Wednesday, January 22nd, 2014We designed a microcontroller board for a power supply, but somehow we forgot to add the oscillator to the circuit. We thought it was enough to add two nets called 'OSC1' and 'OSC2' to the schematic... Why can't Eagle cope with that automatically?! The lovely photo was taken with an...
Tuesday, July 23rd, 2013Where we've been Dangerous Prototypes has been around four years this summer. This internet gig started at the DIY Life and Hack a Day blogs when I was a poor student roughing it in Amsterdam. A couple hundred bucks for a feature piece bought a lot of ramen stampot, and...
Tuesday, May 21st, 2013We continue working on the part kit models and diagrams. The images above are CAD drawings, and Eagle components of PCB edge connectors.
Wednesday, May 15th, 2013We continue working on the part kit models, and documentation. We're adding them to our Eagle part library as well. We're on our way to the Bay Area Maker Fair this weekend.
Monday, May 13th, 2013We are getting ready for the Maker Faire. Work continues on part, and kit documentation. Check out the videos and writeups from our previous Maker Faire visits.
Thursday, May 9th, 2013We continue working on part documentation. Here is a image of our 2D technical drawings of IDC connectors.
Tuesday, May 7th, 2013We continue working on the part documentation. The picture above is pre-crimped ribbon cable.
Monday, May 6th, 2013Today we worked on some part documentation. We made CAD drawings (pictured above) of 0.1'' female connectors, and 3D models to go along with them.
Thursday, April 25th, 2013Skimming through the datasheets building documentation for the Bus Pirate Edu Kit.
Wednesday, April 24th, 2013We're finalizing the gerber merging ULP for Eagle. Bus Pirate Edu Kit documentation continues to grow.
Friday, April 19th, 2013We bought the Postek C168 acetate label printer for kit projects. We continue working on documentation.
Tuesday, April 16th, 2013We tested out all the Bus Pirate Edu Kit exercises and the connection diagrams. Some alterations may be made to the real time clock exercise to make it more interesting. Rediscovered SEG market. Had ignored it as a tourist trap but, was really successful sourcing some low volume items there...
Monday, April 15th, 2013Made an initial Eagle ULP to produce a crude .cfg configuration file for gerbmerge to process gerber panelization. We continue working on the Bus Pirate Edu Kit documentation.
Friday, April 12th, 2013Final sourcing. Dinner with HAXLR8R teams. We are finalizing the Bus Pirate Edu kit documentation. Finally got gerbmerge (gerber panelization) to work, thanks to schazamp's instructables and Paul Mac's Gerbmerge wiki.
Wednesday, April 10th, 2013We're are looking into tools for gerber paneling to further reduce the cost of prototype PCBs. We continue working on the Bus Pirate documentation, and have sent out the bill of materials for a quote. QFN breakout boards are finalized.
Tuesday, April 9th, 2013We started using a professional sourcer for our kits. Will have a full report when we get results. Another batch of SMD breakout boards is designed. The one pictured above is of a 0.5mm and 0.65mm pitch 80pin QFP package. The two different pitched footprints are on opposite sides of...
Monday, April 8th, 2013We finished up all the models and renderings for the Bus Pirate Edu kit. Now we'll concentrate on writing up the documentation required for each exercise, as well as assembling the booklet that will accompany the kit.
Thursday, April 4th, 2013Today we worked on some QFN breakout board for another kit we are preparing. Another image was rendered for the Bus Pirate Edu Kit documentation, and the last model was prepped for rendering.
Wednesday, April 3rd, 2013Exercise 10 out of 12 render complete. We continue sourcing parts in Shenzhen. QFN footprints for proto-boards are being finalized.
Wednesday, April 3rd, 2013Another day, another render. This is exercise 9 of the planed 12 for the Bus Pirate Edu kit. In Huaqiangbei we tested out some part sourcing services for our parts kits.
