Transtronics offers a wide variety of design capabilities to get your product out-the-door. We can take your product design through the following stages:

We include embedded microprocessor control design as part of our specialization in analog and sensor circuitry with experience in the following areas:

The following list of projects will give you a feel for the full range of capabilities we have in house.

Projects

Non contact Temperature controller: this project incorporated IR temperature sensing, IR motion sensing, and IR bi-directional data communication with an embedded microprocessor for the HVAC industry.

Cell phone telemetry system: Fixed a project another company abandoned - debugged a telemetry system and corrected C code to fix a MODEM problem.

Video toaster (desktop video): We contributed to this project - a computerized video effects generator (Product won a technical Emmy award). Work included part of circuit design team, PCB art work. Training of others in CAD usage.

Video Flyer : Non linear video editing system. Work included design debugging, software management, and team leader.

Digi-view and Digi-view gold: Low cost video digitizer. Worked on synch strip circuit design, PCB artwork, production and testing. In the gold model, we also designed in an onboard switching power-supply.

Gender-bender : A switching power supply in a gender changer. Work included circuit design, PCB artwork, and packaging.

12V high-pressure sodium lamp, solid state ballast: Featured switching power supply, high voltage start circuit. Work included circuit design, PCB artwork.

Programmable F/V converter: Interface product for water industry used to convert pulse type flow out puts to voltage, 6805 assembler programming, production and testing.

Battery drop out relay: A device for disconnecting lead acid cells from load at end of use voltage - went to production 100,000's sold. Work included circuit design, PCB artwork, production, testing.

Tone card RTU unit: A Remote control unit that works over radio links to control water systems. Featured a very low cost, 120VAC I/O, radio modem.

Two-wire controller for water systems: Featured self-adjusting calibration, lightening resistance. Work included circuit design, PCB artwork, production, testing, and field support

Line filter : Featured three stage transient filter for one of the worst lightening environments. Work included circuit design, PCB artwork, production, testing and field support

Microwave chamber proportional temperature controller: Featured derivative feedback control (PID loop). Work included circuit design, PCB artwork, production, testing, and field support

Microwave (Gunplexer) transmission subtractor : This device removed transmission signal from reception., PCB art work.

RS232 radio modem : Featured switched cap filters, narrow audio bandwidth. Work included circuit design, PCB artwork, production, testing, and field support.

FM mode RTTY decoder : Featured switched cap filter, IF interface, offset tracking. Work included circuit design.

Diaper Wetting Alarm: This is a very low cost alarm for training bed-wetter's that sounds a buzzer when they get wet!

Radio Tower lighting alarm : Featured self-calibration, toridal sensors, low cost. Circuit design, PCB artwork, production, testing.

424 machine : Automation project that changed a box slotting machine to do multi-revolution length slotting. Work included circuit design, PLC programming, testing.

323 Machine : Automation project that uses a PLC to control a waste cardboard bailer. Work included circuit design, PLC, programming, testing.

ESD detector : Device used in ESD training. A photo detected gas discharge tube. Work included circuit design, production, testing

Encapsulation: Designed molds and procedure for cost effective encapsulation of electronic modules using vacuum de-bubbling.

Temperature gradient display: This box showed off a fan speed controller by moving its thermistor sensor back and forth over a rod that is hot on one end (via a PTC heater) and cold on the other (via a Peltier cooler). Used Hall effect limits, lead screw actuator. Designed PCB mechanics, and case. Start to finish in 3 weeks.

Token Verifier: This project used a flux gate to detect a mu metal tag within a token. Work included PCB modifications, 6805 machine code changes, and additions.

Multi Sensor Smoke alarms: Produced a prototype that used an optical detector to sense smoke, a CO detector, and heat sensors

Sensor lightning Consultation: Helped Nellcor Puritan Bennett with damage to pressure transducers caused by lightning transients.

Built first computer in 1980.
