This posting is for the delivery of a schematic and PCB design and layout of a 40W, 110V, 60Hz sine wave inverter. This includes design documentation and all files (GERBER, etc) required to manufacture and modify the design in the future. The incoming power will be from four of the attached lithium-ion batteries, arranged in a 4S configuration, which are already regulated to a 4.1V maximum charge by another circuit. Therefore, maximum input for the inverter circuit will be 16.4Vdc. Circuit size should be no more than 3x2x1" (LxWxH), and the smaller the better in all cases. Height is of highest concern, but overall size should be as compact as possible. The inverter will be in an IP56 minimum container, so heat generation is an issue to be mindful of - heatsinking to the outside is possible, but a design that generates little-to-no heat is ideal, and should be possible with this low of wattage. Audible noise should be non-existent - transformer selection should be of high quali...

Hi! I am a student in Parsons The New School for Design I am a product design major, and I'm currently working on a project which invoves electronic engineering. I'm making a toy wand with parts like the accelorameter senser, LEDs, audio, speaker, and a dc motor. Basically, the sound player and speaker will be activated when someone swings the wand, which from what I understand is the accelorameter detects the movement, sound then is created.... I took apart a similar product i bought from toyrus :  [obscured]  /p/disney-sofia-the-first-royal-musical-fan/-/A-15145503?ref=tgt_adv_XSG10001&AFID=google_pla_df&LNM=15145503&CPNG=Toys&kpid=15145503&LID=34pgs&ci_src=17588969&ci_sku=15145503&kpid=15145503&gclid=CMzpy8yf_sQCFdgdgQodLpgAZA It's a toy fan that creates melody when movement is detected (swinging and Waving.)

Hello, we need to fabricate Time delay timer. Please review specifications below and let us know if you can manufacture similar timer. If you can't do something close please do not offer other types of circuits, since we do not need them. We need 500 pieces. It will be used to turn on five different electrical appliances in sequence with 1/4 to 1 second delay. Specifications following: 1. Has 5 individual channel lines for connecting wires. 2. Delays for 1/4 to 1 second each channel line; Time increments can be chosen and set from 1/4, 1/2, 3/4 to1 second. 3. Operate from 110 - 120V. Once 120V power applied to timer after half of the second delay turns on first line, then after 1/2 sec turns on the second line, then after 1/2 second - third, fourth and fifth. 4. Can be combined with similar delay circuit. If connected together, after fifth line turned on power transfers to the second delay circuit board and after 1/2 second turns on first line, then after 1/2 second - second, thir...

We are looking to build two versions of the PCBA with two schedules: 1. Power Only PCBA ? Take the raw DC 5V / 1.6A power from the charging unit, run it through a Boost Converter, Charge Controller, Microcontroller for LED, LED lightpipe (Bivar FLPR4.0-SBC), and other necessary inductors, etc. This version does not have a battery, protection circuit, or charge controller (for the battery). Essentially, this PCBA is a USB charger without the AC to DC conversion. 2. Power & Battery PCBA ? Requirements are attached. Everything on the Power Only PCBA with the requirements of an extra battery (1S1P protection circuit with thermistor). We own many Tenergy 30262 batteries and would like to use them. Testing: Both units must pass FCC testing and any other required testing. The battery unit must pass DOT tests. Schedule: Power Only PCBA is ASAP. Power & Battery PCBA target is end of May. Please feel free to contact me with any questions. Look forward to receiving ...

Update: After a long discussion with my insurance agent, I've removed the design insurance requirement. I am looking for a electronics design partner to create two printed circuit boards for a robotic lawnmower. I am price conscious and interested to learn about any price trade-offs that are available. I believe I want two boards as follows: The base station should contain a PCB that is AC powered using an external transformer. It should have basic location capabilities, an RF transmitter, a modulated infrared light, and provide power to charge the robot unit. The robot should contain a PCB that is battery powered. It should contain a micro-controller, multiple motor drivers, battery management, GPS capabilities, an RF transceiver, and infrared sensors, a small LCD touch screen, sound generation, and several sensors including one or more cameras. These boards should be in compliance with relevant US and EU regulations and standards. You should produce basic software for the sy...
