Get flash to fully experience Pearltrees
This neat trick came across on an internal alias. I hadn't seen this before, but I'm guessing it isn't new. Pretty handy for notetaking (if you're a plain text sort of guy/gal).
November 3rd, 2009 This past spring Daniel and I went on a road trip from San Francisco to the Grand Canyon. Along the way we stopped at Chateau Julien for a wine tasting. I wanted to do something with the empty bottle instead of throwing it in the recycling bin. So here it is! You’ll need:
Depending on the type of printer, there are two types of reset or Disable ink level. For Canon MP-450, MP-170, MP-150, IP-2200 IP-1600: Hold down the ” paper “or” cancel “(triangle surrounded by a red circle) for 3 to 4 seconds until the light stops flashing. Repeat this process by staying at least 15 seconds on the same button.
All great websites have a great server behind them. In this tutorial, I’ll show you how to set up a dedicated web server (with Apache, MySQL, and PHP) using that old computer you have lying around the house and some free software. 1. A Quick Overview In this tutorial, we are aiming to accomplish several things: We’re going to install the Ubuntu Server operating system.
How To Boot From A USB Flash Drive For starters this is still a developing science and most people have had good luck with at least one of these methods. Note that flash drives are often also called thumb drives, keychain drives, pendrives, etc. A FEW THINGS YOU NEED TO CONSIDER IN ADVANCE. 1. The PC has to support booting from a USB flash/pen/key drive. There may be anywhere from 0-3 items to change in the BIOS to make this possible assuming your BIOS supports it.
Image from Wikihow What do college students use more than internet and beer? Now you can combine the powers of these two great inventions to improve the Wi-Fi signal in your apartment or dorm. Wikihow has the plans for a beer can antenna booster (although I can’t imagine it wouldn’t work with a soda can too), and it looks awesome. Basically you’ll need to cut open the can to resemble a simple satellite dish, and place your router’s antenna through the hole in the top. The design is undoubtedly directional, and probably wouldn’t work very well if you were lucky enough to place your router in the middle of an apartment. If it’s hidden away in the corner however, or you just want to boost the signal temporarily in a specific direction, there’s no reason not to give it a try.
Before going any further, read the document I've attached to this step, "A Day in the Life of a Flux Reversal" by Count Zero. This document is pretty much the bible on how magnetic stripes work, and you need to understand how data is encoded on to them and the basic formatting of the tracks on a given magnetic stripe card. I'm going to go get a cup of coffee; have it read by the time I get back. Finished?
The electromagnet. I haven't counted the number of turns or dimensions or anything. I passed the 30 gauge enamel coated magnet wire back and forth over the stainless steel shim about 7 times, or until "it looks powerful enough". Looking at how much is left on my roll, I used about 25 feet of wire on the shim, which is a T shape 3/16" wide at its narrowest, then expanding to 1/2" at the end, by 2 1/2" total length.
Two Wavebubbles. Left is an earlier revision with the top removed and with external antennas. Right is v1.0 with internal antennas, fit into a pack of cigarettes. This website details the design and construction Wave Bubble: a self-tuning, wide-bandwidth portable RF jammer. The device is lightweight and small for easy camouflaging: it is the size of a pack of cigarettes. An internal lithium-ion battery provides up to 2 hours of jamming (two bands, such as cell) or 4 hours (single band, such as cordless phone, GPS, WiFi, bluetooth, etc).
I tried holding cancel and the solution given above but it doesn't seem to work for me. I have a Canon MX310, and I recently got a refilled colour cartridge, to find the driver doesn't just say it's empty, it says it doesn't recognise the cartridge, when the model is exactly right (CL-41 FINE). The error I get now is: "CHECK INK U051 BLK COL" then changing to "CHECK INK U051 COL" when it realises the black one is fine, as it was installed new, and is just nearly empty. This is as far as I got into the steps you suggested: 1. Disconnect the power cable. 2. Hold down "On/Off" button. 3.
In the November 1999 issue of EPE (Everyday Practical Electronics), a small and intriguing circuit was published in the Ingenuity Unlimited section by Z. Kaparnik. It was a very small implementation of a typical transformer feedback single transistor invertor. The transformer was a standard ferrite bead with two windings wound on it and the circuit was using the high voltage pulse generated when the transistor turns off to light an LED from a single 1.5V battery.
So I wasn't completely honest - I have used LEDs once or twice before for simple applications, but I never really knew what I was doing, and since so many projects on instructables use LEDs, I thought I might as well teach myself and post about it too. I know that there are many projects already posted that contain information about how to wire LEDs for simple projects - LED Throwies , LED Beginner Project: Part 2 and 9v LED flashlight - teh best evarrr! , but I think that there could still be some use for a detailed step by step explanation about the basics of LEDs for anyone who could use it.
