BOMtools: Python scripts build Kicad part database

Friday, June 12th, 2015

Steve Rodgers has been busy coding. He's developed a set of Python scripts (BOMtools) which allow you to extract part numbers from a Kicad schematic and match them to a part number database. There are two scripts. One which does the part merge operation and is called from Kicad and...

Another way to store your electronics components

Friday, June 8th, 2012

[embed]http://www.youtube.com/watch?v=a2k9ITFDsvY[/embed] As a response to yesterday's Workshop Video on how we stock our parts, Alvaro made a video of his own storage system. He predominately uses portable boxes, which have 4 removable compartmentalized containers. We also talked with Alvaro at the Bay Area Maker Fair 2012, and his wireless friend...

WORKSHOP VIDEO: Parts we stock and part storage

Thursday, June 7th, 2012

[embed]http://www.youtube.com/watch?v=PJnaqTe7XiI[/embed] What parts do you stock, and how do you store them? In this workshop video we cover: The common parts we stock and try to use in every design Substitutions and shortcuts we take when building a prototype How we store our parts Sources for most of the parts...

Soldering Iron Driver v1.5 Mouser order

Friday, March 23rd, 2012

S7726 shared his Mouser part order for the Soldering Iron Driver v1.5. This board is still under development so we haven't yet decided on all the parts we will use. One thing to note is to follow the partlist on the project page, as the schematic has some errors in...

Arena PartsList free BOM management tool

Wednesday, February 1st, 2012

Nabilt tipped us to Arena PartsList. It's a BOM manager that's integrated with the Octopart component database. It has neat functions like auto-fill, that automatically adds a part to your database directly from a sales page of a electronics component distributor like Farnell, Digi-Key, Mouser, etc... Octopart just tweeted a...

Partlist Wednesday: Lithium-polymer battery charger chips

Wednesday, November 2nd, 2011

Lithium-polymer batteries are an excellent choice for portable projects. They are relatively cheap, hold a significant charge, and last for a long time. The drawback with these batteries is that they require rather complicated charging protocols. You have to watch out for overcharging, undercharging, overheating, etc... We are looking for a...

Partlist Wednesday: Tantalum capacitors

Wednesday, September 28th, 2011

Every Wednesday we highlight a component from the updated Dangerous Prototypes partlist. This week: tantalum capacitors. We use tantalum capacitors sparingly, usually only when a datasheet specifies. The element tantalum is a conflict mineral, and it's expensive. For example the PICs on the Logic Sniffer and Bus Pirate have an...

Partlist Wednesday: Clock sources

Wednesday, August 24th, 2011

Every Wednesday we highlight a component from the updated Dangerous Prototypes partlist. This week: clock sources. As always, there are footprints for all these parts and more in our public domain Cadsoft Eagle part library. In our workshop the first rule of crystal selection is 'use a surface mount HC-49/US...

Partlist Wednesday: LEDs

Wednesday, August 17th, 2011

Every Wednesday we highlight a component from the updated partlist. This week: LEDs. Surface mount LEDs feel a bit smaller than capacitors and resistors in the same package. Despite moving to 0603 C and Rs, we still use 0805 LEDs. It's not just because we're stuck with a reel of...

Partlist Wednesday: Ferrite beads

Wednesday, August 10th, 2011

Every Wednesday we highlight a component from the updated partlist. This week: Ferrite beads. We usually use ferrite beads as a power supply filter. You'll find them on the USB supply in circuits with an FT232 USB->serial converter chip, like the Bus Pirate, and on the ethernet interface of the...

Partlist Wednesday: NPN transistors

Wednesday, August 3rd, 2011

Every Wednesday we highlight a component from the updated partlist. This week: NPN transistors Transistors do lots of analog tricks, but we only use them to switch high powered stuff with a weak microcontroller pin. Usually an LED. See the IR Toy, #twatch, PICqueno, or USB POV Toy for the sad truth....

Partlist Wednesday: Buttons and switches

Wednesday, July 27th, 2011

Every Wednesday we highlight a component from the updated partlist. This week: buttons and switches. Let's talk buttons. The 6mm button is the classic button. It comes in surface mount and through hole versions. The 6mm surface mount button, DTSM-6 seems to be one package name, has nice beginner-friendly pads...

Partlist Wednesday: Voltage regulators

Wednesday, July 20th, 2011

Every Wednesday we highlight a component from the updated partlist. This week: regulators. This week's part: voltage regulators. We try to use the cheap 150mA voltage regulators in SOT-23 package whenever possible. These are cheap (from 25 cents in 1s) and super resilient to shorts, over temperature, and over load....

Partlist Wednesday: Resistors

Wednesday, July 13th, 2011

Every Wednesday we highlight a component from the updated partlist. This week: resistors. If you don't have a cheap resistor kit with common values, head to eBay and get one now. It'll prevent last minute part orders and project delays. Sjaak likes this kit from MDFLY because it comes in...

Partlist Wednesday: Ceramic capacitors

Wednesday, July 6th, 2011

Every Wednesday we highlight a component from the updated partlist. This week: surface mount ceramic capacitors. Ceramic capacitors are cheaper than aluminum and tantalum SMD caps, but come in smaller values. Typical values are in the pF to 1uF range, but we've noticed some 2uF+ ceramic caps at Mouser recently....

A simple part: Pinheader connectors

Saturday, June 25th, 2011

From the Dangerous Prototypes partlist: pinheader connectors. 0.1" (2.54mm) header is the standard width of bread boards Straight and right angle versions They are used on every project we've made so far. Their standard pitch spacing makes them easy to use with breadboards, jumpers, and wires with female connectors on...
