The requirements I need to meet are as follows: The controller must support a minimum of two Roland padsThe controller must be able to replicate the soundset of the Alesis Samplepad it will be replacingIt must be easy to add new soundsIt must be simple...
A basic wiring diagram is shown below: However, you'll find no detailed step-by-step guide here, as the precise assembly and wiring is very dependent upon the particular frame and components you choice. For advice on the mechanical construction and component...
ABAX RFID 1 appears to be now and obsolete device, which is why there may be quite a number of those floating around, ending up on hacker's desks. The design has an interesting "flaw" seen sometimes in battery powered devices, the two batteries connected...
This comes out of two things, one people like blinky toys, no matter how cool a thing you make, blinkenlights just has a mass appeal. To make it a bit more interesting i've added the ESP8266 and some I/O ports.It is basically a remix of my WiFi Xmas...
Overview: This craft is based on existing design by Flite Test for a flying wing style aircraft. It composed entirely of paper-line foam project boards (like the ones your grade school presentations would be glued to). These are available...

This project consists of two microcontrollers working together, an ESP8222 (lock) and an Attiny45 (key). The general idea is that the Key contains a secrete code that must be communicated with the lock in order for the lock to perform an action. This...
Why is gifting flowers considered such a beautiful present when the plant will already die only a few weeks or even days later ? On the quest to finding an always-blooming flower, the idea of using PCBs with bright shining LEDs quickly came to the engineering...
In this project, we are trying to drive a BLDC motor in very low speed. This means we need to have a very low PWM values update rate. However, the PWM values update rate is constant, the rotating speed of motor's rotor may not being what you expected....
See the description above, regarding the Binary Ice Clock and 7-seg Binary Clock, which largely inspired this venture! For several years, I developed "avr-lvds-lcd" aka "LCDdirectLVDS", which enables an LVDS-interfaced LCD [such as from a laptop]...
I'm building a custom 3G router for all my Internet needs. It's going to be portable, with battery backup enough to get through about half a day with more or less active 3G usage, able to be charged using 5V, so any USB socket would do if I needed network...
CircuitThere isn't that much to say about the circuit itself as the AL3050 makes things so simple - I just followed the schematic provided in the datasheet . The AL3050 has an internal MOSFET and internal diode, so very few components are needed - an...
So I wanted a small clear container to hold my mini projects. I found these Amac plastic boxes at The Container Store and they are fairly inexpensive. The 1"x2" ones are about $0.59 apiece. So I bought a clear one and a smokey one.Taking some quick measurements,...
DataThe first step was to get the solar data from my Growatt 3000MTL inverter online into pvoutput.org, which is a great tool for uploading and comparing PV data. The method for getting the data into pvoutput is beyond the scope of this project (but...
Power I 'upcycled' a portable battery bank that you can buy almost anywhere for just a few dollars. These little banks almost always have the same kind of standard Li-Ion 3.7 volt batteries inside. They are reliable and easy to work with (Li-Poly battery...
