****FULL INFO WITH PHOTOS IN ATTACHED DOCUMENT... PCB Board to be used: One option is to use a SBC like the ODROID or something similar – as an alternative we are open to suggestions for a custom made PCB design to better cover our exact requirements, in either case I’d like to know why you prefer one option over the other We would like to have WIFI function, remote access for troubleshooting, touchscreen control, HDMI port – besides the obvious required ports & functions. Machinery Function: We are generally attaching these controllers to two types of test frames, some hydraulically operated, some mechanically. Images… 1. Concrete Compression Machine - Hydraulically operated, measures stress through pressure Transducer converts to kn a. Pressure transducer is installed within the hydraulic line and measures the pressure 2. Elastic Modulus accessory on (item #1 Compression Machine) – measures displacement through a number of displacement transducers (mm) – this isn’t important to implement now as we have minimal demand on this. 3. CBR Test Frame – presses soil mechanically and measures the stress in kn on the soil through a strain gauge sensor & measures displacement through a displacement transducer sensor (mm). 4. Tensile/Compression Machine – hydraulically operated, measures stress on steel rebar using a pressure transducer converted to kn & measures displacement of steel rebar as it stretches it to demonstrate the amount it was stressed in (mm) before breaking. 5. Soil Compactor, simply rams soil into the mould using rammer that is lifted and dropped using gravity… the function of the controller is to set the number of blows on the soil specimen & the location the mould moves to for the next ramming, very easy function & no sensors. Note var%x – simply means a preset variable, set either by preset test method or through user input • Hydraulic powered frames will be powered through a servo motor or a 2 stage stepper motor which pushes oil through a hydraulic pump / The mechanical unit will simply use a motor to stress the specimen at a preset speed o The motor is powered when the user selects “Start Test” o The device will be calibrated using an external load cell with a digital readout which is put in place of the specimen and the kn values showing there are either entered manually into our device’s screen or auto feed through an output wire from the external loadcell feeding into our device. o The test will start at a faster speed (Pace Rate) until it touches the specimen, the specimen is touched once the pressure on the transducer reaches var%x kn o Once the specimen touches, the speed will slow down to either the preset test method, or the user inputted adjustable speed in kn/sec o The test will stop once it detects the specimen has broken, the specimen would have broken once it drops in var%x kn of stress or var%x in percentage of kn stress. o Once test is complete, the motor is automatically shut off, return valve is open to allow the weight of the hydraulic piston to push the oil out of the machine and the piston to its initial start position & the test values are displayed on screen in summary in the form of “maximum stress” in kn before sample failure, “test duration”, and it will draw the results into a graph with the option to print out the graph, or save… o For reference of an example concrete compression machine running refer to this page [login to view URL] • Sensors are Analog and will probably feed into a ADC pin into the board • Before test, test methods can be selected either by custom user control or preset international standards (ASTM, BS, AASHTO, etc…)

Dear Sir/ Madam, My name is Henry from PHAMTECH Co. My team is really interested in this project as it is exactly within our scope of expertise: We are web/ app design & development experts. Please kindly visit PHAMTECH to learn more about us and our works similar to this type of projects. Working with a team who has both in-house DESIGNERS and PROGRAMMERS means that you can take advantage of both: Our designers could help revise the design even in coding process, which is a GREAT benefit for any ongoing project. + We plan and build. We don't use prebuilt templates which produce conflicting codes and bugs and hurt the system in the long term. + Our team is 100% in-house. We don't outsource projects elsewhere. So you pay for the real service - not marketing fee. In short, if you need an experienced team who offers *real English* communication, beautiful design & optimized code, premium after-service, in time and to budget, then we are the choice. If you need something based on solely ONE of the above criteria, then we're still happy if you decide to give another freelancer a chance. Just bookmark our website and come back in case the selected freelancer can't meet your demands. * Even if you don't go with us, avoid fast food services. Chances are they omit the software planning & testing phases for the sake of reducing time & cost, which produces unsustainable codes behind and creates more distrust in this market! Best wishes, Henry.G
