Thanks for checking out my kickstarter campaign. This is my eighth campaign, and I'm hoping to create several more in 2015!
As of recently, I've been playing around with fingerprint scanner modules. I love them! These babies are accurate, and can be used for just about anything! I've put together two boards for this campaign.
Stretch Goal Update (February 2nd/2015):
The stretch goal hardware is now in stock! I have completed programming and testing on the port expander DIY kits! I've created a video below that offers details on how to use it. I'm hoping that we can hit this stretch goal! If we do, than anyone who pledges to a hardware reward ($80 or higher) will receive a kit at no additional expense! I will be providing an assembly video as well! If this stretch goal is not met, then I will make these kits available at cost (Under $5).
Added January 9th/2015: NEW STRETCH GOAL!
A thousand thanks to those of you who have made this campaign so successful! I am sincerely grateful! If we are able to hit a new goal of $6000, then everyone who pledges to a reward tier of $80 or higher will receive this port expander DIY kit!
This port expander kit will be extremely easy to assemble, and adds the DIY element to your pledge. Currently, it will connect to the "IN" & "D" outputs on the version#1 project board, and will allow for the users to easily add TTL compatible outputs that correspond to ID slots 8 though 20. You will have the option of having these outputs toggle on or off every time a programmed fingerprint is recognized (Latching mode), or have the relative output turn on for about 500ms, then turn off (Momentary mode). For instance, if this board is hooked up to the version#1 project board, and the fingerprint associated with ID slot#14 is recognized, then output#14 will either toggle logic (0v/5v), and stay at that logic until that same fingerprint is recognized for a second time if set to latching mode, or output#14 will turn on for 500ms, then turn off every single time the fingerprint associated with ID slot#14 is recognized. Whew! Talk about a run-on sentence! =D
As for the version#2 board, I will be making this DIY kit compatible that this board as well. I just need some time to get the programming sorted out. I will be providing lots of project updates relating to this! The PCB is fully designed, and I'm going to be ordering some for prototyping! If I have your pledge, and we're able to hit this goal before the 30 days are up, then everyone who pledges $80 or more will receive one of these kits, complete with a detailed assembly video!
Now, back to the Kickstarter Campaign!:
The first board (Version#1) is an Arduino compatible project board with a keypad and LCD. You can toggle 5x I/O lines, control a servo motor, a relay, etc. You can also program in up to 20x unique fingerprints into EEPROM memory with ease! I still have some programming to do on this board, but it will be completed within the next two weeks. This board will allow for users to interface with their own projects within minutes of opening the box! The first revision of the PCB had a small error, which has since been fixed. The hardware for this board is now production ready. I simply need to make some software additions/optimizations, and we'll be ready to roll! In the picture below, you will see that I've mounted the fingerprint scanner to a generic PCB. You can mount yours to whatever you'd like!!!
Version#1 Board Introduction Video:
The second board (Version#2) is a dual fingerprint scanner unit. The function is much simpler. The idea for this unit came from Terminator 2. At the end of the movie, a door must be opened by turning two unique keys at the same time. Well this is the same principle, only the unit requires two programmed fingerprints to be entered at the same time. Five fingerprints can be programmed into each of the two fingerprint scanners. If two fingers are pressed to each of the fingerprint scanner units at the same time, and both fingerprints match saved print data, then the on-board relay will turn on, and stay on until you press the on board "SEL" button. At this time, the relay will turn off, and the fingerprint scanned LEDs will also turn off. You can use the relay to control an electromagnetic solenoid, 120-240VAC devices, connect power to an electromagnetic door lock, etc. Best of all, it is extremely easy to use. The function is extremely simple, and the unit is extremely easy to use. This PCB is ready to go! No problems here. I just need to make some software additions, and add some security.
