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 ...

This was a wonderful hiking loop in Weminuche wilderness. I also section hiked one small part of the continental divide trail. The view is spectacular.

Installing DC to DC charger in Toyota Tacoma

 I had a difficult decision to make. Power is the most important problem in my trips and I was under impression that solar is the best option but I couldn't wrap my head around all the space I need for a decent setup. I don't think anything less than 200w is practical, considering cloudy days or shorter winter days. If you camp for a long time, solar is the best power option but I move and drive a lot. After a lot of research and up and down, I decided to go with a DC to DC charger. I know I can easily use a simple relay and don't spend a lot but I know for experience that any addition to car's electrical system should be taken more seriously. Saving extra $50 doesn't worth screwing around your car's electric system. You can easily put a lot of work load on the alternator and fry it in time. Out of many car problems, the alternator is the only one I don't hesitate to fix. Renege had a big sale so everything was a perfect match and I got my DC to DC charger. ...
