A Vacuum Pick Up Tool For Not A Lot

September 18, 2022 by Jenny List 13 Comments

When working with grain-of-dust surface-mount components, one of the tools which makes a huge difference is a vacuum pickup pen. Instead of trying to move the part with tweezers and succeeding only in flicking it into the middle distance, a tiny rubber suction cup with a vacuum feed allows you to pick it up and place it exactly where it is required. Unfortunately, good vacuum pickup tools come at a price, and very cheap ones aren’t worth the expenditure.

This is where [TDG (Béla)]’s SMD vacuum pickup tool comes in. The problem with the cheap tools is only that their manual vacuum is ineffectual, they come with the required array of probes with the suction cups. The solution is to take a small vacuum pump with a low voltage motor and attach it with a 3D printed adapter to the business end of a cheap vacuum tool and make a useful tool the result.

There’s a short video of the tool in action that we’ve placed below the break. It’s a bit noisy, but it’s obvious that it performs well. Control is via an air hole in the side of the 3D print, place a finger over it and the full suction is directed to the tip. The result is simpler and cheaper than previous contenders in the budget vacuum pickup stakes.

Hackaday Links: The 2017 One

January 1, 2017 by Brian Benchoff 21 Comments

You screwed everything up last night. The end of 2016 had a leap second, so instead of the seconds going up from 57, 58, 59… 00, there was a 61st second in the last minute of the year. Yeah, 2016 just wouldn’t quit. [Michel] built a device to keep track of 2016’s leap second using GPS, and everything worked beautifully.

Remember MechWarrior? There’s a reason those mid-90s games used mechs instead of more organic characters. Computers couldn’t draw that many polygons, making MechWarrior a stylistic choice driven by the limitations of technology. Here’s a real MechWarrior that could rip your head off without trying.

The Hackaday Retro Edition is a Web 1.0 version of our main blog, and a challenge to retrocomputing enthusiasts. [PK] recently got his Psion Series 3a surfing the interwebs with a little help from PPP and a Raspberry Pi. He also got a Psion Series 7 online using the same method, but that was a little more anti-climatic.

The NES Classic Edition costs too much, the cords are too short, and you can’t play anything but the pre-installed games. There’s a solution to this: [Andrew] has been working on the Beagle Entertainment System for a while now, and it’s ready for a proper release. The BES uses the SNES9X, VBA-M, and Nestopia emulators, with the original ROMs, and has a ‘shield’ for SNES gamepads. You can’t do better than this, and it’s cheaper than the NES Classic Edition.

Vacuum pens, or vacuum pickup tools, or whatever you want to call them, are really useful when working with SMD parts. You can build your own out of an aquarium pump, duct tape, a lighter, paperclip, and a mechanical pencil, but that lacks the elegance of a footswitch-operated, solenoid valve pickup tool. [Dave] built a great version of a vacuum pickup tool from scratch for less than $200. There’s NTP fittings on here, so you know it has to be great.

Terrible news! I’m in Vegas next week for CES. While I’ll be spending most of my time figuring out ‘which internet of things is best internet of things’, I might have some time for a Hackaday CES meetup.

The best idea I have for a Hackaday CES meetup is the Fun Dungeon in the Trashy Castle. It has Skee Ball and Crazy Taxi. If you have a better idea of where Hackaday fans and aficionados can meet up for an hour or two, leave a note in the comments below.

It Sucks To Pick Up The Pieces

August 1, 2015 by Kristina Panos 11 Comments

Jigsaw puzzles are a fun and interactive way to spend an afternoon or twelve, depending on the piece count and your skill level. It’s exciting to find the pieces you need to complete a section or link two areas together, but if you have poor dexterity, excitement can turn to frustration when you move to pick them up. [thomasgruwez] had the disabled and otherwise fumble-fingered in mind when he created this pick and place jigsaw puzzle aid, which uses suction to pick up and transport puzzle pieces.

The suction comes from an aquarium pump running in reverse, a hack we’ve seen often which [thomasgruwez] explains in a separate Instructable. A large, inviting push button is wired in line to turn the pump on and off. An equally large and inviting momentary switch turns off the vacuum temporarily so the piece can be placed.

At the business end of this hack is the tiny suction-cupped tip from a cheap vacuum pen. To interface the pen head with the pump, [thomasgruwez] designed and printed a rigid straw to bridge the gap. With utility already in mind, [thomasgruwez] also designed a ring that can be bolted to the straw to house a steadying finger of your choice, like the pinkie hook on a pair of barbers’ shears.

Our favorite part of this hack has to be the optional accessory—a tiny platform for quickly flipping pieces without cutting the vacuum. Check it out after the break.

This Hackaday Prize Entry Sucks

July 31, 2014 by Brian Benchoff 11 Comments

Sucker [K.C. Lee] is busy working on his entry to The Hackaday Prize, and right now he’s dealing with a lot of assembly. For his entry, that means tiny SMD parts, and the vacuum pen he ordered from DealExtreme hasn’t come in yet. The solution? The same as anyone else who has found themselves in this situation: getting an air pump for an aquarium.

For this quick build until the right tool has time to arrive from China, [K.C.] took an old fish pump and modified it for suction. He doesn’t go over the exact modification to the pump, but this can be as easy as drilling a hole and stuffing some silicone tubing in there.

The ‘tool’ for this vacuum pen is a plastic disposable 0.5mm mechanical pencil. [K,C.] found this worked alright on smaller parts down to 0402 packages, but heavy parts with smooth surfaces – chips, for example – are too much for the mechanical pencil and aquarium pump to handle.
