About the ElectricalPenetrationGraph PCB
ElectricalPenetrationGraph is an open source PCB design by DavidSternLab, published on GitHub. It is a 4-layer board measuring 60 × 40 mm, with 21 components from 8 distinct parts.
Other key parts include the HVQFN-16-1EP_3x3mm_P0.5mm_EP1.5x1.5mm, SOT-23-6 and SOIC-8_3.9x4.9mm_P1.27mm. By type, the board carries 6 capacitors, 2 ICs, 2 modules, 2 connectors and 1 relay.
From the project
An open, modern redesign of the Electrical Penetration Graph (EPG) recording rig — new hardware, firmware, and software — to replace the commercial Giga-8dd (EPG Systems EU / W.F. Tjallingii). Used to record stylet-penetration / feeding behavior of the pea aphid Acyrthosiphon pis
An open, modern redesign of the Electrical Penetration Graph (EPG) recording rig — new hardware, firmware, and software — to replace the commercial Giga-8dd (EPG Systems EU / W.F. Tjallingii). Used to record stylet-penetration / feeding behavior of the pea aphid Acyrthosiphon pisum.
1. Improve temporal resolution of sampling (original: 14-bit ADC @ 100 Hz default). 2. Reduce production cost. 3. Simplify construction. 4. Automate voltage-drift correction — the electrode-potential drift currently corrected by hand via the supplied voltage (Vs). An auto-detect/correct in firmware/software. 5.…
