While in the course of a recent project, we ended up needing a machine to perform a particular operation. The operation was one that falls squarely into the (rather narrow) set of things that you would expect a “Dremel drill press” to be ideal for. And so (1) we got one, (2) found that it wasn’t very good and then (3) found an excellent alternative: The Drill Press Plus by Vanda-Lay Industries.
… yay for creative kits that cause you to go out and (re)learn stuff! The cool thing about the 555 chip is that it is very much a building block to bigger things. There are plenty of resources out there for 555 applications and project ideas. I’d like to thank Eric Schlaepfer for his awesome kit idea and Evil Mad Scientist for helping make it available to the masses!
This is one of the coolest things that you can actually buy. It is a Klein Bottle Opener by Bathsheba Grossman. It is made in the shape of a Klein Bottle, a 3D representation of a single sided shape. And it opens bottles. It’s a 3D printed stainless steel sculpture that fits nicely in the hand, giving you just the right kind of leverage; an absolute pleasure to use.
But— and this is where we were caught off guard— there’s a second great, yet completely independent, kind of Klein bottle opener out there: the Beverage Tool by Klein Tools. Klein tools is quite truly (as they say), “the #1 choice among professional tradesmen.”
We happened upon this gem at Hand-Eye Supply, the Core77 store, while visiting Portland, Oregon. As far as we can tell, it was there because they like well-made tools, including those from Klein, not because they like mathematics.
The tool has convenient “Tip-Ident” mark in the shape of a bottle cap so you can quickly find it among other tools.
And now, dear reader, you know where to get a complete set of Klein bottle openers.
Interestingly, none of the electronics projects requires programming. Shred refers to music, as many of the electronics projects are audio based. Many of the non-electronics projects are also musically inclined, but there is plenty for everyone in this book, from boomerangs to rockets.Snip, Burn, Solder, Shred is a good introduction to making stuff, and is clearly oriented toward doing things with kids. It would be nice if it had full-color photography. Some of the projects have supplemental material which is worth checking out on the Snip Burn Solder Blog. Yoshihito Isogawa are slim and nearly wordless. The main exposition happens in the table of contents, where the symbols that head each section are described.
The body of the books unfold with beautiful full-color photography. The contraptions are cleverly constructed of different colors to make the mechanisms and assembly clear.Many of the assemblies seem obvious in retrospect, but the thought that went into them is deep and clear. Not all of the assemblies are obvious at first glance, and many are quite complicated, like this gear reduction assembly that allows two speeds in addition to direct gearing. For anyone who loves Lego, prototypes in Lego, or loves mechanical assemblies, these books are definitely required viewing, and we’re not sure how we lived without them for so long. (Full disclosure: we received these review copies from No Starch Press, and Evil Mad Science is mentioned favorably as a resource in Snip, Burn, Solder, Shred as a resource. That could have influenced our opinion. Also, we like Legos.)

We stopped by Japantown in San Francisco the other day and picked up an absolutely hilarious toy in the Japanese dollar store. Drawing straws meets the game Perfection in the “Party Potato”. Each person pulls a french fry out of the container. When the right french fry is pulled out, the spring is released and the french fries fly.
You don’t have to be able to read Japanese to understand these fabulous instructions. Two of the french fries are attached to strings which trigger the spring. It is awesome to see the plastic fly!
We recently had occasion to order a lot of toothbrushes, and received a catalog with our shipment from Practicon Dental. There are few things better than a catalog specific to a particular industry. There are so many items that can be applied to various projects having nothing to do with teeth. I’ve never noticed a small vacuum former in a catalog before. There are compartmentalized storage boxes have plenty of utility beyond storing dental impressions. Diamond wire (listed as diamond floss) could be very useful to have around for filing in tight places. Another interesting tool I hadn’t seen before was a small sandblaster.
If you know someone who need to be scared into proper dental hygiene, you can get gross-out posters of what happens when you don’t take care of your teeth. Speaking of scary, for your next ultra-creepy halloween costume, there are “Marvy Masque Cone Face Masks,” which are sure to frighten: especially the clown version. I’m not so sure they will “increase smiles, decrease anxiety” as claimed.
On the less useful, but more interesting front, there is information on dosimetry services so you can track your x-ray exposure. You can order business card dental floss packets. I’m thinking that “tidy tube winders” would make a great give-away for people with as many half-used tubes of glue as we have. But one of my favorite items were these adhesive-tip applicators, which “help you securely hold and place fragile or small” things. Those definitely fall on the useful side. I’m not sure what for yet, but I’ll think of something.
Clearly there are many tools and supplies in the Practicon catalog that are applicable to a much wider audience than just dental practices. We may have to order from them again, and not just for bristlebots!
When I reviewed the Feb. 2007 Lee Valley catalog, reader Dennis suggested we get the Garrett Wade Tools catalog. Excellent suggestion! We love drooling over tools, and the Garrett Wade catalog is a great place to do that. They carry a wide variety of “Tools for Enthusiasts,” primarily precision woodworking tools. They also carry high-end knick-knacks and home and garden items.
