Supplies: Cloth, Miniature Eyeglass Screwdriver, 91% Rubbing Alcohol, Q-tips, and Brasso

This is my setup, and as I mentioned before, I only use Brasso one time to make sure I get all the dust/dirt off the contacts inside the game cartridge. Over using Brasso can (sometimes) rub off the plated gold on the contacts. You don’t have to use Brasso.

Charley’s games (Combat, Missile Command, and Defender) had a tiny bit of dirt on them, but played wonderful prior to cleaning the contacts.

I clean the contacts with Brasso using Q-tips, because you can’t fit your finger inside to clean the contacts with a microfiber cloth. You can scrub hard and you won’t hurt the gold plated contacts. I do this for the top and bottom contacts.

To get the excess Brasso off (sometimes it can leave a residue) I use 91% rubbing alcohol with q-tips to finish the cleaning.

I clean the cartridge itself (outside) with soap & water, though, with a very damp cloth so it doesn’t ruin the sticker or artwork on the cartridge.

I let everything dry for 5 minutes and test the game.

Aww yeah sensor cleaning time!

Aww yeah sensor cleaning time!

Or: how I managed to finally remove remnants of Hawaiin "vog" from my sensor!

You know, some people are very good at reading signs. Me? Not so much…
I’ve been dealing with a ridiculously dirty sensor since January. The culprit? Changing lenses on a helicopter ride over an active volcano. Not something that I would recommend, in retrospect.
I have tried the blower pictured countless times. I have sensor cleaning happening before AND after the camera turns on (an Eneloop-wasting technique, BTW).
I’ve been told how to clean the sensor by a local photographer who I might be shooting with tomorrow (sign #1), recently set up a preset in Lightroom to remove the dust (sign #2) and finally saw some silly post on G+ about simply doing that thing you’ve been putting off forever and getting it done, RIGHT NOW (sign #3).

Ok then, time to clean the sensor.

The silliest part about all of this is that I knew it was dirty while on vacation, and that the kit I used to fix it was purchased the next day. I typically examine my shots on a daily basis prior to hitting the hay while on vacation, and had noticed the 140+ black dust specs on anything shot above f8. You’d notice them too… The next day I went out and grabbed this Rocket Blower knock-off, and what the Kona dealer told me was a last ditch effort: sticky wands!

Fast forward 6+ months and here I am, removing the dust.

Now for the recipe I used (partly so I don’t forget next time):
– Bulb mode, F32
– Corded shutter release
– Camera on tripod pointed up
– Bright light pointed directly down at camera
– Lens removed
– Lightroom in tethered mode
– USB cable plugged into computer

Basically, you take a long shot, look at the dust on your screen, remove the lens, quickly try to spot the dust and dab at it before more gets it, replace the lens, take another shot and repeat.

2 hours later: only a couple of dust spots remain, none in the middle of the sensor!

Surface Changes in Chryse Planitia

Surface Changes in Chryse Planitia

Description: (1977-1978) At the conclusion of the Viking Continuation Mission (May to November, 1978), all four cameras on the Viking Landers – two on each spacecraft – continued to function normally. During the two and one-half years since the landers touched down on Mars, images totaled 2,255 for Viking Lander 1 and 2,016 for Viking Lander 2. The surface around the landers was completely photographed by the end of 1976; subsequent images acquired during 1977-1978 have concentrated on searching for changes in the scene – changes which can be used to infer both the types of erosive processes which modify the landscape around the landers and the rates at which these processes may occur. The major surface changes have included the water-ice snow seen by Lander 2 during the winter at Utopia Planitia, and a thin dust layer deposited at both sites during the dust storms of 1977. The most recently identified change occurred at Chryse Planitia between VL-1 sols 767 (Sept. 16, 1978) and 771 (Sept. 20, 1978) as seen in the lower photo. Picture at top, selected to show similar lighting conditions, was taken during sol 25 (August 15, 1976). The change (A) appears as a small circle-like formation on the side of a drift in the lee, or downwind, side of Whale Rock. This is believed to have been a small-scale landslide of an unstable dust layer which had accumulated behind the rock. Interpretation of this feature would be difficult without an earlier change (B) near Big Joe, a slump which occurred between sols 74 and 183. The new slump is approximately 25- 35 meters from the lander, and just under a meter across. The slumping probably was initiated by the daily heating and cooling of the surface by solar radiation. More importantly, it is now believed that, based on the repeated occurrence of such slumping features, a dust layer which overlies the surface may in fact be redistributed fairly regularly during periods of high wind activity. There are no obvious indications of fossil slump features, therefore similar features must be destroyed on a regular basis. After the end of February, when Viking operations essentially terminate, Lander 1 will continue preselected observations over a period of possibly up to 10 years, following the instructions stored in its computer memory. Earth commands will be required only to initiate data transmission to Earth. During this time, it is now anticipated that one of the yearly planetwide global dust storms may reach an intensity necessary to shift the dust cover around the lander significantly.
