Paid on delivery
I need a Schumann (7.83 HZ) Frequency generator, like this model by Acoustic Revive (http://www.amazon.com/Acoustic-Revive-RR-777-Frequency-Generator/dp/B008HAQT2S/ref=cm_cr_arp_d_product_top?ie=UTF8) - or this model (http://www.amazon.com/Gen-El-P388-Schumann-Signal-Generator/dp/B00E5IKP6C/ref=pd_sim_sbs_121_2?ie=UTF8&dpID=41JGpln5vNL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=0BH0R8VR3QM70GS7ZEFX) - but significantly cheaper! I'd like it to have the same specs (AC100V Input Voltage: 100V~240V; Output Frequency: 7.83Hz) - and with any/all adapters needed for use with European power sockets. Any takers? It's not needed urgently.

Dear Valued Employer, My name is Martin Botsov and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. As I understand from the project description you are looking for a hardware engineer who would be capable of designing a Schumann (ultra low frequency) resonator unit. So, without further ado here's how the workflow would look like, if you happen to choose me as a partner for your project: 1. Initial discussion 2. Research 3. Block diagram of proposed solution 4. Schematic draft based on proposed solution 5. Component library creation 5.1 Schematic symbol library creation 5.2 Footprint library creation 6. Schematic drawing 7. Review of final schematic drawing 8. Layout design 8.1 Components placement and arrangement 8.2 Review of proposed layout design arrangement 8.3 Components routing 8.4 Review of final layout design 9. Design rule check 10. Verification and validation 11. Production files (GERBER, NC DRILL, STEP, BOM, ASM, PICK & PLACE, SCH, 2D mechanical drawing) Your project will be carried out on Altium Designer. Don't hesitate to contact me with questions regarding any details around your project. You could also check out my profile on Freelancer and LinkedIn for more details around my professional experience. I am looking forward to hearing from you soon. Thank you for your time. Kind Regards Martin Botsov

Hello, I am an electrical engineer and had build a frequency resonator before and i can get this done but it will take around a month as i have a job too :D and i am willing to work on this fun project and can build a tune-able resonator upto 50 HZ. that means u can set it from 0 to 50 hz but you will need to get a frequency detector. if you specifically want the resonator at 7.83 that is for music room purpose only in which you dont need to change the frequency i can build that too

Hi. I have an MSEE and years of circuit design expertise including magnetic field generators. I absolutely can do this. The key will be defining exactly what you are looking for, trading off cost, performance and features. For example, if you don't need adjustability (i.e. just set output at exactly 7.83 Hz), and fix the desired field strength at a suitable distance from the coil (say 10 mG), this can be done at considerably lower cost than providing adjustability. We can work out those details.
