tabletop to replace my prototype eventually, for increased durability and finished-ness. For now, I'm happy that the prototype table is installed and usable. Having a place to sit and work on my laptop or with tools has made the bus feel a lot more home-y.

One side of one of the supports for the roof hatch has started to break. I may have been opening or closing it more forcefully than I should, or maybe it's just dying of old age. I've made a temporary fix with gorilla tape. A less-temporary fix with strapping tape or maybe an epoxy is probably warranted. Eventually I'll want to make replacements for those supports out of metal, once I'm a lot better at welding and a little better at machining. For now, the hatch still opens and closes and stays closed, so there's no rush unless I start going up there a lot more often.

I've ordered a Laveo Dry Flush toilet. I ended up choosing this one despite its higher up front and ongoing cost because I anticipate a guest needing to empty it and wanted to make that as painless as possible for them. This was the only option where the emptying process involves no exposure to human waste.

I received the hardware that I ordered for the overhead rails but half of it doesn't fit. I'm back to shopping around looking for the pieces I need, or cannibalizing parts from other rails already in the bus. I'm probably going to cannibalize in the short term, and then swap out for replacements later so I can put the original parts back where they belong.

I've also ordered a stack of white cardboard sheets big enough to cover the windows. All of the windows have grooves in their frames that I should be able to slide panels into if I can get them cut to the right size. I may do it by hand, or I may do it on the shopbot if I can get my hands on a drag knife or even if I can't, or I may get certified on a laser cutter if TechShop has one big enough. Regardless of how I cut them, once they are installed I'll have privacy at night with the lights on, and nice big white surfaces that I'll need to find a friend to artify for me.

Next steps: Decide where the kitchen is going and buy a commercial cabinet to cut down to fit in that space. Install the sink and stove in that cabinet. Continue shopping for shower pan, and design the shower/toilet enclosures/curtains. Finish short term upgrades to overhead rails. Black out the windows with cardboard. Hang a less temporary curtain at the front of the vehicle, and disable the one overhead light that shines in that section. Make a more permanent set of supports for propping the windows open. Install some sort of temporary stuff storage. Shelves, stacked bins, etc.

Sparr Bought A Bus: Kitchen and Bathroom Planning

I am seriously reconsidering the placement of the kitchen. I'm glad I went with a rough prototype first; I'd be a lot more pressured to keep the current plan if I'd already done the work in real cabinet+countertop materials. I got it put together last night and ran into a number of concerns that I had previously anticipated but underestimated the impact of.

The current location barely doesn't block the electrical panel door, but it does eat up all the useful storage space that I had closest to that panel, which is where all my 5/12/24V power is coming from. I feel like I'm going to want that space in the future for larger electronics, such as the sound system, video recorder, etc.

I like the sink and drain that I got, but they are nearly/barely too deep for the current location. I can make it work, but the drain and propane hoses and installation would be cleaner in a location with more clearance below.

What if the kitchen goes just ahead of the rear door? This will eat up a little floor space, but also even up the open space depth on both sides up front. The kitchen and door on one side would line up with the dining table and seats on the other side. This would move the sink closer to the bathroom, and the stove closer to the dining room.

What will it feel like if the kitchen is in the bedroom area, next to the shower? Too cramped? Too annoying when someone wants to cook while someone is using the bed? Having the sink next to the shower and toilet would feel good, but having the stove there would feel weird.

Speaking of the bathroom... I still haven't chosen a toilet. I'm pretty sure that I want the toilet to be waterproof so that it can go in the shower, both to save space and to provide a seat while showering. That will be important with the shower having a slanted ceiling with 58-74" of headroom. The hot shower component is entirely portable, so I can erect a curtain and platform outside the bus for showering while camping. The indoor shower will be used in the city and possibly while driving.

I think that what I want to do with the bathroom space is to give it about a 3x4ft footprint, with one solid 5ft wall on the short/window side. The wall will be hinged about 2ft off the ground so that the upper section will fold over like a box lid, being the top of the box whose bottom is defined by the shower pan. This will preserve the open view through the bus when it's closed, as well as provide a table-like platform when the bathroom isn't in use, and avoid the need for the shower curtain to completely surround the shower.

Brainstorming, experimenting, and actually accomplishing things... all continue apace.

Sparr Bought A Bus: Week Three

No disasters this week! It's nice to start one of these posts without a "Today I Fucked Up" section.

I managed to give away two of the seats, and am going to give up on the rest in another few days. They are too bulky for me to store right now, and I'm striking out on finding people who want them. If I had a house I'd have already put them on the curb with a "free" sign.

I finished removing all of the unnecessary handrails. All of the verticals below the 6ft level are gone. The one under the kitchen is gone, along with the plastic box it surrounded. The retaining walls in the back are gone. They required getting under the floor, but fortunately there are access hatches at that level, unlike the stuff in the low floor that I need to crawl under the bus for. The only things left to remove now are the wheelchair backrest walls and the last of the wheelchair anchoring hardware.

