We had a motivated kid and a willing parent. We had
a project picked out. Now all we needed was to get some parts and
follow the easy set of 5 or 6 steps in the ad in the magazine. What
could possibly go wrong?
We went to the local Radio Shack and the kind
person at the counter wrote down all the part numbers, checked the
inventory, and then informed us that they had all but two pieces in
stock and that no store within 30 miles had both of the
remaining parts. So we would have to visit three stores or order the
parts online. We wanted to do the project that weekend (Memorial Day) so
we opted to do some extra driving.
(Note to Radio Shack employees - when you hand someone a list of part numbers and you know that several of them are "locked" items that require you to unlock the display in order to retrieve them, why not help out the customer instead of making them come and get you for each of the parts?)
Mistake 1: Not getting the parts ahead of time.
By the time we got the parts home, it was time to
head to the neighborhood block party, so we shelved the project for the
night. We would start fresh the next day.
We began by laying out all the parts and we just
jumped right in with step 1. Soon, however, it was clear that there was a
certain base level of knowledge assumed and that I was not at that
Mistake 2: Not reading ahead and preparing the software side of things.
We powered through step 1, eventually, though it
took a while. We had to download and install the arduino IDE, the SD Fat
library, and then get it all working together. I didn't know that you
had to install the library in a specific place.
I figured out enough to get by, thanks to some google searches and
trial and error.
My daughter showed some great determination, but eventually she got bored while I fiddled with the computer.
NOW, finally, we were ready to start putting the thing together. My daughter was once again interested and we stared to work.
Only to discover that the instructions in the
magazine ad were woefully inadequate! They only showed where 5 of the 7
wires/jumpers plugged in! What, oh what, had I gotten us into?
Mistake 3: Duh. You really, really have to read the instructions ahead of time. Sensing a theme here...
We struggled a bit more before my daughter saw the
URL for the Radio Shack DIT site and she managed to find the Critter Cam
project there (http://dit.radioshack.com/pdf/RSWP11_crittergram.pdf).
Wow! The instructions were so much better!
We finally started feeling confident as we figured out where the RX and
TX wires from the camera card plugged in to the SD card shield.
The rest of the steps seemed manageable and we got
the sketch from the github site uploaded with no problems. We plugged
the rest of the stuff back in and took off the lens cap. There's no real
way to tell if/when pictures are taken, so
we just give it a few minutes and then removed the card and took a
look. Sure enough, dozens of black photos (from when the cap was on) and
then, there! Two blurry shots of our hands! It worked!
We struggled putting the project skeleton together
but eventually we managed to get it all in place and secured. We used
some zip ties to hold the case together and we took it outside where it
sat all evening and night.
Now, we realized after we started that it would not
take night photos. That was a bit of a letdown (again, what should I
expect when I'm looking at an ad for a project?) but we figured we'd
give it a shot and see what happens.
The next day we raced outside and retrieved the SD card. We put it in the reader and... Nothing! It took no pictures!
Long story short, we figured out that the power adapter was the culprit so we drove to RS and asked the guy there to test it. He took one look at it and (somewhat condescendingly) informed me that the I had the adapter tip set to "negative."
I stared at him.
"Uh, these things have a negative and a positive, right? Polarity?"
"Okay, sure," I said, encouragingly.
"Well, it's set to negative. See that mark there?"
"Uh, now I do... So...?"
"So we'll pull it off, and turn it that way and then put it back on. There you go."
Yes, he tested the adapter too, just in case, and we seemed ready to go.
Mistake #4 - #n: Really, really, read the instructions!
We took it home, reset everything, tested it via the outlet and were satisfied it would work.
And this time, it really did work!
(except it just took 500+ pictures in a row right when I plugged it in and didn't wait for any motion detection...)
That's something that I'm sure the camera card instructions cover -- something about a jumper setting (which I actually understand!). So, we'll fix that and be good to go...
It's the middle of the day, Memorial Day 2014, and
it's hot in the little room we use for an office. I'm staring at the
screen, trying to understand where it all went wrong. I'm a fit
frustrated. There's a little sweat.
"It says to upload the sketch, dad," says my 12-year-old daughter. "Is there an upload button?"
We're trying to figure out how to use the arduino
IDE. But I've never even seen an arduino out of its box before this
weekend and while I can find my way around a few different programming
languages, I'm unprepared for this part of the
Actually, let me rephrase that: I'm not prepared for any of the parts of the build.
It all started at Maker Faire 2014 in San Mateo.
