Buy Joe Knows Electronics 1/4W 86 Value 860 Piece Resistor Kit

Customer Ratings:

This set of resistors is the perfect starter kit for any electronics hobbyist. Even an avid tinkerer/engineer will find this price near impossible to beat. At about $20, you have practically all necessary resistors neatly organized into bags in a small, space saving, box. My only wish is that they start providing higher wattage sets!

----

Update:

I've been running into tolerance issues with these resistors. Here's an example: A 680k resistor reading at 734k. On the high-side of 1%, this resistor should be reading at 687k. Now if the product stated 10% tolerance, we'd be alright.

I'm also not a fan of how flimsy the leads are coming from the resistor. Looks like the adage "too good to be true" may hold weight here.

----

Update:

I've gone through the tedious task of measuring each of the 86 values in this set and here are my results:

470 ohm 2% variance

1.5k ohm 2% variance

100k ohm 2% variance

270k ohm 2% variance

470k ohm 3% variance

330k ohm 10% variance

680k ohm 10% variance

5.6M ohm 30% variance (only one of the resistors read this high, the others hit 1% as expected)

The 2% variance, while out of spec, shouldn't be a concern. The 330k and 680k, however, are way off. One of the 5.6M resistors read a whopping 30% off. I'm wondering if there's quality control issues from this batch.

Joe has offered to replace the sets that are out of range. I appreciate this greatly. It is more important to me in dealing with a business to see that the business cares about its product than getting a faulty item. In this case, I'd like to see the new batch arrive with the thicker leads as promised and with greater QC. Also, again, higher wattage sets!

This resistor kit is a good value for the electronics hobbyist. I looked at several electronics catalogs and hobby sites before ordering this item. The kit provides a great range of precision(1%, metal film)1resistors in a convenient and well marked package. The 1/4 watt rating is fine for most digital and many analog projects. I prefer this box with individually labeled resealable bags to a cabinet of resistors because it takes less space. The resistors are small, so the color code markings can be a bit hard to read. If, like me, your eyesight is not perfect, a multimeter is a useful way to confirm the R value.

the package has resistors from 0 Ohms to 10M ohms with accuracy 1%, .25 Watts rating , good enough for most of the work you might need. cheap price, high accuracy good deal.

Honest reviews on Joe Knows Electronics 1/4W 86 Value 860 Piece Resistor Kit

I'm colorblind. I work and tinker with electronics, and it is often difficult for me to discern the color bands printed on through-hole resistors. Many resistor kits do not individually label resistors, and expect the user to sort them. It is very nice that this kit individually labels each bag of resistors!

I got this kit because I've recently become interested in electronics. One day I realized that the little selection of resistors that I got at RadioShack didn't cut it.

This kit is so incredibly convenient. The first thing that I did when I got it was to sort my existing collection of resistors into the bags. They are labeled with the value, so this was really easy.

Some things you should know about these resistors:

* They are the "blue" kind. Not necessarily a bad thing, but it does it make it a little more difficult to read the color codes because the blue background provides less contrast.

* They are 5-band resistors. The box has a great little chart for reading 5-band resistors. If you can read 4-band resistors then you will have no trouble with these. Why was this necessary? Some of the resistors have values that can't be expressed using the 4-band system.

* The leads are just a little bit thinner than you would find on a resistor that you bought from RadioShack, or a similar store. I personally don't care. They are still 1/4 of a watt, but the leads aren't as thick as the resistors that most beginners have become accustomed to.

I highly suggest that you buy this kit. If you ever need to build an oscillator, it will be important to have the right resistor values. Same goes for voltage dividers.

With that said, I have two suggestions for future versions of the kit:

* Please include some empty bags with blank labels so that we can make our own bags if we have some strange resistor values that didn't come with the kit.

* Please include 29k resistors. They are important if you wanted to make a phase-shift oscillator (search for it on Wikipedia)

P.S.: Joe, if you ever make a capacitor kit that matches the quality of this one, I will buy it in a heartbeat.

Best Spy Gear Micro Spy Kit X-2 Deals

Customer Ratings:

My 8 year old had some birthday money left over and suggested we do some research on the internet for spy gear. After an exhaustive search he decided on the micro kit. He was not disappointed. Everything worked right out of the box with the exception of the motion detector which needs 4 triple A batteries and a small phillips head screwdriver. The best tool is the night spyer as the magnification works very well and the red spotlight is cool looking. The motion detector is a little too sensitive as it went off without much (and sometimes nil) motion. But better to be too sensitive then not to work at all. The spy listener worked well also as my son stood in his room and whispered and I could hear him perfectly. Without the spy ear I could not make out a word he said. The voice scrambler was very cool also. Although the sound is tinny it doesn't really matter as you use it to alter your voice anyhow (it also alters the speed of what you say). The belt holds everything conveniently and clips securely. Is it durable? If you throw it around or step on it, it won't last long. But with some care it should last. I didn't feel that it was shoddily made. If you consider that you get 4 really great spy tools it is definitely worth the money. Your child will not be unhappy.

