How to disable barcodes

What's a fast and subtle way to disable barcodes? Say I have multiple barcodes close together [pic related] and i only want one of them to be read be the laser scanner, how to you block the others?
Stores usually block a few lines with a black marker but that wouldn't be very subtle.
Will putting a clear sticky tape over it work, just like when you put a tape in an optical mouse?
I have to ask since I can't experiment myself: no barcode scanner. And yes, I've Googled several methods: black marker, white correction ink, reprogramming the database, printing barcode stickers. All of which are not very subtle and/or practical.

DIY Extra Sensory Perception!
How would you go about, say, making a glove which produces pressure at the fingertips?
Or creating your own Feelspace belt?
Any cheap & usable methods to produce sensory input.
To clarify, by ESP I mean, getting data from a computer, GPS, Internet, etc. and transform it to a form the brain can comprehend... Read the article. This is a really cool thing!

Hi DIY I am starting my own business selling snacks, drinks, and shave ice. The aspects of the business aside, I was wondering if building my own shave ice machine would be cheaper then buying one.
I know this would be harder and my main issues is that I don't know how to weld nor do I have easy access to machining equipment... so really I think I'm asking if you could make a shave ice machine out of stuff from places like Home Depot. Any thoughts, tips, or ideas would be helpful.

So, I have this electric motor. It's rated at 1 horsepower, 90 volts DC. It's surprisingly small and light for that sort of power, and I'd really like to use it for this electric bike project I want to do. The motor should draw just over 10 amps at maximum power.
Now, the obvious issue here is that 90 volts is a lot of voltage for batteries to supply. I figured I have two choices here: eight 12v batteries, or three 36v batteries. I would prefer the latter, as I don't really think it's practical to use 8 12v batteries.
From what I can find, though, any 36v battery with any significant current is in fact made up of three 12v batteries in series. So I would need at least 8 of them after all. Anybody know, is there a better way I can power this motor, or should I try and find a new motor?

I harvested three of these projection lenses from a rear projection tv my neighbor was throwing away, and I want to make an RGB lamp out of this one.
My basic idea is to get a pvc floor flange of matching size and mount it to the bottom of the lens tube, to serve as the electronics housing. The lens will face straight up at the ceiling. On the side of the housing will be a power switch and three knobs for red, green, and blue intensity levels.
I've built a few led flashlights before, and this shouldn't be too complex, but it's still a little over my head, and I want your advice on the best way to go about it. Should I use multicolor leds, or individual red, green and blue leds? Power supply concerns? Can I do this easily enough with basic components or should I just say fuck it and go arduino?

I'm going have my own apartament soon, and I'll be going for a retro-on-high tech style.
For example: some nice PC and peripherals, monitors, nice headphones, and some oldish keyboard (like in this pic I took from /g).
A music room with recording devices, a computer, nice audio, a little midi keyboard and a violin.
Some cool TV set, a home theatre would be nice. All set up to play with a NES.
Can I have some advice/recommendations/ideas about this?
Makers gonna make!

Welcome to /diy/, a place to:
Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.
Please keep in mind:
- This is a SFW board. No fleshlights or other sex toys.
- No weapons. That goes to >>>/k/. The workmanship and techniques involved in creating objects which could be used as weapons (e.g., forging steel for a blade, or machining for gunsmithing) may be discussed in /diy/, but discussing the actual use of weapons is disallowed.
- No drugs or drug paraphernalia >>>/global/rules/1. If you want to discuss something that could involve such things (eg carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.
