Over at Tindie, there’s a bunch of cool things.
The EasyVolts was an IndieGoGo campaign back in Weekly Roundup #36. Well now you can pick up version 3 of this handy power supply from Tindie. It is an adjustable power supply that is controlled via USB or UART, providing from 0 to 24V at up to 1A.
Back into the FPGA camp we have the BlackIce II, which is the 4th generation and not the second. This board runs a 100MHz clocked STM32 programmable via the Arduino IDE, but it also has a Lattice ICE40HX4K FPGA. 56 of the GPIOs are pushed out from this and 26 from the STM32, which is, I think, the most I’ve seen in a regular Maker board. It also provides 8 PMOD connectors.
The Maker Uno is an Arduino Uno knock-off that is pretty damn cheap. The changes they’ve made to the original design are removing the DC jack and 5v LDO, adding a piezo buzzer and LED on every digital GPIO, and changing the USB to UART bridge to a CH340 from the FTDI IC. The other big change is the price. Only US$6.00! Nice.
If you want a simple way to power your Arduino via Solar, then the PowerStick looks pretty good. Capable of providing a steady 3.3 and 5v from Solar cell and a 350mAh AAA LiPo. Max current is 300mA on the 3.3v rail.
If you’re in to gaming then the uGame is a kit running a SAMD21 with 1.4″ TFT colour display, speakers, 6 buttons and LiPo charging supporting the ubiquitous Nokia BL-5 battery. Runs micropython with 10 games builtin.
Most of the blind controllers I’ve seen so far have to be powered externally via a wall wart or non chargeable battery. This board is a shield for the Moteino PCB, (but could be used on anything really). It provides servo control, relay and LiPo Solar charging. So no more having to worry about finding the nearest GPO.
The PiON is simply a UPS for your Pi. There’s been a lot of them around and this one provides all the good features like; soft start and power off from a 7.2v 700mAh NiMH battery. But this one has a snazzy 3D printed case!
Want to power your snazzy new board, but only have a AAA battery handy? This board from Pesky Products will provide a steady 3.7v at 1A from any AAA battery. This means that you could power most devices that can handle that extra 0.3v, or use it to replace a LiPo.
Another one for those retro gamers out there. If you still own an Amiga then this board provides flash memory that will emulate a 16bit EPROM. You’ll still need a programmer that supports the F2R16 flash chips, but once you have one you can start hacking your Amiga.
Another one from Pesky Products. This breakout for the AD5592 gives you 8 channels that can be independently configured as either a DAC or ADC. Sampling can hit 400Ksps at 12bit resolution from 0 to 2.5v. Pretty handy board.
