Experiment with neurostimulation using NeuroStimDuino Arduino shield (Crowdfunding)

Neuralaxy’s NeuroStimDuino is an open-source Arduino shield that allows students, researchers, and hobbyists to study the effects of neurostimulation on muscle contraction easily and cheaply. What is Neurostimulation exactly? It works by applying short electrical pulses to the surface of the skin for the purpose of stimulating the underlying nerves and muscles. Neurostimulation has several uses including a treatment called Functional Electrical Stimulation (FES) therapy to help restore mobility in the paralyzed limb muscles of stroke victims and those who have suffered spinal cord injuries, and studies are being carried out to better understand how it can be leveraged for pain reduction and sensory feedback. NeuroStimDuino hardware specifications: MCU – Microchip dsPIC33F 16-bit microcontroller (40 MIPS) with 256 KB flash memory Two independent 2mm output jack per board with: Adjustable current output range – +/- 25 mA, resolution 250 µA/step Adjustable stimulation frequency range – 1 – 100 Hz, pulse-width […]

Linux and Memory Performance on an Intel NUC 11 Enthusiast Phantom Canyon NUC11PHKi7C

I’ve already looked at Windows performance on the NUC11PHKi7C Enthusiast Phantom Canyon which is Intel’s latest NUC 11 flagship product specifically targeting gamers as it includes an NVIDIA RTX 2060 GPU. Now it is the turn of Linux and like before I will compare performance against Intel’s previous NUC with a discrete GPU: the NUC 9 Extreme Ghost Canyon. I will also briefly revisit Windows performance by looking at the impact of using 3200MHz memory as opposed to the 2400MHz used during the previous review. Hardware Overview As a reminder, the NUC11PHKi7C physically consists of a 221 x 142 x 42 mm (8.70 x 5.59 x 1.65 inches) rectangular plastic case. It is an actively cooled mini PC and uses Intel’s 10 nm Core i7-1165G7 Tiger Lake processor which is a quad-core 8-thread 2.80 GHz processor boosting to 4.70 GHz with Intel’s Iris Xe Graphics and the NUC also includes […]

Tiny Tri-color E-Ink display for Wemos D1 Mini board sells for $10

tri color E-Ink display for Wemos-D1 mini ESP8266 board

Wemos D1 Mini is one of my favorites ESP8266 boards with a cheap price, tiny form factor, and support for stackable expansion boards. Lolin has now launched a small 2.13-inch tri-color E-Ink display that is compatible with D1 mini, D1 mini Pro, and D32 Pro boards, and sells for just $9.90 plus shipping. Specifications: 2.13-inchTri-Color (red/black/white) ePaper/e-Ink display with 212×104 resolution Driver IC – Good Display UC8151D Connection to D1 mini, D1 mini Pro, D32 Pro via 10-pin connector Debugging – 8-pin unpopulated header with EPD signals (SPI, Reset, Busy…) 3.3V, GND You may wonder why the PCB reads “2.13 INCH e-Paper 250×122”, while the resolution is 212×104. That’s because the company probably reused the PCB from their 2.13-inch black and white e-Paper display with 250×122 resolution (IL3897 driver). The display can be programmed with Arduino using LOLIN_EPD, Adafruit_GFX, and Adafruit_BusIO libraries as explained in the Wiki. You’ll find three […]

Piunora has the guts of a Raspberry Pi 4 with Arduino form factor, M.2 PCIe socket (Crowdfunding)

The Raspberry Pi 4 is a pretty cool board, but if you wished it was just a bit smaller, and you could use the PCIe interface exposed by the Broadcom BCM2711 processor more easily, Timon has designed Piunora carrier board for the Raspberry Pi Compute Module 4. The solution provides a board with the guts of Raspberry Pi 4 SBC but using the Arduino form factor including access to the six ADC pins, and an M.2 socket with the PCIe signal from the Broadcom SoC. Piunora carrier board specifications: SoM compatibility – Raspberry Pi CM4 module with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 1 to 8GB RAM, optional 4GB to 32GB eMMC flash, optional wireless module with 802.11b/g/n/ac WiFi 5 and Bluetooth 5.0 Storage – 1x MicroSD card socket (for the OS when using Raspberry Pi CM4Lite system-on-module) Video Output – 1x HDMI 2.0 port up to 4Kp60 […]
