Storage cabinet for resistors.
« on: August 23, 2024, 03:59:09 pm »


Because of this other thread I had a look at storage boxes for THT resistors, and this 3D printed one looks quite good.
I like the simplicity of the small flat tabs for the handles. This leaves much room for the labels, which can now cover nearly the whole front.

For an improvement...
I find I sometimes run out of room for power / shunt resistors. If this is extended with one or even two decades below 1 Ohm, then maybe make those drawers a bit bigger. Either a bit higher, or twice as wide and then make two rows of 6.

Making it a bit deeper is also an option. I don't know how deep it is exactly, but when the resistor bodies can be staggered in 3 or so levels, then more resistors fit in a smaller overall area.

I kind of like this- I've struggled with resistor storage over the years.  What I've come to for the past decade or so is to have a half decade 0-56 ohms and 68 to 560 in the next drawer with 6 horizontal dividers.  This puts two parts per section.  Picture attached.  It works OK for having a ready supply of breadboard type values but falls apart when you get past the 12/decade stuff.  These get randomly thrown in the closest value drawer or kept in the digikey bag until needed.

I also have full drawers of very coarse common 1/8W values in 100 220 470 1k progression up to a Meg.  this is for breadboarding and works ok.  These are so chrap I can throw them away rather than trying to resort them.  I don't include 150's, 330,680, etc just this 3 per decade like and O'scope 125 progression.  I buy these in the 200 per value from digikey for cheap- can't remember even. I also throw 0805's of these values in the same drawer- these have become sort of breadboard type R's these days. Photo attached.

I really haven't found a good way to deal with SMT R's and C's, would love to see some good solutions.  The little ones are like fleas and are impossible to keep together.  I tried books with plastic pages that you could insert cut tape- not all my parts are on cut tape especially after a project.  I have another system just that used little 1x1x1/2 inch poly boxes that go into a little carrier.  Not great.  I got this at hobby lobby- I think its for people that do beading?  Picture.

I worked at Maxim for 20+ years- now Analog Devices.  They had great labs; in most labs (they had dozens) they had rotating racks of cabinets about 4 feet square that had the full 1% value progression in several power levels.  They also had similar for caps and inductors.  We also had all the standard bipolars, FET's, MOSFET's especially those that we specified for use, HC, AC Logic, all standard analog including all common Maxim parts and the best of our competitors if warranted  If you wanted something else, you put in a request and you'd have it fast- usually the same day. The wildest part was that the reps would come in and keep all the passives stocked!  They would leave sample kits behind that were free for the taking. Those racks are bigger than my lab!  It was embarrassing almost.

Enjoy the pics- I've been a hobbyist since age 8 about 60 years ago after a 40 year career as an EE.  Learning every day.
