One of my favorite youtubers is Matthias Wandel, who builds all kinds of extremely practical stuff out of wood and thrown away furniture. The most impressive aspect of his videos IMHO is that all of his woodworking machines are actually built and/or improved by him - almost nothing in his workshop is store bought.
Linus Media Group is a relatively small production company, which mostly makes videos about consumer electronics, PCs and networking gear. They filmed quite interesting move vlogs too, about the difficulties they've faced while moving to a bigger and better office, and they also go live every friday with The WAN Show - a show about tech news and life.
Tek Syndicate is another tech channel, with lots of humor and intelligent debates. Their weekly show is The Tek with Logan and Wendell (and guests), but Logan also hosts (monthly?) a Q&A show called inbox.exe and his girlfriend, Pistol, appears in WASD with 1-2 guests (bi-monthly?). They are also organising a LAN party in Seattle, for which you can buy tickets for 75 USD until the end of the year, after that it's 90 USD.
JayzTwoCents earned my respect by doing most of the work alone. He doesn't have a camera man, a proper studio or a video editing crew (like Linus Media Group has :P). Jay's speciality is water cooling and video cards, but you'll find all kinds of videos on his channel, including his weekly live show with Barnacules Nerdgasm - Tech Talk.
Barnacules is a more adventurous tech tuber, as he worked for 15 years at Microsoft. Now, after getting fired, he does a lot more of 3D printing, CNC, vlogs, unboxings, plays with drones ...etc.
Paulshardware and Kyle's Awesomehardware Network started at the same time. They both worked at NeweggTV, and decided to make videos by themselves. They also do a weekly live show, which is pretty well organised, with clearly defined segments and duration.
UnboxTherapy is completely different from the previous channels. It's mainly focused on professional unboxings, done right, with appropriate lighting and cameras.
So these are my personal favorites, but there are a lot more interesting tech tubes out there. Which one is your favorite? Feel free to leave a comment below.
