In the back right corner of the store is the electronics department, which finally looks different from the ones we've been seeing for quite a while now. Sadly, even a 2012-era electronics department manages to look somewhat outdated in 2018, though I suppose that shouldn't be too surprising.
The location of the electronics department here is another change, as most stores have it along the front of the store. However, Fred Meyer has put electronics in a back corner in a few new or majorly remodeled stores lately, though it seems like these days they're often removing electronics as a department entirely and putting it as a much smaller section in the main part of the store.
A basic circuit for driving one propulsion motor of a tennis machine I'm building. It's half of an H-Bridge, allowing for one direction and break. A microcontroller is to be connected to the two inputs on the MOSFET driver chip.
A little firefly made of paperclips, at ATtiny13 and an LED. It capacitively senses its body to determine if it is being touched, waking up every ten seconds or so on watchdog to do this.
If it's being touched, it'l start pulsing its LED gently, flashing a random number of times for a random duration each time before going back into a deep sleep.
Part of the circuitry on a power supply board for a Western Digital MyBook external hard drive. I removed the drive and put it into my PC for extra photo storage.
I recently received the custom printed circuit boards I had made by OSH Park!
This one is for a small voltage doubler. It rectifies 12v AC current for the tube filaments of a couple of 12EL6 tubes, and doubles the voltage for the plates. I'm not yet sure how well the 100μF caps are going to smooth the current since I don't have a scope, but we'll see..
After designing it I created the board layout in Eagle. OSH made it so easy, too. No need to generate all the various gerber layers, just upload the ".brd" file and they do all that and show you nifty previews to check over before finalizing the order! They are now going to be my fab house for the indefinite future. :)
My breadboarding is too damn messy. This is an attempt at an Arduino-driven EEPROM programmer (yes, silly, I know). It's controlled via USB by my PC.
Alright, I admit it. I just like watching the lights blink, OK?
We manufacture a large number of amplifiers for our powered systems, most include the latest in digital amplification, and wireless technology for connectivity.
Fabricamos una importante cantidad de amplificadores para nuestros sistemas autoamplificadas. Estos amplificadores incluyen lo último en tecnologÃa de amplificación digital y conectividad inalámbrica.
Early attempt at designing PCBs using ExpressPCB. The green is the back of the board, the red is the top, and the yellow is the silk screen (in case I can find a cheap enough place to make me a small batch).
this is incomplete. An ECG based on a schematic from a Wright State University lab I described here. The Green/Yellow leeds going off screen are meant to connect to eletrodes, one on the wrist and the other on the foot. (a 3rd electrode should connect to ground). The AD620 IC Op-amp on the left handles initial gain. The lead from the larger capacitor (1000uF) can be put out to an oscilloscope and you should already see a heart sine wave. atm this leed goes to the first filter (the other IC in the picture). The two white wires are supposed to be a capacitor and resistor instead, but I do not have them on hand and need to get later. Finally, the orange wire going off the board is supposed to be the final output to an oscilloscope, with high,low and dual amplification having taken place. The grey wires are for negative and positive power sources. the resistor to the far left of the breadboard, is a 220ohm which can be removed.
