High Quality (and Safe) Copper Plating. There are a few copper electroplating methods on here, but they are either dangerous, provide very low quality results, or cost an arm and a leg.

High Quality (and Safe) Copper Plating

Your plated object should be a brilliant, shiny red and not blackened and your pocket book shouldn't be hit hard by chemical costs or hospital bills. The method I am writing about here is the copper acetate method. Rather than buying copper acetate pre-made, we will make it ourselves. I wanted this instructable to be as easy as possible, safe as possible, and as cheap as possible. iGeocacher. Reflow Soldering If you want to read about an easy and inexpensive reflow soldering setup, read on: But first a parts list of the "odd" parts so that when you decide to follow my bread crumbs you won't have to dig to find them later: 1.

IR Temperature Sensor from SparkFun - SEN-09570 - $19.95 2. Pansonic Opto Isolated Solid State Relay from Mouser # 769-AQN221VL - $28.28. Infrared Thermometer - MLX90614 - SEN-09570. Description: Melexis' MLX90614ESF-BAA is an infrared thermometer designed for non-contact temperature sensing.

Infrared Thermometer - MLX90614 - SEN-09570

An internal 17-bit ADC and a powerful DSP contribute to the MLX90614's high accuracy and resolution. It has a huge number of applications including body temperature measurment and movement detection. The MLX90614 provides two methods of output: PWM and SMBus (i.e. TWI, I2C). Is it hot? Arduino + MLX90614 IR Thermometer. Make Your Own Steadycam Mount. Home Made Plastic.

Hacked Gadgets - DIY Tech Blog. SparkFun. By RobertC. | October 21, 2010 | 3 comments Hello, and welcome to another exciting edition of "More New Products"!

SparkFun

It's been a couple weeks since we've announced new products, so we have a few to talk about. As you've probably noticed, we do a lot with LEDs. Here we have the Tri-Color LED Breakout. It uses our 10mm super 'my eyes are burning' bright LEDs with a transistor on each. Finally! We now have the latest version of the SparkFun Inventor's Kit out. We sell a lot of electronics for making UAVs, but not a whole lot to control them.... We always end up using GPS modules to pull down accurate time information. I could make all sorts of puns about the the hot knife, but I consider myself a cut above the rest (sorry, I had to). Sometimes you need a lot of PWM pins. To go along with our frequency counter kit, we now have our function generator kit. Flush cutters allow you to cut a bit closer than what a diagonal cutter would allow.

This next part went faster than expected. Seeedstudio-dso-nano. • 32bit digital storage oscilloscope• Portable and Lightweight• Uses black metal shell which is more durable and strong• It's compact, simple to operate The SeeedStudio DSO Nano Pocket 1MHz Digital Storage Oscilloscope is a 32bit digital storage oscilloscope.

Based on ARM -M3, it's equipped with 320 x 240 color display, SD card, USB port and recharging function. It's compact, simple to operate; meets the basic demands of school lab, electric furniture repairmen and electric engineering. The version 3 of DSO Nano differs from version 2 in that it does not use white plastic shell. BGMicro.com. Texas Instruments. Make: Online. Instructables.

After two years, I think I have my Replicator (apparently the first one shipped) finally working reliably to produce >1 hour prints.

Thank you @iandanforth for asking if I had a description of the mods I did and prompting me to write this. The Replicator has been a very frustrating product. After a few out-of-the-box failures, it worked great for the first week and then rapidly deteriorated. And a few months later, the Replicator 2 was announced and support for my product rapidly evaporated. Many of the things I print are small and take <15 minutes to print, so I’ve been dealing with a <30% success rate of printing, or using other 3d printers.

The heated build platform and thermocouple issues were just bad original parts from Makerbot. Assuming the basic mechatronics of the printer work, the most critical fix is the new extruder design. The next most critical mod is replacing those stupid plastic cantilever arms with something sturdier. « CT Simonelli. Power Strip Hack.