This belt kit brings together 4 toys that are in other package deals or available separately, but at a better price here. And the waist belt is really nice, with a special slot clip for each item; it is adjustable and is a nice durable nylon webbing material. We have had no problems with it or the belt clip. You can also wear the belt over your shoulder like a bandolier, and it look really cool to the kids that way. You can see separate reviews at Amazon on each of the separate 4 toys that are on this belt. They are the Micro Voice Scrambler, Nightspyer night Mini-Scope, Spy Motion Alarm and Micro Listener, and I have to tell you this belt gives Batman's utility belt a run for it's money. A reviewer had problems with the motion detector, but ours has worked really well over the last year.

The "Micro Voice Scrambler" is one of the kids favorites, it is great for playing on the phone, or just goofing off with each other and it is nice to hear them laughing so hard while they play with its settings. It not only changes the tone, but the speed of the voice so you can sound deep and slow like Darth Vader, a robot voice, or a baby voice, or the chipmunks high speed voice. The "Spy Motion Alarm" works good, it can be placed anywhere you need an audible alarm to let you know if the enemy is coming. The battery lasts a long time, and a tiny red LED on one side lets you know if it is on. It has a range of about 20 feet for detecting motion. The spy micro listener allows you to hear footsteps and whispers over 30 feet away. The "Nightspyer night Mini-Scope" is basically a set of mini-binoculars with a hidden pop-up flashlight. This toy is the weakest of the 4, and is more for pretend action than anything else. The other 3 actually do what they say and are very worthy little gadgets.

The toys are durale and none have broken in the year we have had it. Spy Gear sells other toys like the Micro Scope that have their own clip built in, and so you could add it to this belt. All of these are great fun for hours of spy play, camping, or just backyard fun and the price is right.

I got this toy about a year ago at a target. It is so much fun because it has a cool belt that you can wear instead of having to carry around all 4 devices.

I rated the fun of the toy only 4 stars because I can't seem to find all the devices. I think that is just my problem.

I rated the toy's educational value 2 stars because it taught me nothing except to buy more spy gear.

I rated the durability of the toy 5 stars because it is very durable.

I rated the toys overall category 5 stars because it is a lot of fun when I have all 4 devices together.

Now I am going to tell you about all of the devices.

The MOTION SENSOR is my personal favorite because I can see if anybody is entering the room I am working in. The only thing I don't like about it is that it is that it is very loud. Somebody will know you are in there by the noise. I wish it just lighted up!

The VOICE SCRAMBLER is a basic recorder except that you can move a lever and your voice is scrambled.

The SONIC EAR is a thing that magnifies the sound into the headset.

The LASER BINOCHULAR is the dummest and last thing in the set. It has a fake laser and it has binochulars built into it (with only one view hole).

The SPY BELT is the most conveniant thing. It has a compartment

for each device.

Overall, it is an awesome toy! If you take my advice, you will leave this computer wanting this toy.

Honest reviews on Spy Gear Micro Spy Kit X-2

This toy is great! The NIGHT SPYER really works well. It can see in even the darkest places. The detector is nice and sensetive [and loud....], and it sounds even when there is a little bit of light. The voice changer lowers your voice, but besides that, it works great. The listener is the best thing in the micro kit. You can hear voices from REALLY far away, and through walls. The durability of this toy is ......ok, but it won't last long if stepped on or dropped. The educational value is bad because there is nothing educational. But it is SO MUCH FUN! Buy this toy! You won't be dissapointed!

We are going on almost a year of having this spy kit, and my two boys are still playing with them. It is a hit with all their friends.

The voice scrambler is the best of the gadgets. It really works. The motion detector has also gotten a lot of use.

The only gadget we have had troubles with is the listener. The kids have to remember to turn it off. If you forget and accidently leave it on for a day, the batteries are dead.

Anyway, this is definately a kit that gives you your money's worth of play. I'm glad I bought it.

Discount Live Butterfly Kit: SHIPPED WITH 10 Painted Lady Caterpillars Now

Customer Ratings:

We got this earlier this Spring, I decided not to review until our butterflies were released. Our three year old was amazed watching the caterpillars eat inside the small containers. All arrived alive, but two out of ten died later. The eight left did turn into cocoons right before our eyes three weeks later. I carefully placed them into the butterfly container, on the side using the hook on the paper backing as instructed. All eight turned into butterflies in three to four weeks after that. Then as a family we released them by the wild growing raspberry bush near our apartment. Our daughter was sad, yet also happy to watch them fly away. Every now and then throughout Spring we saw them in the trees right where we released them.

