Ionocom has worked on a wide variety of projects ranging from military battery systems to guitar pre-amplifiers. Shown below is a selection of representative projects.
These projects are examples of consumer electronics products such as computer mice, keyboards and iPod accessories.
This keyboard encoder was designed for a miniature keyboard
for use with Palm and PocketPC PDAs, using an IrDA infrared link
between keyboard and PDA.
Important characteristics are small size, very low power consumption
for long term operation from a single AA cell, and low manufacturing cost.
Ionocom designed the electronics and worked
closely with other companies providing industrial design and software
development.
This consumer product was manufactured offshore in very high volumes.
This printed circuit assembly incorporates a laser-based motion sensor
and a 2.4GHz wireless link to form the basis of a laser wireless USB
computer mouse. Ionocom designed the hardware and wrote the firmware.
The design achieves good wireless range with a
low-cost printed circuit antenna, and achieves good battery life
despite the demands of the laser sensor.
This FM transmitter operates in the 88-108MHz broadcast band
and allows audio from an iPod to be received by a domestic or
car radio.
A novel feature of the design is the use of the display of the iPod
itself to provide the user interface, avoiding the need for a separate LCD.
This, and the compact PCB layout, provided the client with the smallest
device on the market, perfectly complementing the iPod nano.
This consumer product was designed for low-cost, high volume offshore
manufacture.
This FM transmitter operates in the 88-108MHz broadcast band
and allows audio from an iPod to be received by a car radio. It

configured in various different ways allowing the client to produce
a family of products with different feature sets.
Ionocom designed enhancements to an existing iPod speaker/dock product
to add an FM radio tuner, user interface features on the display of
the iPod itself, and an infrared remote control
(the printed circuit board for the remote control is shown here).
Ionocom designed the circuit additions and wrote the firmware.
The enhancements allowed to client to refresh the product with
valuable new features whilst keeping costs low.
These projects are examples of professional and prosumer audio products.
This pre-amplifier for a new electric guitar pickup was developed
to provide new blending and switching features.
The design solved several electrical and mechanical problems,
allowing the client to expand his product range with a unit
attractive to top musicians.
Ionocom's analog design experience produced a design that
"sounds good" whilst keeping complexity down.
This hexaphonic pre-amplifier for piezo-electric guitar pickups
provides six independent outputs, one for each string, and allows
the guitar to be connected to an external MIDI converter or
a sophisticated sound processor. The unit also provides blending
& switching features and integrates with the client's existing
pre-amplifier, producing a solution that is significantly cheaper
than competitive units.
Whereas the two previous piezo-electric guitar pickup pre-amplifier boards
were designed for a retail application, these printed circuit assemblies were
designed to incorporate the same functionality in a form-factor suitable
for use in a factory-fit application. This allowed Ionocom's client to sell
to both retail and OEM customers.
Using custom stacked pots this parametric tone control for
piezo-electric guitar pickups provides bass, treble and
sweepable mid-range controls in addition to volume adjustment
for analog and MIDI signals.
These projects are examples of professional products including some form of wireless communication.
This miniature transmitter was designed for an asset tracking application.
The unit includes a fully synthesised transmitter and a microcontroller.
Transmitting into a built-in loop antenna the unit operates on two channels
around 433MHz, and was designed to meet both FCC and European regulatory standards.
Important characteristics for the client were long battery life and small size.
This ultra-miniature 433MHz receiver was designed to fit inside the battery pack of
a consumer cell-phone, to add proprietary features without enlarging the form-factor.
It measures just 40mm x 50mm and is less than 3mm thick, including the antenna and screening can.
Designed to meet FCC and European standards, the board consumes minimal current
and interfaces with custom software running in the phone.
This miniature 433MHz, dual channel receiver was designed to meet both FCC and
European regulatory standards. Using one-third the current and occupying significantly
less volume than a previous single channel product, the dual channel receiver doubles
the probability of receiving a transmission.
This printed circuit assembly is the heart of a microprocessor-based desktop unit
that includes a radio receiver, large amounts of Flash memory for storage of events,
a telephone modem for communication with a central office, provision for connection
of an internal cellular modem, and both mains and battery power supplies.

client's previous design. The unit was designed to meet
international safety standards.
This printed circuit assembly incorporates an off-the-shelf cellular modem
module together with a custom switched-mode power supply and a tri-band
(900MHz, 1800MHz, 1900MHz) antenna. The unit provides communications over
CDMA or GSM cellular networks. Ionocom selected the modem module and antenna,
designed the power supply electronics,
and optimised the antenna matching through careful positioning in the enclosure.
This interface board allowed an Iridium satellite communications module to be
added to a desktop communications unit that had previously only supported
PSTN and cellular phone communications. To meet the client's tight deadline
Ionocom took this product from requirement to working prototype in just two weeks.
This handheld device includes a 433MHz transceiver for communicating with asset tags,
a 2.4GHz Bluetooth transceiver for communicating with a Windows Mobile handheld,
and a 13.56MHz near-field inductive link. Ionocom designed the electronics and the
mechanics, including tuning of the antennas in the enclosure. Designed to meet FCC and
European standards (not easy with three co-sited radios), the device is significantly
more robust than the client's previous design.
