[dorkbotpdx-blabber] OpenTechSpace list

Mon Jan 12 13:03:23 EST 2009

You mentioned eeprom programmers.

I'd suggest a universal programmer instead.

There are about a dozen manufacturers of them, data i/o, xeltex, advin,
etc...

I've done a bit of research really like this one:
http://www.eetools.com/index.cfm?fuseaction=product.display&Product_ID=311

The ChipMaxII is the most versatile single gang programmer I could find for
its price.  It will program 99% of what people are using including AVR, PIC,
CPLD's, flash, eeproms, etc...
It requires being connected to a PC running windows but I have yet to see a
good universal programmer that runs on linux or mac.

They have a parallel port version that is under $300.00 too, but you have to
find a parallel port somewhere.  :)

Although, any universal programmer with similar specs would do just fine.

Ok, I'll bite....

Many soldering stations that are temperature controlled, plus lots of 
spare tips and replacement parts.  A larger number of inexpensive (as 
long as they have quality temperature control) spares are probably 
better than just a couple high-end units.

LOTS of extra tips, sponges and other soldering iron parts.

Hot air station and preheater, for specialty soldering.  I use Aoyue 
852A & 853A and they work fine and aren't terribly expensive.

A vacuum desoldering station might also be worth considering.

Microscope on boom stand, plus a good ring light.  This is expensive but 
critical for soldering tiny SMT parts.... assuming you want to support that.

Desk lamps, probably some with the magnifying lens.

Solder, wick and flux.  If you stock a water soluble flux (superior for 
tiny SMT soldering), you must have a sink to wash the boards and a small 
low-temperature over to bake them dry.

Multimeters, digital with auto-ranging.  Spare fuses!

DC power supplies with good quality current limiting.  Current limiting 
makes the difference between "whew, that was close" and a burnt-up board.

Hand tools:
Tweezers
diagonal cutters
wire cutter/strippers
crimping tools
needle nose pliers
small screwdrivers
IDC connector press
PLCC chip extractor

Clip leads:
alligator clips
pamona mini-grabber types (my favorite)
clip-onto-chip types

power outlets everywhere (I bolted 2 of the wire mold types with an 
outlet every few inches under my desk, one on the front and one on the 
back...)

Basic function generator

Probably an oscilloscope

breadboards

I personally don't etch boards anymore... but a good number of people 
are interested in that.  I'm not going to list stuff for etching your 
own PCBs.

Possible consumables:

Wire rack with lots of wire....
#30 solid for wire wrap and point-to-point prototyping
#22 solid for breadboard connection
#24 and #18 for general purpose wiring
ribbon cable
maybe some shielded multi-conductor cable
"magnet" wire, maybe #24 size

pad-per-hole prototyping "vector" board

Resistors: 1/4 through hold and 0805 SMT
1, 4.7, 10, 22, 51, 75, 100, 150, 220, 330, 470, 680, 1K, 1.5k, 2.2K, 
3.3K, 4.7K, 6.8K, 10K, 15K, 22K, 33K, 47K, 68K, 100K, 220K and 1M
assortment of trim pots

Capacitors:
10pF, 22pF, 33pF, 100pF, 470pF (NPO types)
1nF, 2.2nF, 4.7nF, 10nF, 0.1uF, 1uF and 4.7uF (X7R types)
10uF, 100uF, larger? (aluminum electrolytic).

Transistors:
2N3904 & 2N3906
TIP120
IRF640

Connectors:
Single and dual row headers
IDC sockets
DB9 and DB25, solder cup + hoods and also PCB mount types
DC power jack and socket (5.5mm barrel, 2.1mm pin)
1/8 inch headphone jacks and sockets

Voltage regulators:
7805, 7905, 7812, 7912, LM317, LM337
LP2950-3.3

various microcontrollers (probably AVR, maybe PIC, maybe maybe TMS430)

IC sockets

SMT-to-DIP adaptor boards

Digital logic chips
74HC00, 74HC02, 74HC08, 74HC20, 74HC138
74HC04, 74AC14, 74HC125, 74AC245
74HC595, 74HC4094

Analog chips
LM358A
LM324A
LM339
LM336-2.5
NE5532
TL074
74HC4066, 74HC4051, 74HC4052
MAX232

Diodes
1N4004
1N5819
1N4148
Zener diodes, 4.7, 5.1, 6.2, 8.2, 12, 24 volt
bridge rectifiers

Crystals:
8, 14.7456, 16, 18.432, 20 MHz, etc

Hardware:
4-40 screws, 1/4, 1/2, 1 inch + 4-40 nuts and washers
4-40 threaded standoffs

Switches:
momentary pushbuttons
slide/toggle switches

LEDs in various colors, sizes

triacs and triac optocouplers

small heatsinks + thermal grease

transformers
