Hi, I'm Chris, and this is Raspiado, the first USB hub designed to fit perfectly on Raspberry Pi, provide power, and add USB ports.
***Now updated to support Raspberry Pi Model B+ as well*** more info here
I designed Raspiado (pronounced "Razz-bee-ahh-doh") to solve 3 problems that I had when working with the Raspberry Pi.
Problem 1. Power
Raspberry Pi needs 5VDC and at least 1A via the USB micro connector to keep things running smoothly. That 1A is split between all the things in your project; the RPi itself (~700ma), the camera module (250ma), GPIO (up to 50 ma); and doesn't include any peripherals like a keyboard or a mouse. The easy way to provide enough current is to use something like a cell phone charger that provides 1+ amps.
Problem 2. USB Ports
Problem 3. Mounting
That's where Raspiado comes in
Raspiado solves all of the above problems with these features:
- Power your RPi without a bulky and awkward hub with a dedicated USB port on the Raspiado
Expands the number of usable USB ports on your Raspberry Pi from a paltry 2 to the 5 devices you've always dreamed of
- Provides enough power to use all of those devices
- Leaves the top of your Raspberry Pi and its GPIO & camera connectors open to whatever you're building
- Mounting holes that match up to the Raspberry Pi allow you to stack Raspiado like a delicious sandwich or use the included M2.5 standoffs and hardware to mount Raspiado however you'd like
- Sits in the same footprint as an RPi to declutter your projects
- USB 2.0 compliant, and USB 1.1 backwards compliant
- Multi-TT controller for individualized love and affection for each one of your USB devices
- Built in the beautiful state of Wisconsin by real life Wisconsinites
- 4000mA/ 5VDC power supply available
- Raspiado Circuit Board - The PCB has been prototyped and works great. I've also looked at a number of different circuit board assembly houses, and found a great manufacturing partner here in the USA and in my home state, Wisconsin, that will be manufacturing Raspiado. BEI Electronics in Franksville, WI is a great match for Raspiado and, if you believe it to be possible, they are as excited as I am about building circuit boards for Raspiado.
- Custom USB Cables - I looked at a variety of methods to connect your Raspberry Pi to Raspiado, things like an overmolded cable, a separate circuit board, and USB cables. Time and again, the cost and flexibility (mild pun intended) of USB cables had them win out over other options. The problem has been finding the appropriate orientation connectors in a short enough cable at an acceptable price. I'm happy to have found SF Cable who is going to build the custom right angle USB micro and mini cables for Raspiado.
- Mounting Hardware - The real trick to mounting hardware has been finding an inexpensive and quality way of mounting RPi to Raspiado. The typical way that I've done that in the past is to use standoffs. I provide 4 standoffs, even though there are only 2 mounting holes in a Raspberry Pi, so that you can stack them and mount your RPi and Raspiado bunk bed assembly to whatever flat surface on your project is amenable. I also include the screws and nuts for all possible permutations of mounting schemes.
- Power Supplies - Power supplies have been tested and a number of different vendors have been evaluated. I currently have 2 options for vendors, HQRP and Meanwell, and depending on the popularity of these rewards, I intend to supply Meanwell's. If you'd like to provide your own power supply, find one with a center positive DC barrel jack (2.1mm x 5.5mm) that output 5VDC and at least 2A.
Raspiado is a real and functioning product already, but in order to manufacture these for a reasonable price, I need your help to place a large enough order to get a volume discount. Besides minimum order quantities there are fixed tooling costs associated with building up a new PCB assembly and with creating a custom USB cable that I need help with.
By pledging your support for Raspiado, I can can order enough units to keep costs low and I'll be able to cover the one-time tooling charges associated with assembling a new circuit board and creating custom USB cables.
Where is your money going?
Your generous pledge will be used to place an order for 500 circuit boards and to pay for the custom tooling and minimum order needed for the 2 different angled USB cables. The remainder will cover minimum order quantities for power supplies, hardware, and to cover any fees involved.
Based on current lead times, the most conservative timeframe for this project has Raspiado shipping to you by the end of September and likely even sooner
I've got a number of great rewards to thank you for your generous support. First and foremost, any reward gets you subscribed to exclusive backer only project updates. You also get a special mention on 10LA.org thanking you for your gracious pledge.