I purchased this because my daughter (3) loves Disney princesses. While it held her attention for a while, the games are very disappointing. There are only three games with two settings, but no real teaching variety. The games center on point and click, arrow buttons, and keyboard familiarity something the basic console teaches.

Overall, very disappointing for $20. Seems the game makers may just be relying on the Disney label to sell games I fell for it, but I would not recommend it.

The LeapFrog ClickStart games are not the most exceptional as far as quality of the character resemblence, and none of the games are going to turn your child into an Einstein. But my four year old loves to play them and she is learning to spell from them and learning computer skills. She especially loves anything Disney Princess. Next to the game already downloaded on the product when you buy it, this is the game she likes the most. I try to limit TV time so if I can get ready in the morning and she is doing something interactive/educational I feel it's a bonus.

My daughter is just now getting into Princess mode and she likes this game. I like the game b/c it teaches her a bit more than the other games we own, which are Learning Carnival, and Cars.

The Ariel game on the 1st level teaches arrow key use. Which is also reinforcing right and left concepts. This is the best game so far with teaching arrow key use. She now understands what those keys are for and can play it herself. My daughter is just over 2 1/2 yrs old.

The Cinderella game on the 1st level teaches them to click and "drag" the mouse. This is concept that hasn't been taught on any of the other games. You click the shape and drag it over to the cut out shape in the dress. The game catches it when they get close and puts it in the dress for her. I really like this basic dragging concept and she is learning about where to put missing items. I am very happy with that part. It switches over to designing Cinderella's dress and the game is not very forgiving when it comes to the mouse, you have to be pretty exact. That will be good for her when she gets a little older and more into the age range intended for this toy. So she already has to grow into level 1 a bit. I like that.

The Belle game will be more exciting when she is bigger, also a bonus. On Level 1 you use the arrow keys to catch books. On Level 2 it calls out a letter and you push the letter to catch books. Level 2 is actually easier for my daughter than level 1. This is a reoccuring theme on for us on the Clickstart. My daughter can find letters better than using coordination with the mouse to complete games and finding letters is a Level 2 concept. Odd.

After you complete a game you get a bonus round of clicking on gems before they disappear. They disappear faster on this game then they do on any other of the ones we own. So it will be better for the kids more inside the age range for the Clickstart. Not as good for the newbies.

I like this game a lot. If you have a beginner at this computer and want to purchase a game to go with the Clickstart, I highly recommend this one. Ariel and Flouder talk a lot which gives them a little exciting break in between games.

Honest reviews on Leapfrog Clickstart Educational Software:Disney Princess, The Love

Overall, I'd rate this an average to disappointing experience. There's only three games (plus a song/sound effect generator), and Cinderella's "game" is basically just a drag and drop dress decorator. The little mermaid game is a maze which taught my daughter how to use the cursor keys to move up, down, left and right. The belle game is pretty hard for a young kid, as you have to guide a character using the arrow keys to pick up books that drop from the sky rather quickly.

My three year old enjoys this cart but it only holds her interest for 15 minutes or so. The educational aspects feel thrown in and there isn't much variety. There's quite a difficulty jump from Level 1 to Level 2 as well.

Definitely don't pay full price for this cart, it's just not worth more than $12.

Review of VTECH DISCOVERY NURSERY FARM

Customer Ratings:

We found this toy at a baby consignment store near use slightly used. We got several toys at once and this one is by far my 9 month daughter's favorite! We set it up on our ottoman and she loves to stand up and "play" the piano and dance to the music. I'm pleasantly surprised how many different noises this toy makes and how many different things she can do with it. As a parent I also appreciate the different volume levels, since having an electronic toy can mean a lot of extra noise!

It looks like there's a newer version of this toy out there now, so I'm not sure if this one is around but if you can find one, I'd highly recommend it. New or used it's a great find.

Pros:

Lots of different sounds and music

Colorful and engaging for babies

Lots of buttons to press and things to do

Different volume levels

Reasonable size: big enough that it's pretty sturdy but not so large that it doesn't fit in the toy bin

Cons:

May not be available?

Takes batteries (this is only a con if you're trying to avoid electronics)

I bought this game for my three year old even though the package said it was for a four year old. She is advanced for her age so I thought she would do well with it. Unfortunately she will not let me show her how to use the control. She will play along with me as I play the game but then gets frustrated and wants to try her self and that creates more frustration. I think it will be great for year in about six months or so. The one thing I did not like was that since it was titled V-motion and the package stated it would be more physically interactive I expected just that. Unfortunately it is not as physically interactive as I would have hoped.
