boot a linux live cd and pick out all the usblib files from windows and let it freak out next boot?

dollar stores FTW

dollar tree had a huge assortment of usb cables and high output white led products.. ok so the loot

Usb A to B

Usb A to mini A

3 3inch translucent enclosures with 3 ultra-bright white led's and driver each (mini tap lights)

new earbuds for my psp (slightly less crappy than the 3$ colby brand)

and a cat toy -ball with a US quarter sized pcb containing R G and B ultra-bright , large smd led's ... thinking with a razor knife and a pingpong ball could make a cool (controlled) display

5$ + tax

[edit]oops and a 5 pack of crappy lighters 6$ + tax[/edit]

OK what is K-mart thinking, I can understanding having a multimeter selection but honestly, this is borderline lunacy

yea let me grab that along with some cat litter, mouthwash and batteries, hm drat never mind put it on layaway please

My personal favorite are these cheapos:

see those are the ones I like to call toys, they break every time I look at them funny, BUT for 2.99 that is just fine

the 24.99 they ask for them at wallmart can right up go ! itself

the second one you have linked is available as a craftsman with a few more ranges  @ 30 bucks

Hello, when I was a teen I was really into electronics, having blown through 2 el-crappyo "yellow box" multimeters due to bad plastics my dad got me a pretty darn nice for the time multimeter for xmas or birthday (I forget  :-[)

so for darn near 15 years I have had a Triplett model 2202, sadly to say finally the plastics are failing, and the probes no longer sit securely in their sockets causing all sorts of headaches, its time for a new meter

for the record I have not tossed the 2202 in the bin yet, since it is still fully functional electrically I am seriously thinking about doing a case transplant / mod to make it a compact desktop unit


Since I have a almost non existent toy budget, and overall cheapass I shop around for the best quality + biggest bang for the smallest buck. Also being around more newbie oriented forums such as this, I try to think simple and accessible. For our United States viewers I often recommend the Craftsman 82141, And , 'putting my money where my mouth is', that is what I bought

Craftsman is of course sold at Sears, but also in limited selection from K-Mart, on K-Marts website they have a fairly decent selection of different packages, the 82141 seems to be best suited for small electronics for under 20 bucks. It cost 19.99 + tax, and there is a free site to store option .. BUT I have bounced around a few different K-Marts in the area and they all seem to carry the 82141, along with a 25$ model  (which has less features but comes with a ac probe, obviously a electricians package)

Note: You will not find this item in the Craftsman section of K-mart!!!

Whoever though this up was really bright, In the few K-Marts I visited, back in the home improvement section there is a WALL of craftsman tools, its OBVIOUS, paint job, banners, and all! So where do you find the multimeter in your local K-Mart? Around the corner by the extension cords  :smiley

Anyway Its a nice unit in a "rubber" boot, in the boot its just a shade smaller than what I had, outside of the boot it is a shade larger than what would have passed as a pocket multimeter not too long ago.

It comes with a nice set of probes, simple but fully explanatory manual both in English and Spanish. Its sturdy made of reasonably thick ABS plastic, the boot is extremely thick stiff rubber, and has a nylon kickstand on the back for desktop use. One pet peeve is that it does not come with a battery, nor specify on the package what it needs., but its just a single 9v battery like most multimeters

feature comparison, keeping in mind a 15 year old EE student model VS a 20$ K-Mart model

]
|  Triplett 2202| Crafstman 82141  


ac / dc amps|  200ua scale to 10a MAX|  200ma scale or 10a MAX
VDC|  200mV scale to 1000V MAX|  200mV scale to 600V MAX
transistor function|  npn/pnp tester and hfe |  none
resistance|  200ohm scale to 20Mohm|  200ohm scale to 2Mohm
Display|  1 inch lcd +-1999 count|  0.5 inch lcd +- 1999 count

what the Craftsman is lacking is really not that big of a deal, my old 2202 was really floaty and inaccurate in the micro-amps range, voltages are fair enough, and while 20meg ohm is nice to be able to read, it does not come up that much

The transistor functions of the old model can be quite useful, but not so much in digital, the verdict?

Kmart / Craftsman model 82141: grade A for under 20$

not the best ever made, but not a toy, nor a cheap kit, a rubberized tough good quality multimeter that meets most requirements for hobby level electronics for under (by a penny I know) 20$ and with care can last you at least 15 years of fairly constant use

he has acrylic washers

course if he didn't multipost we would all be on the same page

that's a bad Mowcius  ;D

Or just for random places where the piano closes etc.

Mowcius

we have a winner, they are just rubber bumpers to keep parts from banging against eachother when you open and close them (ie lid or fallboard)

Quote
I presume they are some kind of rubber foot type thing for stopping the piano keys. What they bump onto when you press them down or something but I thought they were felt.

those are dampers, they are made out of wood wire and felt, the felt is what sits on the strings to keep them from vibrating, either cause you want them to or because of sympathetic harmonics

[edit]oops my bad, you said UNDER the keys yes those are paper and felt also[/edit]

the "textile" stuff under the feet of a piano?


no that really could be anything from scraps of carpet to specially designed cups to protect hardwood floors

Good Lord...For what?

Lots of pianos?  Grin

yep (bout 300,000 sq feet of them double stacked)

check your local home store, they sell caps that are attached to a loop, so you can run a screw trough it then snap the cap on top

alternatively piano bumpers, they do not glue on but rather get shoved into a hole, and I might know where to get some (actually i just received about 85lbs of them today)

its not impossible, its just YOU need to cover your butt

ask around the local electronics wd's (warehouse distributor) see if they or their sales reps would be interested to help a hobby group, part of that help might be funding for legal consulting, which is generally not that expensive in comparison to someone chopping off a thumb in your barn on beer + ps3 is bricked night

if someone on your property gets harmed then its generally your problem

lets say someone grabs the wrong end of a soldering iron, and has severe burns, causing them to miss work etc

a) did you get them to sign a release form?
if not, who would you rather pay them, you or your insurance