For $10, I'll take an existing picture of you, in which you already look fantastic, and significantly jazz it up by adding a phenomenal sombrero. Think of it as a doubly-jazzy sombrerotron version of you. A hat-splosion. Perhaps someone set off a festive hat grenade. However you think of it, to thank you for your pledge, I'll be adding some sweet sweet Sombrero to your visage.
For the $20 level, I'll perform that sombrero sorcery from above AND add one of the Raspiado die cut stickers to the pot. Shown below (with an iPhone 5 for scale) these stickers will improve your vertical leap while also zapping your core and blasting your IQ (that's a good thing, you want that).
For the rest of the reward levels, to thank you for supporting me, I've deeply discounted Raspiado boards exclusively for Kickstarter backers. I appreciate your help and want to show it.
For $30 you get your very own Raspiado. It comes with the Raspiado circuit board, 2 different custom USB cable (one for power and one for USB communications), 4x M2.5 male to female standoffs to mount Raspiado to Raspberry Pi and to mount the stack to anything else you'd like, 4x M2.5 screws, and 4x M2.5 nuts. Like the other reward levels, these include your name or preferred moniker being included on the 10LA.org website and access to exclusive backer only project updates.
The Sombrero ($40), Homburg ($40), and Trilby($45) reward levels all include everything from Raspiado and add a power supply into the proverbial mix. They differ only in the style of plug used on the power supply. Make sure to choose the one appropriate to your home.
For those folks who would want a number of Raspiados to outfit their lab space or evil lair, I've packaged together 5 Raspiados at an even bigger discount of $125,or $25 per board, to get you started.
The top tier reward for Raspiado is the rare chance to own one before anybody else along with the sombrero festooned picture and die-cut sticker from the lower levels. For $275 as soon as the project is funded, I'll send you one of the fully functioning prototype boards used for testing and development up to this point as well as your sombrero emblazoned photograph. I'll also include all of the cables you'll need, the hardware for mounting, and one of whatever type of power supply you'd like. Once the production Raspiado boards arrive, I'll send you an additional full production Raspiado kit and power supply and your die cut sticker. You obviously will be given a position of great honor on the 10LA.org website, I'm thinking the top of the page, and will have access to the exclusive backer only project updates.
Special thanks to:
Joseph Bayalas and the team at Mindlabtech for their assistance in PCB layout and prototyping. If you've got a project with circuit boards you can't find a better group to work with on development.
Sector67 Makerspace in Madison for their great feedback and support during development.
Risks and challenges
I have mitigated most of the project risk by shouldering the financial and engineering uncertainties on my own already. This works, I've tested & passed it functionally as well as to relevant standards/ regulatory levels. Using industry contacts, I've unofficially passed USB-IF 2.0 Hub testing, ESD Level 3 (IEC standard 1000-4-2), and Conducted Emissions (EN 55022 / CISPR 22). Why unofficially? Official certified testing would exceed $20k for this product.
I have been in contact with multiple vendors for every major component and have carefully selected the vendors that will provide the best products at the best price. In some cases, most notably the production location of circuit boards, that has meant accepting higher per piece costs to ensure that the schedule and overall budget can be met.
I have already visited the main supplier for the PCB and identified ways to speed up the production order for components. I feel very confident in their ability to deliver exactly what they've promised, in the time they've committed to, and at the quality level that you deserve.
For shipping and logistics, customs is tricky sometimes and that's why I've spent time verifying the best method for shipment and understanding the options for getting rewards to backers regardless of where they are in the world.
Leading successful development efforts and managing the people, time, and budget necessary to get things done is what I do every day at work (see my bio for more) and based on that experience, I'm very confident and comfortable with the time-frame I've put together for Raspiado.
*********Boring project management language below this line*************
The idea of risk management is to plan for every "known unknown" and make a plan for mitigating that risk when it arrives. There's always the possibility of "unknown unknowns" but based on my experience in this field, I'm confident that regardless of what comes up, I'll be shipping Raspiado in the schedule I've outlined above and you'll have access to all the details throughout the entire process.
If this interests you, the canonical source for more info is the Project Management Body of Knowledge (PMBOK). It's currently on the Fifth Edition and the discussion of Project Risk Management starts on pg 309. If you know what that is, high-five for a fellow PMP.Learn about accountability on Kickstarter
