Or was that resistance is futile? Your brain will be assimilated.
Working on adding some LEDs to my LEGO trains. According my calculations I need 160 ohms resistors which I don't have.
LEGO 365: Jar Jar Having A Bad Year
The recording and playback circuitry of a Revox G36 Mark III reel-to-reel tape deck, with all but one tube (valve) in a neat row, slider-ized.
Full circuit. The resistor values are 100 k (x2), and a 1 uF Nilla wafer ceramic cap. The LED load resistor is 330 ohms. (orange-orage-black-gold) The wires that are used here are the berry Twizzler strips. Note how cleanly they can be spliced by cutting them at 45 degrees and sticking them together!

Here's a shot of me just after setting up my work at Resistor Gallery in Toronto. On April 25th was my first solo art show, 'Broadcast: The art of James White'. Great time with a great crowd.
Check out the blog for more shots and write-ups.

Karel is helping me find out why the right hand channel of my DIY Mullard 3-3 Stereo amp suddenly died. It turned out to be a faulty resistor. Karel supplies DIY valve amplifier kits. See: www.marsamps.co.za/

I thought I was doing macro with chicklets and then I read about John Dohrn. No way, things could get way more macro. Ok, so I rummaged under my desk and found a 30 year old Pentax Asahi 1.8/55. Flipped it around and used electrical tape to hold it on the front of my super zoom (2.8-3.7/35-420mm). Ok, now I needed a subject. Scouring the house I found a dead fly but it didn't look so photogenic. I found a couple things with detail including this very old ethernet card.
It was lit with flash left and above on 1/4 power through several layers of white fabric and and desklamp with daylight bulb overhead. Main lens stopped to f11 and zoomed to 420mm, the adjunct lens wide open and focused short. Focused manually with the main lens. It is amazing trying focus and work with a sub-millimeter depth of field.
In this one the outer lens wasn't open all the way so got some vignetting.
These are some interesting larger-sized (higher power) resistors, from 1/2 W to (and I'm guessing here) about 3 W, with quite a range of style and vintage, and are excellent candidates to make into wine charms. The most expensive of these was about $0.20.

A bunch of 47R resistors I'm using to make an LED ringlight...
Taken with a 50mm f1.8 lens macro coupled (reverse) to the end of my 18-55mm IS lens.

Hey RESISTORS, if your on twitter, PLEASE let all of my followers know that @LtComdrData has been locked out of (my) his account for allegedly breaking the twitter rules of harassing someone / the Orange A-Hole.
I don't think my tweet constitutes harassment or any kind of threat, I just stated my opinion, what do you think ?
Since I do not own a cell phone twitter can not send me the necessary code so that I may continue in my account.
The only way that I can receive the necessary code is via my email address but twitter say's my email address does not match the one on file so I'm getting NO HELP from twitter.
@LtComdrData only hope of getting back on twitter is for someone to alert my twitter followers so they might put some pressure on twitter to unlock (my) @LtComdrData 's account.
Thank you Resistors. (:>)
Dusty electronic components (mostly resistors and capacitors) of the PCB board of a graphic card. Picture taken with my macro lens.
25ohm resistor limits charge current to 1A max so I don't melt anything. Diode in parallel with it allows current to bypass the resistor so it doesn't waste power when discharging. Each cap has a 200ohm resistor across it to bleed and balance the caps. Higher voltage caps will bleed faster and also will charge lower voltage caps adjacent to themselves.
My only worry is that after many charge/discharge cycles without ample time to balance, some caps will be much higher/lower than others. Their max rated voltage is 2.7V each, and with 10 in series being charged to only 24V, each cap should only charge to 2.4V, which leaves a nice 10% safety margin. We'll see...
Caps were $19, other bits were $10 or so. Rated for 500,000 cycles.
Edit: Caps seem to balance fine with the 200ohm resistors. Ended up lowering the current limiting charge resistor to 13.5ohm to speed up charging when the caps are more full. My DC-DC regulator on the locomotive is buck only, not buck/boost. Its output is set to 11VDC, so when the caps are between 0 and 11V, they do nothing. As a result, they spend very little time below 12V, in fact they only go that low when I let them discharge completely, so I'm not too worried about pulling 3-4A during the initial charge if it only happens once per day.
Due to a misunderstanding with a DC shunt and an analog ammeter, I was underestimating how much power my Big Boy uses by about a factor of 2. So instead of the caps powering the locomotive for several minutes, its closer to 1-2. Oh well, good enough for a layout with unpowered curves and powered straights.
These are some interesting larger-sized (higher power) resistors, from 1/2 W to (and I'm guessing here) about 3 W, with quite a range of style and vintage, and are excellent candidates to make into wine charms. The most expensive of these was about $0.20.

A necklace made of resistors.
After only 6 years as an engineer I thought I had enough and wanted out to look for my own style, my own life. I had all the success I could have dreamed of, they paid me tons of money and offered enough more to make me dizzy. It was great, but – not surprising to me, only to all the others – the attraction of it all remained limited. When my engineering career started to take off and soar but had lost its initial intriguing attribute of adventure I wanted to get out.
Sometimes then, in my spare time, I found myself making necklaces out of fragments of these tape player mechanisms I designed. Stuff I had myself created for very serious and absolutely non artistic purposes, stuff I surely had put my heart blood into and which – I was unsettled to see this – stared back at me now as pieces of my very own identity.
Looking back, this little playful practice at that time of making jewelry was tremendously therapeutic for me. To look at my engineered stuff from such a totally different perspective was like a revelation. Little metal pieces like springs, washers, bearings, nuts, and other utterly inappropriate objects like electronic resistors, capacitors, integrated circuits, and connectors became art. A little spiral-shaped gear wheel, that had a highly academic background and once was the solution for a huge technical problem and had gained me a lucrative patent and fame in certain circles, became an intriguing adornment for beautiful women. A series of bronze bearings of a new exotic material, that had bizarre cracks all over and given me great headaches because it never worked, looked incredibly decorative around a female neck.
Once the ban was broken, there was no stopping to “abuse” my creations for artwork. What had originally been a problem was suddenly a solution, what had a rational purpose before had now a charm. And of course, just to rediscover such ambivalence of almost private things was instructive and actually a wonderful relief. Maybe it was the silent message I gave to myself: “Hey, don’t get trapped in this identity of a smart engineer who is thinking up ‘noise making machines‘ no one really needs. And, when you see something, look again from a different angle, and keep wondering what it really is.”

Electronic components need to have their values identified somehow! These resistors each have a value of 6200 Ω, as identified by the blue, red, red stripe pattern. The gold stripe means ±5%.
We're Here! looking at stripes.
600K volts derived from 6 C cell batteries.
The final 10x up-conversion comes from the Marx generator on the right. 10 round capacitors are charged in parallel to 60K volts and then connected in series by nine spark gap switches, ideally producing a voltage multiplied by the number of capacitors stages.
At this brief moment of discharge, all nine of the metal balls in the middle tower spark simultaneously, shifting the parallel charging circuit to a series discharge (the spark across the air gap sees about 1 ohm). You can see a light source in this moment from each of the balls.
