Sound Activated EL Pocket Inverters (video)

Add a little audio-reactivity to your EL projects! Video on YouTube and Vimeo.

Window-179

EL Wire 6V Sound Activated Pocket Inverter. A small, portable inverter for EL wire with an audio input! This inverter has a little microphone and will light the connected EL according to the surrounding audio volume. Makes for an easy reactive project.

Window-1-104

This inverter requires 6V input (it works great with our 4xAA battery holder) and it can drive 2-3 meters (7 to 10 feet) of our high-brightness EL wire OR 1 meter (3 feet) of EL tape OR a 10cmx10cm piece of EL panel continuously for about 21 hours (off of 4xAAs).

Window-2-60

There is a switch for selecting steady/sound/off modes – steady is always on. Comes with a single 2.5mm pitch female JST connectors, standard for all the EL wire and tape we carry. Theres also two power wires, youll need to connect these to a 6VDC power source.

You can plug any of our EL wire/tape into this inverter directly. To connect a raw piece EL wire to this, youll want a male connector wire

The EL inverter requires a load to stabilize itself. Do not run the inverter without at least 2 ft of EL wire attached! Otherwise the inverter can spike and damage itself

Like all inverters weve used, the 2000 Hz oscillation is slightly audible. To reduce the squeaking, we suggest opening up the case padding it with thick foam tape/weatherstripping. Squirting some hot glue around the capacitors may also help. We managed to get it silent this way.

Check out our EL TRON bag tutorial for ideas, as well as the EL wire couch video!

Soldering to raw EL wire is a little tricky but luckily we wrote a detailed step-by-step tutorial! The tutorial also covers a lot of information about EL and how it works.

NEW PRODUCT – Large Lithium Ion Polymer Battery – 2700mAh

Lipo2700 Lrg

NEW PRODUCT – Large Lithium Ion Polymer Battery – 2700mAh. Lithium ion polymer (also known as ‘lipo’ or ‘lipoly’) batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 2700mAh for a total of about 10 Wh. If you need a smaller battery, we also have a 1300mAh model

The batteries come pre-attached with a genuine 2-pin JST-PH connector as shown and include the necessary protection circuitry. Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly.

The included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at 3.0V. It will also protect against output shorts. However, even with this protection it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 1200mA or less.

Like most lipos, the batteries we sell do not have thermistors built in. This is why we suggest charging at 1/2C or even less – 1200mA max in this case. Even 500mA is a good charge rate, which is how much you can get from a USB port.

Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger! Also, do not abuse these batteries, do not short, bend, crush or puncture. As with all Lithium ion polymer batteries and with any power source – they should be used by experts who are comfortable working with power supplies.

  • Weight: 52g
  • Size: 2″ x 2.55″ x 0.30″ (51mm x 65mm x 8mm)
  • Output: 2700mAh at 3.7V nominal
  • Datasheet coming soon, but for general battery specifications, see the (1200mAh version) Datasheet

UPDATED PRODUCT! Medium Lithium Ion Polymer Battery – 1300mAh. Lithium ion polymer (also known as ‘lipo’ or ‘lipoly’) batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 1300mAh for a total of about 4.8 Wh. If you need a larger battery, we also have a 2700mAh model
