If you are roaming the open source world, chances are you’ve either come across people who have tons of stickers of various projects on their laptops or you yourself made sure it has ample sticker coverage.
But what if you want to sell your laptop, or have to return it to your employer in a clean state? Get ready to invest some elbow grease.
I simply decided to go more with the clean and simple look on my MacBook Pro and so the
stickers had to go. I thought I’d share a very simple way as I found a wide range of solutions varying in complexity and chances of success.
This is only aimed at MacBooks as other laptops (like my beloved Thinkpads) have different surface materials which may or may not react different.
First you will need some paint thinner:
I started by simply pulling off everything I could with my fingers and finger nails. Some stickers are easy, others not so much. Get off as much as possible.
Next get some paint thinner on a paper kitchen towel and begin to rub it first into the remains of the sticker and then in circular motions with some pressure until the glue part dissolves. Keep going and make sure every part of the sticker comes off. Wipe off multiple times to not just spread the remains all over the lid.
Once you got it all off use a clean paper towel with some paint thinner and give it a final wipe. Then use yet another clean and damp paper towel and wipe off the remaining paint thinner (it smells terrible).
The end result should look like this:
Make sure you do this in a well ventilated room or ideally outside. This stuff really can cause some nasty headaches.
Finally made some time to start building the Softrock Lite II SDR
receiver. The original plan was to build it as a pan adapter for my
TS-940S which has an IF out port. Since I no longer have this rig,
and my K3S has a different first IF, I decided to build it for 30m as
a WSPR receiver.
Checking on the frequency counter confirms everything is working as
it is supposed to be.
Next up was the divider stage. All went fine, except with some need to
tidy up my soldering of SMD parts. First time I used a hot air rework
station for SMD parts. Not as easy as I thought, but turned out OK.
Again tested all the steps and made sure the voltage readings for example
were correct. It is really important to do this for each stage to make sure no
errors sneak in and then are harder to find later.
The divider provided the expected signal at the test points with the expected
frequency. So on to the next stages ….
Finally finding some time to post the completed keyer I designed
the board for a while ago.
The populated board
Now I can finally use paddles with my TS-940S. Next version will be the deluxe
edition with USB and LCD display.
The “Hello World” of the embedded and micro controller world seems to be the
blinking LED. Finally got around installing Win10 IoT on a RaspberryPi2 and
deploy some code. All works fine.
