Project Overview:
We are requesting a quotation for the manufacturing and assembly of a low-power counter clock with custom enclosure requirements. This product must be an end-use device that includes an electronic counter and custom housing composed of glass and aluminium components.
Scope of Supply:
Counter Clock Electronics
1.1. Battery Pack: Compatible with four AA Energizer L91 Ultimate Lithium batteries in series.
1.2. Voltage Regulator: 3.3V ultra-low quiescent current voltage regulator for stable power.
1.3. Microcontroller: ATTiny85 or equivalent ultra-low-power microcontroller with I2C capability.
1.4. Display: Custom-sized 14cm X 2cm I2C-compatible display (e. G., TN DOT-matrix display).
1.5. Latch Circuit and Switch: Maintains the "on" state once triggered, non-resettable.
Program:
The program is straight forward left most 6 digits will be to display days, then 2 digit for hours and then 2 digit for minutes and last 2 for seconds. Total of 12 digits. It will start counting once triggered. It will continuiously count the time elapse and display.
Enclosure
2.1. Glass Tube Body
Material: High-quality, durable glass.
Dimensions: Radius: 4cm, Length: 16cm.
2.2. Aluminium End Caps
Material: Aluminium, with a sleek finish to match the glass body.
Dimensions: Each cap should have a radius of 4cm and length of 2cm, designed to fit seamlessly onto each end of the glass tube.
Additional Assembly Requirements
2.3 Pin
A pin with a ring made of metal or aluminium attached that allows the user to grip it by and pull.
A design on the housing is attached. Its only a concept design, The caps dont need to have groves it will remain simple.
Use:
The clock will have its pin on any of the caps. The clock will be off when the product will arrive to the customer. Once the user pulls the pin the clock will start to count seconds. This will mark the time elapsed since the pin was pulled. This will successfully become a memorabilia to look at.
The product should have capability so that if a product breaks its chip or EPROM can be salvaged and the users date is saved onto the chip. Thus placing the EPROM in a new board will revive the clock and will make up for the lost time.
Proper assembly of all components within the glass enclosure.
Connections must be robust, maintaining long-term functionality and stability.
All wiring should be concealed within the enclosure to achieve a clean, professional appearance.
Technical Requirements:
Power Specifications: The assembled counter clock should operate on the supplied batteries and sustain a power-efficient design. Estimated power consumption calculations are requested.
Environmental Resistance: The assembled unit, including the glass and aluminium, should withstand typical indoor environmental conditions.
Longevity: The system is expected to support a lifespan of up to 150 years without significant degradation of components or materials.
