Trimming pipette tips
Posted in Tips
I saw Benjamin Judkewitz trim the fat end off of a pipette tip and stick it onto a 1 mL syringe to make a fine tip for the syringe (above). This is handy for precisely…

Nice enclosures
Posted in Hardware
Most project enclosures are cheap and ugly. I challenge anyone to find something from PacTec that Dieter Rams would want in his house.
The following suggestions might not be Rams-worthy either, but they’re a…
Introducing the Spectrino
Posted in Hardware
The Open Hardware wave keeps rolling: MySpectral recently announced the Spectrino – an Arduino based spectrometer. It’s as barebones as spectrometers go, with the small enclosure containing a diffraction grating, CCD light sensor…
Light field imaging
Posted in Hardware
Light field imaging is a very interesting approach to imaging. The idea is to use an array of microlenses in order to capture light coming from many different angles. By storing this data, it…
Microbehunter

Oliver Kim puts out a nice magazine called Microbehunter. It’s a great resource for microscope nerds. I’ve listed a few blog articles below, but actually, the full PDF issues are where most of the…
Multimeters with IR temp
Posted in Hardware
I thought I needed a $30 multimeter. But then I saw that for just a few bucks more I could get some more features. This process repeated itself until I ended up buying a…
3D Printed iPhone-to-Eyepiece adapters
Posted in Hardware
Thanks go to commenter ybot for this one. They pointed out this handy iPhone-to-Microscope mount iPhone case.
From the pictures, it looks like the prototype was printed on a Makerbot, which isn’t terribly high…
Optical recognition of resistor codes
Posted in Software
This is an iOS/iPhone app that uses the camera to optically recognize resistor color code bands. I find this interesting because I tried writing something like this one time. I couldn’t sleep at 3am after…

Sensapex piezo manipulators
Posted in Hardware
Sensapex is the new kid on the block for micromanipulators, and theirs have an ultra small footprint with 20mm of travel on 3 axes. Here are some pictures of one of the first…
Easy Arduino projects just got even easier
Posted in Hardware
The killjoy afficiando commenters at Hack a Day love to deride as unsophisticated any project that uses an Ardunio (e.g. this thread). The platform has become so popular that, to co-opt a…
DIY Heat pad
Posted in Hardware
More cleverness from Taro Ishikawa. Instead of buying a homeothermic heating pad for surgeries (these often cost > $1000), Taro used some basic industrial process control items. He bought his stuff in Japan, but similar items are available from McMaster-Carr in…
Mini oscilloscopes
Posted in Hardware
Seeed Studio repurposed parts for cheap MP3 players and made a production miniature oscilloscope, the DSO nano. I like this small tool and bought one of the first iterations (see image…
