In this TronicsFix video, Steve buys 7 broken NES game cartridges, priced from $5 – $30, to see how hard it is to fix them. Most of the repairs come down to cleaning the “golden finger” contacts on the edge of the circuit boards and Steve finds that a combo of pink eraser, IPA on a Q-tip, and a metal polishing cloth does the trick. One game had badly corroded pins on a chip and was therefore DOA, another had a short in one of the chips (same), a few required jumping wires to repair broken copper traces. But, in the end, only a couple of the games were beyond basic repairs.
Awesome Woodworking Tips from Lloyd Khan
When I was a teen, I was obsessed with the Whole Earth Catalogs and completely enamored with the work of often-featured designer-builders like Jay Baldwin, Greg Baer, Malcolm Wells, and Lloyd Khan. Khan was responsible for the very WEC-like outsized Shelter publications, featuring crazy, cool, and arty owner-built dwellings. Lloyd is still around, still doing his thing. His Instagram is worth a follow. This particular post is loaded with a number of high-quality construction tips.
Getting to Know the 555 Timer Chip
In this DroneBot Workshop they provide a clear and concise 42-minute introduction to the ubiquitous and versatile 555 timer chip. They discuss how the 555 works, its various modes, and some of the basic projects you can use it in.
A Chemist Explains How Super Glue Works
Brent, of the excellent game crafting and miniature painting channel, Goobertown Hobbies, also has a Ph.D. in chemistry. In this video on his channel, he explains the chemistry behind cyanoacrylate (aka Super Glue) and how the glue actually works.
Electroplating 3D Prints
Via Donald Bell’sMaker Update comes a recommendation for this article on Makezine about how to create faux chrome finishes on 3D prints. The process involves lots of sanding and smoothing of the print, a spray with a copper conductive paint, then an electroplating bath. The results are pretty spectacular.
Testing and Ranking Heavy-Duty Staplers
In this Project Farm video, Todd tests out 14 different brands of heavy-duty staplers. He looks at units from Makita, Milwaukee, Ryobi, Arrow, DeWalt, WorkPro, Bauer, Neu Master, Ework, Bielmeier, Stanley, and Citadel. The staplers were compared for resistance to jams, stapling speed, capability to drive staples into spruce, oak, and composite decking. Bottom line? The Ryobi performed very well and offers the best value, at $84 (at time of testing). The stapler that tested best overall was the Makita, at a whopping $210 at time of testing.
Shop Talk
Newsletter reader Paul Cryan asks:“How do you know if a tip you’ve come across is original enough to report?”Good question, Paul. A lot of it comes down to experience and intuition. I’ve been writing in the DIY space for over 30 years, so I have some sense of the saturation of tips and techniques that are shared. But ultimately, I don’t sweat “originality” as much as I do practicality. If it’s a great tip, even if it’s been around for a while, even a very long while, it’s worth sharing with those for whom it’s new and as a reminder to those who may already know it. I see tips all the time that serve as a reminder for me to finally break down and try it out (or bring it back into my work flow).

I got a lot of responses to my “Shop Talk” post about areas of DIY where you say “Hell, no, get me a pro.” Everyone seemed to be on the same page. Reader Craig best summarized the responses I received:“My dad did almost no home or auto repairs. Not because he didn’t know how, but because he freakin’ hated doing them. Mom, however, might have been able to build a house with a pocketknife and a pair of vise grips. She just had skills…lots of them.”I have done a wide spectrum of things but as I’ve gotten older, I triage everything:If I want to try something, I do.If I don’t want to, I don’t.If it absolutely must be done and I don’t want to do it, I hire it out.No guilt, just a depleted treasury.”

Cool tools really work.
A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful. We post things we like and ignore the rest. Suggestions for tools much better than what is recommended here are always wanted.
Whether you’re a hiker, biker, backpacker, camper, naturalist or simply someone who’s ever been caught in the rain, you’ll treasure these classic all-weather notebooks. The cover is Polydura and the pages are made with a substrate, giving the paper a wax-y feel. The effect: water beads off them, meaning no pulpy mess and no bummer over any lost thoughts or data. They are not a new invention by any means. Back in the 1920s, they were developed for Pacific Northwest loggers. These days, the manufacturer makes both bound and spiral bound books in an impressive array of sizes and types (e.g birding!). I keep a pocket-size, 24-page, staple bound mini-book in the small pack I take cycling and hiking. In the event of a downpour, all my ah-ha moments are safe. If you plan to be in really harsh conditions and want to go the extra mile, you might try one of their all-weather pens. Note: I have not used them — a pencil or standard ballpoint does the trick for me. —Steven Leckart
Before I start a new painting, I usually draw what I want in Adobe Illustrator, and then transfer a printout of that drawing to canvas or board to paint. I’ve tried opaque projectors, but the image is faint (at least on the el-cheapo projector I use) and I don’t really have room to set it up. I’ve also tried using a piece of paper that I’ve rubbed pencil or charcoal on, but that produces a blurry line.
Like an idiot, it wasn’t until recently that I considered the possibility that there might be a transfer paper for artists. Of course, there is one. It’s called Saral Wax-Free Transfer Paper, and it works like a dream. It comes in five different colors, but I can get away with blue and white. It leaves a clear, thin line that erases easily and doesn’t mess up the color of the paint I use. I’m already hooked on it for life.
If you send a self-addressed, stamped envelope to Saral, they’ll send you free samples in all five colors. — Mark Frauenfelder
Anyone doing technical or design work has burned through reams of graph paper. I’m a designer, and I use Whitelines to do technical drawings in accurate scale, which are then turned into 3-D models and die tooling diagrams. Whitelines is the best graph paper I have ever worked with.
The concept is simple and powerful. Ordinary graph paper is paper with a graph of lines printed on it in a light color, often blue or gray. Whitelines is paper with a very light gray grid of squares printed on it. The graph is unprinted, hence, white lines.
This is genius. Pen strokes, and even pencil, are startlingly clear against the background. The distracting visual noise of a printed graph is gone entirely, while retaining the precision and ability to see scale, which is graph paper’s reason for being.
I’ve been using Whitelines extensively for the past few months, mostly for technical drafting on the MakerBeam project, an open source metal building kit like Meccano for the Arduino set. The grid is 0.5 centimeter pitch, perfect for working on a metric standard. With ordinary graph paper, pencil lines are close in color weight to the lines themselves. When scanning pencil marks on ordinary graph paper, the pencil lines often vanish completely. With Whitelines, I can scan a pencil sketch, if I’m satisfied with it, without having to go back over it with pen.
Available in A4, A5 and pocket sizes, as tablets, spiral bound, perfect and hardbound, both lined and graph. Better graph paper makes better drawings, and this is genuinely better graph paper. — Sam Putman
OK, so I wanted to sit down and workout a grand plan for my new garden, so I figure a pencil and some graph paper is the way forward.
Just finding some simple 2mm graph paper with 1cm semi bold and 2 cm bold turned out to be a near impossible task. Then I discovered the Graph Paper PDF Generator at incompetech.com .
It does plain paper, lined paper, multi width, hexagonal, even semi-bisected trapezoid! All completely customizable. And it’s free! — Mark Coffey
Ever have an idea in the shower and have no way to record it…and then it’s lost forever? I use a “Dive Slate”, a small (~4″x6″ ) sheet of sturdy white plastic with a plain old fashioned golf pencil attached. They’re cheap (around $5-$8), available on the net at various dive shops, fit nicely behind the soap holder or hung in the shower and work well; they’re meant to be written on underwater by divers, so unless you shower under Niagara Falls, your thought will be captured until you erase it. — Vincent Crisci