For some reason, I've loved Maker Faire and the make movement for a
while, but I don't do any "making" -- at least, not the electronic, or
creative, or robotic kinds of making. But the stuff
fascinates me and also my daughters. We went to the 2012 Maker Faire
and the girls learned to pick locks and solder. They had a blast looking
at all of the kinetic art, and they enjoyed the Mentos and soda
fountain (I think it was Diet Coke that year).
I hated the crowds, which got so bad around 1pm that I began to try to steer the family to the exits.
In 2013 we returned, despite the huge crowds, and
we saw more fire, life-sized mouse trap, and lots of electronic
projects. My younger daughter mostly loves the art side of the Maker
Faire, but she did linger at the tables where makers
showed off their stuff. Meanwhile, everyone at the Maker Faire took
their opportunity to bump into me, jostle me, or step on my feet. I was
unhappy and vowed to not return in 2014.
Then we returned in 2014.
My daughters found out that Maker Faire was coming
and begged me to get tickets. I did, we had fun, and even the crowds
seemed nicer this year. I was bruise-free at the end of the 5+ hours we
The girls did the "Learn to Solder" thing again and
then we started looking at fun projects to try. There was no real
discussion or deliberate decision made, we just kept saying "Maybe we
could do that one?" as we walked through.
Eventually my younger daughter and I decided we
would look through the Make magazines at home to look for a simple first
She saw the Radio Shack ad inside the front cover
of Make 38 for the Critter Cam and we decided it looked
possible. We live in the suburbs, but there's a creek nearby and we get
raccoons, possums, owls, squirrels, and tons
of neighborhood cats roaming through the yard. It might be interesting
to see if we could capture any of them in pictures.
Next time: "It's a simple list of parts, I'm sure they'll have them all..." "Why oh why did we pick this one?" "Rivets???"
The pomegranate must have heard me threatening to
chop it down as it currently has three “fruits” that have survived the
mass bloom drop that occurs every year. Maybe it’s due to the drought
year we’re having?
Anyway, the garden is doing well. The kids made
this cement stepping stone, which they put in the ground at the foot of
the ladder to their fort:
Speaking of which, here’s a shot of that
corner of the yard:
From left to right:
-The lime tree (finally recovering from a series of harsh frosts we had)
This weekend we moved the pullets into the big run/coop with the 1 year old. But first, we had to do some maintenance.
We’ve fenced off part of the yard and used it as an
extension of the run that is built in with the coop. That way, during
the day, we can open the pop door and the chickens can roam in the
larger run. We used a light netting and bamboo
poles to construct the pen and it worked flawlessly with the old barred
rocks we had. Over time, the netting has been fiddled with countless
times and lately we’ve been a bit lazy and the netting is only about 2
or 3 feet high in some places. Our current hen
(Cinnamon) easily flies over this and roams the yard for about 5
minutes before returning to the door to the run where she squawks asking
to be let back in to where her food, water, and nesting box are.
So we started by taking everything down, giving the
run a good cleaning/sweeping/raking/etc., and then rebuilding from
scratch. The new fence is 5 feet high all the way across.
UPDATE: Cinnamon easily cleared the 5 foot height, so we clipped a wing and now she’s grumpy but confined…
Also during this time I did some minor maintenance
on the coop/run structure itself (pop door hinges got loose, etc., etc.)
and then once the netting was back up we put all the birds in everyone
got along perfectly. What a relief!
We went to a neighborhood block party and came home
after dark. We went out to check on the birds and realized that we had
forgotten to close the pop door so I was a bit anxious. We could only
find two of the pullets and so a yard-wide
search party began. Soon it evident that the leghorn was nowhere to be
seen. We thought that maybe some predator had swooped down and grabbed
her and we were feeling fairly sad.
Then I looked up in the top of the run and realized
that she had managed to fly 6 feet up to roost on a crossbeam up where
we didn’t bother to look! Phew. Of course, if she can fly 6 feet, we’ll
have problems with her escaping as well.
She did the same thing on Monday
and managed to dislodge the ramp to the coop in the process. Both of
the other two pullets were a mess, running around trying to find/get to
their buddy the leghorn. Looks like we will have our hands full teaching
proper” place to roost at night!
Our 3 chicks are doing incredibly well. We haven't had any issues at all, which leads me to think that two of them be roosters! ;)
We've been slowly acclimatizing them with/to the 1 year old wyandotte. And again, that process is going so well. We started out just having them in a small cage next to the run, and after a few weeks we've started putting them all together in the run (supervised, of course!). Everyone gets along famously, and in fact, the older bird spends all of her time as close to the pullets as possible.
I hope to get some pictures of everyone together as we have a huge list of chores to do in and around the yard this weekend.
