Sometimes two wrongs make a right!

 1- When I was an undergraduate student, I started taking electronic courses for my elective coursework. It was supposed to be a more science course and not much of engineering but they made a mistake and sent us an engineer instructor. So instead of learning about semi-conductors, he started teaching us about designing circuits, logical circuits and wi-fi transmitters! It appeared to I made a wrong judgment.


2- Couple years back, when the pandemic lockdown started, I decided to use a Raspberry Pi for remote access. One of best decisions of my life! The following decision however wasn't very smart; I purchased a UPS hat just to make sure a full time access while I can't go on campus. Well the hat was designed for version 3 and din't support my version 4 and it didn't worth returning, so it was laying around and reminding me of a wrong decision.


3- Last week I was frustrated by unstable solar panel charger and in a moment of enlightenment I found a perfect solution for it. A 5v UPS can stabilize the solar panel output, so long story short, with a little work and soldering and remembering some of those electronic courses, I made a nice solar charge regulator out of a UPS, so when it's full sun, both UPS and any other attachment will be charged but when the sun is behind clouds, the UPS will charge the attachment with the reservoir battery.

Nice! so sometimes two wrongs can make a right!

DIY ultralight pyramid tent for 2+ or 1+dog or 1+ bike

 This is my new DIY project. I have been making tents for last 5 years and I've tried different types. When I started backpacking I purchased a double wall, fully enclosed tent  (so called ultralight tent; market crap).  Most people don't really need these tents and they are not ultralight at all. I switched to a tarp when I started thru-hiking and I fell in love with it's simplicity. Tarp is fantastic. I tried copying zpacks solo tents then. It is a great design.   This time I was looking for a larger tent that can fit my dog as well and it's not as miserable looking as a tarp (people think you are broken!). I always resisted the idea of using a pyramid tent but after a lot of thoughts I settled down with a pyramid tent and I must confess this design offers fantastic features. Here how I did it.   Materials: I ordered all materials from:  https://ripstopbytheroll.com/   but I have used https://www.questoutfitters.com/ in the past and I enjoyed doing ...

New Wood Stove

Finally pulled the trigger and got the wood stove. Although it is not as small and as cheap as many other options, and there are many hassles, I like the aesthetic of it and it also gives me an option of using my MSR stove safely. I have been heating my winter journeys with MSR and cracked window and CO detector, but this sounds safer and more flexible. I spent a day next to pond and build the basic frame and tested the heater. The first impression was good! This is not mounted, it is just a test

Looking for winter in Utah, we found it in Texas

In previous years trips, I have always been stopped by a cold weather at one point, so I had to turn around at some point and head south. Although I have full clothes and sleeping system for very cold temperatures, but the main problem is that my comfort zone is very small and I can't move around a lot. This time I was focused on ideas to improve the cold weather comfort and test how far I can go. As a side note, I have learned that holidays are not good times to travel to places with good weather, nevertheless Christmas is one of those times that I will be miserable staying home. I always have very nice neighbors and friends and their attempt to make sure I am not feeling lonely makes me feel pathetic. So it is the best time to leave the town and go somewhere. If they ask why, I would say I am missing the snow. And if they say, well, you can just drive a shorter distance to the north and see the snow, I would say I miss the desert. And it is true, I miss snow and desert. The magic...
