week 13- New Jammer Circuit

As I told last week we started making a new circuit for the jammier we found from net. And had to wait for another one week to finish it fully. We are waiting for the parts we have purchased online. hoping to finish it as soon as we get the parts. Also still we are working on making our old circuit get to 850mgz. That's the frequency we want for the jammer to block cell phones.
Also we have an idea of making a EMP jammer in case if we are not succeed with the RF jammer. And planing to make a prototype and get the Mr. Kudin's and Mr. Vijay's comments on it.

week 12- Failed circuit

Last week we got few thing we have ordered online and restarted making the new circuit for the jammier. Because the jammer we were working for the last few weeks didn't work and its generating only around 450mgz frequency. So we had to start a new one. and we have ordered few more components for the  new circuit. This is the first circuit that we have make.

This week we are starting the new circuit and hoping to get good result. and same time planing on get some advises from Mr. Vijay and Dr. Roman Kudin. What need to be improve to get good result out of our circuit. That's all for the week,

See you all next  week,

week 11- Ordering more components

Unfortunately last week we had to order some electrical parts online as we couldn't find any from Jaycar Electronics. Hope we will get them by next week to continue our circuit and finish it up as soon as possible before the final presentation.

These are receipt of the electrical components we have ordered. That's includes Antenna, Inductor and a BF494 transistor. Until we get these stuff we are hoping to work on the final presentation. What are we planing to include there. Will get back to you next week. Until then see you!

week 10 making a prototype

We have started to make a prototype of the jammer this week. But its not fully completed as we have limited time to meet. But we manage to make a half of the circuit. There are more to do and Its not easier than we thought.

This is all we have done this week and hoping to finish this by next week. 

See you until next week,
