- Open house – (2PM till 6 PM) Never been to a hack space before? This is the perfect time to visit! We will give you the grand tour of the space. There will be a BBQ on site during the day if you want to bring something down to cook.
- Super Happy Hacker House – (9 PM – Late). SHHH a social night where members and non-members are welcome to gather for conversation, beverages, lightning talks, and super happy hacking. Bring your laptops, Arduinos, crafts, and gadgets for a night of merry making!
- Lightning talks – (11PM). Lightning talk is a short presentation on any subject that you want. Unlike other presentations, lightning talks last only a few minutes (2 min or less) and several talks will happen in a single period by different speakers. Challenge coins will given out to the people doing talks. Here is a video of some of our previous lightning talks
Do you have more devboards than you have projects? Is the teetering pile of boards threatening to topple and crush a household pet? Do you have a google alert for “arduino compatible” on kickstarter? Can you use boards running “blink” instead of christmas lights? Are the sketchy radio dev boards heating your house, and cooking eggs in their shell if you put them on the workbench?
It might be time to admit that you have a problem – and then celebrate that problem with the rest of us!
Bring your boards down for a collaborative show and tell.
This week we’re building Logic Pirate open hardware logic analysers at VHS in our SMD workshops. The ICSP header is 0.05″ pitch so I came up with a top and bottom programming jig to load the initial firmware. Tickets are closed, if there is demand we’ll re-run the workshop later this year.
The LP is currently OOS at Seeed (http://www.seeedstudio.com/depot/Logic-Pirate-p-1750.html), I’m selling the extra PCBs on Tindie (https://www.tindie.com/products/TomKeddie/logic-pirate-dangerous-prototypes-pcb-only).
The doco page on the LP is at http://dangerousprototypes.com/docs/Logic_Pirate. As above you need a pickit to program the initial bootloader and firmware image. The hex file can be found at http://dangerous-prototypes-open-hardware.googlecode.com/svn/trunk/Logic_Pirate/AN1388_Source_Code_V2012_10_05/PIC32_Bootloaders/Firmware/logic_pirate_combined_2013-06-25.hex.

VHS and Vancouver Mini Maker Faire are closely associated. The 2014 Maker Faire will be at the PNE like last year, it is only 3 weeks away. This year, for the first time, a selection of excellent workshops are running. You can find more details on the web site. Some of the workshops are run by VHS members, support them and sign up today!
The dangerous prototypes logic pirate is a new 8 channel logic analyser design from the home of the bus pirate. It uses the open SUMP protocol supported by the ols java client software (Mac, Windows, Linux).
This project is of similar difficulty to the internet of things arduino, except none of the chips are so fine pitched (the usb connector is however). There are parts on both sides. The board is very small 3cm x 3cm making a nice compact tool. If you are a competant with through hole soldering you can easily tackle this project.
It is recommended that you bring your own soldering iron, tweezers and magnifier, limited supplies are available. It is not necessary to arrive on time, please arrive when you can and plan to attend catchup nights if necessary. Practice boards are available for use before you start your project.
From the website….
Here are some of its features:
- 8 channels
- 256 kSamples recording size
- 60 MHz (overclocked) sampling rate (20 MHz and lower non-overclocked)
- No compromise when combining the values above
- Simple configurable edge detection triggers on all inputs (simple OR trigger)
- Configurable ratio of samples from before and after the trigger (rolling sample buffer)
- 5 V tolerant inputs (LOW-level voltage < 0.8 V, HIGH-level voltage > 2.0 V)
- About 500 kB/s transfer speed to the PC (256 kSamples take about 0.5 seconds)
- Data capturing can be stopped from the host software anytime
- Cross platform host software for Windows, OS X, and Linux
- DIY-friendly 0603 parts and SOIC packages used on a 2-layer board
- On board 3.3 V regulator can supply up to 400 mA to an external circuit
- Tiny 3cm x 3cm PCB
- Firmware updates via built-in USB bootloader
- Probe cables and acrylic case available from Seeed Studio
- Open source PCB (EAGLE) and firmware files
Some features of the host software:
- Precise measurement by using up to ten free placeable cursors
- Automatic period, frequency, and duty cycle measurement
- Displaying channel groups as HEX values and/or as an analog signal
- Analyzers for a large number of protocols: 1-Wire, I2C, JTAG, SPI, UART, etc.

In light of the cancellation of the VTL workshop, we’re going to do an alternative spring cleanup!
Things to be done:
Setup a filing system for the laser cutter wood in the workshop.Thank you, mystery people!
- Create a breaker separation for the kitchen area.
- Run (extra/temporary) network cables from the ceiling to the worktables.
- Do an inventory of the power distribution around the space.
Do an inventory of/label all the containers to their respective shelves. Thank you, Yuri!
- Take an inventory of/label stuff that can be removed or needs further sorting/attention.
- Clean up the clutter around the space.
- Remove all of the boxes from the floor and vacuum/remove dustbunnies.
- Mop the floors.
- Whatever else comes to mind!
Keep an eye out for when VHS is open on http://isvhsopen.com/ and come join us in pumping some of that spring air through the space!

You can see from looking at the block diagram above that the isolation is transformer based, it’s quite remarkable that they can fit 5 transformers in such a small package. If you can’t attend the workshop the pcb files can be found on github and all the parts at Newark/Element14.
Newark/Element14 have an excellent video from Analog Devices embedded in their product web page for the ADUM3160/4160. I’ve embedded it below.
When: April 17th and 24th 7:00PM
As part of the recent pi protoplate/connector group buy we included funds for Adafruit, the authors of the open hardware PCB design we chose. We ordered 25 boards and aimed to include $1 per board kickback for Adafruit.
The final numbers are $169.54 paid after paypal fees, the pcbs were $80.55 inc shipping and the connectors $55.40 inc shipping (from Adafruit).
This leaves the $33.59 to be sent to Adafruit today. This leaves 33.59 for oshwa.org.
It’s important to realise the open hardware is free to use but not always free to create. Where possible, always try to offer some benefit to the designer of the product even when they haven’t explicitly asked for it.
