Deviator Fuzz Schematic

Mammoth Electronics responded to me after I pestered them about being an amateur student who is clueless on electronics. They also responded to a number of my concerns including the fact that I can swap the diodes for an asymmetrical approach and explained that my ICU chip should be fine being soldered directly to my board (even though I was reprimanded heavily and spanked for doing so). Apparently you really have to solder on an IC for a long time to mess it up, and they are pretty tough. The rep told me that he's soldered hundreds of ICs directly to the board without incident.

And the struggle continues..

I have been spending the day trouble shooting my circuit while I wait for a shipment of new components to arrive. It seems that I am receiving voltage throughout my circuit. However, it is being impeded to the point of an inaudible range. I've changed out my 0.47uF caps in my schematic just after my jFET where it appears the voltage drops abnormally, but to my dismay there has been no change in voltage. Until my new shipment of components arrives I will continue to trouble shoot just because.

Final Project - Aurycle Revisited

Pertinent information to my final project.

I'm going to have to get beach-monkey-drunk in order to buy another product from Aurycle, which I will have to do because they are the cheapest.

Wish me luck.

Update:

Well, crap.

Electronics III: Week 6

After last weeks midterm I needed to take the time to do more research on the design of my active crossover, in regards to slope of the filter. This required me to do some more math for the values of my  components. I decided to go with:

High Pass:
Resistor: 8 K Ohms
Capacitor: 10 nF
Cutoff Frequency: 1989 Hz

Low Pass:
Resistor: 15 K Ohms
Capacitor: 10 nF
Cutoff Frequency: 1061 Hz

Due to the long slope of the Salen-Key Filter I had to increase the distance of the cutoff frequency in order to achieve a better separation for the tweeter and midrange driver. Now that I am satisfied with the design its time to get the crossover on a chip.

I received my audio amplifier kit in the mail on the friday before our midterm, so I was excited all weekend to get to work. When I opened it i was amazed at how easy the kit really was. So I decided to buy two individual audio amps to power separate speakers. With help from Sudhu I realized that If I want to use my stereo audio amp for one driver I would need to electrically "Bootstrap" the circuit. This   creates more impedance and therefore more signal to a single output. I did some research and read that bootstrapping is a technique in which the output of the signal is fed back to the node that is normally connected to ground. This positive feed back loop alters and increases the impedance allowing for more signal flow. The use of bootstrapping was usually necessary in the early days of bipolar transistors and is commonly used in AC amplifiers to increase output swing.

Here is my first of two Audio Amplifiers in progress:

Moayedi - Week 5

My latest road bump is that Mammoth Electronics won't provide a schematic for me to reference. They say it's "not in their policy"...however in the meantime I've been trying to get this particular situation sorted out where I placed the wrong diode on my PCB board.I have one 1N4001 diode and two 1N4148 diodes. I accidentally put my 1N4001 diode in the wrong place, having soldered it where a 1N4148 should've been. I've asked Mammoth if this would be an issue or if it would still be ok the way I accidentally placed it. If not then I'll have to desolder (which I'm terrible at and Sudhu wants me to learn because desoldering is a valuable life lesson and it's worth me wasting all my time doing so).

Lastly, I have soldered one of my IC chips straight to my board without a holder because, surprise surprise, I'm an autistic 22 year old who's knowledge on electronics is similar to an autistic 4 year old. In the mean time, I'm trying to get everything sorted out and hoping Sudhu will stop making condescending remarks like "well I told you this in Electronics 1 and 2..." while eating a salad his girlfriend made for him out of his garden. SUDHU PLEASE JUST HELP ME!

So i have wired another double pull double throw switch as a total power controller. Also the capacitor coming off of input 1 of the chip i have doubled in size and got a louder compressed single in addition to my gain control potentiometer

Audio Electronics III - Week 5 Blog

Earlier this week, I went to Radio Shack to purchase the components (resistors, capacitors, etc.) required for building the Hand of Light.

Today, I've started building the main PCB--soldering most resistors, a few capacitors, and all 8-pin IC sockets. After putting together a fair number of parts, I realized that there are still some components I haven't purchased yet. Currently, I'm still missing resistors, polyester capacitors, zener diodes (10V), along with 5532s, the TL071P, the LM317, and the LM337.

Here's a progress shot:

Sammy T - Orange Squeezer Compressor

So this is my midterm project and i finally have it working to the best of its abilities. For the actual compressor potentiometer i dont have a logarithmic one i have a linear one and it doesnt sound as clean is i had hoped. I have added a gain knob and have taken out the previous volume knob because the gain knob still allows signal through when its all the way down. The volume knob does not. i took it out by simply pulling the potentiometer out of the circuit and running a single wire between the two spots of connection. I have a double pull double throw switch set up as a bypass. Later i would  like to get better potentiometers and make this a very good working compressor.
