### Vote on a VR headset for PS:1 and sending delegates to NOMCON

We’ve got two votes scheduled for tomorrow, May 1. You can still vote by proxy if you get your vote in today. Otherwise, show up at tomorrow’s member meeting to weigh on these matters of urgent public concern.

### Can I geotag/use Flickr/post daguerrotypes instead?

Not at the moment, no. It has been suggested that we expand the feed to include pics that have been geotagged at PS1, or that mention the @pumpingstationone Instagram account, etc. These are all good ideas, but the plugins we are using don’t do this out of the box. (You can however tag your photos with #madeatpsone instead, if you like typing extra letters on your phone.)

### What else can I do?

The post We have a photo stream–and you can post to it appeared first on Pumping Station: One.

### Results from The Great Drill Contest

As promised, we tested some drills. The testing wasn’t exactly scientific, but the results pass the smell test and provide some interesting insights as to the relative value of different drill types.

Spoiler alert, no equipment was visibly damaged in the collection of this data.

Read on for all the gory details.

# The Drills

We set out to test a variety of drills, corded and cordless, at a variety of price points. These drills were all things that Ben, Garrick and Kevin had around their houses or the OMG Makerspace, and none were purchased specifically for this test. There’s something of an excess of Ryobi entries, but that’s just what we had.  The idea for this test came about when Ben purchased an ancient Black and Decker heavy-duty drill for \$10 at Habitat Restore and said something to the effect of “I bet this drill could out-drill about anything”. We punched a few 1″ holes in a scrap of wood and decided that a more complete test was in order.

# The Bits

We originally tried to select a variety of drill bits with different characteristics to test torque, speed, and so on.  I’d had visions of hole saws and forstners and a dozen sizes and pitches of twist drills, and when we saw the heap of stuff on the bench, we settled on the following 5 bits, since we didn’t want to spend all weekend drilling holes.

• 3/8″ Ryobi Titanium-Nitride-coated twist drill
• 1″ Harbor Freight Black Oxide twist drill
• 3/4″ Irwin self-feeding paddle bit
• 1″ Irwin SpeedBor tri-wing self-feeding bit
• 7/8″ self-feeding auger

None of these bits were purchased for this test or particularly new; as with the drills we just sort of used what we had.

# The Materials

Originally, we were going to conduct all drilling in 2″ hard maple, but ended up testing a few bits that stripped when trying to self-feed, so we ran the Speedbor and auger in a 2×4, drilling the 1-1/2″ way with the Speedbor and the 3-1/2″ way with the auger.  Except for the auger, all tests were conducted with the bit in a vertical orientation.

# Testing Protocol

Times are approximate, and were taken with a stopwatch.  Each combination of bit and drill was only tested once (because we’re lazy) so this represents pretty weak science. A hole was considered drilled when the bit broke the lower surface of the lumber, to prevent measuring error where self-feed bits stop feeding once the screw tip breaks through, and where twist-drills sometimes seize if a flute catches wrong.

To account for differences in operators, we tried to use the same person for all tests with the same bit. We tried to regulate drilling pressure based on bogging, optimizing each drill to “max work”.

This chart shows the time spent completing each test. A few of the drills, particularly the elderly blue Ryobi and the 12v Bosch, had a few holes that they were unable to finish or that they couldn’t even attempt. The Bosch has a 3/8″ chuck, and the 1″ twist drill has a 1/2″ shank.

Clearly some drills were MUCH faster than others, with the fastest overall being the corded Milwaukee Hole Shooter, a very typical 850-RPM mid-duty drill. However, the standout performer in most tests was the 20v DeWalt, which came very close to the Milwaukee’s total time and beat it soundly with every bit except the 1″ twist drill. This really came down to gearing, as this drill had a 3-speed gearbox, and was able to spin the larger bits in the middle gear, giving it more RPM than the rest of the field. The rest of the drills with a shiftable gearbox, including the Metabo corded drill, needed the torque of their lower, slower gear for every bit except the 3/8″ twist.

Pay close attention to the Bosch 12v and the Ryobi 18v Brushed – at a glance, their scores look excellent, but neither drill was able to complete every test. The Bosch was only able to run the 3/8″ twist drill effectively; this shouldn’t really be a surprise, as it was designed for much lighter duty than the rest of the field. The Ryobi was able to complete every test except the 1″ twist drill (which really isn’t something you’d often run with a hand drill anyway), but it posted the second-slowest score for each test. Interestingly, while its blue predecessor consistently placed last, it was able to complete a hole with the big twist drill.

There are two other interesting comparisons here – first, we have two brushless drills alongside comparable brushed drills from the same manufacturer. While both brushless drills were able to outperform their brushed cousins (aside from a surprisingly slow time from the brushless Ridgid on the 1″ twist drill), they were nevertheless beaten in every test by the brushed DeWalt. Second, look at how the brushed Ridgid stepped up its game when given more power from a beefy 5 Ah battery pack – Upgrading the basic drill with the big battery was nearly as good as buying a brushless drill.

