Hacking Scrubbing Bubbles Automatic Shower Cleaner

img_2757Like many, I enjoy a clean house.  There are plenty of gadgets out there that help you keep on top of the various cleaning duties – Scrubbing Bubbles: Automatic Shower Cleaner being one of them.  While some of the gadgets you pick up are really gimmicky, this one seems to help reduce some of the heavy cleaning the shower needs with minimal effort.

Now this doesn’t eliminate the need to clean the shower, and I should be honest here – when it does need cleaning I manage to neatly avoid doing the dirty work, but I can say that the Scrubbing Bubbles cleaner seems to lengthen the time between shower cleanings.

The only bummer is that the bottles are not refillable.  We stretch ours out by only using it every 2nd day or so (instead of every day as is recommended).  It still would be nice to be able to refill with a concentrate and dilute with water.  The catch is – the caps do not screw off, so you can’t open the bottles.

Let’s take a look at how the cap works:

So on the left you can see a close-up of the threaded part of the bottle. Very sneaky, they’ve put a pair of small ‘ratchet’ nubs – there is another pair on the other side as well.  Looking at the cap, you can see the corresponding teeth.  Once tightened down, the cap is very solidly locked onto the bottle.

To hack this – you’ll need two of the scrubbing bubbles empty containers.  From one you will recover a cap, from the other the bottle.  To remove (destroy) the cap, I used a pair of wire cutters and a pair of needle nose pliers.  I started a cut up the side of the cap, then grabbed the edge of the cut with the pliers and peeled it back.  I used 2 or three cuts until I managed to free the cap from the bottle.  Removing (destroying) the bottle to recover a cap was easier, but I used the same basic approach: a small cut, followed by the pliers to twist the material away.  Go slow (and carefully with sharp tools!) since you want to avoid any damage to the part you are trying to keep.

The bottle must be modified to removing the nubs.  The plastic is a hard plastic which seemed to respond nicely to a coarse file I had in my workshop.  A few minutes of work and I had smoothed over the two pairs of nubs – the cap now opens and closes easily.  Now we’ve got a refillable container.

Offline Maps on a MIDP enable Cell Phone

Sure you can use google maps on your mobile phone, but then you’re paying the potentially large data charges (especially if you live in Canada).  If you’ve got an all you can use data plan, you’re probably holding a G1 or an iPhone and MIDP isn’t interesting (or possible for that matter).  However, if you happen to be like me – you’ve got a highly capable MIDP enabled phone, and no data plan.

Inspired by mimg_2410y pending road trip to Kingston to see Tool, I figured I’d see what it would take to put offline maps on my phone.  It turns out to be pretty easy thanks to OpenStreetMap, JOSM, and Osm2GpsMid.

OpenStreetMap is sort of wikipedia for mapping data, if you haven’t taken a look at it – I’d encourage you to do so.  Some areas haven’t been filled in yet, and that’s an opportunity for you to pitch in an help out.  It is pretty impressive how complete the mapping data is.  I see that there is an oMaps application for the iPhone/iTouch.  I may have to get that the next time I’m travelling.  For the Tool concert, I’m leaving the iTouch at home.

The first step is to get some map data, and the easiest way to do that is to use JOSM – the Java based OpenStreetMap editor.  Locate the area you want to download it will only let you grab a (small) city sized area to edit at a time.  Since I was doing Kingston it fit nicely in the limitations of the editor.  Then simply save the OSM to a file on disk.

Now its time to convert that map data into a MIDP Midlet.  This is done using Osm2GpsMid, excuse the somewhat funky pathing in the command it isn’t necessary if you simply put all the files in the same directory (I didn’t).


java -Xmx1024M -jar ../Osm2GpsMid/Osm2GpsMid-0.5.00.jar ../Maps/kingston.osm

The result will be GpsMid-GpsMid-0.5.00.jad and GpsMid-GpsMid-0.5.00.jar.  Install these on your MIDP enabled phone.

Unfortunately my phone doesn’t have GPS/location services – but the search function works well.  The controls are well done: 1/3 are zoom in/out.  Keys 4/6/8/2 pan the map.  Normal cursor key does fine scrolling.   Search is predictive text style, just start typing away and it will ‘guess’ the street you’re looking for (smart).  More details on the GpsMid site.

Certainly not as cool as the iPhone app(s) – but this is pretty slick for my current cell phone.  Nice to know I’ll have a map in my pocket.

iPod Touch 3.0 Upgrade

IMG_1909Apple provides the 3.0 upgrade “free” for iPhone owners, but those folk have either paid a premium for their devices or are locked into multi-year service agreements.  If you have an iTouch, the upgrade is basically $10.  While I would prefer that it was a free upgrade, I feel  obligated as a software professional to pay for the software I use (I like it when people who use my software pay for it).

The 3.0 upgrade adds a bunch of features.  In the brief time I’ve had the update, I haven’t used many of the new features but cut & paste is a welcome addition.  Push notifications look like they will possibly fix the ‘no background apps’ issue, I’m looking forward to trying out some apps that make use of the feature.  I didn’t notice that the web browser was slow, but I’m all about faster browsing.

I wish they had gone further with the bluetooth enhancement – ideally if they had managed to allow me to use my existing bluetooth enabled phone via an iTouch based interface I would have had a budget iPhone.  Imagine being able to dial your current non-Apple phone via the touch and then have it route the headset audio through the touch.  I suspect you’d soon get sick of carrying two devices and would drop the money on a real iPhone.  Oh well, today all that is offered is stereo headset support.

Read on for details on my upgrade difficulties, and how I resolved them.
