A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:
Proof of Concept
Explorations that test ideas and functionality.
Demonstrates the functionality of the final product, but looks different.
Looks like the final product, but is not functional.
Appearance and function match the final product, but is made with different manufacturing methods.
Appearance, function, and manufacturing methods match the final product.
We are introducing a professional RPi compatible tablet
Update: Power over ethernet (PoE) ready
In opposite to the many DIY builts and available kits, the HackerTab comes fully assembled and ready to run - but you can get a bare-bone option as well.
Instead of just stuffing a hobby-grade Raspberry Pi inside a monitor, we designed a real tablet from scratch which is running on the Raspberry Pi CM3 (Compute Module).
The CM3 is a tiny module containing the same processor as the RPi model 3B+ (four cores), but it´s intended to be used in industrial environments like fuse boxes and electrical cabinets.
The HackerTab is a fully integrated solution. The form factor is very handy and compact, yet offers plenty of space inside for expansions and integration of your own systems.
The removable silicone shell provides drop protection and splash water resistance.
We designed a product which is meant to be a carrier for your own system. You can focus on your goal instead of struggling with integrating a power management, a touchscreen, audio etc.
You can plug in your own (or third party) board into the standard Pi-HAT header and you are ready to go. There are already many boards available, for example motor control, Hi-Fi audio, LTE connectivity and many many more. The size of your custom board can be even greater than the size of a Pi-HAT. In fact, you can use the whole area inside the tablet.
And you are free to sell your own products using this device as basis.
Some ideas are:
Entertainment system in the car
Arcade game machine
Outdoor SDR / Radar / GPS
What does "professional" mean?
Fully assembled device - ready to run
Body developed by professional industrial designer
Long-year experience in electronic design and series production
Power-down by system command
Realtime clock (can wake up the tablet)
Panel- & wall-mounting
Customized ISO/TS16949 automotive TFT panel
Using only quality components
Integrated power system
Audio IN and OUT (the standard RPi has output only)
CM3 or CM3 LITE module inside
Meets RPi HAT specification
Device is ready-to-run No further assembly needed
Let´s compare the price with a DIY-Kit
Raspberry Pi 3B+ 35€
Official Touchscreen 70€
Audio IN 15€
Realtime clock 10€
So for only 84€ more you´ll get:
Handy format, but plenty of space inside
Rugged case / splash resistant
Header is free for use (no power or audio shield needed)
USB accessible from inside
Space for your project instead of stuffed wires
Size: 19cm x 12cm x 3cm Display: 7", 1024x600 Pixels RGB, touchscreen CPU: Raspberry CM3 or CM3 LITE Power: Li-Ion 3.7V / 5200 mAh / Connector Molex 5268-02A Consumption: 1200mA typical on CM3 Quiescent current: 200µA max. Charging: micro-USB, 500mA / 3000mA (autodetect) Audio: 3.5mm jack, line/mic in, line out, internal speaker 1.5W Interfaces:4x USB internal (header), two of them external as USB-A, LAN, audio in/out, micro-USB (charge/boot), Pi-HAT header (full GPIO Bank0), camera, power, speaker, Updated: Header for PoE module, modules will be compliant with PoE standard and low cost.
Audio OUT via 3.5mm jack
- using PWM (stereo)
- well filtered, good quality sound with no crackling or hissing
Audio IN stereo (24bit / 96kHz) via same 3.5mm jack
- selectable gain 0dB (line in) / +15dB (microphone)
- using I2S bus
- each audio channel (L/R) configurable either as input or output
Internal speaker with amplifier
- stereo to mono hardware downmix
- RasClock compatible - time selectable Auto Power OFF - time selectable Auto Power ON
Battery charging via microUSB
- autodetect low/high current charger (similar to a smartphone) - charging possible during normal operation - USB boot via microUSB possible (for programming eMMC)
Pushbutton for ON/OFF control
- Push ON / Push OFF
Battery voltage monitor
100 Mbit LAN
4 USB ports, 2 of them as external USB-A (full sized)
- All USB ports accessible through internal 2.54mm pin-headers
Micro-SD slot, to use with CM3 LITE Pi HAT header (standard) to use existing available HATs
- Compatible with existing RPi cameras
7" color TFT 1024x600 pixels
- capacitive multitouch - constant current dimmable backlight (no PWM, flicker free)
Vesa mount (interface for wall mounting)
Panel mount capability
Silicone protective shell (removable)
Plenty of space inside
- plug in your own boards - use it as a carrier for your DIY or commercial product
Plug-In WiFi module will be available on demand
- can be plugged into the internal USB header - will be included depending on the pledge amount
- We will provide descriptions of various test points and modding tips to give you more control over the hardware
Functional demonstration (unedited footage showing the core functionality)
Risks and challenges
We have a working prototype which has been tested for long time without showing any trouble.
The casing of the prototype has been 3D printed with laser-sintering to fit-check the injection-mould CAD data.
The device is ready for production i.e. PCBs, casing, assembly, packaging and shipping.
We have all quotations, so all we need is to press the start button.
Although we are using only reliable parts with high availability, there is currently a shortage of high capacitance ceramic SMD capacitors on the world market. We are trying to compensate for that and get all tapes before the campaign is over, so we can start production as soon as the fundraising goal has been reached.