We struggled to come up with a unified measurement for the value of each drill, and settled on “Average Holes Per Minute, Per Dollar”.  We excluded the 1″ twist drill scores from the test, feeling that was a fairly abusive use of some of the 18v drills and one most owners wouldn’t attempt. We also left the Bosch out as an outlier.

To summarize, it’s hard to argue with a good mid-duty corded drill, with both the Milwaukee and Metabo placing very highly and successfully completing every test. This shouldn’t really be a surprise, as both drills are geared for roughly twice the speed of the low gear on most of the cordless drills, and have plenty of power to back that up. The heavy-duty Black and Decker scored poorly, in large part because none of these bits actually stressed it enough to justify the high price tag commanded by such a drill. It only comes into its own when very heavily loaded, as shown by its best-in-field time with the 1″ twist drill. It would be much happier mixing drywall mud or spinning a 6″ hole saw, tasks which would likely have destroyed most of the other drills on test.

The cordless drills show some more interesting variation. Thanks to its low cost, the brushed 18v Ryobi easily tops the chart as an outstanding value, as long as you can accept slower drilling in most situations (and recognize that truly heavy tasks will require a different drill). Beyond that, you basically get what you pay for. More expensive drills drill holes faster. The brushless models may not have blown away the performance of the brushed drills, but their modest price increases reflect this and leave them as a very reasonable option. Meanwhile, adding a large battery pack is a great way to bring new performance to an old drill, but is a terrible value if you’re buying both drill and battery at the same time.

### Screening „The Cleaners“ 6. 4. 2018

Wir freuen uns in Zusammenarbeit mit der Heinrich-Böll-stiftung
ein Screening des Films "The Cleaners" zu präsentieren.

Film & Gespräch

20.00 Uhr FILM
21.30 Uhr Gespräch mit Moritz Riesewieck und Hans Block (Regisseure)
22.00 Ausklang mit Musik und Getränk

„THE CLEANERS“ ist eine Reise in eine versteckte Schattenindustrie in
Manila mitten in das Herz digitaler Zensur – dorthin wo das Internet von
kontroversen Inhalten „gesäubert“ werden muss. Wer kontrolliert, was wir
sehen und was wir denken?

THE CLEANERS enthüllt eine gigantische Schattenindustrie digitaler
Zensur in Manila, dem weltweit größten Outsourcing-Standort für Content
Moderation. Dort löschen zehntausende Menschen in zehn Stunden Schichten
im Auftrag der großen Silicon Valley-Konzerne belastende Fotos und
Zensur oder Sichtbarkeit von Inhalten werden so an die Content
Moderatoren outgesourct. Die Kriterien und Vorgaben, nach denen sie
agieren, ist eines der am besten geschützten Geheimnisse des Silicon
Valleys.

Die Grausamkeit und die kontinuierliche Belastung dieser
traumatisierenden Arbeit verändert die Wahrnehmung und Persönlichkeit
der Content Moderatoren. Doch damit nicht genug. Ihnen ist es verboten,
über ihre Erfahrungen zu sprechen.

Parallel zu den Geschichten von fünf Content Moderatoren erzählt der
Film von den globalen Auswirkungen der Onlinezensur und zeigt wie Fake
News und Hass durch die Sozialen Netzwerke verbreitet und verstärkt
werden.

Die utopische Vision einer vernetzten globalen Internetgemeinde wird
endgültig zum Alptraum, wenn hochrangige ehemalige Mitarbeiter der
Sozialen Netzwerke Einblicke in die Funktionsweisen und Mechanismen der
Plattformen geben. Durch gezielte Verstärkung und Vervielfältigung
jeglicher Art von Emotionen, werden die Plattformen zu gefährlichen
Brandbeschleunigern, die soziale, politische und gesellschaftliche
Konflikte anheizen und die drohende Spaltung unserer Gesellschaft
vorantreiben.

Die Regisseure Hans Block und Moritz Riesewieck erzählen in ihrem
Debutfilm vom Platzen des utopischen Traums der Sozialen Medien und
stellen die drängende Frage nach den Grenzen des Einflusses von
Facebook, YouTube, Twitter & Co auf uns und unsere Gesellschaften.

### Art, LEDs, Tables, Shocking!

What’s been going on at the makerspace? A few members have been making art for the WMSE Art & Music event coming up. Kathy H. used a variety of gears in her piece.

Jack has been working on trying to hack some LED lights to work better with the high speed photography he does. A few members have had good advice, so we’re hoping it’s not too complex.

William finished up this beautiful table. The wood top looks amazing and the pipe legs are functional and make taking it apart very easy.

Mark has upgraded his Van de Graaff generator to throw bigger sparks and make bigger shocks! If you haven’t been shocked by it in the past, look forward to the next event where he brings it out to play.
