Tell us about yourself!

  • These breadboard sockets are now so ubiquitous that I have dozens of them lying around. Most have removable bus strips held on with dovetail joints. There is no reason you couldn't simply use two complete sockets with the appropriate spacing to connect with any DIP or other module, with or without an intervening bus strip. Sawing a single socket in half lengthwise is a good solution if that's all you have, but that's a lot of needless fuss and bother by my way of thinking.

  • You have documented an outstanding project! This looks so slick that I am unable to find anything to improve upon. I have a bunch of 2020 aluminum lying about, and this looks like the best project to apply it to. Thanks for sharing the design and its details.

  • I'll suggest a time-saver, especially for "repurposed firewood" that most firewood users should have readily available: use a splitting maul, axe, or wedge to get your starting slab out of the firewood. As long as your firewood doesn't have too much twist in it, you should be working with a nearly flat board right away. A bandsaw that can cut a 12" board isn't a small tool that is likely to be available to everyone who wants to try this project.

  • Incidentally, I hope you will share the problems and your search for their solutions as well. Thanks again!

    This is an outstanding project with excellent descriptions, including a fabulous video! I especially appreciated the video details in which you clearly point out configuration settings and show the necessary values, which are sometimes difficult to make out in the captured screen images. You have inspired me to try my hand at a similar project. Thank you for sharing your experience!

  • Some of the links don't make it into the PDF version that can be downloaded, and while you provide a link or two to your website, you never mention it in the text. You may want to add it at least one of the places you suggest using it to contact you for help and components. Thumbs up on the project, by the way!

  • In Step 18, you say, "Vat Option 1 did not work." Step 18 then describes an alternate approach. Why did Option 1 fail? Why do you prefer the other approach?Also, you barely mention the DLP projector. It would be useful to have your input on selecting one for use in this project, which really does interest me.

  • ottoj commented on Info-Sam's instructable Build Your Own Motor Driver

    It takes 3 more transistors and a bit more space on the breadboard. Look up references to H-bridge to get the details. You'll be using another output pin on the Arduino, and an input pin to switch directions. Also have to be careful about changing directions when the motor is running--you might let the smoke out of your electronics. Also watch out for the polarity on your electrolytic caps--they're exciting when you violate them!
