I need someone who can replicate the attached FPCB with a IC. The IC has a simple function so it shouldn't be to hard to create. I have the Gerber files of the board. I also have the board. This board will be put into a controller which has roughly 20 buttons on it. I want to add extra tact switches to this controller which is what this FPCB is for. The tact switches are connected to the FPCB board via M1 M2 M3 M4 (see picture). The 37 conductive points connect to the controller so that we are able to re route all of the buttons from the controller through the IC to the M1 - M4 points. The function of the IC: 1) The board has 37 conductive points as you can see from picture. 2) 5 or 6 of them points are for ground. 3) The rest are button functions. eg Button 1, Button 2, B3, B4, etc.. 4) M1, M2, M3, and M4 on the board will be connected to external tact switches. when i hold down tact switch for 10 seconds along with another button on the controller, tact switch becomes that button. eg, if i hold down button 5 on the controller with M1 tact switch, M1 tact switch becomes button 5. The LED then lights to notify the user of the change. I have the gerber files of the board without the IC which i will need adapted slightly. I also need to add the IC and the software for the IC. Ps i hope ive described that well enough. Any questions are welcome.

Hello, I am looking for someone who is in the field of wireless communication, specially in OFDM SYSTEMS area. The project is about Constant envelop OFDM systems (CE-OFDM) by using frequency modulation and digital pass-Loked Loops (DPLL) or Frequency Modulation (FM) instead of PM (Phase Modulation). If you are not OFDM guy, please do not interrupt me. I need analytical model and simulation, then compare them together. The CE-OFDM is available in the literature. Contact me for more details.Thanks

I'm looking for a electric / electronics specialist to help me to design an economic solution for backup 4 computers, 1 router, 1 switch, 4 access points (1.5Kw) for at least 4 hours when commercial power was cut. It's not usual event, but it can happen once a month, so I would need that UPS feeds with energy for at least 4 hours. I was reading on internet a good option could be using gel batteries, inverter and circuit to charge batteries, control battery voltage, . It's just an idea, I'm pretty sure you will have a better proposal . By the way, the equipment use 220v. On the other hand, would it be possible to make double conversion from AC to DC and DC to AC for feeding my equipment when commercial energy is ok, I would like to protect router and switch from harmonics. Please, contact me to give you more detail and talk about your proposal. Thank you so much for your attention Robert