I've ordered a couple of 90 degree elbows for the overhead handrails. Along with the other connectors I've reclaimed from the unwanted bits, that will allow me to add a second pair of horizontal bars above the living room seats. Eventually I'll want to be able to fold or remove the rails up there to make more overhead clearance in the living room area for aerials, suspensions, etc. I'm not sure how far in the future that is, which will dictate how much effort I want to put into extending the existing rails for short/medium term overhead storage. With two such bars on each side I can put a simple plywood shelf up there, eventually to be replaced with a light framed surface that can be used as a bunkbed. Extending that length further will add a third and maybe fourth and fifth overhead bunk / shelf.

Another round of hardware shopping got a sheet of thin plywood to make up to three prototype kitchen countertops. Hopefully I can hit the design I like, and then repeat it in hardwood (probably butcher block style). I also picked up the connectors necessary to connect the sink drain to the grey water aquatainer, although I forgot to get the adapters to insert my strainer trap. I'll have to add that next time. I haven't started working on the faucet yet because my foot pump hasn't arrived. I'm somewhat considering an overhead water tank at this point, although I might still want a foot-activated spigot to conserve water. I shopped for propane connectors and hoses but couldn't find what I needed and will have to check a specialty store or search online. Last item was a case of 6qt sterilite bins, which I'm going to consider standardizing on for the purposes of making racks and shelves for storing containers full of sorted and assorted stuff.

I decided to throw planning and caution to the wind and install the solar panels sooner rather than later. I couldn't find any layout that I liked for all four panels so I installed just three of them across the rear edge of the roof, behind the hatch, in front of the air intake and exhaust. I put sheet metal screws straight through the roof material, which isn't as secure as I'd like but will do for now. I kept all the screws in 4 lines so it won't be hard to reinforce with long thin strips of steel later. I've also bought some VHB tape for reinforcing and sound dampening and waterproofing the connection points. The wiring is very haphazard, taped to the outside of the bus, with the charger in the engine compartment. Rather than get into all the battery management wiring this early, which is a project I am putting off for when I can get under the bus among other prerequisites, I just plugged in at the alternator, one of the few places that I'm confident there's low-resistance direct connection to get power to the batteries. As I write this, I haven't been able to confirm yet that it's actually working aside from it telling me my batteries are already fully charged. It's night time right now and I'm running the lights and inverter in an attempt to drain the batteries a bit, so that hopefully come morning I will see them charged again, or better yet catch them in the act of charging.

While installing the solar charger I found yet another electrical junction box and well-labeled wire nest, this time inside the panel in the engine compartment that has a few gauges and engine operation toggles on it. I feel like I'm asymptotically approaching at least having seen all of the wiring harnesses. There are still a couple mentioned in the operators manual that I haven't found, but I know where to look for those when the time comes.

I discovered that half of the electrical defroster/defogger in the front windshield works and half doesn't. I'm going to poke at it with a multimeter and see what I can discern. Fortunately the working half is the half in front of the driver, so this isn't a particularly pressing issue.

I got rid of two of the benches to someone at the East Bay Burners social who wanted seating for their shop. I gave the rest to a friend in Oakland who has some storage space and is willing to do the leg work to give them away to good causes. With them gone, the interior feels even more spacious than it did before, although also exposing a lot more floor that I need to clean, and requiring me to improvise a new lock for the rear doors. Aside from the last things I need to unbolt, those seats were almost the last big things to get rid of.

Conversely, I made my first trip to storage to put more things into the bus. I grabbed bins with tools, more blankets/sheets, and some more clothes. I'm finally back to the wardrobe that I kept in the ambulance, rather than just what I packed for the Boston / Road Trip trip. The difference in having 2-3 weeks worth of clothes vs 5 days worth of clothes is a big deal.

I've been giving friends, acquaintances, and strangers rides. It's as fun as I imagined. I also accidentally had a ~15 person party when I parked in front of the burner social and left the doors open. Even with all the stuff in the way, it didn't feel particularly cramped with 6 people sitting down and 9 standing. I take this as a good sign that 20+ will be a viable party size once everything is installed.

Next steps, in no particular order: Build the prototype kitchen countertops, install everything, and see how it feels/works. Order and install propane accessories. Build a working sink faucet. Continue shopping for shower pan, and design the shower/toilet enclosures/curtains. Choose and order a toilet. Finish short term upgrades to overhead rails. Figure out how to get into the walls below the windows to find/see/measure the structural rails there. Build a prototype for the dining area table. Black out the windows, with curtains or foil, for night time privacy. Hang a less temporary curtain at the front of the vehicle, and disable the one overhead light that shines in that section. Make a more permanent set of supports for propping the windows open. Add door sweeps to the front edge of the solar panels. Install some sort of temporary stuff storage. Shelves, stacked bins, etc.
