Tech-tut was born from a passion of electronics and computers. It was named tech-tut, which is short for technical tutorials, but is not technically tutorials. The site has turned into a blog of technical experiences with the hope that it is more enjoyable than a step-by-step manual. If you want step-by-step then buying boxed furniture is a better route.

Tech-tut is more like a tool box that tells stories. The original idea for Tech-tut would have been more like a Garmin GPS, but that seemed as if it might get in the way. Tech-tut wasn’t just created to get something done. It was created because there’s more enjoyment in creating something than in the finished product.

While the processes and tasks are written in a blog-like fashion, Tech-tut tries to include as much documentation and illustrations as needed to make any task seem simple. We hope that you enjoy your stay. We strive to improve the site’s functionality as much as we can. Please drop us a line through the comments if there’s anything we can do better.

I started my interest in electronics as a child, around age 7, when I was given my first Radio Shack 50 in 1 electronics lab for my birthday. I didn’t learn anything, but I could pick up great AM radio stations on my crystal radio. The obsession got old so the kit was filed away in the toy chest. It would be many years before the fever would catch on.

In 2007, 18 years later, I found a magazine on the shelf of a big bookstore. It was volume 1 of Make:technology on your time. The article that had my total attention was about building a credit card swiper. I just had to have it, but I didn’t buy it. On Christmas day, I opened a small magazine-shaped present to find the exact magazine I was looking at. My wife knew that I wanted it so she bought it for me. She had no idea what she had started.

I began buying tools and parts to build my first electronics project. Radio Shack started getting multiple weekly visits. Digikey.com’s site was reading my cookies. This hobby was getting on its feet fast. It’s been 7 months since that first project. I’ve read every issue of Make to gain new perspectives in the electronics world…14+ 24 issues!

The final straw to my addiction to electronics was when my wife suggested that I go to the local tech college to learn more about it. Now, Clint and I bring you TECH-TUT.COM. We take our research and bring it to you so that you won’t just build a project, but you’ll learn about it, too.

I love electronics technology, and I always want more knowledge. Please remember that to me it’s “More than just a project!” It’s a learning experience.

My education:
Diploma: Electronics Technology, 2009, Moultrie Technical College

Bachelor’s Degree in Electronics Engineering Technology from DeVry University. March 2012.

  1. I have a Firestorm 18v drill radio/charger that has stopped charging. I don’t have a meter but the radio still works. I have pics of the circuit board.

  2. Hi, regarding the B&D charger, did you ever measure the AC voltage of the transformer? I have the type with an AC transformer and the full wave bridge rectifier in the base/battery connector. Marked on the transformer is 17.4 VDC, which is the post bridge voltage, not the AC input to the bridge. My primary is cooked. Thanks for the writeup on this!

  3. The A/C voltage of the transformer is probably nominal at 17.4VAC when fully loaded. It should measure a little more at the unloaded output of the dc jack or contacts of the battery charger. When a transformer is loaded, the output voltage drops slightly.

    I suggested a replacement somewhere in the comments section with a link to Jameco. They have an 18v transformer that should work just fine. Nobody has given me any feedback as the whether it worked, and I wholly believe that if the transformer blew that there are bigger issues in the circuit.

    Let me know if there’s anything else I can help with.

  4. Hello,

    I just finished building a Little Gem cigar box amp via your Instructables article–very helpful!

    I’m completely satisfied with how everything came out, except for one thing. My volume knob is not acting as it should. It only works on full blast. I used a 100k ohm pot that I purchased from Amazon (http://www.amazon.com/o/ASIN/B00AO9JOE0?tag=adapas02-20). Is that where my problem is? Should I bite the bullet and order a more expensive one from Jameco? I noticed in your video that you said that you’ve fixed a volume problem. Did I just follow some older instructions? Should I reroute something or go with a completely different pot?

    Also, I’m new to this and have no background in electronics, but I’d like to learn more about what is happening on the circuit board I built. Any recommended literature or websites for a new guy?

    Thanks and thanks again!

  5. Robbie, I’m sitting over here in Spain and can’t get any parts for my B & D PS 1800 drill. I checked the adaptor and it only has a 0.3 output, basically it doesn’t work anymore. My question: I happened to have a generic brand adaptor with me, 18v output as required but the B & D charger is 210mA and the Generic is 1000mA. Can I use my generic brand without damaging the drill? Thanks, Steve

  6. I believe that you can use the generic one because the circuitry of the charger limts the current. Hope this info helps. I also apologize for the delay in response. I’ve been weeding through 10′s of thousands of spam comments. I’m finally caught up to the year 2014 I think.

  7. As stated a few times to tohers, today, I’m 6 months behind in clearing out my spam comments. Which volume knob design did you use?

    Shoot me an email: robbie .@. tech-tut.com

    I’d be happy to hear about your war story with the volume knob. I found some 100 ohm pots somewhere online. They work much better. Shoot me some photos of your work. I’d be happy to explain how the dad-blame thing works, too. Follow me on Twitter, too. @techtut
