Yellow Jacket backup battery case/stun gun for iPhone 4/4S and soon iPhone 5/5S

Yellow Jacket3

Now there’s protection for your phone AND you with the Yellow Jacket rechargeable backup battery case /stun gun. This case comes with a removable stun gun pack and provides protection for your iPhone 5/5S using TPE soft plastic (PC/ABS hard plastic on the iPhone 4/4S case) and doubles the life of your phone’s battery (1800mAh).  The iPhone 5/5S stun gun case has dual push triggers which allow you to activate the stun gun with either hand and deliver 950,000 volts at 1.3mA to an attacker (650,000 volts with the 4/4S case). The Yellow Jacket case has a swiveling electrode cap and a safety switch to prevent accidental discharge and measures 5.6″ x 2.6″ x 1″.

It should be pointed out that this stun gun is not a taser. A taser will launch probes that attach to an attacker then deliver electric current at a higher amperage than a stun gun and will incapacitate the attacker via loss of muscle control. The Yellow Jacket stun gun case is a direct contact weapon. It does not eject its electrodes and it delivers electric current at a much reduced amperage (1.3 mA or less) which creates a short burst of pain when the electrodes come into contact with an attacker.

The Yellow Jacket iPhone 4/4S case is available through Amazon for $99 in black, pink, white, and yellow and the iPhone 5/5S case is available for preorder from Yellow Jacket online for $149.99.

FINIS Neptune – an updated waterproof MP3 player with Bone Conduction audio transmission


Like most of you out there, I don’t jump out of bed in the morning saying to myself “YES! I’m going to go and do a grueling workout RIGHT NOW!!” I need music to motivate me. So do swimmers. The Gadgeteer has reported on various waterproof music gadgets in the past like the FINIS swiMP3v2 and the FINIS swiMP3.1G waterproof MP3 players. The FINIS Neptune is an updated version of those devices and appears to have made a few improvements on them. The Neptune is made up of three pieces (instead of two) all of which attach to your goggles: two speakers that rest against your cheek bones and the player that rests against that back of your head. The player has an OLED screen from which you can view and scroll through your the audio files and it supports the most popular file formats like AAC, MP3, and WMA. There is also a greater amount of storage space (4GB) for your music, audio books and podcasts. The Neptune, like the swiMP3 models, is waterproof up to three meters, works using Bone Conduction audio which transmits sound waves through your cheek bones directly to your inner ear, and you still upload and charge your unit via a USB cable. The FINIS Neptune sells on Amazon for $107.53. Okay folks, no more excuses! Let your music motivate you and encourage you to work out longer, harder and faster!

Gadgeteer: Show us your desk series – Kathleen


I know that this is a series about each of the Gadgeteer members’ desks and what things we use to do our work, but since I have just started as a Gadgeteer, I will also show you where I do my homeschool teaching. To begin with, science and technology are in my blood, but so is frugality. I’m at constant war with myself because there are many gadgets I would love to buy, but it has to be within our budget. As it is, here is our very basic office. My husband and I share this desk which is made of solid natural cherry and was our biggest office expense, but I love it! We have just upgraded our computer to an Dell Inspiron 3847 PC where I will most likely do all of my Gadgeteer work. We will also be transitioning to a wireless mouse and keyboard (wires drive me crazy!!), but for now my USB Dell mouse and keyboard do the job. I haven’t yet established just where my photo studio will be or what tools I will use to do my photography work for the Gadgeteer, so there is nothing to show you on that front. Right now, I am using a Canon point and shoot but will be upgrading to a mirrorless digital camera soon.  Read More →

The toothbrush has entered the 21st century

Oral-B SmartSeries 1

Oral-B has created the SmartSeries toothbrush with Bluetooth 4.0 connectivity and associated iOS and Android apps. Now brushing your teeth will no longer be such a mundane task! In addition to making brushing more interesting and potentially more enjoyable, this toothbrush was developed to help improve oral health by collecting and reporting data on your brushing habits. Each brushing session will activate a timer in the app and will provide a quadrant guide to instruct you when to move to another area. This allows you to focus on the problem areas identified by your dentist. It will even notify you when you are brushing too hard. Your brushing performance and achievements are tracked and reported to you to encourage your progress. Not only does it collect data, but it also allows you or your dentist to program the toothbrush for brushing time and select brushing modes. This toothbrush is projected to cost around $200-$300 according to different sources and will be available in June 2014. The iOS and Android apps will be available in May and August 2014, respectively. Ah yes, “everything is better with Bluetooth.”

REAL piano sound for your mini Mozart


Do you remember that toy piano you used to play when you were five years old?  It might have looked like the real thing (except for the color), but the sound completely missed the mark. Korg has updated this toy favorite with REAL piano sound in its new product, the tinyPIANO. This 25-note (2 octave) miniature upright digital toy piano reproduces the tone quality of a sampled grand piano. It is made of wood which makes it sturdy and has minimal moving parts to ensure safety. Additionally, for all you parents out there concerned about a never-ending cacophonous blast of “music”, the volume has been adjusted to a modest level appropriate for you and your child, and the piano allows the use of headphones (although the output is monaural). It has 50 recorded demo songs and 25 built-in sounds like electric piano, organ, marimba and steel drum as well as the toy piano sound, just in case you’re the nostalgic type. It measures approximately 15 x 10 x 11 inches and weighs about 10 pounds. The piano runs on six AA batteries which allows you to set it up anywhere, but an AC adapter is also available as an optional feature. It comes in four colors (black, white, red and pink) and is available for $250 as a pre-order through Kraft Music online or Amazon for $239.28 plus about $100 shipping to receive it from Japan.