Version#2 Board Introduction Video:
As with all of my previous campaigns, getting rewards out on time is my #1 priority. I always to my best to keep people informed. I see no reason for any kind of delay here. Due to the fact that there is so much necessary hardware, I tried my best to keep reward tiers to a minimum for this campaign. If you are interested in a reward that is not listed, send me a message, and I'll see what I can do =)
The Fingerprint Scanner & 4-Pin Wire Connector:
This fingerprint scanner comes with a 4-pin plug in that connects easily to the main board. There are two plastic mounting tabs on each side.
What Still Needs To Be Done:
The revisions on the Version#1 PCB is complete. No revisions need to be made to the version#2 board. However, there are several software additions and optimizations that I will be making. For the version#1 board, I will be adding momentary and latching modes of operation for the 5x interface-able outputs. I also need to allocate a function that includes ID slots 8 to 20. ID slots 8 through 20 will have a much simpler function, but I still have yet to implement it. For both the Version#1 and Version#2 boards, I need to add a higher level of security. While these boards are mainly for your own projects, I still want to make them more difficult to hack, and because I still have several I/O lines to spare on each board, I have a few ideas in mind. As I make these additions and optimizations, I will be updating you through project updates.
How The Money Will Be Spent:
Unfortunately the components required for this campaign are quite expensive. The majority of the funds that this campaign brings in (If successful) will be put towards having a ton of both the version#1 and version#2 boards professionally assembled. I also wish to bring in a solid stock of fingerprint scanner modules, and all of the other accessories required by these board sets. The remainder of the funds will go to upcoming fingerprint scanner prototype units that I have in mind. I'd like to make a product line that features fingerprint scanner units.
There will be a detailed assembly video, as well as a detailed written manual. People all learn in different ways. I want to make sure that there is as much information available as humanly possible. At the end of each of my campaigns, I create a product documentation page on my website and share the link to pledges. This page will have the written manual available for download in both Word and PDF format. There will also be links to each of the relative video manuals. One link is all that you need!
In the first two weeks of this campaign, I'll be readying orders for components and working on software optimization. At the end of the first two weeks of this campaign, I will have a good idea as to whether or not this campaign will be successful. At the end of the first two weeks, if all goes well, then I will be purchasing all of the components, and having them shipped to my manufacturer for assembly.
At the end of the third week, my manufacturer should have all of the components. At this time, they will begin the assembly of the units. The AC adapters, micro-servo motors, and fingerprint scanners should be on route to me as well. At this time, I should have completed all of my software optimizations. All of this information will be shared. You will not have to go looking for any information =)
At the end of the fourth week, this campaign will be in it's last days. Assemblies should be in transit, and I should have all of the other components required for shipment in my possession at this time.
In the two weeks following the end of this campaign, I will be readying the video manual, the written manual, and testing the boards for shipment. There will be several project updates during this time. Every board set will be quality tested prior to shipment. At the end of this two week period, I will have received the funds from Kickstarter, and I will have begun shipping rewards out. That is, if this campaign is successful.
If you've made it this far, thank you! I realize that there is a lot of information to consider. If you have any questions, send me a message directly through Kickstarter, or through firstname.lastname@example.org. I will get back to you ASAP! I have several goals here. I want to run a sucessful campaign, and I want to give you the best bang for your buck that I can. I am always honest about where I'm at, and I always finish what I start. You won't have to worry about this project not being completed. That is a promise. Thanks so much for visiting my Kickstarter campaign!
Risks and challenges
My priority is to get your reward shipped out to you on time, and is excellent working condition. As with my past kickstarter campaigns, I see little risk here. The only risk would be a short delay in shipping, and I really don't see that happening. If on the off chance I purchased too few boards to be assembled (It has only happened once before), then I would need to get the remainder assembled immediately, and this could cause a delay of a week or so to a percentage of pledges. However, I really don't see that happening.
The software will be completed well before the end of this campaign, and I have a great relationship with my manufacturer, and component sources. You can count on me to keep my word. If you've pledged to one of my previous campaigns, you know how dedicated I am. If I am lucky enough to have you as a pledge, then know that I won't let you down!
