We need a logo for a new company that is developing antennas. We want it simple in neutral colors; maybe the text should...communication signals. These lines could maybe look good if they were of some dark blue or dark red color. The one line that crosses the letters are thought to coincide with the lines in the letters "K" in "LINKS", and "T" and "E" in "ANTENNA". It should not look like the words are "crossed out", but maybe rather give the impression that the line is behind or "inside" the letters. We would also really like the background of the logo to be transparent, so it could fit on the most background images/colors. We are open to any suggestions on the design. We would be really happ...

I have a fairly simple project that I have put together from manufacturers spec sheets and product information. I'm looking for a talented engineer to look it over to find any potential problems and to make suggestions before I send the product to manufacturing. It is a design based around 8-devices Carambola 2 SOC and has a Li-Po charge circuit and simple power distribution, as well as a Ceramic wi-fi antenna. I'll supply my schematics, BOM and links to spec sheets on the components used (3 ICs + the SOC). I created the PCB in Altium, so I could also provide the Altium or Gerber files, if that's of any use.

I 'm working on a project that includes a arduino 1, some sensors and most importantly a solenoid valve (attached link) . This project intend to bring it to a state of production but I need to design a packaging for the entire system which separates the electronics of the valve so that if water comes out of it will not get wet electronics. Modeling should serve to be printed in 3D. Some sensors must be out of the box as soil moisture and temperature . In addition an antenna will be out for the set has gprs connection. Everything must be well sealed because it will be outdoors and must be resistant to rain . Consider that out here will be small solar cells and space for a battery inside Links attached equipment I use

...breakout board/test board for the On Semi AX-SIGFOX SoC chip. You can use the reference design suggested. There is a rough layout from the official development kit here: with further details available after registration (or ask me and I'll send you) This will be used for trials so there aren't many rules. We need at least power and UART broken out into pins and the antenna connection. If you can break out more GPIOs, SPI etc then great. The RF output can go to a PCB edge SMA connector. A bonus would be to add a suitable PCB antenna for 868Mhz such as the one in Texas Instruments Design Note. Please indicate if you're able to do this, it would definitely put you ahead! http://www

We are tracking objects moving through an environment. We have up to 20 RFID antennas (made out of 125khz rfid coils) that objects can pass through. Each object has a unique RFID tag. We need to record every time an object/tag moves through an antenna and record the timestamp and which antenna the object moved through. There are multiple objects (up to 30 unique tags), but it is very unlikely that two pass through the same antenna at precisely the same time. It is ok if the antenna reads from the same tag several times for each pass through, but not tag should be missed. We need sketch + wiring diagram + parts list.

We need to design a enclosure/case but very good looking...similar with a router without antenna, but have something of an apple product finish. I also need consultancy regarding costs since I now nothing about product design/development. We just have an idea in mind, need someone to guide to the right places. Any help appreciated

antenna coupler for 400-410 Mhz through a polycarbonate case to be designed

Dear bijan01in, my Name is Philipp and I´m searching for someone to design a PCB for us, based on some requirements and specifications. The board we want you to design has to be Arduino-compatible (based on the atmega328p from the Arduino Uno R3) and like the Arduino Uno R3 we need a USB-Port for programming and the serial communication. Furthermore we need four relays (5V), switched with the Pins D4 (Relais 1), D5 (Relais 2), D6 (Relais 3) and D7 (Relais 4) from the atmega328p. Each relay should have a red status-LED where we can see whether a relay is activated (LED switched on) or a relay is not activated (LED switched off). The relays should switch 250V and at least 1 A. I saw that the Helishun HLS8L-DC5V-S-C should work very well. What do you think? The NO-Output-...

...header pin jumper to reverse one of the input polarity (from active high to low), > Some indicator LEDs, > A local speaker level control > Voltage reduction circuit to reduce 14.8 volts DC down to about 7.5 to 8volts DC > 1 RJ45 jack for external radio interface > DC input jack > External remote switch input to enable the unit on/off with an external switch using a ground connection. BNC antenna connection and DC input may be mounted in the enclosure and wired to the PCB board. This depends on the enclosure and layout of the components. This would be a small volume project that I would like to have a small PCB board house produce in small quantities. I'm not clear on the procedure to have a PCB board fit into an enclosure. The PCB board would ...

The main objective: to find out what we need to be able to broadcast in the US using long and medium wave (from 100kHz to 1000kHz) with 1 kW transmitter. Questions: 1. how much costs licensing? 2. how long it would take? 3. which documents do we need to pass the licensing procedure? We are looking for someone in the US who understands radio (radio engineering, r...advantage. In the US, the regulator in the field of radio frequencies is You'll have to phone them and if it would be difficult to understand by phone, you should come to the consultation. As a result of a call or consultation - you get answers to our questions. The next stage of cooperation is a long-term contract for the implementation of the project in the US (licensing, antenna construction).

I am looking for someone to help design a solution that would have a mounted directional antenna constantly point either to a pre-designated GPS location or to the strongest directional of a transmitting signal. The mount would have to be motorized as well. Ideally we use off the shelf components (easily ordered via sites like Amazon) and a simple computer system like an Arduino or Raspberry Pi. However I am flexible and I am looking for the best solution on a budget. Some other projects that might provide inspiration, but are not designed for this exact purpose are:

...project and I have decided to implement a shaped antenna that creates a 'fan shape' field. However by shaping the field, it is reducing the read range and so I need to increase the read range of the system x6. To achieve this I think I need to include an an amplification system between the reader and antenna, but I'm not sure how to do this and how to incorporate this into the design. I'm looking to get the electronic design for the amp created, so that I can prototype it then put it into sequence with my existing electronics. Please ask any questions if you need more information! I'm not an electronics expert! :-) Technical specs for the RFID system are: Frequency - 125kHz, Communication mode - Full duplex, Keying - 2kbps,...

I have designed a circuit board...module and two integrated trace antennas on the PCB, designed per manufacturer design recommendations with pads for a "PI" filter for impedance matching the antennas to 50ohm impedance. I'm looking for a RF engineer who can select components (capacitors and inductors) for the PI filter and test the circuit boards with the proper equipment, a network analyzer. In the attached circuit board image, the PI filters are represented by C7, L1, C8 and C9, L2, C10. You'll note there is also a pad to shunt the antenna to a UF.L connector for use with an external antenna, I'm not too concerned about the external antenna. Please only bid if you have the correct equipment and experience with this type of w...

I have the base paper and require a novel problem statement out of that and want to prepare a 2500 word proposal on PhD level. My idea is to design, fabricate, test and measure Microstrip Antenna with Fractal Shape and Electromagnetic Band Gap (EBG)Crystal structure for better performance interms of gain, Bandwith, Radiation pattern, Return loss and other antenna performance parameters. The proposal will be based on gap-coupling and EBG structure. This would ensure that other antenna parameters are taken care of. Then I would also like the use of CST MWS (version 2015) Simulation Software instead of the IE3D Zeland software used in the paper. My base paper is

We would like to create an IT solution to charge automatically customers that go into a private parking. Users getting into the parking will be identified using antennas and arduinos reading RFID stickers attached to the cars. When the user goes inside the parking the antenna reads the RFID the barrier will go up using a relay and a timer will start calculating the rate that the user will pay when it leaves the parking. The software will be capable to automatically charge the amount of money to an E-wallet, that will be automatically topped up each time the balance goes below $5 USD ie. All the UI will be using smartphones.
